PURPOSE: To assess the near and distance VA achieved with implantation of the ReSTOR SN60D3 and SN6AD1 multifocal IOL after cataract surgery.

METHODS: 100 eyes of 69 patients who underwent uneventful bilateral or unilateral cataract surgery were randomized to undergo implantation with SN60D3 (64 eyes) or SN6AD1 (36 eyes) multifocal IOLs. Outcome measurements included uncorrected and best-corrected distance visual acuity, near visual acuity and spherical equivalent. Patients were followed for 6 months following surgery. Data were analyzed using SPSS for Windows. Significance of the difference achieving a specific visual acuity level in different lens groups was evaluated using ANOVA test. A P value <0.05 was considered statistically significant.

RESULTS: No difference in mean spherical equivalent, mean postoperative UCDVA, BCDVA among the two groups was noted for entire follow-up period. The SN6AD1 lens was better than SN60D3 lens for UCNVA with 81.8% achieving J2 compared to 57.6% of SN60D3, however UCNVA were better with SN6AD3 than SN60D1 at 6 month.

CONCLUSIONS: Two diffractive IOLs provide similar uncorrected and best corrected distance visual acuity. However, the SN60D3 lens provides a little better uncorrected near visual acuity than the SN60D1 at 6 month.
