Comparative study of the function and visual quality with VFQ 25 between a monofocal plus lens (biconvex, continuous focus, high-order aspheric anterior surface: eyhance) and a standard monofocal lens.

Abstract

Introduction. The decrease in visual acuity secondary to cataracts in elderly people has a significant impact on quality of life. Cataract surgery is the only treatment to resolve the problem and consists of removing the cloudy lens and implanting an intraocular lens. It has recently been demonstrated that new models of multifocal intraocular lenses implanted during cataract surgery reduce dependence on air lenses when performing activities requiring distance, intermediate, and near vision. However, multifocal intraocular lenses have drawbacks, such as causing dysphotopsia, which can lead to patient dissatisfaction and even the need to remove the intraocular lens. There are monofocal plus lenses that do not cause dysphotopsia and improve distance and intermediate visual acuity, achieving patient satisfaction.

Methodology. A prospective, longitudinal, comparative study of a deliberate intervention in routine clinical practice will be conducted. Patients who were candidates for intraocular lens implantation and who did not have other underlying ocular pathologies and who required cataract phacoemulsification surgery plus intraocular lens implantation will be recruited. Postoperative VFQ-25 questionnaire results were evaluated and compared using the following parameters: near visual acuity, intermediate visual acuity, distance visual acuity, and contrast sensitivity. Statistical analysis was performed using a general analysis of variance model with covariates adjustment.

Objective. The objective of this study is to evaluate patients' satisfaction with their quality of life in relation to visual performance associated with monofocal plus intraocular lens implantation, assessed using the VFQ-25 questionnaire

Results. The protocol is in the recruitment phase.
