PURPOSE: Evaluation which of the lenses: monofocal, bifocal or progressive, assure the best visual acuity in patients.
MATERIAL AND METHODS: 86 patients aged from 21 to 84 years were operated. Monofocal lenses were implanted in 30 cases, bifocal in 32 and progressive in 24 cases.
RESULTS: In 90% of patients with monofocal lenses and over 90% of patients in the remaining groups full uncorrected or corrected distance visual acuity was achieved. In groups with bifocal and progressive lenses full near visual acuity without correction, or with the same correction as for distance, was achieved by respectively 65.5% and 75% of patients.
CONCLUSIONS: In all three groups very good distance visual acuity was achieved. The best near visual acuity is assured by progressive lenses, in lower degree by bifocal lenses.
