PURPOSE: To report the 3-year postoperative safety and efficacy outcomes of the Acufocus corneal inlay.
DESIGN: Prospective nonrandomized noncomparative cohort study.
METHODS: The corneal inlay was implanted in the nondominant eye of naturally emmetropic presbyopic patients. Refraction, uncorrected near (UNVA), intermediate (UIVA), and distance (UDVA) visual acuities; corrected distance visual acuity(CDVA); contrast sensitivity; visual fields; subjective patient satisfaction and symptoms; and operative and postoperative adverse events and complications were evaluated.
RESULTS: The study enrolled 32 patients. The mean UNVA improved from Jaeger (J) 6 preoperatively to J1 at 3 years and the mean UIVA, from 20/40 to 20/25, respectively. At 3 years, 97% of eyes had a UNVA of J3 or better and 91% had a UIVA of 20/32 or better. The mean UDVA was 20/20, with all eyes achieving 20/32 or better. Nine eyes (28.3%) lost 1 line of CDVA, 1 eye (3.1%) lost more than 2 lines (3.8 lines), and 3 eyes (9.3%) gained 1 line. No inlay was explanted, and no inflammatory
reactions were observed. At 3 years, 15.6% of patients reported severe night-vision problems and 6.3% (versus 87.5% preoperatively) reported being dependent on reading glasses.
CONCLUSIONS: These 3-year results support the safety and efficacy of the corneal inlay to correct presbyopia in naturally emmetropic presbyopic patients. However, despite a significant gain in UNVA and UIVA, 28.3% of patients lost 1 line of CDVA.
