GSLS to Collaborate with International Forum for Scleral Lens Research
PentaVision LLC, parent company of the Global Specialty Lens Symposium (GSLS), announces that the Global Forum for Specialty Lens Research (GFSLR), formerly known as the International Forum for Scleral Lens Research (IFSLR), will take place at the conclusion of the 2019 GSLS on Jan. 27 at The Tropicana Hotel in Las Vegas.
Dr. Jan Bergmanson, who began the IFSLR two years ago, will continue in his role as director chair of the GFSLR, working in close collaboration with GSLS Education Committee Chair, Dr. Jason Nichols. The mission of the meeting—to advance the discipline of scleral contact lens prescribing through the coordinated efforts of evidenced-based research and clinical practice—will be broadened to include all specialty/custom contact lenses.
The GFSLR is an open meeting that practitioners and laboratories interested in the latest developments and research attend to exchange ideas. The meeting is dedicated exclusively to research-supported presentations by some of the best-known experts working in the specialty lens field today.
The IFSLR is being rebranded as the Global Forum for Specialty Lens Research (GFSLR) to reflect both the expansion of its content scope and its association with the GSLS.
Johnson & Johnson Vision Introduces AI-Powered Virtual Assistant for Contact Lenses
Johnson & Johnson Vision introduced Andy, a virtual assistant chatbot powered by artificial intelligence (AI). Andy can be found by connecting with Acuvue on the Facebook Messenger app. Andy will allow users to obtain answers to their contact lens-related questions at any time of the day from the convenience of their computer or mobile device. Like other AI-powered technologies, Andy becomes smarter with each interaction.
With Andy, Johnson & Johnson Vision says it aims to empower those who are considering contact lenses while also helping new wearers who may have questions or challenges with applying, removing, or caring for their new contact lenses. Research shows that these can be barriers, causing some new users to give up. Andy is intended to be a new source of information and support in addition to that provided by eyecare professionals.
To chat with Andy, users can search for “Acuvue” in the Facebook Messenger app, which is free to download from the App Store or Google Play store.

Prevent Blindness Declares May UV Awareness Month
Prevent Blindness has declared May as Ultraviolet (UV) Awareness Month to help educate the public on the dangers that UV exposure may have on vision. UV damage may cause immediate effects, such as a corneal sunburn (photokeratitis). UV damage has been linked to the development of macular degeneration, cataract, pterygium (a growth on the white part of the eye), and cancer.
The risk of sun-related eye problems is higher for people who spend long hours in the sun; have certain retina disorders; had cataract surgery (although some artificial lenses do absorb some UV rays); and are on certain medicines, such as tetracycline, sulfa drugs, birth control pills, diuretics, and tranquilizers that increase the eye’s sensitivity to light.
When purchasing sunglasses, Prevent Blindness recommends that consumers always read labels carefully and only buy sunglasses that clearly state that they block 99% to 100% of UV-A and UV-B rays.
For those participating in outdoor sports activities, Prevent Blindness recommends consulting with an eyecare professional on eye protection that both blocks UV and protects eyes from injury.

Does your ability to use contact lens care starter kits influence your prescribing patterns associated with contact lens care solutions?
Inclusion bubbles typically require modification of the periphery of a contact lens. Sometimes this is not so evident with white light at the slit lamp. The “fluorescein seepage test” is very useful for this. You can see superiorly where areas of fluorescein “seep in” and the corresponding inclusion bubbles in those areas as well. This technique is very useful in peripheral haptic modification.

