【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,P0.05)。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,P0.05)。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。
[Abstract]:Objective to investigate the operative method and effect of scleral flap fixation with posterior chamber foldable intraocular lens (IOL). Methods 22 patients (22 eyes) were treated with scleral flap transscleral fixed posterior chamber foldable intraocular lens implantation. The preoperative and postoperative visual acuity and best corrected visual acuity were recorded and followed up for more than 12 months. The effect of operation and postoperative complications were observed. Results the preoperative best corrected visual acuity (BCVA) was 0.58 卤0.24 in 22 eyes, and the postoperative visual acuity was improved. The uncorrected visual acuity was 0.52 卤0.27 at 1 week postoperatively, and there was no significant difference between the preoperative best corrected visual acuity and the preoperative best corrected visual acuity (BCVA). The best corrected visual acuity was 0.61 卤0.23 at 1 month postoperatively, and there was no significant difference between the two groups at 1 week after operation. The intraocular pressure increased in 1 eye and then decreased to normal in 1 eye. Corneal edema gradually subsided within 3 days. No intraocular lens displacement, dislocation and tilt, no seams, no iris adhesion, macular edema and other complications occurred. Conclusion Transscleral fixation of posterior chamber intraocular lens implantation with scleral flap has the advantages of good recovery of visual acuity and low incidence of postoperative complications. It is safe and effective for refraction correction of aphakic eyes without posterior capsule or with insufficient posterior capsule support.
