Abstract
Introduction: The study has to determine whether implantation of diffractive multifocal lenses during cataract phacoemulsification causes distortion of the cognitive aspects of processing perceptual information.
Material and methods: 25 patients who underwent cataract phacoemulsification with the implantation of diffractive multifocal lens Acrysof Restor SN6AD1 in both eyes (multifocal group) and 26 patients with the implantation of monofocal intraocular lens Acrysof IQ SN60WF in both eyes (monofocal group) were enrolled. All patients underwent ophthalmic examination and cognitive function– Trial Making Test (Part A and Part B) and Stroop Test (Stroop Test 1 and Stroop Test 2) tests at least 6 months after cataract surgery of the other eye.
Results: Mean patient age and visual acuity with correction for near and far vision did not differ between groups. Average Trail Making scores were 32.80 ± 11.86 s and 84.08 ± 33.26 s for Parts A and B, respectively, in the multifocal group, while scores in the monofocal group were 36.61 ± 13.63 s and 93.34 ± 40.49 s in Parts A and B. Stroop Test scores were 79.09 ± 17.69 s and 133.64 ± 17.60 s for Stroop Test 1 and Stroop Test 2, respectively, in the multifocal group; in the monofocal group, scores were 82.04 ± 17.51 s and 152.88 ± 65.72 s, respectively. The groups did not differ for either test.
Conclusions: Differences between cognitive function tests results between patients with multifocal and monofocal intraocular lenses were not statistically significant suggesting the lack of influence of the type of lens on visual perception at least in good light conditions. Further clinical trials using more sophisticate tests in different light conditions are needed.
