Abstract/OtherAbstract:
BACKGROUND AND OBJECTIVE:To evaluate uncorrected distance, intermediate, and near visual acuity (VA), uncorrected near stereoacuity, the preferred reading distance, and reading speed after bilateral implantation of AcrySof ReSTOR SN6AD1 or SN6AD3 multifocal intraocular lens (IOL) (Alcon, Laboratories Fort Worth, TX). PATIENTS AND METHODS:Forty patients (80 eyes) from our hospital were prospectively enrolled in either the SN6AD1 group or the SN6AD3 group. There were 20 patients (40 eyes) in each group. Uncorrected distance and near VA, uncorrected intermediate VA at 40, 63, and 100 cm under high and low contrast, defocus curve, preferred reading distance, uncorrected near stereoacuity, and reading speed were evaluated 3 months postoperatively. RESULTS:Uncorrected intermediate VA at 40, 63, and 100 cm with high or low contrast was significantly better in the SN6AD1 group than in the SN6AD3 group (P < .05), with no difference in uncorrected distance VA or near VA (P > .05). The preferred reading distance in both groups was 38.5 and 32.8 cm, respectively. There were no statistically significant differences between groups in uncorrected near stereoacuity and reading speed (56.7 ± 45.4 vs 52.5 ± 35.4 seconds of arc and 174.2 ± 65.0 vs 195.3 ± 45.8 words per minute, respectively). CONCLUSION:Patients receiving the SN6AD1 IOL achieved better intermediate VA under high or low contrast and a more comfortable reading distance than patients receiving the SN6AD3 IOL without compromising uncorrected near and distance VA, uncorrected near stereoacuity, and reading speed.
