Purpose

There are many psychological tests widely used to evaluate different aspects of visual perception. The purpose of our study was to evaluate how implantation of multifocal (MF) and enhanced depth of focus (EDOF) intraocular lenses (IOLs) during cataract phacoemulsification can effect results of these tests. 

Setting

Department of Sensory Organ Studies, Collegium Medicum, Nicolaus Copernicus University, Bydgoszcz Poland, Oftalmika Eye Hospital, Bydgoszcz Poland, Department of Ophthalmology, Collegium Medicum,  Nicolaus Copernicus University, Bydgoszcz Poland

Methods

61 psychically and neurologically healthy patients after bilateral cataract removal were enrolled to the study. Patients were divided in three groups: group 1 where MF IOL was implanted to both eyes (22 patients), group 2 after bilateral EDOF IOL implantation (24 patients) and group 3 where EDOF lens was implanted to dominant eye and MF to the second eye (15 patients). 2-4 weeks after surgery of second eye each patient completed Motor Free Visual Perception Test (MVPT), Attention and Perceptiveness Test (APT) and Color Trial Test (CTT), (last two, in two different light conditions).

Results

The best average score of APT in good light conditions achieved patients from group 1: 689,6 marks comparing to 636,3 marks in group 2 and 616,2 marks in group 3. Similarly patients from group 1 had the best results of APT in poor light respectively: 517,6; 435,1 and  434,8 marks. The differences between group 1 and groups 2 and 3 were statistically significant (p≤0,05). Patients from group 1 completed the fastest task in CTT both in both good and poor light however differences were not significant. The results of MVPT were similar in all groups.

Conclusions

Bilateral implantation of MF IOL significantly improve the results of visual perception tests especially in poor light conditions. Psychologist performing visual perception evaluation should be aware that type of the IOL can influence the results of tests.
