The study plans to treat 50 eyes and follow them for 1 year, according to Dr. Stodulka, the operating surgeon in the single center study that is evaluating laser astigmatic keratotomy using the Victus Femtosecond Laser Platform (Technolas, Bausch + Lomb).
So far, 19 eyes with an average preoperative manifest cylinder had completed follow-up. At 1 year, manifest cylinder averaged 0.17 D and was ≤0.5 D in 95% of eyes, said Dr. Stodulka, chief executive officer, Gemini Eye Clinic, Czech Republic.

He reported that the astigmatic correction was stable during follow-up and distance best corrected visual acuity was unchanged or improved compared with the preoperative level in all eyes. Among 27 eyes seen at 6 months, 75% had ≤0.5 D of residual cylinder.
