In a prospective, randomized clinical trial, 42 patients received a monofocal intraocular lens and 38 a multifocal lens after extracapsular cataract extraction. Patients were examined three, six, and 12 months after surgery. Uncorrected visual acuity was 20/40 or better in 57% of monofocal and 58% of multifocal patients; 12% and 52% had near uncorrected visual acuity of J1 to J2, respectively. Best corrected visual acuities were not significantly different. Forty-eight percent of the multifocal and 8% of the monofocal group did not require spectacle correction. On a patient satisfaction questionnaire, 60% of all patients reported discomfort when using spectacles for near vision. Patients in the multifocal group were more satisfied with their near vision than those in the monofocal group. The difference in satisfaction was not significantly different although more multifocal patients reported visual phenomena (e.g., glare, halos). Mean contrast sensitivity for the monofocal group and the multifocal group was 1.73 and 1.70, respectively. At low contrast sensitivities, the difference was not significant although the monofocal patients scored better.
