ICL植入術(shù)對高度近視眼對比敏感度影響的研究
[Abstract]:Objective: to study the effect of posterior chamber intraocular lens (ICL) implantation on contrast sensitivity of high myopia. Methods: a total of 27 patients (52 eyes) with high myopia underwent ICL implantation. Contrast sensitivity (CS) values under the best corrected visual acuity (BCVA) of 1wk were measured by contrast sensitivity tester. The test was divided into four modes: visible vision, visible glare and dark glare. Five spatial frequencies were tested in each model. Results the paired t test was used for statistical analysis, and the difference was statistically significant (P 0.05). Results: the naked visual acuity of 1wk, 1mo and 3mo were 4.8558 鹵0.6960, 4.9519 鹵0.1513 and 4.8865 鹵0.5929 respectively after ICL implantation. The uncorrected visual acuity at 1 month after operation was significantly higher than that before operation (P 0.05). After operation, the spatial frequency of visual, dark, glare and dark glare in four modes were significantly higher than that before operation (P 0.05). Conclusion: the contrast sensitivity and visual function of high myopia were significantly improved after ICL implantation.
