LAS VEGAS — The Tetraflex accommodating IOL from Lenstec is showing good results to date in a multicenter clinical trial, according to a speaker here.

David C. Brown, MD, discussed interim results of the trial at Refractive Surgery Subspecialty Day preceding the American Academy of Ophthalmology meeting. The Tetraflex is a posterior chamber poly-HEMA accommodating IOL with a 5.75-mm optic.

In the trial, which began in September 2005, there are currently 69 eyes with 1-month follow-up. Dr. Brown presented data on 27 eyes of 27 patients with 3 months' follow-up. He said 88% of patients can see 20/60 or better uncorrected at distance, and 94% can see 20/80 or better at near with distance correction.

"Patients do not have any complaints of dysphotopsia, glare or halos and enjoy a wide range of activities at both distance and near," Dr. Brown said. "We're getting 94% of our Tetraflex patients reading newsprint."

There have been no intraoperative complications in the trial, and no incidences of capsular contraction, he noted.
