Vistakon Says Rx Verification Works

According to Vistakon, a recent study proves the effectiveness of the company's prescription verification agreements with mail-order and Internet-based contact lens sellers. For the study, which was sponsored by Vistakon, 422 purchase attempts were made without valid prescriptions for various manufacturers' contact lenses. Mail-order and Internet companies filled only 8% of the invalid prescriptions for Vistakon lenses, compared with fill rates ranging from 89% to 96% for other manufacturers' contact lenses.

The study concludes that Vistakon's success results from the prescription verification requirements that the manufacturer has in place for its products. Purchases were made from the five largest mail-order companies, which represent 90% of the mail-order volume. The study employed testers who placed the orders for the contact lenses. The testers work for an independent company that specializes in investigations.

To remove any regional bias, 11 doctors from 10 states participated in the study. When contacted for verification, the study instructed each doctor to indicate that the prescription had expired or that the customer was "not my patient."

New Comfort Drops
CIBA Introduces Blink-Activated AQuify Drops

CIBA Vision has introduced its new blink-activated lens drop, AQuify, that replicates the behavior of the body's natural tears to keep lenses moist, proving long-lasting comfort to wearers of all types of contact lenses. AQuify contains sodium hyaluronate and according to CIBA, with each blink of the eye, actually becomes more spreadable. Also, because AQuify has a naturally disappearing preservative, CIBA says that even those suffering from preservative allergies or who have extra sensitive eyes can use it to help keep their eyes moist.

Choose the Best Treatment for a Common Condition
By Kirk L. Smick, O.D., Chairman, CE, AOA

The role of dry eye disease in our practices continues to increase as more people feel its affects because of a variety of circumstances (more women entering menopause, computer use, etc.).

Each dry eye patient requires individual treatment, not a "one-size-fits-all" attitude. We should look to tear brands that offer: 1) a variety of options, 2) quality ingredients and 3) the best outcome. We must consider tears that provide all levels of dry eye relief. The availability of preservative and preservative-free formulas affords us the opportunity to best treat those patients who at times can be deems an "annoyance" yet are just struggling with a frustrating condition, and more importantly, will remain loyal to us if we can make them more comfortable.

The role of conventional chemical preservatives in tears continues to spark debate. It's becoming more apparent that there are cytotoxic effects associated with them, while potentially causing extensive superficial epithelial erosion, BAK or benzalkonium chloride, can be toxic to the ocular surface. This point becomes important in more moderate or severe dry eye. The more severe the condition, the more susceptible the patient is to the harmful effects of preservatives.

Formulations without preservatives or with non-toxic oxidizing preservatives such as sodium chlorite or Purite, should be considered in every dry eye patient, especially those who have moderate to severe dry eye. Purite causes little membrane disruption and has virtually no cytotoxicity.

Carboxymethylcellulose (CMC) is the current best-selling artificial tear active ingredient on the market in the United States. CMC is formulated in several viscosities and continues to grow in popularity. Unique to U.S. active ingredients, it is a polyanionic substance, rich in negative charges, which allows for better ocular surface protection. This technology provides mucoadhesion as well as protection and comfort. Its performance acts independently of the ocular pH level.

The prevalence of dry eye will only continue to grow. Our patients will continue to return if we can help them alleviate the daily symptoms associated with the condition.

FDA Approves Generic Alphagan

The FDA recently approved Alcon affiliate Falcon Pharmaceutical's generic brimonidine tartrate ophthalmic solution 0.2%, which is the therapeutic equivalent to Alphagan (Allergan, Inc.) and is indicated for lowering intraocular pressure in patients who have open-angle glaucoma or ocular hypertension.

Patent Proceedings
Vistakon Makes Preemptive Move, B&L Gains German Support

Vistakon has filed for a declaratory judgement against CIBA Vision regarding Vistakon's new Acuvue Advance contact lens, which is currently awaiting FDA clearance.

Says Vistakon spokesperson Marc Monseau, "We believe that when launched, this lens will set a new standard by offering the comfort people expect from Acuvue 2 in a unique formulation that allows for greater oxygen permeability."

Vistakon says that it is confident that the technology behind its Acuvue Advance contact lens falls outside the scope of CIBA's patents and has asked the Court to affirm that Acuvue Advance will not infringe CIBA Vision's patent portfolio by seeking a declaratory judgement.

According to Scott Meece, CIBA Vision vice president and general counsel, Vistakon's actions are clearly a litigation tactic intended to publicize its belated plans to enter the highly successful silicone hydrogel contact lens market. He said, "It's unfortunate that Vistakon elected to prematurely engage in litigation, rather than fully exploring a reasonable business resolution to the infringement of our patents."

A continuing battle

In other news, in response to Bausch & Lomb's challenge that a Novartis AG (parent company of CIBA Vision) patent claiming to cover extended wear contact lenses lacked novelty and was anticipated by an earlier B&L patent, the European Patent Office (EPO) in Munich fully revoked Novartis's patent. According to B&L, it will immediately seek to once again sell its PureVision contact lenses in Germany. The company will now seek a stay of the German injunction and will ask the Irish court to stay Novartis patent proceeding against B&L in Ireland.

CooperVision Plans Fall Seminars for Education of Presbyopia

CooperVision has announced continuing education accredited seminars on presbyopia in support of its Frequency 55 multifocal contact lens. According to the company, the seminars will present the latest information on the correction of presbyopia and offer attendees CE credit at no charge.

"The correction of presbyopia remains one of the largest opportunities available to optometry today," says Nikki Iravani, O.D., of CooperVision.

The seminars are being planned in conjunction with the American Optometric Association's (AOA's) Contact Lens and Cornea Section (CLCS) Educational Forum.

CooperVision has arranged 16 venues across the country and may schedule additional seminars in 2004. The company plans to begin the series of seminars on October 21 in Chicago. For information or to register to attend one of the seminars, contact the AOA CLCS at (800) 365-2219, ext. 137, or CooperVision marketing at (800) 538-7850.
