Quality of life evaluation after phacoemulsification with four types of intraocular lenses

Introduction
In recent years, many new intraocular lens (IOL) models have been designed. The implantation of multifocal IOLs brings many benefits in certain groups of patients, however, it may also be associated with side effects. The aim of the study was to assess quality of life in patients who underwent bilateral phacoemulsification and received one of four different IOL models in both eyes.

Material and methods
The study consisted of 100 patients after phacoemulsification with binocular implantation of various IOLs: either extended depth of focus IOL (Tecnis Symfony, group 1, n = 20), multifocal IOL (Diffractiva-aA, group 2, n = 30), bifocal IOL (Diffractiva-aA Bi, group 3, n = 25) or a monofocal IOL (Aspira-aA, group 4, n = 25), who met the inclusion criteria. All patients were operated using standard phacoemulsification, pre- and postoperative care was the same.

Results
Satisfaction was the highest in groups 2 and 4, slightly lower in group 1 and the lowest in group 3. Patients from group 3, 2, and 4 worried about their eyesight most often, while patients from group 1 were the least concerned.

Conclusions
Undesirable optical phenomena occurred most often in patients with a multifocal IOL, were less severe in patients with EDoF and bifocal IOL and were the least frequent in patients with a monofocal IOL. The majority of patients from all groups were highly satisfied with their eyesight after cataract surgery, although a slightly lower percentage was observed in patients with monofocal IOLs. The percentage of patients who would undergo the surgery with the same lens again was very high and similar in all groups. The quality of life was the highest in patients with multifocal and monofocal IOLs, it was lower in patients with an EDoF IOL and it was the worst in patients with a bifocal IOL.
