Federal Court Upholds Judgment for Allergan in Acular Suit
The United States Court of Appeals for the Federal Circuit has affirmed an earlier ruling in favor of Allergan and Roche Palo Alto, formerly known as Syntex, in a patent infringement
lawsuit against Apotex Inc, Apotex Corp. and Novex Pharma. In 2006, the Defendants appealed a ruling by the U.S. District Court for the Northern District of California that stipulates that the effective date of any
approval of the Defendants’ Abbreviated New Drug Application may not occur before U.S. Patent No. 5,110,493 expires in 2009. It also enjoins them from making any preparations that make, use, sell or offer for sale
ketorolac tromethamine ophthalmic solution 0.5% (Acular, Allergan) in the U.S. The Federal Circuit affirmed the District Court’s decision.
Clarification
In last week’s issue of CLToday, we reported on the discontinuation of Vistakon’s Acuvue Toric contact lenses. The company has since provided the following clarification: the
discontinuation is taking place in the U.S. only.
Abstract:
Probability of Corneal Infiltrates with Silicone Hydrogels
A study published in this month’s Archives of Ophthalmology reports corneal staining and limbal redness may predict corneal infiltrative events in silicone hydrogel patients on
a continuous-wear (CW) schedule. The researchers attempted to determine the cumulative probability and risk factors for developing corneal infiltrates during three years of CW lotrafilcon A lenses. A total of 317
patients participated in the study. The Kaplan-Meier unadjusted cumulative incidence of corneal infiltrate after CW was 5.7% after the first year, 8.5% after two years and 10.3% at the end of the study. Corneal
staining and limbal redness in the affected eye on a previous visit were significantly associated with the development of a corneal infiltrative event.
The researchers conclude that corneal staining and
limbal redness may predict the subsequent development of an infiltrative event among CW contact lens wearers. They calculate the probability of remaining free of any corneal infiltrates at the end of three years
of CW was 89.7%.

Editor's Commentary:
Evidence-Based Rules
Our abstract this week is a study I am very familiar with. I am one of the et als. I think it offers a key finding. Some have suggested legislation that would prevent those of us who
prescribe contact lenses from selling them in the future. If I were a member of the legislature presented with this rationale for prescribing and selling I'd ask for some valid, scientific evidence that supports
that it's important for doctors to monitor the patient to whom they have sold lenses.
This study says that in continuous-wear, detection of corneal staining may imply a future infiltrative event.
Therefore,
I believe it is one such instance of that evidence: If we continue to follow patients after we dispense the lenses, we can make sure they are safe and if need be, modify the prescription, i.e. prescribe other lenses or
modify the treatment plan with the current lenses. If the patient buys them elsewhere, they may not return for check-ups as readily or regularly
