目的:探讨四点式经巩膜缝线固定人工晶状体植入的临床应用及效果。方法:对20例20眼各种原因致后囊不完整的无晶状体眼及晶状体脱位患者行白内障手术联合四点式经巩膜缝线悬吊术植入四襻人工晶状体,其中一期植入15眼,二期植入5眼,随访2～6mo。结果:患者术眼术后裸眼视力和矫正视力均达到或超过术前矫正视力,其中0.2～者2眼(10%),0.5～者10眼(50%),≥1.0者7眼(35%),≤0.12者1眼(5%),术后患者人工晶状体位置均未发生偏移。结论:四点式经巩膜缝线固定的人工晶状体悬吊术是后囊不完整的无晶状体眼和晶状体脱位患者人工晶状体植入的一项有效措施,手术安全,术后并发症少,保证了最佳矫正视力。

AIM:To observe the result of four-point transscleral suture fixation of intraocular lens.METHODS:Totally 20 eyes in 20 cases with ruptured posterior capsule or no posterior capsule or lens displacement were performed cataract surgery with four-point transscleral suture fixation of intraocular lens.15 eyes of them were primarily implanted,5 eyes of them were secondarily implanted.They were followed up for 2-6 months.RESULTS:Of the 20 eyes,7 eyes(35%) had a corrected visual acuity of 1.0 or better.10 eyes(50%) had a corrected visual acuity of 0.5-<0.9.2 eyes(10%) had a corrected visual acuity of 0.2-<0.5.1 eye(5%) had a corrected visual acuity of 0.12 or worse.No IOL were decentered.CONCLUSION:Four-point transscleral suture fixation of intraocular lens is effective on IOL implantation in eyes with ruptured posterior capsule or no posterior capsule or lens displacement.It is safe,has fewer complications,and can ensure the best corrected visual acuity.
