Good day, ladies and gentlemen. Thank you for standing by. Welcome to the IRIDEX Corporation fourth-quarter 2013 earnings conference call. During today's presentation, all parties will be in a listen-only mode. Following the presentation, the conference will be open for questions. (Operator Instructions). This conference is being recorded today, Thursday, February 27, 2014. I would now like to turn the conference over to Will Moore, Chief Executive Officer. Please go ahead, Sir.
Will Moore - Chairman and Interim President and CEO
Thank you, operator. Good afternoon and thank you for joining us as we discuss the results of the fourth quarter of 2013. My name is Will More and I am the CEO of IRIDEX. I am joined by Jim Mackaness, our CFO and COO. Jim and I will be delivering some prepared remarks related to the quarter and to the business, and then we will open the floor questions. Before we get started, Susan Bruce will read the required Safe Harbor statement. Susan?
Susan Bruce - Executive Administrator
Our discussion today will include forward-looking statements, including statements regarding the adoption of our products, including our MicroPulse product offerings, trends in the domestic and global healthcare markets, planned product releases and development efforts; the success of a reorganization of our sales and marketing teams; and the result of our education sales and marketing campaigns; sales of our consumable products; and the anticipated mix of sales of consumables and capital equipment; our long-term margin goals and performance against those goals; our anticipated first quarter 2014 operating and financial results, including projected revenues, gross margins, operating expenses, and operating income; and our goals to turn IRIDEX into a more commercially oriented market-driven company and leverage the respected IRIDEX brand. And the anticipated scope and growth of our diabetic macular edema and glaucoma businesses and product offerings.
Forward-looking statements are only predictions and involve risks and uncertainties that may cause our actual results to differ materially from those expressed or implied by these statements. Factors that may affect our results are summarized in our quarterly release and described in detail in our SEC filings.

Will Moore - Chairman and Interim President and CEO
Thank you, Susan. I am pleased to begin by saying the fourth quarter of 2013 was another record quarter in terms of ophthalmology revenues. This was our fifth consecutive record quarter, and we demonstrated strong performance on all operational fronts. Our revenues for the quarter were $10.6 million, a year-over-year increase of 15%, and more than 10% increase sequentially over the $9.5 million for the 2013 third quarter.
Revenue for the year was $38.3 million, setting another record for ophthalmology sales during a one-year period and up more than 10% on 2012. We believe this strong top-line growth is evidence that we are gaining market share and increasing traction in the marketplace for our innovative products. As those of you who follow us closely know, since I became CEO, our primary goal has been transforming IRIDEX from a respected research-oriented company to a successful market-oriented company that moves faster and has more growth and profit potential.
We now believe our new commercial model has evolved to the point where our fundamental building blocks are in place. That is a substantial accomplishment, one that gives us confidence that our strategy is sound and will continue to drive shareholder value going forward. We made some important moves over the last 18 months to get here, including some key personnel changes in product development, sales and marketing, and are making adjustments to our sales channel.
As we have discussed in the past, we sought partner relationships that would help us implement quicker product development cycles. The global distribution and supplier agreement with Peregrine, which we announced last April, is a great example. Working with a high quality manufacturer like Peregrine will allow us to drive costs out of our supply chain and help us accelerate product development cycles for new disposable products -- all very important parts of the new, more agile commercially-oriented IRIDEX.
We are also seeing a growing demand for our products, both in the US and internationally. In the first full year of availability, we sold more than 50 of our TxCell scanning laser delivery systems. TxCell is a device capable of high-speed laser delivery. Its second version, launched at the end of 2013, addresses an additional market segment while incorporating significant performance enhancements at a reduced manufacturing cost. A key benefit of TxCell is that it facilitates the adoption of our proprietary MicroPulse technology, a disruptive technology used to treat visually disabling ophthalmology conditions such as diabetic macular edema or DME.
