SAN FRANCISCO — A +3.0 add power IOL improves intermediate vision while delivering similar vision at near and distance as a +4.0 add power IOL.

"The +3 add did not cause any loss of vision at near or distance vision," Robert P. Lehmann, MD, said at the American Society of Cataract and Refractive Surgery meeting here. "We saw an improvement of 1 to 2 lines in intermediate vision."

According to results from a randomized, parallel group, subject-masked, multicenter trial, the ReStor +3.0 D add power IOL (Alcon) increased near uncorrected best distance by about 6 cm in 138 patients when compared with 134 patients who received a ReStor +4.0 D add power IOL (Alcon).

Intermediate visual acuity was 0.13 logMAR at 50 cm, 0.16 logMAR at 60 cm and 0.21 logMAR at 70 cm in patients in the +3.0 group, but 0.29 logMAR at all three distances in the +4.0 group. Dr. Lehmann said that 95.7% of patients in the +3.0 group had a combined distance, near and intermediate visual acuity of 20/40 or better, compared with 65.7% in the +4.0 group.
