Court Rules on Ocular Insight Claims

A United States district court has ordered Ocular Insight, Inc., to stop making certain claims about its Clear 58 contact lenses. The New York court said Ocular Insight must permanently discontinue stating or communicating in any of its advertising or promotional materials that the company's Clear 58 contact lenses are approved by the FDA as a generic equivalent lens to Vistakon's Acuvue 2 contact lenses; that Clear 58 is an exact duplicate or is identical to Acuvue 2; that Clear 58 is approved by the FDA; and that Clear 58 is a generic equivalent to Acuvue 2. The ruling was in response to a complaint filed in July 2008 by Johnson & Johnson Vision Care, Inc.
     "Contact lens design and the manufacturing process are two key factors that differentiate contact lenses," said Naomi Kelman, president, Americas, Vistakon. "The proprietary lens design and manufacturing process of all Acuvue Brand Contact Lenses are unique. In many cases, these differences in design and manufacture distinguish them from other contact lenses in areas such as comfort, eye health and vision."
     Mark Levin, president, Ocular Insight, Inc., said the company amended the claims once it received initial notice from Johnson & Johnson. He said the company "chose not to spend significant resources" fighting the claims. "Instead, we are determined to concentrate our resources on introducing safe and efficacious contact lenses to the ophthalmic community at price points designed to convert their low margin contact lens practice to a high margin practice."

World Sight Day Declared in Wisconsin

The Wisconsin Optometric Association (WOA) and Optometry Giving Sight announced that Wisconsin Gov. Jim Doyle proclaimed Oct. 9 as World Sight Day in Wisconsin.  
     World Sight Day is a global event that seeks to bring awareness and action to the elimination of avoidable blindness by the year 2020. Each year, Optometry Giving Sight issues its World Sight Day Challenge and asks O.D.s to donate exam fees, make a regular donation and plan a practice celebration in order to raise funds for projects that provide vision care, local training and infrastructure support for people in countries where such services don't currently exist.

Abstract: Eye Blink Frequency and Type in Relation to 3- and 9-O'Clock Staining and Gas Permeable Contact Lens Variables

The primary goal of this study was to evaluate if there is a difference in frequency and in completeness of eye blinks (type of eye blink) in GP lens wearers experiencing 3- and 9-o'clock staining compared with GP lens wearers without substantial staining and non-lens wearers.
     The study involved 26 non-lens wearers and 55 GP lens wearers, with and without 3- and 9-o'clock staining. Every eye blink over a five-minute period was categorized as a complete eye blink, incomplete eye blink, or an eye blink attempt. In addition, type of lens fit (interpalpebral vs. lid attachment), lens-to-cornea fit (flat vs. steep), spherical equivalent of the refraction, and corneal coverage (on-eye lens diameter) were analyzed.
     No difference in overall eye blink frequency was found between non-lens wearers (group I, n = 26), GP lens wearers with less than grade 1 corneal staining (group II, n=25) and GP lens wearers with grade 1 or more corneal staining (group III, n = 30). Fewer complete eye blinks, more incomplete eye blinks and more eye blink attempts were seen in group III than in group I or II (p < 0.01, p = 0.03, p < 0.01, respectively). Fewer complete eye blinks and more eye blink attempts (p < 0.01 for both) were found in interpalpebral lens fits than in lid attachment fits. Fewer complete eye blinks (p = 0.02) and more incomplete eye blinks (p = 0.03) were found with lenses rated as large or optimal in size than with lenses rated as small.
     The authors concluded that GP lens wearers experiencing 3- and 9-o'clock staining showed a different eye blink frequency for individual types of eye blinks, but not for overall eye blinks. Fewer complete eye blinks, more incomplete eye blinks, and more eye blink attempts were observed in GP wearers with 3- and 9-o'clock staining compared with wearers with minimal staining and non-wearers. In addition, some individual contact lens variables were associated with more incomplete eye blinks.

Editor's Commentary: Fill in the Blanks to Solve a Frequent Problem

As we know clinically, meibomian gland disease and associated conditions such as blepharitis are frequent in our patient populations. Interestingly, we do not have good epidemiological data on the actual prevalence of these conditions. We think that these conditions may be particularly high in our contact lens wearers, contributing to the frequent complaints of dryness and discomfort. How are you and your colleagues addressing this problem clinically? How often and what ways are you using to evaluate the lid margins and meibomian glands? Do you evaluate lipid expression? Are you routinely using the traditional management methods of warm compresses and lid hygiene? New pharmaceuticals are being targeted for the treatment of lid disease and early trends are thought provoking. Hopefully with this, and other forthcoming treatments, we will be able to provide more relief for this burning problem. Please share your comments with me and continue to send your thoughts, feedback, and tips to tips@CLtoday.com.
