International Prescribing Data Requested
Last week, 1,000 U.S.-based Contact Lens Spectrum (CLS) readers were sent the annual International Survey of Contact Lens Prescribing. Please check your mailboxes and inboxes to see whether you were one of the lucky few chosen to participate in this important research. Data collected from U.S. prescribers as well as data collected from more than 30 other global contact lens markets are tabulated and analyzed by Eurolens Research to create a snapshot of current international contact lens prescribing trends. Your participation in this survey is vital to create an accurate picture of current U.S. prescribing trends. If you received the survey but do not fit contact lenses, please pass it on to a colleague who does. Survey forms must be returned by Aug. 15, 2019. Results will publish in the January 2020 CLS article “International Contact Lens Prescribing in 2019.”

Wöhlk Contactlinsen GmbH has formed a capital alliance with Japanese contact lens manufacturer, SEED Co. Ltd., which acquired a 40% stake in Wöhlk. According to Wöhlk, this international collaboration strengthens its position in the international market and, at the same time, expands its portfolio; while Wöhlk is an expert in individual contact lenses, SEED Contact Lens focuses on the production of daily disposable and two-week lenses.
Maryland Expands Scope of Practice for Optometrists
Maryland Gov. Larry Hogan has signed into law a measure expanding optometrists’ scope of practice. Signed into law April 30, the bipartisan legislation (House Bill 471/ Senate Bill 447) amends the state’s optometric scope of practice to repeal certain provisions of law that required a therapeutically certified optometrist to refer certain patients to an ophthalmologist. It also authorizes prescribing authority for topical agents and oral pharmaceuticals (with some exceptions) for the prevention, management, or treatment of conditions and diseases of the eye and ocular adnexa and expands procedures and management of certain patients. The measure will take effect in March 2020.
Optometry Student Challenge Announced
ABB Optical Group, in partnership with Paragon Vision Sciences, announced that it is accepting abstract submissions for the fifth annual Optometry Student Challenge.
The Optometry Student Challenge will award travel grants of $1,500 each to three third or fourth-year students to attend the 2020 Global Specialty Lens Symposium, held on Jan. 22 to 25, 2020 in Las Vegas, and present a scientific poster on a topic related to contact lenses. Last year, more than 90 optometry students submitted contact lens-related abstracts focused on study projects or student-based case histories.
Students who are interested in participating must register by Aug. 9, 2019. Registered students must then submit an abstract on their proposed poster topic by Oct. 11, 2019. Abstracts must focus on study projects or student-based case histories related to contact lenses. Abstracts will be judged in two categories: case study report and research.
Five finalists will be selected and notified by Oct. 25, 2019. The finalists will then be required to convert their abstracts into scientific posters for further judging. The posters must be submitted in digital, PDF format to ABB Optical Group no later than Nov. 15, 2019. Results will be communicated with the winners and runners-up by Nov. 27, 2019.

SPECIALTY LENS SPACE
Karen DeLoss, OD
Pick a Lens, Any Lens?
Specialty lens fitting for keratoconus has its advantages and disadvantages and can range from too many options to meeting patient expectations to high cost. While scleral lenses have taken off in popularity, it is still beneficial to have a firm foundation for fitting GP lenses. It is also beneficial to revisit fitting guides and even refer to old notes and books to look for insights and tidbits. It can sometimes be overwhelming if you have a large library of specialty lenses as well.
It has been proven that GP lenses can improve visual function for many corneal conditions.1 The goals of eyecare practitioners are always to improve vision, minimize corneal trauma, and provide all-day comfort for their patients. Fitting GP lenses requires patience and a bit of background.
I use the mid-K strategy for selecting my initial lens. While this may not always be effective, it’s a starting point. From there, I can make adjustments to go steeper or flatter with my next choice. There are some people who would start slightly steeper than average keratometry, which is why GP fitting is an art as much as it is a science. However, the best advice I was ever given is: If you don’t know where to start, pick up a trial lens set and pick the lens in the middle. That way, if it doesn’t fit during a diagnostic fit, you have eliminated half of the fitting set.

Toric Daily Disposable Lenses Are Here
The day has arrived. The excitement is in the air, and there is no stopping us now. Daily disposable toric lenses are here, and more than 95%* of all toric patients can be fit into the modality that is best of them. Sure, there are some oblique cylinder patients who may have fewer daily options. Additionally, practitioners still struggle with patients who have more than –2.50D cylinder. However, the vast majority are there.
It’s important to realize that toric patients tend to have more challenges with lens wear. Stability is a major problem for many of them, and because they wear frequent replacement lenses (even compliantly), many of them will find that their vision (and comfort) gets worse throughout the day as the lens gets older. If practitioners can move them into a daily disposable lens, they will be able to have a fresh lens daily that will have fewer deposits and a smoother surface to aid in stability.
May I implore you on behalf of us toric patients, find two daily disposable fitting sets that you can fall in love with, and introduce them to your patients. They will fall in love too.

Bifocal & Atropine in Myopia (BAM) Study: Baseline Data and Methods
This study aims to determine whether combining 0.01% atropine and +2.50D add center-distance soft bifocal contact lenses (SBCLs) slows myopia progression more than SBCLs alone do. The study looked at characteristics at baseline and the short-term effects of this combination treatment on visual acuity (VA) and vision-related outcomes.
Subjects from the BAM study who met the baseline eligibility criteria were dispensed the combination treatment for two weeks to determine final eligibility. Outcome measures included VA at near and distance (Bailey-Lovie logMAR charts), near phoria (modified Thorington test card), accommodative lag (Grand Seiko WAM-5500), and pupil size (NeurOptics VIP-200 Pupillometer). Compliance was monitored using surveys. Two subgroups in the Bifocal Lenses In Nearsighted Kids (BLINK) study-single-vision contact lens wearers and those who wore +2.50D add SBCLs—will serve as the age-matched historical controls for BAM study.
Forty-nine BAM subjects (9.6 years ± 1.4 years) were enrolled; mean spherical equivalent cycloplegic autorefraction was –2.33D ± 1.03D. After two weeks of treatment, the best-corrected low-contrast (10% Michelson value) distance VA was reduced (pre-treatment, +0.09 ± 0.07; post-treatment, +0.16 ± 0.08; P < 0.0001), but the high-contrast VA at near or distance was unaffected. Near phoria increased by approximately two in the exo-direction (P = 0.01), but the accommodative lag was unchanged. The pupil size was not significantly different between pre- and post-treatment of either the photopic or mesopic condition. Surveys indicated that the subjects wore SBCLs 77% ± 22% of waking hours and used atropine 6.4 days ± 0.7 days per week.
The researchers concluded that two weeks of combination treatment reduced low-contrast distance VA and increased near exophoria slightly, but the subjects were compliant and tolerated the treatment well.
