PURPOSE: To evaluate the outcomes of myopic small incision lenticule extraction (SMILE) monovision in presbyopic patients. METHODS: This study included 49 presbyopic patients older than 45 years seeking surgical correction of myopia or myopic astigmatism who underwent bilateral SMILE with planned monovision in the SMILE Eyes Clinic Linz, Austria. Target refraction was plano for dominant (distance) eyes and ranged between -1.25 and -0.50 D for nondominant (near) eyes. Best-corrected distance visual acuity, uncorrected distance visual acuity (UDVA), uncorrected near visual acuity, as well as spectacle dependence were assessed after a mean postoperative period of 7.2 ± 4.8 months. RESULTS: Mean age was 49 ± 3 years and female to male ratio was 30:19. Distance eyes achieved a spherical equivalent correction of ±0.50 D from target refraction in 80% of patients and 96% were within ±1.0 D. Binocular UDVA of 20/20 or better was achieved by 90% of patients and all patients achieved 20/25 or better. The proportion of patients with a binocular UDVA of 20/20 or better who could read J2 or better amounted to 84%. Complete spectacle independence was achieved by 84% of patients and independence from reading glasses was achieved in 92% of cases. No patient requested refractive enhancement or monovision reversal. CONCLUSIONS: This first evaluation of SMILE monovision endorses the approach as a safe and effective option for the correction of presbyopia in myopic patients seeking refractive surgery.
