Clinical research of phakic posterior chamber intraocular lens implantation for high myopia

目的 探讨有晶状体眼后房型人工晶状体（ICL）植入术治疗高度近视的临床效果.方法 对12例24眼接受ICL植入术的患者资料进行总结和分析,比较其手术前后最佳矫正视力、眼压及透明晶状体性状的改变.结果 12例24眼术后最佳矫正视力均达到或超过术前最佳矫正视力,改善了高度近视患者的视功能状况,术前眼压（14.26±2.13）mm Hg（1 mmHg=0.133 kPa）,术后1年眼压（14.79±2.77）mm Hg（P＞0.05）,术后眼压稳定,术后ICL与透明晶状体存在裂隙,随访期间未见并发性白内障、慢性色素膜炎等并发症.结论 ICL植入术治疗高度近视手术效果确切,预测性好,安全性高.

Objective To investigate the clinical efficacy and safety of phakic posterior chamber intraocular lens （ICL） implantation for high myopia. Methods Twenty-four eyes of 12 patients with high myopia were treated with ICL implantation. The best corrected visual acuity, intraocular pressure and lens changes shape between post-operative and pre-operative were compared. Results Successful implantations were done in all patients. All eyes had a significant increase in uncorrected visual acuity. Exactly improved visual function in patients with high myopia status. The intraocular pressure was （ 14.26 ± 2.13） mm Hg（1 mm Hg = 0.133 kPa） of pre-operative , and was （ 14.79 ± 2.77） mm Hg at 1 year after post-operative, the intraocular pressure was stability after the operation. UBM showed that there was a certain gap between ICL and the lens. During the follow-up period,no complications such as cataract,chronic uveal infusion were found. Conclusion Phakic posterior chamber ICL implantation is effective,safe and reliable method for the correction of high myopia.
