We have covered the Federal Trade Commission’s (FTC) revised contact lens rule extensively (https://www.clspectrum.com/issues/2021/may-2021/contact-lens-prescribing-now-and-in-the-future). Now, we have seen the FTC and Department of Justice enforce parts of the rule, particularly as it relates to unauthorized distribution of contact lenses by an online-seller-turned-rogue-prescriber. What is less clear has been the true impact of the revised rule on your contact lens practice. Has it been as burdensome as you thought? Have you experienced anything unanticipated otherwise? Please share your thoughts with us at cltoday@pentavisionmedia.com.

Tear Supplementation Contact Lenses

Application of artificial tears commonly provide—at best—temporary relief from dry eye symptoms. Polyvinylpyrrolidone (PVP) K-90 is widely used to manage dry eye syndrome (DES). The marketed eyedrop solutions need frequent instillation. A study looked at the ability of a contact lens coated with PVP to release the agent into the tear film.1

In the study, PVP K-90 was loaded and coated to a soft contact lens. The swelling studies suggested improvement in the water uptake (hydration) property of the contact lenses due to the presence of PVP K-90. The optical transparency was within an acceptable range. In animal studies, the coated contact lens showed higher tear volume in comparison to the respective uncoated contact lenses and an eyedrop solution. The study authors noted that this is a novel approach of coating a high amount of PVP K-90 on lenses for sustained release to manage several ocular diseases like dry eye syndrome, conjunctivitis, and other ocular injuries.

This is just another example of a large number of studies being published recently regarding the use of contact lenses to perform beyond just simple visual correction. In fact, Johnson & Johnson recently received U.S. Food and Drug Administration (FDA) approval for its Acuvue Theravision contact lens with ketotifen (etafilcon A drug-eluting contact lens with ketotifen). Ketotifen is a well-established antihistamine used for the topical treatment of ocular allergy. Delivery of medications, addressing dry eye, addressing allergic eye symptoms, and antimicrobial functions all are being studied and hopefully more will be available to us clinically at some point in the not-too-distant future.

Old Versus Young

Dry eye disease (DED) is a debilitating condition occurring in all ages, with increased frequency in older subjects and especially in advanced-age women. An interesting 2022 literature review article aimed to gather insight into the possible differences between dry eye in patients younger than 40 years and those older than 60 years.1 The study reports that younger patients may be exposed to risk factors because of working or recreational activities.

Patients who are under 41 years of age often have severe subjective symptoms and incomplete blinks, with a thin lipid layer, but the number of functioning meibomian glands is elevated and glandular loss is limited. However, in older subjects, glandular loss is a predominant feature along with ocular surface inflammation. These characteristics may be related to the frequent factors producing DED in the elderly, such as systemic inflammatory diseases, glaucoma, and topical or systemic drug use. The pathophysiologic changes of the ocular surface responsible for eye dryness are linked with inflammation and neurosensory abnormalities and may occur with different features in young patients compared with older ones.

The authors of this review suggest that the symptoms observed between patients of different ages may require differentiated treatment strategies for young and older subjects.

Abstract
 

Differentiating Between Contact Lens Warpage and Keratoconus Using OCT Maps of Corneal Mean Curvature and Epithelial Thickness

The purpose of this study was to formulate an Epithelial Modulation index to differentiate between eyes that have contact lens warpage and keratoconus.

Normal eyes and eyes that had either contact lens warpage or keratoconus were scanned by a Fourier-domain optical coherence tomography (OCT) system. Maps of epithelial thickness and anterior surface mean curvature were generated and converted to deviation maps by subtracting the average maps from a healthy population. The Epithelial Modulation index was defined as the covariance between the two types of deviation maps. A logistic regression model was used to classify eyes as non-keratoconus (normal or warpage) or keratoconus (manifest, subclinical, or forme fruste).

The average Epithelial Modulation index value for normal eyes was –0.6µm/m ± 1.0µm/m. Eyes that had keratoconus were characterized by coincident high anterior surface mean curvature and low epithelial thickness, resulting in a high Epithelial Modulation index (manifest: 103.0µm/m ± 82.9µm/m, subclinical: 37.0µm/m ± 23.0µm/m, forme fruste: 7.3µm/m ± 13.2µm/m). The Epithelial Modulation index was closer to normal for eyes that had warpage (–1.9µm/m ± 4.0 µm/m). The classification accuracy of the Epithelial Modulation index during five-fold cross-validation of the logistic regression model was 100% ± 0% for normal eyes and 99.0% ± 2.0% for eyes that had warpage. The accuracy was 100% ± 0%, 100 ± 0%, and 53.1% ± 1.5% for the manifest, subclinical, and forme fruste keratoconus groups, respectively.

The authors concluded that the Epithelial Modulation index is useful in distinguishing eyes that have secondary epithelial modulation (keratoconus) from those that had primary epithelial deformation (contact lens-related warpage).
