简要总结
The Best Way to Improve the Near Visual Acuity After ZXR00 IOL Implantation
详细描述
ZXR00 intraocular lens is a new type of IOL that can achieve good continuous visual acuity. Its characteristic is to improve the distance and intermedia visual acuity and maintain good visual quality while sacrificing the near visual acuity. Previous studies report that there are mainly two ways to improve the near visual acuity of ZXR00：1.Bilateral implantation of ZXR00 with micromonovision. 2. Combined Implantation of ZXR00 and multifocal IOLs.This study aim to explore which is the best way to improve the near visual acuity after ZXR00 IOL implantation.

结局指标
主要结局
Uncorrected Visual Acuities
时间窗: 2022.12.31
Uncorrected monocular and binocular visual acuities (logarithm of the minimum angle of resolution) at distance (5m), intermediate(66 cm), and near (40 cm).
Patient satisfaction
时间窗: 2022.12.31
Patient satisfaction was rated on a scale of 1 to 5: 1 = very dissatisfied; 2 = dissatisfied; 3 = neutral; 4 = satisfied; and 5 = very satisfied.
Subjective quality of vision
时间窗: 2022.12.31
Subjective quality of vision was evaluated using the 14-item Visual Function Questionnaire (VFQ-14).Each item was scaled according to the degree of difficulty of different activities: 4 points (no difficulty), 3 points (a little difficulty), 2 points (a moderate amount of difficulty), 1 point (a great deal of difficulty), and 0 point (unable to do the activity).overall score is range 0-56.The higher the score, the worse subjective quality of vision.
Adverse visual symptoms
时间窗: 2022.12.31
Adverse visual symptoms including blurred vision, glare, starbursts, haloes, hazy vision, distortion, focusing diffculties, multiple images, and depth perception diffculty, was evaluated using the Quality of Vision test. This test includes 30 items, with a score between 0 and 3 (overall score range 0-90).The higher the score, the more postoperative adverse visual symptoms.
Corrected Visual Acuities
时间窗: 2022.12.31
Corrected monocular and binocular visual acuities (logarithm of the minimum angle of resolution) at distance (5m), intermediate(66 cm), and near (40 cm).
Stereopsis
时间窗: 2022.12.31
Stereopsis was evaluated using OCULUS Binoptometer.
Defocus Curve
时间窗: 2022.12.31
Corrected monocular and binocular defocus curves were measured from +2.5 D to -4.0 D (in 0.5 D steps).
