Abstract
PURPOSE: To assess the preliminary clinical outcomes and patient satisfaction of the new enhanced depth of focus (EDOF) LuxSmart™ intraocular lens IOL and to compare with a conventional monofocal IOL (Akreos™) in patients who had undergone bilateral cataract surgery. METHODS: Twelve patients underwent bilateral LuxSmart IOL implantation, and twelve underwent bilateral Akreos IOL implantation. Best-corrected distance (CDVA) and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm and defocus curve were assessed. Patients-reported visual function was inquired by Catquest-9SF. The presence of photic phenomena was evaluated. A p-value lower than 0.05 was considered for statistical significance. RESULTS: The mean IOL power was +21.90D in LuxSmart group and +22.30D in Akreos. Monocular UDVA (p = 0.32) and CDVA (p = 0.52) did not differ between groups. The average binocular UIVA (0.18 ± 0.12 logMAR vs. 0.30 ± 0.13 logMAR, p < 0.001) and UNVA (0.38 ± 0.14 logMAR vs. 0.44 ± 0.17 logMAR, p = 0.02) were higher in LuxSmart IOL group. No patients reported disabling photic phenomena in either group. CONCLUSION: This study shows that new LuxSmart EDOF IOL achieved higher performance for intermediate and near vision compared with a conventional monofocal IOL, without increasing the risk of dysphotopsias. LuxSmart may be an attractive and safe option for patients who desire spectacle independence for distance and intermediate vision after cataract surgery.
