To examine visual and refractive outcomes, spectacle independence and patients satisfaction after toric multifocal IOL surgery.
Prospective non-comparative case series. Patients with corneal astigmatism and clinical significant cataract were included. In all patients the ALCON Acrysof Toric Multifocal IOL was used. IOL was calculated for emmetropia in both eyes using the IOL master (Carl Zeiss, Germany) and the SRK II formula. IOL selection was performed using the online ALCON toric IOL calculator. Patients were followed at day 1, week 1, 1, 3, 6,12 and 24 months. At each visit, UCDVA, CDVA, Near Visual acuity at 30 cm and intermediate visual acuity at 80 cm were measured. Spectacle independence was analyzed subjectively. Contrast sensitivity was measured, and defocus curves were calculated for all patients. Statistical analysis was performed using SPSS v.16. Students paired t-Test and Wilcoxon rank test were used to compare pre and postoperative variables.
Twelve eyes of 6 patients were included. The preoperative mean UCDVA (logMAR) was 0.95, and CDVA (logMAR) was 0,13. One month after surgery, the mean uncorrected distance visual acuity (logMAR) was 0.12, corrected distance visual acuity (logMAR) was 0,06. The preoperative mean refractive cylinder (RC) was -2.85. After a 6-month follow-up, the average RC was -0.24 D (p<0.001).
Multifocal Toric IOLs improve both distance and near uncorrected distance visual acuity thus providing spectacle independence.
