Long-Term Visual Outcomes of Hydrogel Near-Vision Inlay Implantation in Presbyopic Eyes: Hungarian Experience
Narrative Responses:
Purpose
To report our long-term patient outcomes in Hungary, 2 years or more after implantation of a hydrogel near vision corneal inlay (Raindrop) to treat presbyopia.
Methods
Fifteen (15) presbyopic patients (8 emmetropes, 7 hyperopes) were treated in the non-dominant eye with Raindrop Near Vision Corneal Inlay (ReVision Optics Inc.). The Raindrop inlay is fabricated from a biocompatible, clear and permeable hydrogel material (80% water content) and is implanted under a minimum 150-micron femtosecond flap. In hyperopic patients the inlay was implanted in the non-dominant eye after concurrent LASIK correction. In emmetropes, the only treatment was inlay implantation.
Results
Mean preop MRSE: +0.09 D (range: -0.25 D to +0.50 D) for emmetropes, +1.65 D (range: +1.25 D to +2.00 D) for hyperopes. Binocular UNVA (mean, decimal) improved from 0.22 preop to 0.9 at 2 years, a gain of over 6 lines on average. Binocular UDVA improved from 0.77 preop to 1.3 at 2 years. Visual acuities remained stable over time, with a tendency towards improvement. Two eyes had mild transient haze early during the postoperative period (6 month visit) that resolved completely after treatment with topical steroids, all corneas were clear at 2 years.
Conclusion
The Raindrop inlay achieved good long-term outcomes with stable visual acuity and no complications at 2 years. This inlay is an effective tool for the surgical correction of presbyopia in both emmetropes and patients with refractive errors. Results are consistent and stable over time.
