Hydrogel inlay may treat presbyopia with little effect on visual quality
Implantation of a corneal hydrogel inlay may treat presbyopia with only moderate effects on the optical system, according to a study.Twenty-two Korean patients with emmetropic presbyopia were included in the study. Raindrop near vision inlays (ReVision Optics) were implanted monocularly on the stromal beds of femtosecond laser-assisted generated corneal flaps of the patients’ nondominant eyes in order to assess optical quality.