The Influence of Lens Care Systems on Eyelid Tissue Changes During SiHy Lens Wear
Back in the days of annual replacement contact lenses, practitioners battled against giant papillary conjunctivitis (GPC) on a daily basis. It was quickly realized that these lens materials and care systems played a significant role in the development of GPC and its management. It was also quickly realized that lens deposits (specifically denatured proteins) were a major culprit, that certain lens materials were more “deposit resistant,” and that more frequent lens replacement and more aggressive lens care systems helped in preventing development of GPC. Hydrogen peroxide systems became the go-to lens care regimen in this regard.
With the advent and increased use of frequent replacement lenses (especially single-use daily disposables), the frequency of GPC in the contact lens-wearing population has significantly decreased. However, it is still an important clinical entity that needs to be kept in mind and managed.
A recent study1 was published that compared the effects of a hydrogen peroxide (H2O2)-based lens care solution and a polyhexamethylene biguanide (PHMB) multipurpose solution (MPS) on the eyelids when used with silicone hydrogel (SiHy) contact lenses.
A total of 74 symptomatic wearers of Acuvue Oasys (Johnson & Johnson; senofilcon A; n = 39) or PureVision (Bausch + Lomb [B+L]; balafilcon A; n = 35) contact lenses were randomized 1:1 to either Clear Care Cleaning & Disinfecting Solution (Alcon) or ReNu Fresh multipurpose solution (B+L) (n = 37 each). Assessments of hyperemia, papillae, and lid margin staining of eyelid tissue were evaluated subjectively by a masked investigator at enrollment (with the subjects’ habitual SiHy contact lenses and PHMB-preserved care systems), at dispensing visit (when no lenses were worn), and at the three-month follow up.
Results of the study indicated that there were no differences in eyelid assessments between the two lens care groups at the dispensing visit (p = 0.086 to 0.947). After three months, the papillae response was significantly less marked with H2O2-based solution than with PHMB-based solution (p = 0.017). Lid hyperemia (p < 0.001) and papillae (p = 0.002) were also significantly reduced. Although lid hyperemia was also reduced with PHMB-based solution (p < 0.001), there was no concurrent decrease in papillae response (p = 0.051). No improvements were found in eyelid margin staining either over time or between the two lens care groups. The researchers concluded that in symptomatic contact lens wearers, an H2O2-based lens care solution used with senofilcon A and balafilcon A lenses was better tolerated by eyelid tissues than was a PHMB-based solution, and the H2O2-based lens care solution led to a decrease in clinical markers of eyelid inflammation.
I was not surprised with the results from this study based on my practice experience. For reusable frequent replacement SiHy lenses, a peroxide-based care system was superior compared to an MPS system in terms of lid inflammatory responses including papillary responses. Because the majority of our patients, at least in the United States, still wear reusable contact lenses, we must continue to pay attention to the role that care systems play in patient outcomes.

OCULAR SURFACE UPDATE
Katherine M. Mastrota, MS, OD
What Do You Do for a Living?
It is my practice to ask every patient their occupation. There is so much information to be gleaned about the environment in which a person spends a significant part of their day and so many questions about how these surroundings impact their ocular surface. Consider a recent study of 140 welders reported this month in Contact Lens & Anterior Eye. It investigated tear film secretion and objective and subjective indices of dry eye in these subjects.1
In this cohort, welders with at least five years of experience were compared with controls. A complete evaluation of ocular health was performed for all participants. Schirmer test and tear breakup time (TBUT) were applied for objective evaluation, and the Ocular Surface Disease Index (OSDI) was used for subjective assessment of the tear film status. It is important to note that welders are prone to ocular injuries and exposure to ultraviolet light. This study cohort consisted of 140 welders (mean age: 46.66 ± 13.01 years) and 172 controls (mean age: 45.05 ± 12.61 years).
The results demonstrated that the values of the Schirmer test and TBUT were significantly worse in welders than in controls. OSDI revealed that 81.2% of welders had degrees of dry eye that were considered severe in 46.2% of the welders, while 35.5% of controls had dry eye.
The authors conclude that the percentage of dry eye and tear problems is higher in welders than in non-welders. In addition, most of the affected welders have severe dry eye, and it seems that the main reason for dry eye in welders is aqueous deficiency.
Ask the occupation question—the answer may give you an important clinical clue.

Comparison of the Lubricity and Surface Roughness of Five Cosmetic Contact Lenses
Cosmetic contact lenses are increasingly popular because of their eye-enhancing cosmetic benefits. The pigment particles used in these lenses can impact lens surface characteristics. The purpose of this study was to examine the surface characteristics and the differences between the clear and the pigmented regions among five limbal ring design lenses.
Scanning electron microscopy was used to determine the location and depth of the pigment particles from the lens surface. The coefficient of friction (CoF) was determined with a Basalt-MUST microtribometer (Tetra) at clear and pigmented regions on either the front or the back surface. Atomic force microscopy was used to determine the surface roughness of each lens in root-mean-square (RMS) units at clear and pigmented regions. A linear mixed model for repeated measures was used for the analysis of the CoF and RMS roughness to compare all lenses.
Four lens types had pigments exposed on the surface, and one lens type had pigment fully enclosed. The CoF difference between clear and pigmented regions was similar and not statistically significant (P = 0.01) for the lens type with pigments enclosed, whereas the CoF difference for the other four lens types showed statistically significant difference (P < 0.0001).
Of the lenses tested, cosmetic contact lenses with pigments enclosed in the lens matrix provided a more consistent surface between clear and pigmented regions compared with lenses that had exposed pigments.
