目的观察有晶状体眼后房型人工晶状体植入术后视觉对比敏感度的变化.方法前瞻性临床病例研究.对2010年3月至2012年6月在武警陕西省总队医院眼科就诊的高度近视患者29例共55只眼,实施有晶状体眼后房型人工晶状体植入手术.观察患者术前及术后1、4、12、24周视力和屈光度等变化,对术前与术后24周对比敏感度进行比较.结果所有手术眼裸眼视力明显提高.术后24周裸眼视力≥1.0的眼数较术前最佳矫正视力≥1.0增加4只眼,并有34只眼(61.8％,34/55)裸眼视力高于术前最佳矫正视力.术后24周患者对比敏感度在明视环境下,6、18c/d空间频率段较术前明显提高,差异有统计学意义(P＜0.05);在暗视和暗视眩光环境下,12、18c/d空间频率段与术前比较均明显提高,差异有统计学意义(P＜0.05).结论高度近视患者实施有晶状体眼后房型人工晶状体植入手术,能明显提高不同亮度环境下,中、高空间频率段的对比敏感度,改善视觉质量.

Objective To evaluate the contrast sensitivity after implanting the posterior chamber phakic intraocular lens.Methods Twenty-nine patients (55 eyes) received posterior chamber phakic intraocular lens implantation.Visual acuity,refraction and the contrast sensitivity were examined before twenty-four weeks after the operation.Results After the surgery all of the patients had a higher uncorrected visual acuity (UCVA).Twenty-four weeks after the operation there were 4 eyes (7.3％) with the UCVA≥ 1.0 more than the eyes with the best corrected visual acuity (BCVA) ≥ 1.0preoperatively.After surgery the UCVA of 34 eyes (61.8％) was better than the best corrected visual acuity (BCVA) before surgery.Twenty-four weeks after the surgery,in bright condition,the contrast sensitivity in 6 and 18 c/d were significantly improved (P ＜0.05).In dark and glare conditions,the contrast sensitivity in 12 and 18 c/d were significantly improved (P ＜0.05).Conclusions The implantation of posterior chamber phakic intraocular lens in high myopica can improve the contrast sensitivity in high c/d in any light condition,and also imprvoe the visual quality.