By using TxCell, a physician can lay down a blanket of non-tissue damaging laser energy. Repetitive micro pulses combine to produce therapeutic effects in a nondisruptive manner, stimulating the patient's ability to up regulate beneficial proteins, thereby promoting the reduction of the edema and improve visual sensitivity. This structural change is believed to be responsible for the long-term, durable nature of the therapy and the long-term durability proves as economic benefits.
MicroPulse is a unique therapy and it plays an important role in our future. We believe it is a major advance. Over the past year, we have made a concerted effort to educate patients and healthcare payers on its benefits. We are seeing those efforts pay off in terms of general interest in the marketplace at conferences and in sales. MicroPulse is building a reputation as an extremely safe and effective procedure providing durable outcomes at a reduced cost compared to alternative drug therapies.
Let me expand on the idea of value-based medicine since it is an important concept for IRIDEX. Everywhere in the world where there are rapidly growing numbers of diabetic patients, including developing countries like Brazil and India and parts of Europe and Asia, it is becoming clear that repeated drug treatments for diabetic macular edema, or DME, are too expensive and not logistically possible given the millions of patients who seek treatment via injections every six to eight weeks. This is a global issue and part of the developing concept entitled value-based medicine.
MicroPulse, with its single treatment efficacy and the positive long-term durable outcomes represents a major step in the direction of value-based medicine for the rapidly growing global problem of DME. Our products offer a more durable and more cost-effective alternative to the literally millions of people around the world who need a new answer for the diabetic-related ophthalmology conditions. This is an enormous opportunity for us, and we believe we are commercially and operationally prepared to take advantage of it. With that, I will turn the call over to Jim to discuss the financials in more depth. Jim?
Jim Mackaness - CFO and COO
Thanks, Will. As we noted in our press release, and in Will's comments, we had a record quarter in Q4 as revenues reached $10.6 million, up 15% from Q4 2012 revenues of $9.2 million, and up 11% sequentially from Q3, 2013 where revenues were $9.5 million. System sales in Q4 2013 were $6.0 million, up from $5.0 million in Q4 2012, with significant increases in systems sales both domestically and internationally. On a sequential basis, systems sales were up from $4.7 million reported in Q3 2013, similarly driven by both domestic and international sales.
The successful launch of our TxCell device has been a key contributor to this growth as it has significantly increased the ASP's of our system sales, and we continue to see increased unit sales of our MicroPulse-enabled lasers. And again, we are seeing good sales momentum as we enter the beginning of 2014.
Recurring revenues increased to $4.5 million in Q4, 2013, compared to Q4, 2012 recurring revenues of $4.2 million, a 9% increase. And we are down $0.2 million sequentially from Q3 2013. The increase in recurring revenues over last year was primarily a result of the contribution of our independent US sales channel. And the dip from Q3 was the result of timing some orders from Alcon, a distribution partner for one of our (inaudible) products.
Even with this growth, as a result of the significant increase in systems sales previously mentioned, recurring revenues dropped to 43% of the aggregate revenues in this year's fourth quarter, a reduction from 45% reported in Q4 2012 and a reduction from 50% in Q3 2013.
You can see the impact to the change in product mix from recurring sales to system sales in our gross margin performance, notably from Q3 2013 to Q4 2013. Gross margins for Q3 2013 were 49.6%, with systems sales comprising 49% of total revenues. Gross margins for Q4 2013 were 48.6%, with system sales comprising 57% total revenues. Compared to the fourth quarter of 2012, gross margin improved from 47.0% to 48.6%, which we view very positively because we achieved this improvement through overhead efficiencies and cost reduction, and these improvements outweighed the product mix shift from 54% system sales last year Q4 to 57% system sales this year Q4.
These improvements are a good start, and we have additional projects underway to improve our gross margins. The recent launch of our second version of TxCell has a reduced cost base, and a major project for 2014 is the cost reduction program for the IQ platform that supports MicroPulse-enabled lasers. Furthermore, we continue to see positive results in improved pricing leverage with the growing adoption of MicroPulse. These efforts, together with our consumable product development plans, are all part of our strategy to work our way up to our longer-term goal of 55% gross margin.
