RESUMEN
PURPOSE: To investigate the visual performance after unilateral implantation of an extended depth-of-focus intraocular lens (IOL) in patients with unilateral cataracts. METHODS: In this prospective study, uneventful phacoemulsification with LuxSmart IOL (Bausch & Lomb) implantation was performed in 25 eyes of 25 patients with unilateral cataracts. At postoperative 1, 4, 12, and 24 weeks, uncorrected and corrected visual acuity at far, intermediate, and near distances and the spherical equivalent in manifest refraction were measured. A Visual Function Index and modified Visual Function Index questionnaire were used to investigate glare, spectacle dependence, and satisfaction at 24 weeks in the eye that had surgery. RESULTS: At 6 months postoperatively, uncorrected distance visual acuity was 20/20 (0.0 logMAR) in 96% of cases, distance corrected intermediate visual acuity was 20/32 (0.2 logMAR) in all cases (60 cm), and distance corrected near visual acuity was 20/32 (0.2 logMAR) in 60% of cases (40 cm). The patient satisfaction score was 100% based on the Visual Function Index questionnaire for far and intermediate distance, respectively. No patients complained of the permanent photic phenomenon. No patients reported bilateral imbalance. All of the patients became spectacle independent for most of their intermediate activities at 60 cm. A total of 96% of the patients reported 100% contrast sensitivity in the Pelli-Robson test. CONCLUSIONS: The unilateral implantation of this EDOF IOL seems to be tolerated and effective in improving the visual function of patients with unilateral cataract with limited optical side effects such as halos or glare, providing spectacle-independent vision from far to intermediate object distances.
