Presbyopia Treatment Using New Hydrogel Corneal Inlay With Concurrent LASIK: Commercial Experience in High-Volume LASIK Clinics in Japan
Narrative Responses:
Purpose
To report early postoperative clinical results in myopic presbyopes implanted with novel corneal inlay (Raindrop™, ReVision Optics, US.).
Methods
One hundred and seven (n=107) patients were implanted with Raindrop Near Vision Inlay in a high volume multicenter LASIK clinic in Japan. Excimer laser ablation in both eyes targeting plano, the transparent inlay was delivered in the non-dominant eye centering it over the light constricted pupil above the stromal bed. Manifest refraction, near and distance visual acuities were collected at preop, 1W, 1M, and 3M.
Results
Patient age (mean ± SD) 51.3 ± 4.4 years old, Average MRSE (preop, 1W, 1M, and 3M) were: -2.4D, -0.96D, -1.0D, and -1.1D (inlay eye); -2.5D, -0.08D, -0.04D, and -0.03D (non inlay eye). Average monocular (inlay eye) near visual acuities improved from (decimal) DCNVA: 0.30 ± 0.17 to UNVA: 0.73 ± 0.25 at 3M. Binocular UVAs at 3M were 1.28 ± -0.26 for distance and 0.78 ± 0.23 for near. 2 cases (1.8%) of corneal haze were noted, one due to poor postop medication compliance. Both cases resolved with steroids.
Conclusion
Raindrop inlay was successfully integrated into my high volume LASIK clinic yielding good postop binocular vision, stable refraction, low complication rates. Postop refractions were targeted to be more myopic due to the increased near demands of the local population. Raindrop inlay appears to be a safe and viable treatment option.