Operating expenses for Q4 2013 were $4.6 million, up from $4.0 million in Q4 2012. The year-over-year growth is due to additional selling expenses associated with the independent US sales channel brought on in Q2 of 2013; and increases in G&A expenses due to the enactment of the medical device tax; and increased compensation expenses, including profit sharing and bonus accruals.
Operating expenses for Q3 2013 were $4.1 million. The sequential growth in expenses were driven by increased selling and marketing expenses. AAO is our biggest tradeshow, which occurs in our fourth quarter, and increased revenues for both the quarter and year drove increased regular and bonus commission expense.
Operating income for Q4 2013 was $0.6 million, up from $0.3 million in last year's fourth quarter. We did record $0.2 million non-cash other expense in the quarter. This was a result of increasing the contingent earn-out liability on our balance sheet as the outlook for revenues generated for certain acquired products improved. Excluding this item, our earnings per share on a diluted basis would improve by $0.02 for the quarter. Including this expense, as we do in our P&L, our net income from continued operations for the quarter were $0.4 million, or $0.04 per diluted share, compared to $0.3 million, or $0.03 per diluted share, for Q4 2012.
Our full-year results help provide a broader illustration of the progress we have made in 2013. Revenues for the full year 2013 was $38.3 million, up 13% over 2012. Gross margins improved from 48.3% to 48.6%, a small uptick, but given the change in product mix I referenced earlier, a good result.
Operating expenses decreased from $17.2 million to $16.0 million, and operating income was $2.6 million compared to an operating loss at $0.9 million. Net income from continuing operations for 2013 was $2.2 million, or $0.22 per diluted share, compared to a net loss of $0.2 million for 2012, or a loss of $0.02 per share.
Looking to the first quarter of 2014, we are projecting revenues between $9.8 million and $10.1 million, representing growth of between 9% and 13% over the prior year period. Gross margin is anticipated to come in between 48% and 50%. Operating expenses between $4.3 million and $4.5 million, and the Company anticipates generating operating income.
We did have some activity in the stock repurchase program during the fourth quarter. We bought approximately 38,000 shares at an average price of $6.03 during the quarter. And today the Board approved extending the plan through February 2050. And currently, we have 2.6 million available for stock repurchases. And with that, I will turn the call back over to Will. Will?
Will Moore - Chairman and Interim President and CEO
Thank you, Jim. We accomplished our goals for 2013 and are extremely excited about 2014 and beyond. We believe our MicroPulse solution for DME generated momentum for our business in 2013, and the momentum around DME will continue to accelerate in 2014.
I need to highlight the application of our proprietary MicroPulse technology is not limited to DME. It also has applications in glaucoma. During 2013, we started the process of promoting the IQ 532 MicroPulse laser for MLT procedures. A process that improves fluid draining, thus reducing ILP.
In 2014, we will focus on making further inroads in the therapeutic treatment of glaucoma. The IQ 532, with its combination treatment for DME and glaucoma is very appealing to the comprehensive ophthalmologist, who represents a new market opportunity for us.
In addition, we are repositioning our G-Probe for earlier stage glaucoma treatments, and towards the end of this year, we expect to introduce an additional bundle of single-use glaucoma products that are captive to a new MicroPulse laser platform, which if successful will position us for growth in the procedural side of our business model.
By the end of 2014, we expect IRIDEX will be known for its proprietary new MicroPulse treatment providing solutions for two major disease states, DME and glaucoma, with growing capital and recurring revenue streams. I would like to thank our customers, our partners, and all IRIDEX employees for a successful 2013 and look forward to continuing that success in 2014. With that, operator, I would like to turn the call -- open the call for questions.

(Operator Instructions) Larry Haimovitch, HMTC.
Larry Haimovitch - Analyst
Congrats on a nice quarter and a very solid year. I apologize if you went over this during your prepared remarks. I had two other conference calls, and I couldn't catch your whole call. So if I am covering ground that has already been covered, we can talk off-line. I was going to ask you, though, I know you were overseas. You were in India for a while talking to some potential customers and doctors, et cetera. Just wondering what your sense of opportunity is now that you have had a very fresh look at it in some of these countries were we all know that the possibility of monthly or many injections per year is really a difficult financial burden. And a laser for DME -- laser treatment for DME makes so much more sense. So, I would love to hear your thoughts on that.
