Commercial Experience With Clear Hydrogel Corneal Inlay: Comparison With Monovision LASIK
To report my commercial experience with Raindrop Near Vision Inlay for the treatment of presbyopia and to compare retrospectively with my monovision LASIK patients.
Nineteen (n=19) patients were implanted with the Raindrop Inlay after creating a corneal flap of 150 microns and 8 mm diameter with 150 kHz IntraLase femtosecond laser. Concurrent laser ablation was performed on 11 patients with a targeted refraction of +0.75 D in the inlay eye. A 3 month postop steroid regimen was used to facilitate the healing process. Visual acuities for far and near were tested at several time points. Results are compared retrospectively to an age-matched cohort of monovision LASIK patients.
At 3 months, all Raindrop and monovision LASIK patients achieved binocular uncorrected distance of 20/20 (1.0) or better. 90% of the Raindrop and 85% of the monovision LASIK patients achieve binocular uncorrected near 20/25 (0.8) or better. Monocularly UDVA was better in the Raindrop group with 84% achieving 20/40 (0.5) or better compared to 50% in the monovision LASIK group. Distance corrected vision remained stable for both groups from preop to 3M. Quality of life, stereopsis, patient satisfaction and spectacle independence will be presented at the meeting.
In my experience, the Raindrop Inlay provides similar near vision improvement as monovision LASIK, but with less monocular distance vision impairment. Raindrop is a viable commercial product for the correction of presbyopia in my practice.
