Visual Quality of Cataract Patients with High Myopia After Implantation of Different Intraocular Lenses

N/AActive Not RecruitingNCT06892470

Wenzhou Medical University62 enrolled

Overview

This prospective study aims to compare the visual outcomes following the implantation of two different types of multifocal intraocular lenses (IOLs) in highly myopic patients. The study will evaluate visual quality, refractive outcomes, and patient satisfaction using various visual assessment techniques and subjective satisfaction surveys.

Outcomes

Primary Outcomes

Defocus Curve

The defocus curve is a tool used to assess visual acuity, particularly widely applied in evaluating the performance of presbyopia-correcting intraocular lenses (IOLs). Its principle involves placing a series of positive and negative lenses of varying diopters in front of the patient's eyes to simulate different distances from near to far, thereby assessing the patient's visual acuity (VA) at each simulated distance.

Time frame: Three months after operation

Visual Questionnaire

A visual questionnaire is a tool used to assess patients' visual function and quality of life. It typically includes a series of questions covering various aspects such as visual acuity at different distances (e.g., distance, intermediate, and near vision), dependency on glasses, and the impact of vision on the quality of life. By using a visual questionnaire, one can understand the actual visual experience and satisfaction of patients after the implantation of an intraocular lens.

Time frame: Three months after operation
