To evaluate visual performance of presbyopic patients after treatment with both LASIK and implantation of a corneal inlay to simultaneously treat their refractive error and presbyopia.
International multi-center study
A series of 3,896 ametropic presbyopes (-5.0D to +3.0D and ?3.0D of cylinder) between 45-65 years of age from 11 centers worldwide was analyzed. A femtosecond-laser was used to create a 200-micron flap in the non-dominant eye and an excimer ablation was performed aiming for a post-operative refractive outcome of -0.75D. The inlay was then positioned on the stromal bed over the 1st Purkinje image and the flap repositioned. Where necessary, the fellow eye was treated with a traditional LASIK procedure with a refractive target of plano. The outcomes measured were spherical equivalent refraction (MRSE), uncorrected distance visual acuity (UCDVA), and uncorrected near visual acuity (UCNVA) in the inlay eye.
At 12 months, the mean MRSE was -1.1D ± 0.9D. UCDVA in the inlay eye improved from 0.3 ± 0.4 (20/60) preoperatively to 1.0 ± 0.3 (20/20) at 12 months postop. Preoperatively, the UCNVA in the inlay eye was 0.5 ± 0.4 (20/40) and 12 months postoperatively the UCNVA was 0.8 ± 0.2 (20/25).
The combination of LASIK and inlay implantation improves near and distance vision for ametropic presbyopes.