Will Moore - Chairman and Interim President and CEO
Well, I did spend about 10 days in India at a number of conferences and going to different teaching hospitals and meeting with the chairman of departments. It is pretty clear, in their mind, the current method of treatment, using continuous wave lasers that photo coagulate the spots of leakage is not the long-term answer. They also are very clear that injections are not the long-term answer, but that is not because the outcome is not good. It is because the economic impact on society is too large.
If you just think about the number of doctors versus the number of patients, the idea of coming back every six to eight weeks is just not possible. And the financial burden to the individual patient and their family is enormous. So we will be -- I, hopefully, will be announcing a couple of studies in the near future from a couple of prestigious and institutions there, looking at specifically the problem in India to reduce the cost to society while improving the long-term durability or outcomes to the patient in and around DME. Because diabetes is just a massive problem in India. So, I think the opportunity is quite large.
Larry Haimovitch - Analyst
So the clinical trials would be to show the effectiveness of a mixture of laser treatment along with injections or maybe injections versus laser treatment. What do you think that trial might look like if you were to start a trial in India?
Will Moore - Chairman and Interim President and CEO
I will know more in a week, but a couple of the doctors are meeting this weekend. But the issue is not really -- their viewpoint is, the durable outcomes from MicroPulse and the durable outcomes for injections are comparable. The issues have to do with logistics and cost. And so what they are really looking at is, if, in fact, that is a true statement, then it becomes an actuarial decision, and there is what the recommendations will be to society is to go to something like the MicroPulse. I don't think we're going to be doing a lot of absolute measurements for the size, the reduction of the edema. I think we are looking more from the standpoint -- there is enough studies out there to show that the edema is reduced by MicroPulse, and the edema is reduced by drug. It is really what happens after six months, a year.
Larry Haimovitch - Analyst
Kind of a cost -- sort of a cost to quality of life, societal cost kind of a thing as opposed to a clinical trial comparing one therapy to another.
Will Moore - Chairman and Interim President and CEO
Correct. I think what we're seeing in the US as well, and we use this term value-based, it's really -- there is not enough financial or human capital to treat some of these large diseases that are out there. What is the best way to do it? And their interest is clear, that their viewpoint is drugs do work, but they are just way too expensive and the logistics are impossible to deal with in India.
Larry Haimovitch - Analyst
Yes. I have a couple of other questions, but I don't want to hog the stage here. If there are any other questions in queue, I will jump back in queue.
Will Moore - Chairman and Interim President and CEO
All right. Thank you, Larry.
Operator
Sam Bergman, Bayberry Asset Management.
Sam Bergman - Analyst
Very nice ending to the year and holding tremendous promise for 2014. I got a couple of questions for you on the TxCell scanning system. You, I assume, saw some acceleration in the MicroPulse sales from that additional product in the fourth quarter. Are you seeing the same in the first quarter with that? And what is your expectations for 2014 with the MicroPulse product with this new edition?
Will Moore - Chairman and Interim President and CEO
Well, I am going to answer part of that question. The TxCell system, in combination with MicroPulse, makes the entire procedure that much better. If you think about what we do with MicroPulse, it presents itself on the eye and leaves no damage. There is no visible evidence that it has even been there. When you have the TxCell, you look at the eye and you put these confluent spots -- you basically paint it, lay the blanket over, whatever term you want, over the entire area, and now you know what you have been treating. So the two of them together really promote the ability to do MicroPulse faster, easier, and, as Jim said in his comments, it raises the price for the MicroPulse and the total sales system, but it also increases the value of the laser system itself.
Now, to answer your other questions, I am just going to say that we believe we have got good momentum going forward, and I am not going to put out a number as to how many textiles TxCell's we are going to sell, but I think we are comfortable saying that the number we sold in the last part of the year, and with the new one -- the new reduced costs and faster, will do just fine.
