【摘要】：目的:研究有晶状体眼后房型人工晶状体(ICL)植入术对高度近视眼对比敏感度的影响。方法:选择行ICL植入术的高度近视眼患者27例52眼,用对比敏感度测试仪分别测试术前及术后1wk最佳矫正视力下的对比敏感度值。测试分为明视、明视眩光、暗视、暗视眩光四种模式,每种模式测试1.5,3,6,12,18c/deg五个空间频率。结果采用配对t检验进行统计学分析,以P0.05表示差异有统计学意义。结果:ICL植入术后1wk裸眼视力4.8558±0.6960,术后1mo裸眼视力4.9519±0.1513,术后3mo裸眼视力4.8865±0.5929。术后1wk;1,3mo裸眼视力较术前裸眼视力均明显提高(P0.05)。术后明视、暗视、明视眩光、暗视眩光四种模式下空间频率为1.5,3,6,12,18c/deg对比敏感度值较术前均有明显提高(P0.05)。结论:高度近视眼植入ICL后对比敏感度较术前明显提高,视功能得到显著改善。
[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 卤0.6960, 4.9519 卤0.1513 and 4.8865 卤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.
