As we have seen, there is no doubt that the daily disposable category continues to grow, both in the United States (approximately one-third of soft lens fits) and also in many international markets.1,2 We are seeing many design expansions in the daily disposable category helping to fuel this growth.
What remains a challenge in many markets is perhaps a perceived cost versus benefit scenario. Specifically, the daily disposable category is perceived to be more costly, while there can be a patient perception (or sometimes a reality) that the benefits are not there (“They were not as convenient as I thought.” Or, “They did not improve my discomfort at the end of the day.”).
However, as the growth data for this category suggest, it seems as though new technologies in daily disposables are helping us overcome this hurdle.

Through sponsorship from CooperVision, three IACLE Contact Lens Educator of the Year Awards will be presented, one from each of IACLE’s three global regions. The annual Travel Award is funded by IACLE. All four awards are supported by the BCLA. The 2017 winners are:
* IACLE Americas Contact Lens Educator of the Year – Professor Jan Bergmanson, University of Houston, Texas * IACLE Asia Pacific Contact Lens Educator of the Year – Professor Koon-Ja Lee, Eulji University, Seongnam, Korea * IACLE Europe / Africa – Middle EastContact Lens Educator of the Year – Dr. Yazan Gammoh, Amman Ahliyah University, Amman, Jordan * IACLE Travel Award – Professor Martha Lucila Márquez García, Santo Tomás University, Bucaramanga, Colombia
The IACLE Awards will be presented in the main auditorium at the BCLA Conference, on June 11. Recipients will also have the opportunity to attend the Education Day organized by IACLE and BUCCLE.
Imprimis Pharmaceuticals Acquires Exclusive License to Klarity
Imprimis Pharmaceuticals, Inc. has entered into an licensing agreement for the exclusive worldwide rights to Klarity, an ophthalmic topical solution and gel technology for patients who have dry eye disease (DED).
Klarity is designed to protect and rehabilitate the ocular surface following ophthalmic surgery, contact lens wear, or in patients who have moderate to severe DED, such as the development of epithelial and stromal corneal edema, the presence of increased oxidation agents and free radicals, cellular damage and death, and a significantly irritated eye. The Klarity formulation is preservative-free and can be formulated to any viscosity, ranging from a topical drop or gel to a dispersive viscosurgical device. The active ingredients include chondroitin sulfate, a cell membrane stabilizer, deturgescent agent, free radical scavenger, and lubricant.
If you haven’t voted yet in this month’s poll…
What percentage of your contact lens dropouts do so because of contact lens discomfort?
This patient was born with a limbal dermoid in her left eye that was promptly removed as a young child. Years later, she developed a descmetocele. She then underwent a corneal patch graft procedure resulting in significant irregular astigmatism and dryness. To manage these symptoms, she was fit with a large-diameter scleral lens, improving both her visual acuity and ocular surface comfort.

CARE SOLUTION CORNER
Andrew D. Pucker, OD, PhD
Every Problem Has an Expiration Date
Early in my career, I walked into Ohio State’s Contact Lens Clinic and noticed that my service chief was destroying a large pile of contact lenses with a knife. I was confused at first; however, he quickly explained to me that he was discarding all of the expired trial contact lenses in the clinic. While this is an excellent practice that we should all follow, expired ophthalmic products are nevertheless frequently found in the patient care setting.
A seminal study from Wessels and colleagues highlights this point.1 Specifically, the authors examined 1,485 opened medication bottles that were collected from 18 different ophthalmology clinics.1 The study found that 19.7% of the analyzed bottles were expired and that the expired bottles were, on average, 15.1 months past their expiration date. Furthermore, only two of the sites tested were expired bottle-free.
Manufactured products like soft contact lenses, contact lens care solutions, ocular medications, and diagnostic drops generally have an expiration date because product packaging and the products themselves can break down, which can occasionally lead to microbial contamination or even the production of harmful chemicals.1 Consequently, I urge you to get into the habit of doing some regular spring cleaning to rid your office of expired products that could potentially harm your patients. I also urge you to educate your patients about why they should do the same within their own homes.

The Low Hanging Fruit
As clinicians, we want to help the people who need our help. As business people, we want to help the least number of people we can while getting the most amount of money. Is this a conflict?
Most practitioners have a system in place to recall all of the patients they saw the year before. For those of you who do recall patients, some of you may just leave it to automate and hope for the best.
If you do not have this, you have one of two problems: 1) You do not care about your growth and are happy and complacent with where you are—I can’t help you. 2) You are so busy that you cannot imagine seeing more patients—you need a lot of help. If you are in the second group, there are things that you can do that can be outlined in much better detail in another posting, but hiring an associate and adding an exam room are two simple ways to expand.
My suggestion is for you to work to use your automation system to bring in the patients whom you want to see rather than the patients who just happen to come in. What I mean is—target the specialty keratoconus, orthokeratology, daily disposable, high-spending glasses wearers, and others who generate more money. These patients like to spend money with you because they see that you bring them a greater value. They do not see you as a “me too” practice, but rather someone who fits in with their objectives for eye care and life.
If we can see those patients who want to see us, we can make a better impact on them because they have better compliance, trust the things we say, and have better outcomes. Seeing these patients also generates more revenue for the office, because the patients take us up on our recommendations, do not “argue” over cost as much, and willingly take our recommendations.
You can have the best of both worlds; recall who you want to see.
Effects of Myopic Orthokeratology on Visual Performance and Optical Quality
The object of this study was to analyze the changes in visual performance and optical quality after orthokeratology (ortho-k) treatment and its correlation with the magnitude of lens decentration and the diameter of the treatment zone (TxZ).
A prospective study was conducted in 27 eyes of 27 patients wearing ortho-k contact lenses. Area under log contrast sensitivity function (AULCSF), modulation transfer function cutoff values (MTFcutoff), Strehl ratio (SR), and objective scattering index (OSI) were measured and compared before and one month after ortho-k lens treatment. Refractive sphere, astigmatism, and diameter and decentration of TxZ were tested against the change in AULCSF, MTFcutoff, SR, and OSI after ortho-k treatment in stepwise multiple linear regression models.
The authors found that the objective scattering index significantly increased whereas AULCSF, MTFcutoff, and SR significantly decreased after ortho-k lens wear (all P < 0.001). The mean TxZ diameter was 3.61mm ± 0.26mm, and the mean magnitude of TxZ decentration was 0.60mm ± 0.16mm. The amount of lens decentration significantly correlated with the change in AULCSF and MTFcutoff (P = 0.027 and P = 0.005, respectively). The diameter of TxZ significantly correlated with the change in MTFcutoff and SR (P = 0.005 and P = 0.024, respectively).
The report concluded that visual and optical quality decreases after ortho-k treatment; this can be alleviated by a larger TxZ diameter and less lens decentration.
