Abstract

To report and assess a new technique of phacoemulsification with capsular tension ring (CTR), supracapsular intra-scleral haptic fixation (ISHF), and optic capture in eyes with progressive subluxations and to assess stability of capsular bag-CTR-IOL optic complex. Cases with progressive subluxation first underwent phacoemulsification with CTR implantation. Supracapsular ISHF in the form of glued IOL was then performed by externalizing the haptics through a plane below the iris and above the anterior capsule via sub-flap sclerotomies created 180 degrees apart as for glued IOL. Intra-scleral haptic tuck together with optic capture of the supracapsular glued IOL was then performed. Patients were followed up for safety and stability. Five patients underwent surgery successfully. All had more than one quadrant subluxation. All eyes had well-centered IOL with adequate haptic tuck and no significant tilt. Optic capture was successful in all. Uncorrected distance visual acuity (DVA) improved from 0.18 ± 0.18 to 0.65 ± 0.36, and spectacle-corrected DVA improved from 0.59 ± 0.33 to 0.83 ± 0.24. Post-operative intraocular pressure was 17 ± 3.08, and there was no evidence of any uveitis at the 1-month visit. The anterior capsule opacified around the captured optic; however, the bag continued to remain expanded with stable IOL centration at 1-year follow-up. Phacoemulsification with CTR followed by supracapsular ISHF with optic capture is a viable technique for progressive subluxations. This technique spares the vitreous cavity thus decreasing the risk of posterior segment complications. It expands and immobilizes the capsular bag-CTR-IOL optic complex and has shown good results at 1-year follow-up.

摘要

报告并评估一种用于晶状体进行性半脱位眼的白内障超声乳化吸除联合囊袋张力环(CTR)、囊上巩膜内触觉固定(ISHF)及光学部捕获技术,并评估囊袋-CTR-人工晶状体光学部复合体的稳定性。晶状体进行性半脱位的病例首先行白内障超声乳化吸除联合CTR植入术。然后通过在虹膜下方、前囊膜上方的平面,经相距180度的巩膜瓣下切口将触觉襻引出,以粘贴式人工晶状体的形式进行囊上ISHF。接着进行巩膜内触觉襻折叠及囊上粘贴式人工晶状体的光学部捕获。对患者进行安全性和稳定性随访。5例患者手术成功。所有患者均有超过一个象限的晶状体半脱位。所有术眼人工晶状体均居中良好,触觉襻折叠充分,无明显倾斜。所有患者光学部捕获均成功。未矫正远视力(DVA)从0.18±0.18提高至0.65±0.36,眼镜矫正DVA从0.59±0.33提高至0.83±0.24。术后眼压为17±3.08,术后1个月时无葡萄膜炎迹象。捕获的光学部周围前囊膜发生混浊;然而,在1年随访时,囊袋仍保持扩张,人工晶状体居中稳定。白内障超声乳化吸除联合CTR,随后行囊上ISHF及光学部捕获是治疗晶状体进行性半脱位的一种可行技术。该技术避免了玻璃体腔操作,从而降低了后节并发症的风险。它可扩张并固定囊袋-CTR-人工晶状体光学部复合体,且在1年随访时显示出良好效果。
