目的 :探讨复杂无晶状体眼的二期后房型人工晶状体植入术的方法和效果。方法 :对 4 6例 5 3只眼伴有不同程度眼前段结构紊乱、前房玻璃体疝、后囊膜缺损、玻璃体切除术后的复杂无晶状体眼患者 ,联合行眼前段重建、前段玻璃体切除、人工晶状体缝线固定等术式及二期植入后房型人工晶状体。术后随访 5～ 18个月。结果 :术后裸眼视力均达到或优于术前矫正视力 ,其中术后裸眼视力≥ 0 3者 4 5只眼 (84 9% )。术后瞳孔圆者 4 2只眼 ,人工晶状体正位者 4 8只眼 ,4只眼稍偏位 ,仅 1只眼人工晶状体倾斜。结论 :复杂无晶状体眼的二期后房型人工晶状体植入术可取得满意效果 ,熟练的操作技巧和使用高质量粘弹剂是手术成功的关键 Objective: To explore the method and effect of posterior chamber intraocular lens implantation in complex aphakia. Methods: 46 patients with 53 eyes with varying degrees of anterior segment disorder, anterior chamber vitreous hernia, posterior capsule defect, vitrectomy complicated aphakia patients, combined anterior segment reconstruction, anterior vitrectomy, Intraocular lens suture fixation and other surgical procedures and two implantation of posterior chamber intraocular lens. The patients were followed up for 5 to 18 months. Results: The uncorrected visual acuity reached or exceeded the preoperative corrected visual acuity. Among them, the uncorrected visual acuity of ≥ 0 3 was 45% (84 9%). Postoperative pupil round 42 eyes, intraocular lens in 48 eyes, 4 eyes slightly offset, only one eye inclined intraocular lens. CONCLUSIONS: Secondary posterior chamber intraocular lens implantation with complex aphakia achieves satisfactory results, and proficient operating skills and the use of high quality viscoelastic agents are key to successful surgery
