The Best Way to Improve the Near Visual Acuity After ZXR00 IOL Implantation

Uncorrected Visual Acuities

Uncorrected monocular and binocular visual acuities (logarithm of the minimum angle of resolution) at distance (5m), intermediate(66 cm), and near (40 cm).

Corrected Visual Acuities

Corrected monocular and binocular visual acuities (logarithm of the minimum angle of resolution) at distance (5m), intermediate(66 cm), and near (40 cm).

Defocus Curve

Corrected monocular and binocular defocus curves were measured from +2.5 D to -4.0 D (in 0.5 D steps).

Patient satisfaction

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

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

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.