Sam Bergman - Analyst
And the other question I wanted to ask is in regard to the glaucoma products. Are there any FDA approvals needed for any of these products in 2014?
Will Moore - Chairman and Interim President and CEO
Well, there is FDA approval on all products that we manufacture. I think on an earlier call we talked about these are not scientific projects. You have heard me talk in the past and Jim talk in the past about all the little nuggets that Ted and his research group left in the war chest. These are straightforward engineering projects. They will be 510(k)'s, and they will be approved projects at this point in time. We have got product; we have got demo product. And Paul will be filing with the FDA in appropriate time; it is about a 90-day window that it takes for 510(k).
Sam Bergman - Analyst
Do you have a timeline for these products so that you can share with us?
Will Moore - Chairman and Interim President and CEO
We said we will be out by the AAO.
Sam Bergman - Analyst
Okay. Thank you.
Operator
Jason Stankowski, Clayton.
Jason Stankowski - Analyst
Also congratulate you on your hard work and a good quarter as well as the end of the year. The question I guess I have asked at each call is sort of trying to get a sense of a little bit of the inflection point. I know it is not all going to come in one quarter, but is there anything anecdotal to how many -- I know we shut off shipping lasers with MicroPulse activated and have started to charge over the last year or so -- charge for that additional benefit in the lasers. And I am just curious if you are seeing in the numbers an acceleration of people buying the lasers and/or people coming over the transom or through the Internet that are asking for the MicroPulse feature, sort of independent of us out there trying to sell it. Is the buzz starting to percolate a little bit? And, if so, what gives you confidence that that is happening?
Will Moore - Chairman and Interim President and CEO
Okay. So that was a fairly long question with multiple components. I'm going to try to answer correctly. The short answer is, we are getting calls from doctors and our salespeople are going and selling products. There are some that they haven't talked to before on a regular basis. Those are coming from Internet. They are coming from trade shows. They are coming from -- we sold one to Tufts University not long ago, and pretty soon you get alumni from Tufts that are out elsewhere that are calling and saying, I want to do what Elias Reichel is doing. So we get that.
I think the -- we have used the term tipping point and, to me, what we are doing -- what we are seeing now is an acceleration of our product acceptance, as Jim defined, it is running 10% to 15%. To me, that is not the tipping point yet. I think you will see an accelerant even greater than that when we reach that point. And when I look for a few anecdotal type things that you mentioned, if I looked on the Internet and I typed in DME, the day I see MicroPulse, that is a good signal the tipping point is there.
So it is still got to that point where it is widely accepted other than the fact, I can say, it is widely talked about. Wherever I go, I mean, on the trip to India, people were talking about it. I was in Germany before I went there. They were talking about it. They are not buying it yet, with purchase orders, but they are discussing it amongst themselves. And I think what we have said and way we are positioning it is the right way to go. We do no harm. We provide a mechanism that allows the patient's own body mechanisms to treat itself, and the durability of that treatment is so much better than anything else on the market. That is the message. And I think it is resonating, and I think it will continue to resonate in 2014 and beyond.
Jason Stankowski - Analyst
Okay. And I guess just one other thing. We were, I assume, at Hawaiian Eye here in -- was that in January?
Will Moore - Chairman and Interim President and CEO
Yes.
Jason Stankowski - Analyst
And, just curious if anything came out of that. Is that the more comprehensive docs and I know that we are looking for some signs that they are entering kind of our purchasing universe as well. I'm just curious if -- you had mentioned from a couple of the European shows last year that you really thought the conversation was getting elevated. I'm curious if there is any feedback from that show that you can share with us, positive or otherwise.
