Hydrogel corneal inlays show promise for treatment of presbyopia
SAN FRANCISCO — Hydrogel corneal inlays may be a potential treatment for presbyopic patients, resulting in no loss of binocular vision and corneal clarity, according to a physician here.
"The inlay has the effect of changing the anterior curvature of the cornea," Stephen G. Slade, MD, said at the American Society of Cataract and Refractive Surgery meeting.

The multicenter, prospective study included the first 75 eyes of 75 patients who reached 6 months of follow-up in the phase 3a study.
Mean uncorrected visual acuity was 20/63 in the treated eye; 50% gained more than five lines at 3 months postoperative.
"These patients have a truly rapid return of vision and a LASIK-like postoperative course in terms of comfort and drops," Slade said.
The corneal inlays (ReVision Optics) can be centered precisely on the laser, he said.
"Keratophakia [is] the reason I’m so enthusiastic about this. It is easily centered and removable," Slade said.
