目的探讨玻璃体切除术后无晶状体眼经巩膜睫状沟二期人工晶状体固定术的手术方法及技巧。方法对81例(81眼)玻璃体切除术后无玻璃体、无晶状体眼施行在前房灌注下后房多类型人工晶状体巩膜睫状沟缝线固定术,术后随访3月~9年,观察临床效果及术中术后并发症。结果81例术中一次固定成功,术后裸眼视力均较术前提高,最佳矫正视力均达到或接近术前最佳矫正视力。术中6例少量出血,术后少数患者出现一过性低眼压、再次外伤后襻折断、黄斑水肿、人工晶状体襻扭曲,光学面倾斜、视网膜脱离、眼内炎等并发症。结论玻璃体切除术后无晶状体眼二期人工晶状体缝线固定,术中应注意维持眼压,选择适合缝线固定的人工晶状体,可减少术中、术后并发症。
Objective To investigate the surgical methods and techniques of posterior stapler ciliary sulcus II vitrectomy for aphakia after vitrectomy. Methods Eighty-one eyes (81 eyes) with vitreous resection without vitreous body and phakia were treated by posterior chamber multiple scleral ciliary sulcus suture fixation. The patients were followed up for 3 months to 9 years after operation, Effect and intraoperative and postoperative complications. Results 81 cases were successfully fixed in one operation. The postoperative visual acuity of uncorrected visual acuity increased compared with that before operation. The best corrected visual acuity reached or approached the best corrected visual acuity before operation. A small amount of intraoperative bleeding in 6 cases, a small number of patients after a transient hypotony, traumatic fracture, macular edema, intraocular lens distortion, optical surface tilt, retinal detachment, endophthalmitis and other complications. Conclusions After vitrectomy, the second stage intraocular lens (IOL) is fixed with intraocular lens (IOL) fixation. Intraocular pressure should be maintained and the intraocular lens (IOL) suitable for suture fixation should be selected to reduce intraoperative and postoperative complications.
