Real-world outcomes of cataract surgeries using a new type of enhanced monofocal toric intraocular lens

Abstract

In this single-center study, 62 eyes of 41 patients with regular astigmatism, who received cataract surgery with TECNIS Eyhance Toric II intraocular lens (IOL) insertion between January 1, 2022, and June 30, 2023, were retrospectively investigated. At 3 months postoperatively, there were significant improvements in the mean logMAR uncorrected distance visual acuity (VA) (from 0.64 ± 0.42 to 0.11 ± 0.13, p < 0.001) and logMAR corrected distance VA (from 0.28 ± 0.30 to 0.03 ± 0.06, p < 0.001). An 81.9% reduction in astigmatism (from 1.66 ± 0.49 D corneal cylinder preoperatively to - 0.30 ± 0.39 D refractive cylinder at 3 months postoperatively, p < 0.001) was observed. In the vector analysis, the average of difference vector was 0.27 ± 0.35 D, and the average correction index was 1.09 ± 0.22, revealing a minimal overcorrection. Mean IOL misalignment at 3 months postoperatively was 0.68 ± 4.17°, and average absolute misalignment was 3.41 ± 2.44°. Defocus curves showed < 0.2 logMAR range between - 0.85 and 1.27 diopters, and distance-corrected near and intermediate VA were 0.38 ± 0.14 and 0.17 ± 0.13, respectively. These results indicate that the new enhanced monofocal toric IOL is a safe and effective treatment for astigmatic eyes with cataract.
