To report our experience in Hungary with 2 years follow-up after implantation of a hydrogel near vision corneal inlay (Raindrop) to treat presbyopia.

15 presbyopic patients (8 emmetropes, 7 hyperopes) were treated in the non-dominant eye with Raindrop Near Vision Corneal Inlay (ReVision Optics Inc., Lake Forest, CA) under a 150 ?m corneal flap created by a FS Laser. The inlay is 2.0 mm in diameter, with a central thickness of 30 ?m. It is fabricated from a biocompatible, clear and permeable hydrogel material (80% water content). In the Hyperopic patients (preop. refraction: +0,75D < +3,0D and astigmatic correction <+ 1,5D) the inlay was implanted in the non dominant eye after concurrent LASIK correction. In emmetropes the only treatment was inlay implantation.
The inlay was easily implanted under the corneal flap and centered over the pupil. Even in cases of mild decentration of the inlay (2 eyes), the visual acuity and patient satisfaction were good. Near visual acuity (monocular, uncorrected) improved to a mean of 0.1 logMAR (0.8 decimal), a gain of approximately 5 lines on average. Intermediate acuity improved on average 2 lines monocularly, with a mean value of 0.1 logMAR (0.8 decimal). The visual acuites remained stable over time, with a tendency towards improvement. No patient lost 2 or more lines of BCDVA in the treated eye. Two eyes had mild transient haze early during the postoperative period (6 month visit) that solved completely after treatment with topical steroids (FML). In 2 patients the inlay was slightly decentered; both patients reported good vision and high satisfaction. All patients retained > 1,0 binocular vision for distance, intermediate and near.
The Raindrop Near Vision Inlay demonstrated good visual outcomes, excellent patient satisfaction and is well tolerated. This inlay is an effective tool for the surgical correction of presbyopia in both emmetropes and patients with refractive errors. The presence of this particular inlay steepens the anterior corneal curvature, naturally increasing the optical power of the eye to provide improved near and intermediate vision. Importantly, these patients do not lose binocular distance vision.
