Hydrogel corneal inlay improves near, intermediate, distance vision at 3 months

A hydrogel corneal inlay improved near, intermediate and distance vision, regardless of preoperative refractive error, according to a study presented at Hawaiian Eye 2014.
Roger F. Steinert, MD, OSN Cornea/External Disease Board Member, spoke about the Raindrop near vision inlay (ReVision Optics).
“This is really better than anybody expected,” Steinert said. “It’s providing uninterrupted functional vision and satisfaction across a very wide range of preop refractive errors. … We think the real sweet spot is going to be somewhere around the very low hyperopic side and not higher than +1.5 D.”

The study included 188 patients with a mean age of 51 years and mean preoperative manifest refraction between –0.5 D and +1.5 D.
Mean postoperative monocular uncorrected near visual acuity exceeded 20/25 and approached 20/20 in all eyes at 3 months. Near visual acuity was unaffected by age and preoperative refractive error, Steinert said.
Mean monocular uncorrected intermediate visual acuity exceeded 20/25 in all eyes.
Mean monocular uncorrected distance visual acuity decreased slightly in eyes with manifest refraction of –0.5 D to +0.5 D but improved in eyes with manifest refraction of +0.75 D to +1.5 D. Distance visual acuity was 20/25 or better in eyes with preoperative refraction of +0.25 D to +1.5 D.
Mean patient satisfaction was four on a scale of five, Steinert said. –by Matt Hasson
