Short-term visual and refractive outcomes after toric lens implantation

Abstract

Purpose: To evaluate postoperative visual acuity and refractive status of eyes implanted with a toric intraocular lens (IOL) to correct co-existing, regular corneal astigmatism in cataract patients from two clinics in Córdoba and Buenos Aires, Argentina.
Methods: This observational, retrospective study included patients from SOF Córdoba and Buenos Aires clinics who underwent cataract surgery with toric IOL implantation (monofocal Hanita VisTor™). Data was analyzed by student’s t test and Wilcoxon’s test. Statistical significance was set at p<0.05.
Results: 16 eyes from 11 patients were included in the sample. There was a statistically significant difference between pre- and postoperative astigmatism and visual acuity. Mean (±SD) residual refractive astigmatism was 0.8 D (±0.39), with a maximum of 1.75 D and a minimum of 0.25 D. The mean reduction of astigmatism was 1.58 ± 0.65 D (p<0.01). The mean reduction of uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) was 0.44 and 0.16 logMAR, respectively.
Conclusion: Implantation of Hanita VisTor IOL™ is effective to correct corneal refractive astigmatism during cataract surgery and it provides excellent UCDA and CDVA. Although our sample is yet small, the refractive and visual acuity results are comparable to those from other toric IOL.
