Corneal inlays appear to offer effective presbyopia correction

SAN DIEGO — Three optical approaches potentially provide good near and distance vision in presbyopia treatment, with technologies in development in each approach, a clinician said here.
The three approaches are near power in the pupil center, distance power in the pupil center and the pinhole effect, Roger F. Steinert, MD, OSN Cornea/External Disease Board Member, said at the American Society of Cataract and Refractive Surgery meeting.
Dr. Steinert discussed the technologies, including the Kamra intracorneal inlay (AcuFocus), a pinhole corneal inlay option; the PresbyLens (ReVision Optics), a hydrogel corneal inlay for center near vision; and the Flexivue (Presbia), a hydrophilic corneal inlay for center distance vision.
He also outlined procedure outcome comparisons between the technologies and presbyLASIK (Nidek) and laser remodeling of the cornea.
"PresbyLens [has] the advantage as far as the best correction of near and intermediate vision; presbyLASIK, at least in Nidek results, seems to have the least loss of distance visual acuity," Dr. Steinert said. "Good near and intermediate was provided by the hydrogel corneal inlays, as well as reversibility. The biocompatibility long term, of course, is going to be the subject of extensive ongoing testing. So far, so good, but time will tell."