Jim Mackaness - CFO and COO
Yes. This is Jim. I will just pass on some comments that Tim mentioned, who is there was, who is our VP of marketing in US sales. So yes, continue to see good traction from the comprehensive guys. And I think probably, Jason, something you should not on your calendar is actually coming forward in, I think it is, April of this year. We're going to be doing -- hosting a live luncheon at the cataract -- Annual Society of Cataract and Refractive Surgeons, which is predominantly a meeting that a lot of the comprehensives attend. So in April, we will actually be hosting one of those large luncheons where we are looking to get maybe north of 300 to 400 docs in the audience who would predominantly, again, be comprehensive in nature. And we will be looking to really message, as Will had indicated, the -- some of the crossover ability of the IQ 532 to treat glaucoma, as well as retinal conditions, to that market. So, I think we continue to focus on it. We like the early signs, and we are starting to put some aggressive marketing to penetrate further.
Jason Stankowski - Analyst
Great. Thanks a lot, guys. Appreciate it.
Operator
Joe Munda, Sidoti & Company.
Joe Munda - Analyst
In your prepared remarks, you emphasized the cost benefit of the lasers versus the drugs, in particularly the brick nations. I was wondering, can you give us some sense of what the cost differential would be? I know you have highlighted some of those points in your slides, but I was wondering if you could give us a little bit more detail.
Jim Mackaness - CFO and COO
There is -- and I am pulling this from memory, but just to try and help sort of give you a crystal sort of response. There is a metric out there of the cost-of-life investment, and the numbers that we have heard referenced for the drugs can be as much as $30,000 on an annual basis per patient. And the equivalent can be $3000 for the patient on an annual basis using a laser.
Joe Munda - Analyst
Okay. That's very helpful. And then, as far as a follow-up question is concerned, what is -- I am a little confused. The second iteration of TxCell, what is so different from the first version, as well as why is it so much cheaper on the cost side?
Jim Mackaness - CFO and COO
Well, so the first version of TxCell, these are delivery devices that hook onto a slit lamp that the ophthalmologist owns. So the first version was one flavor, which would be a Zeiss flavor. And typically, our rough, back of the envelope says that that is about 40% of the market. So we knew that. Wanted to get something into the market, and because we wanted to get something into the market relatively quickly, we did first round engineering efforts, if you like, to get the product out, fully knowing that we would have to come out with a second version. The second version is Haag-Streit and Zeiss compatible. So it allows us to sell one product into both, so now we have got the additional 60% market opportunity, which is Haag-Streit slit lamp. So now you have got one product that effectively installs to both most common styles of slit lamp. And we also took the opportunity to take early customer feedback on a couple of the features, most notably speed. We did improve the speed of scanning. And we also took the opportunity to cost engineer out some of the [better] materials. So that was the purpose of TxCell 2.
Joe Munda - Analyst
Okay. And then, I guess, one other. You touched on glaucoma opportunity, but specifically for what you guys are targeting, what is that market opportunity, specifically to your products?
Will Moore - Chairman and Interim President and CEO
Well, Joe, I think the way we will talk about the opportunity at this point in time is Jim and I look at markets -- overall market that we can address. And the first one was a diabetic market, and it is estimated now that we are talking 450 million people within another 10 years or so with the disease. So the magnitude of the problem is pretty big. The next major area in our space have to do with the macro trends of the aging population. And post-65 is the fastest-growing demographics (inaudible) in that area, and those people are the ones that come down with glaucoma.
The glaucoma piece has multiple facets to it. And from early stage to late stage, and it is not curable. All you can do is slow it down. We started out by doing the late stage with the G-Probe, and we are just -- we are migrating up to earlier and earlier stages. And we will, as we get closer and closer to the release, we will provide more information as to what we think the exact market opportunity is for us. And I think you can look at it from -- right now, look at it in the macro trend, we are attacking a population that is aging, that has glaucoma, that there is no solution. So it is a pretty serious issue.
And the only treatments are drops, which help, but it gets difficult when you are having to take two or three drops and you are 70 years or 80 years of age; surgical intervention; SLT lasers; ALT lasers; shots. There is just a variety of treatment modalities. And we will be moving into that with the system that has a laser that reduces a treatment for four or five differing areas of glaucoma. And that is about as much as I will say.
Joe Munda - Analyst
Okay. Thank you.
Operator
Thank you. And there are no further questions. At this time, I would like to turn the call back to management for any closing remarks.
