摘要
目的观察有晶状体眼后房型人工晶状体（PC—PRL）植入矫正高度近视的临床疗效。方法回顾性系列病例研究。选择2011年1月至2012年5月间行PC．PRL矫正高度近视患者25例（45眼）。术后随访6～17月，平均（10．9＋1．6）个月，应用配对t检验分析手术前后裸眼视力、眼压、角膜内皮细胞计数及前房深度，分析并发症的发生情况。结果术后裸眼视力4．5～5．2，好于术前最佳矫正视力者35眼（78％）。术后平均眼压（13．7±4．2）mmHg，与术前（13．9±4．1）mmHg比较，差异无统计学意义。术后平均角膜内皮细胞计数（2609±296）cells／mm2，与术前（2818±327）cells／ramz比较，差异无统计学意义。术后的平均拱高稳定，为（0．380±0．135）mm，未见人工晶状体与自身晶状体贴近或接触。结论PC—PRL植入矫正高度近视临床疗效确切，具有良好的安全性，是高度近视患者的理想治疗方法。
Objective To observe the clinical effect of PC-PRL （phakic refractive lens） implants to correct high myopia. Methods This was a retrospective case series study. Twenty-five patients （45 eyes） with high myopia were implanted with PC-PRLs from January 2011 to May 2012. The postoperative follow-up period was 6 to 17 months （average 10.9＋1.6 months）. A paired-sample t test was used to analyze uncorrected visual acuity, intraocular pressure, endothelial cell density, anterior chamber depth, and the occurrence of complications was recorded. Results Uncorrected visual acuity （UCVA） 4.5-5.2 was better than preoperative best corrected visual acuity （BCAV） for 35 eyes （78%）. The mean postoperative IOP was 13.7±4.2 mmHg, which was not a statistically significant difference from the mean preoperative lOP （13.9±4.1 mmHg）. The mean postoperative endothelial cell density was （2609±296）cells/mm2, which was not a statistically significant difference from the mean preoperative endothelial cell density（2818±327）eells/mm2. The stability of PC-PRLs was high, average high arch was （0.380±0.135）mm, and there were no artificial crystals close to crystal position. Conclusion PC-PRL implantation to correct high myopia is effective and safe and is the ideal treatment for patients with high myopia.
