As noted in this month’s Quick Poll, 81% of respondents felt as though online channels for contact lens prescriptions or sales have impacted the contact lens portion of their practices. The assumption is that the impact is not a positive one. We would like to hear and share your experiences (or those of your patients) with online channels for contact lens prescriptions.

Onefit Scleral Lenses Have FDA 510(k) Clearance for Treatment of Dry Eye When Manufactured in Optimum Materials
Blanchard Contact Lenses announced that its Onefit family of scleral lenses now has 510(k) clearance from the U.S. Food and Drug Administration for therapeutic applications—including treatment of dry eye—when manufactured in Contamac’s Optimum Extra, Optimum Extreme, and Hexa 100 materials. Contamac announced the 510(k) clearance earlier this month.
Optovue Announces Expanded FDA Clearance of Epithelial Thickness Mapping
Optovue announced an expanded U.S. Food and Drug Administration 510(k) clearance for non-contact, quantitative measurements of the epithelial and stromal layers of the cornea, termed epithelial thickness mapping or ETM. The expanded clearance adds a 9mm ETM scan to the previously available 6mm map, allowing for detection of epithelial irregularities in an area that is about 2.25 times that of the area covered by the 6mm scan.
Optovue says that its new mapping software provides epithelial thickness information in an efficient and simple exam. Traditional epithelial measurements require high-frequency digital ultrasound and saline. In addition, ETM software complements other diagnostic tests by providing information about ocular health that may be clinically valuable prior to topography-guided procedures including laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK), according to the company. ETM was previously cleared on the company’s iVue system in 2017.
BCLA and MCLOSA Announce Joint Meeting

Have online channels for contact lens prescriptions or sales impacted the contact lens portion of your practice?
This image shows a 51-year-old African-American male who had a history of penetrating keratoplasty (PKP) in both eyes for keratoconus. He is aphakic in the right eye and developed steroid response glaucoma in the same eye. He then developed angle closure glaucoma due to vitreous prolapse in the same eye. He now has a tube shunt and is waiting to have a second one placed. His vision with scleral lenses is 20/20 in both eyes, and he could not be happier. We are keeping a close eye on the endothelial cell count and intraocular pressure.

Dry Eye Symptoms and Duration of Contact Lens Wear – Is There a Correlation?
Common thought would have us believe that the longer a contact lens is worn on the eye, the greater the degree of dry eye symptoms in wearers who have dry eye complaints. A recent study was published that analyzed the correlation between the daily lens wear duration and dry eye syndrome.1 This cross-sectional study using consecutive sampling was conducted among students aged between 17 to 23 who wore contact lenses continuously for at least one year and at least five days per week. The symptoms were assessed using Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8). In addition, the subjects were interviewed about their contact lens comfort, eye drops usage, contact lens washing habit, daily circumstances, places to buy contact lenses, and personal experience in wearing contact lenses.
The questionnaire was completed by 53 students, all of whom were female and who wore soft contact lenses. The mean duration of daily wear was 8.19 ± 2.20 hours. The most common symptom experienced was dry eye, and the least common symptom experienced was irritation following removal of lenses. The study used Exact Test as the analysis statistic method. The result was p > 0.05, which means that there is no correlation between daily lens wear duration and dry eye syndrome.
The authors concluded that dry eye syndrome was not correlated with daily lens wear duration but is affected by many factors such as the contact lens, lens care solution, eye drops usage, and environment.
Without question, dry eye symptoms and findings are surely multifactorial. Are practitioners dealing with a true underlying ocular surface disease state, or are symptoms only induced by contact lens wear? A proper ocular surface disease diagnostic analysis should be conducted for all patients who are symptomatic or who show physical signs suggesting ocular surface disease. However, it is important to also perform a complete ocular surface and tear film evaluation for all patients considering contact lenses.

OCULAR SURFACE UPDATE
Katherine M. Mastrota, MS, OD
Maintaining a Good Balance
It is generally accepted that cosmetics and cosmetic procedures can present a challenge to the exquisite homeostasis of the ocular surface.
Cosmetics are manufactured with a myriad of ingredients, including preservatives. In the United States, cosmetic products are regulated post-market. Surveillance programs are one of the U.S. Food and Drug Administration’s (FDA) most important tools for monitoring microbiological safety of cosmetics. "Traditional" cosmetic preservatives—such as parabens and formaldehyde releasers—are controversial chemicals so now, cosmetic manufacturers are substituting "nontraditional" and "natural" preservatives (e.g., botanical extracts).
The FDA conducted a survey of eye-area cosmetics that claimed to be free of traditional preservatives and determined the microbiological loads in tested products.1 The survey explored the association of microbial loads with the physical and chemical characteristics of the cosmetic products and outlined the limits of preservative activity in selected cosmetics.1 In this survey, 93 eye-area cosmetic products that are marketed as "green," "natural," "paraben-free," "preservative-free," or that contained nontraditional preservatives (e.g., botanical extracts) were analyzed for water activity, pH, and microbiological content.
The survey results indicated that 60% of the eye-area cosmetics were free of microbiological growth under test conditions, 32% showed the presence of micro-organisms at low levels, and 8% showed microbiological growth at higher levels. Gram-positive bacteria such as Bacillus and Staphylococcus were the dominant genera identified in these cosmetic products, whereas Gram-negative species were relatively uncommon.
The survey also found a positive association between lower-water-activity cosmetics and the presence of micro-organisms in the products. The most represented micro-organisms in the survey were Bacillus, suggesting that the natural raw materials are the likely source of observed microbial loads.
It is doubtful that low levels of bacteria in an eye cosmetic would be harmful to an immunologically competent individual; however, it is yet an added concern to the potential ocular surface and tear film compromises that eye cosmetics may incite or aggravate.

Bacterial Coaggregation and Cohesion Among Isolates from Contact Lens Cases
The purpose of this study was to examine cohesion, coaggregation, and coculture among bacteria commonly isolated from contact lens cases.
This study used two strains each of Staphylococcus epidermidis, Staphylococcus haemolyticus, Micrococcus luteus, and Acinetobacter radioresistens that were isolated from contact lens cases of two asymptomatic patients. In the cohesion assay, bacteria were grown, washed, and examined by incubating lens cases that have two different types of bacteria sequentially and assessing the number of adhered cells of each isolate. The ability of isolates to interfere with the growth of other isolates was tested by growing strains in cocultures for 24 hours and determining the numbers of cells of individual strains. For coaggregation, equal proportions of two bacterial suspensions were mixed and allowed to coaggregate for 24 hours. Inhibition of coaggregation was tested by the addition of lactose (0.06 M) or sucrose (0.06 M) or pronase.
The initial adhesion of M. luteus or A. radioresistens significantly (P < 0.05) enhanced the subsequent adhesion of the staphylococci. The addition of A. radioresistens in liquid media significantly (P < 0.05) enhanced the growth of staphylococci. S. epidermidis or S. haemolyticus coaggregated with M. luteus or A. radioresistens. The degree of coaggregation varied between 30% and 54%. The highest coaggregation (54% ± 5%) was seen between A. radioresistens 22-1 and S. epidermidis 22-1, isolated from the same lens case. Only lactose or sucrose treatment of staphylococci could partly inhibit coaggregation of some pairs.
The authors concluded that coaggregation, cohesion, and growth promotion may facilitate the process of bacterial colonization of contact lens cases.
