Materials and Methods: This analysis comprised the right eyes of 220 patients who had bilateral implantation of bilateral AcrySof SN60D3 IOL. The best corrected distance visual acuity, distance-corrected (near intermediate, far) visual acuities, distance glare test under mesopic conditions, and patient satisfaction were measured. The results were compared according to age, preoperative astigmatism, and preoperative visual acuity.
Results: For the comparison of age, in the first group, age younger than 65 years, the results were more satisfactory than they were in the second group, except for the halos. In the grouping according to preoperative astigmatism, the first group had 0.5 diopter (D) or less preoperative astigmatism, while the second group had more than 0.5 D; and mean distance logMAR and mean halo values were better in the first group. For preoperative visual acuity, the first group had over 0.5 logMAR preoperative visual acuity, while the second group had 0.5 logMAR. For this comparison, in the first group, near vision logMAR, satisfaction with near sight, satisfaction overall, and glare test results were better.
Conclusions: The AcrySof Natural ReSTOR IOL provided good visual performance at distance and near. The younger age group had better compliance with the lens while halos were still a problem. Astigmatism less than 0.5 D gave favorable results, while preoperative good vision had a negative correlation with postoperative intermediate vision.
