Samsung Medical Center60 enrolled

Overview

The investigators are going to Investigate the comparative efficacy of the patients who underwent cataract surgery with three different multifocal IOLs.

Going to analyze the clinical results of 60 patients who underwent bilateral cataract surgery and multifocal IOL implantation. The patients were divided into the following three groups: Mix-and-Match, EDOF, and Trifocal. The clinical assessments included uncorrected near, intermediate, distance and best corrected distance visual acuity, defocus curves, contrast sensitivity, and reading speed. Patient satisfaction was evaluated by questionnaire. All outcomes were compared among the three groups.

Outcomes

Primary Outcomes

Postoperative uncorrected near, intermediate, and far visual acuity.

logMAR

Time frame: At 1month and 3months after surgery

Postoperative contrast sensitivity in the three groups.

3, 6, 12, and 18 cycles per degree using a CSV-1000 chart (Vector Vision, reenville, OH) under photopic (85 cd/m2), mesopic (\~3 cd/m2), and mesopic with glare conditions

Time frame: Postoperative 3 months

Postoperative satisfaction questionnaire.

patients were shown images and asked to rate the frequency, degree, and discomfort related to the visual artifacts as none, minimal, moderate, or severe (0, 1, 2, or 3 points for the respective levels). The mean score was calculated.

Time frame: Postoperative 3 months

Secondary Outcomes
