【摘要】：目的探讨应用前段玻璃体切割、囊袋拉钩联合Cionni改良张力环(Cionni-modified capsular tension ring,MCTR)在伴有前房玻璃体脱出的外伤性晶状体半脱位手术中的有效性和安全性。方法伴有前房玻璃体脱出的外伤性晶状体半脱位患者16例(16眼),脱位范围在90°~120°7眼、120°~180°5眼、180°~270°4眼,其中合并虹膜根部离断3眼、express植入1眼、青光眼瓣膜阀植入1眼。根据前房玻璃体情况,行曲安奈德染色后经前房或睫状体平坦部行玻璃体切割术,连续环形撕囊后使用2~4个囊袋拉钩钩住撕囊边缘,稳定晶状体囊袋并使其居中,超声乳化白内障吸出、MCTR植入及巩膜层间缝合固定,晶状体囊袋内植入折叠人工晶状体(intraocular lens,IOL)。术后随访3个月,观察术后视力、术中术后并发症、前囊口、IOL位置、眼压情况。结果所有患者均顺利完成白内障吸出、MCTR及IOL植入;其中植入双钩MCTR 7眼,单钩9眼。术后视力0.5者9眼,0.3~0.5者4眼,0.1~0.3者2眼,≤0.1者1眼,术后术眼最佳矫正视力与术前比较,差异有统计学意义(χ2=17.503,P=0.000)。Pantacam眼前段分析系统获得Scheimpflug图像分析IOL居中性好,无MCTR及IOL移位等并发症发生。术中术后并发症有皮质残留、房水后部返流综合征、前囊撕裂、前囊口收缩、后囊膜混浊等。结论有效前房或睫状体平坦部玻璃体切割是减少手术并发症的关键,前段玻璃体切割、囊袋拉钩联合Cionni张力环植入是伴有前房玻璃体脱出的外伤性晶状体不全脱位较理想的术式选择。
[Abstract]:Objective to evaluate the efficacy and safety of anterior vitrectomy bag retractor combined with Cionni modified tension loop (Cionni-modified capsular tension ring,MCTR) in traumatic lens subluxation with anterior chamber vitreous prolapse. Methods Sixteen cases (16 eyes) of traumatic lens subluxation with anterior chamber vitreous prolapse were included. The range of dislocation was 90 掳~ 120 掳7 eyes, 120 掳~ 180 掳5 eyes, 180 掳~ 270 掳4 eyes, including 3 eyes with iridotomy, 1 eye with express implantation and 1 eye with glaucoma valve implantation. According to the vitreous condition of anterior chamber, the anterior chamber was stained with triamcinolone acetonide and vitrectomy was performed through the anterior chamber or the flat part of the ciliary body. After continuous circular capsulorhexis, 2 ~ 4 bag retractor was used to hold the edge of the capsular tear, to stabilize and center the lens capsular bag. Phacoemulsification cataract extraction, MCTR implantation and scleral interlaminar suture fixation, intraocular lens (intraocular lens,IOL) implantation in the capsular bag. Postoperative visual acuity, postoperative complications, anterior capsule orifice, IOL location and intraocular pressure were observed after 3 months follow-up. Results all patients successfully completed cataract aspiration, MCTR and IOL implantation, including 7 eyes with double hook MCTR and 9 eyes with single hook. The postoperative visual acuity was 0.5 in 9 eyes, 0.3 in 4 eyes, 0.3 in 2 eyes, and 鈮，
