A recent Scopus search of “contact lens” within the title, abstract, or keyword of documents associated with Index Medicus yielded 698 articles that met this criteria in 2019 (to date). Over the last several years, that number has been as high as 987 articles. A similar search for another related term, “dry eye,” returned between 708 to 1,159 articles over this same period. Although there have been significant research activities in these spaces, it is important for us to help translate this knowledge into clinical practice.

Bio-Tissue Launches Website to Educate on Solution for Mechanical Dry Eye
Bio-Tissue, Inc. announced the launch of an educational website, www.DiscoverMDE.com, on Mechanical Dry Eye (MDE) also sometimes referred to as conjunctivochalasis (CCh). The website features educational information, videos, testimonials, and other resources for both patients and health care providers.
According to the company, the website will provide important information to patients and their caregivers so that they can learn more about MDE/CCh. It further enables physicians to differentiate MDE/CCh from conventional dry eye and engage their patients in a discussion to provide options to manage this condition.
Novaliq and Jiangsu Hengrui Medicine Announce a Collaboration
Novaliq and Jiangsu Hengrui Medicine, a biopharmaceutical company based in China, closed an exclusive license agreement to develop, manufacture, and commercialize water-free drugs NOV03 and CyclASol for the treatment of dry eye disease (DED) in the People’s Republic of China (including mainland China, Hong Kong, Macau, and Taiwan).
Under the terms of the agreement, Novaliq is eligible to receive an upfront payment of up to $9 million and up to $156 million in milestone payments linked to predefined development, regulatory, and commercialization objectives. In addition, Jiangsu Hengrui Medicine will be obligated to pay Novaliq tiered percentage royalties on net sales of NOV03 and CyclASol in China. Jiangsu Hengrui Medicine secures exclusive rights to develop, manufacture, and commercialize both drugs in China. Jiangsu Hengrui Medicine will be responsible for all development, regulatory, and commercialization activities and related expenses in the territory.
NOV03 (perfluorohexyloctane) is being developed as a treatment for patients who have DED associated with meibomian gland dysfunction and has a novel mode of action that has been confirmed in various studies. CyclASol is an anti-inflammatory investigational drug for patients who have moderate to severe DED that has an inflammatory disease component. CyclASol contains cyclosporine A 0.1% in EyeSol and holds the promise of unfolding cyclosporine A’s full potential on the ocular surface, enabling clinicians to treat more patients successfully, according to the companies.

Corneal Endothelial Bleb Formation in Scleral Lens Wear
Corneal endothelial bleb formation has been reported during contact lens wear and goggle-induced hypoxia or hypercapnia. A recent study looked at whether blebs appear after scleral lens wear and whether their appearance is influenced by lens clearance; it also compared bleb and cell sizes.1
Twenty-one subjects were fit with two similar scleral lenses (SLs) that had different targeted clearances of 200μm and 400μm (the SL200 and SL400, respectively). Each lens was worn unilaterally for 25 minutes, whereas the other eye served as a control. Before and after lens wear, the endothelium was photographed using specular microscopy. The number of blebs and measurements of the areas of cells and blebs were analyzed. Paired t tests compared differences in the areas of cells and blebs. Differences in median bleb number were evaluated using the Wilcoxon test.
Results indicated that after wearing the SL200 and SL400 lenses, nine and 14 subjects had at least one bleb, respectively. The median bleb number after wearing lenses was significantly different (SL200, 0.00; SL400, 1.00; P = 0.02). Bleb and cell areas were significantly different (blebs, 293 ± 28; cells, 370μm ± 32μm; P < 0.0001).
The authors concluded that after 25 minutes of wearing scleral lenses with each of the two targeted clearances, the SL400 induced significantly more blebs than did the SL200. This suggests evidence of reduced oxygen and/or increased carbon dioxide levels under scleral lenses fit with excessive clearance and that blebs may occur more in smaller cells. This study may further suggest that excessive corneal vaulting may result in hypoxic sequelae.

OCULAR SURFACE UPDATE
Katherine Mastrota, MS, OD
The Perfect Eyelash Length
Bionics, or biologically inspired engineering, is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
Recently, a coupled multi-physics model was developed to characterize ocular water evaporation with realistic eyelash structures taken into account.1 From a chemical engineering perspective, the protective function of human eyelashes—in terms of evaporation inhibition—was rationally revealed. Systematic investigations were carried out to demonstrate the effects of different eyelash lengths, orientations, and inlet air directions on water evaporation on the ocular surface.
The results illustrate that, regardless of inlet air directions and eyelash orientations, increasing eyelash length from zero to an optimal length can effectively reduce water evaporation. However, an additional increase in the eyelash length can lead to enhanced evaporation.
For the normal and parallel inlet air directions, the optimal eyelash length is around 15% to 30% of the eye width and can offer approximately 10% to 30% evaporation reduction when compared with the cases without eyelashes. These values are independent of the eyelash orientation.
This study provided valuable data for a greater understanding of the protective function of the eyelashes. With this in mind, consider the negative effects of ultra-long artificial lashes and their impact on increased ocular surface desiccation.

Clinical Findings and Ocular Symptoms Over 1 Year in a Sample of Scleral Lens Wearers.
The purpose of this study was to report the fitting aspects, clinical findings, and symptoms over 12 months of scleral lens (SL) wear. Sixty-nine patients who have irregular corneas due to ectasia or surgical procedures (IC group) or regular corneas that have high ametropia (RC group) completed the 12-month prospective follow-up period. Patients were evaluated at baseline, lens dispensing visit, one month, three months, six months, and 12 months for assessment of comfort, fitting aspects, and slit lamp findings. Comfort was assessed with the Ocular Surface Disease Index (OSDI) questionnaire and the Dry Eye Questionnaire. Slit lamp evaluations comprised on-eye lens fitting (lens alignment and tear reservoir thickness) and anterior ocular surface health after removing the lens (edema, hyperemia, staining, and adverse events).
OSDI scores were significantly reduced after one month of SL wear comparing to baseline (from 47.0 ± 22.7 to 23.9 ± 14.7 in the IC group, P < 0.001; and from 27.0 ± 16.1 to 17.0 ± 13.7, P = 0.029 in the RC group, P < 0.05), without statistically significant differences from one to 12 months. Tear reservoir thickness showed a significant reduction at the one-month visit (122μm in the IC group and 126μm in the RC group, P < 0.05) that continued over time until the 12-month visit (195μm and 184μm lower compared with baseline (P < 0.05, Wilcoxon). Hyperemia and staining were significantly higher after SL removal when compared with baseline (P < 0.05) and maintained the same behavior over the 12 months. There were no severe adverse events during the entire follow-up period.
The authors determined that comfort enhancement promoted by SLs remained over the entire follow-up period. Despite no severe adverse events recorded over the 12 months of follow up, higher hyperemia and staining grades were found after SL removal when compared with a no-lens condition.
