目的评价无缝线切口二期后房型人工晶状体植入术的疗效。方法对 ２２眼无晶状体眼患者分别采用３．５ ｍｍ（Ａ组 １０眼）及 ５．５ ｍｍ（Ｂ组 １２眼）的反眉状巩膜隧道切口，二期植入 ６ ｍｍ折叠式丙烯酸脂类及一体式 ＰＭＭＡ后房型人工晶状体，并与同期 １２眼６ ｍｍ常规角膜缘切口（Ｃ组），二期 ６ ｍｍ一体式 ＰＭＭＡ后房型人工晶状体植人对比。结果随访 ３～１５个月，无缝线切口组术后矫正视力均优于及等于术前最佳矫正视力，其中≥０．５者 Ａ组 ９眼（９０％），Ｂ组 ９眼（７５％）。缝线切口组，术后矫正视力优于及等于术前最佳矫正视力１０眼（８３． ５％）， ≥０．５者７眼（５８．３％）。结论采用无缝线切口二期后房型人工晶状体植人可明显降低角膜散光，减轻术后炎症反应及增加手术的安全性，是矫正无晶状体眼屈光不正的一种较理想的方法。
Objective To evaluate the effect of posterior chamber intraocular lens implantation in the second stage of seamless incision. Methods In 22 patients with aphakia, 3.5 mm (group A, 10 eyes) and 5.5 mm (group B, 12 eyes) of the eyebrow scleral tunnel incision were implanted. In the second stage, 6 mm folded acrylics And one-piece PMMA posterior chamber intraocular lens (IOL), and compared with 12 eyes of 6 mm conventional limbal incision (C group) and 6 mm one-piece PMMA posterior chamber intraocular lens implantation in the same period. Results The follow-up of 3 to 15 months showed that the corrected visual acuity was superior to and equal to the best corrected visual acuity in the group of sutureless incision, including 9 eyes (90%) in group A and 9 eyes (75 eyes) in group B %). Suture group, postoperative corrected visual acuity was better than or equal to preoperative best corrected visual acuity in 10 eyes (83.5%), ≥ 0.5 in 7 eyes (58.3%). Conclusion The use of sutureless incision posterior chamber intraocular lens implantation can significantly reduce corneal astigmatism, reduce postoperative inflammatory response and increase the safety of surgery, is a correction of aphakic eye refractive errors is a more ideal method.
