BARCELONA — A light adjustable lens from Calhoun Vision, now commercially available in Europe, is showing successful outcomes in a high percentage of patients, according to one surgeon.

José L. Güell

The lens has a 6-mm silicone optic and PMMA haptics. It is inserted in the bag like a normal lens, but the dioptric power is adjusted and "locked in" after implantation by light irradiation.

"The adjustment is simple, very similar to a YAG procedure," José L. Güell, MD, said at the meeting of the European Society of Cataract and Refractive Surgeons here.

Personally, he has implanted 49 light adjustable lenses, or LALs, since 2005, and nearly 400 have been implanted by other surgeons in Europe.

"Predictability in adjusting spherical and cylindrical errors is very high," Dr. Güell said. "More than 90% of our patients were within 0.25 D, and all our patients within 0.5 D of intended correction. No loss of BCVA was reported."

The LAL, he said, is particularly useful in patients in which biometry has obvious limitations, such as following corneal refractive surgery or keratoplasty procedures.
