NEW YORK — Conductive keratoplasty for the treatment of presbyopia has “exceptional” safety and visual results, according to a clinical investigator of the procedure.

Penny A. Asbell, MD, who participated in Food and Drug Administration clinical trials of conductive keratoplasty (CK), reported 9-month data on 78 eyes of 78 patients from the CK emmetropic presbyopia clinical trial here at the Ocular Surgery News Symposium on Cataract, Glaucoma and Refractive Surgery.

At 9 months, 87% of patients had binocular uncorrected visual acuity of 20/25 or better and J2 or better; 90% were 20/32 or better and J3 or better.

“CK is effective for inducing good binocular vision in presbyopic eyes,” Dr. Asbell said; “96% of patients report being satisfied, very satisfied or neutral.”

The clinical trial is investigating CK for the treatment of presbyopia in patients with refractions of +0.75 D to +3.00 D and less than 0.75 D cylinder. This study will continue for 1 year for full cohort results.

CK is currently available to treat patients 40 years of age or older who have hyperopia from +0.75 D to +3.25 D.
