目的:Pentacam眼前节全景分析仪观察高度近视眼植入后房型有晶状体眼人工晶状体(implantable collamer lens,ICL,STAAR公司,瑞士)后眼前节的改变。方法:收集我院2009-10/2010-02高度近视眼行ICL植入手术患者8例12眼。术后随访平均3.8mo。Pentacam眼前节全景分析仪对术前、术后前房深度、ICL拱高等参数进行测量,同时记录术前、术后裸眼视力,最佳矫正视力等数据。结果:术前前房深度3.01～3.46(平均3.24±0.11)mm,术后3mo时,前房深度2.01～2.67(平均2.39±0.18)mm,拱高0.34～0.74(平均0.52±0.11)mm,ICL与透明晶状体等其他周围组织没有接触,没有引起房角关闭。术后3mo,UCVA与术前BCVA比较,有统计学差异(t=2.237,P=0.047)。未发现白内障、黄斑囊样水肿、视网膜脱离等严重并发症。结论:ICL术后前房变浅,但与正常晶状体之间拥有安全的间隙。ICL植入治疗高度近视眼安全、有效。

AIM:To observe the changes of anterior segment after implantation of the implantable collamer lens(ICL)for high myopia by Pentacam anterior segment system.METHODS:Eight patients 12 eyes with myopia were implanted ICL in our hospital from October 2009 to February 2010.The mean follow-up was 3.8 months.UCVA,BCVA,intraocular pressure,spherical equivalent(SE) were measured.ICL position was observed by Pentacam.Anterior chamber depth was observed.RESULTS:The postoperative UCVA was better than the BCVA of preoperative(t=2.237,P=0.047).Following up 3 months,the vault was 0.34-0.74mm(average 0.52±0.11mm),the average depth of anterior chamber was 2.39±0.18(2.01-2.67)mm was less than that of preoperative which was 3.24±0.11(3.01-3.46) mm.There were no serious complications.CONCLUSION:ICL implantation is a safe,efficacy,predictable and stable method in correcting high myopia.
