简要总结
The investigators are going to Investigate the comparative efficacy of the patients who underwent cataract surgery with three different multifocal IOLs.
详细描述
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.

结局指标
主要结局
Postoperative contrast sensitivity in the three groups.
时间窗: Postoperative 3 months
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
Postoperative uncorrected near, intermediate, and far visual acuity.
时间窗: At 1month and 3months after surgery
logMAR
Postoperative satisfaction questionnaire.
时间窗: Postoperative 3 months
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.
次要结局
- Postoperative refractive outcome(Postoperative 3 months)
