Purpose

To evaluate efficiency and speed of visual-perceptual processing in the area of searching the visual field in patients after cataract phacoemulsification with implantation of multifocal (MF IOL) and extended depth of focus intraocular lens (EDOF IOL).

Setting

Department of Sensory Organ Studies, Collegium Medicum, Nicolaus Copernicus University, Bydgoszcz Poland

Oftalmika Eye Hospital, Bydgoszcz, Poland

Division of Ophthalmology and Optometry, Department of Ophthalmology, Faculty of Medicine, Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Torun, Poland

Methods

12 patients with both eyes MF IOL implantation (Group 1) and 12 eyes with both eyes EDOF IOL implantation (Group 2) were included in the study. The average age of patients in group 1 was 56,00± 6,63 years and in group 2 57,33 ± 11,94 years. Between second and fourth week after second eye cataract phacoemulsification the attention and perceptiveness test and colour trial test were performed in two different light conditions by qualified psychologist.

Results

The average efficacy of the visual-perceptual processing in the area of searching the visual field in good light conditions was 711,17 ± 126,46 symbols in group 1 and 651,00 ± 141,90 symbols in group 2. In bad light conditions the results were 620 ± 135,19 and 522,33 ± 184,62 symbols respectively for group 1 and 2. The higher speed of visual processing and tracking was observed in group 1 (47,33 ± 10,91 s in good light condition and 54,33 ± 9,83 s in bed light condition) versus group 2 (54,67 ± 22,98 s in good light condition and 67,00 ± 32,89 s in bed light condition).

Conclusions

Less efficacy and speed of visual-perceptual processing in the field of searching and tracking the visual field was observed in patients with EDOF IOL comparing to MF IOL. These initial results indicate different adaptation processes for MF IOL and EDOE IOL in relation to visual-perceptual processing.
