摘　　要：目的探讨无巩膜瓣经巩膜缝线固定后房折叠型人工晶状体植入术的手术方法及效果。方法对22例(22眼)行无巩膜瓣经巩膜固定后房折叠型人工晶状体植入术,记录术前和术后的裸眼视力及最佳矫正视力并随访超过12个月,探讨该手术方法的技巧,观察手术效果及术后并发症。结果 22眼术前最佳矫正视力为0.58±0.24,术后视力均有提高。术后1周裸眼视力0.52±0.27,与术前最佳矫正视力相比,差异无统计学意义(t=0.742,P>0.05)。术后1个月最佳矫正视力0.61±0.23,与术后1周相比,差异无统计学意义(t=0.814,P>0.05)。术后1眼出现眼压升高,1d后降至正常;1眼出现角膜水肿,3d内逐渐消退。未见人工晶状体移位、脱位及倾斜,无缝线脱落及暴露,无虹膜粘连、黄斑水肿等并发症发生。结论无巩膜瓣经巩膜固定后房型人工晶状体植入术具有视力恢复良好、术后并发症发生率低等优势,对于无后囊或后囊支撑力不足的无晶状体眼的屈光矫正是安全有效的。Objective To study the surgery and effects of posterior chamber foldable intraocular lens implantation through scleral fixation without scleral flap. Methods Twenty-two eyes of 22 patients received posterior chamber foldable intraocular lens implantation through scleral fixation without flap were enrolled, and the uncorrected visual acuity （UCVA） and best corrected visual acuity （BCVA） before and after operation were recorded, the follow-up time was 12 months, the effects of the technique and complications were observed. Results Preoperative BCVA was 0.58 ± 0.24, postoperative visual acuity all improved. Preoperative UCVA at 1 week was 0.52 ± 0.27, no significant difference was found between preoperative BCVA and postoperative UCVA （ t = 0.742 ,P 〉 0.05 ）. Postoperative BCVA was 0.61 _＋ 0.23 at 1 month, no significant difference was found between postoperative 1 month and 1 week（ t = 0. 814,P 0.05）. Intraocuiar pressure increased in 1 eye after surgery, and decreased to normal level after 1 day. Corneal edema occurred in 1 eye and subsided gradually in next 3 days. There was no complication such as displacement, dislocation and tilt of intraocular lens, suture shedding and exposure, adhesion of iris and macular edema. Conclusion Posterior chamber foldable intraocular lens implantation through scleral fixation without scleral flap have the advantages of short time,small incision and low incidence of complications, it is safe and effective for refractive aphakic eye with no or insufficient posterior capsular support.
