OBJECTIVE: To evaluate the maximally corrected visual acuity and contrast sensitivity under photopic and mesopic conditions with or without glare in pseudophakic patients implanted with either foldable or rigid intraocular lenses.
MATERIAL AND METHODS: A total of 83 patients after cataract surgery were examined at baseline and 8-12 weeks later: 47 patients with age-related macular degeneration (Group 1) and 36 patients without ocular comorbidities (Group 2). Contrast sensitivity was measured using a Ginsburg Box, VSCR-CST-6500.
RESULTS: Using logistic regression analysis it was revealed that probability of clinically significant improvement of contrast sensitivity under photopic conditions with and without glare in the patients with implanted foldable lenses increased by 3.1 times (95% PI 1.6-5.9, P<0.001) compared with the patients with rigid lenses. In mesopic conditions with and without glare, it increased by 3.9 and 3.0 times (95% PI 1.9-7.8 and 1.6-5.9, respectively, P<0.001) in the patients with foldable lenses as compared with the patients with rigid lenses.
CONCLUSIONS: The foldable intraocular lenses have shown better contrast sensitivity than rigid lenses under both mesopic and photopic conditions with or without glare. Postoperatively, there was no significant difference in visual acuity concerning the types of the implanted intraocular lenses.
