摘要

报告一例倾斜的无缝线巩膜内固定人工晶体,强调使用 23 号激光加强触觉和视觉交界处的管理。 病例报告。 一名 27 岁的男子因左眼外伤性白内障接受治疗。他接受了玻璃体旁切除术、晶状体切除术、眼膜剥离术和眼帽切除术,未出现并发症。术后五天,他出现了眼压过高,最终需要在左眼植入艾哈迈德青光眼瓣膜。初次手术 16 个月后,患者采用 Yamane 技术在左眼进行了 CT Lucia 602 人工晶体二次植入术。术后第二天,患者出现晶状体明显倾斜。三周后,患者接受了人工晶体复位手术。操纵触觉装置对人工晶体复位无效。手术切除了颞部硬膜,并使用 23 号探针激光照射两个光学触觉交界处,同时用光导管固定晶状体。倾斜得到了矫正,随访一年后,视力提高到了 20/40。 使用 23 号激光在触觉和光学交界处进行加固,可以成功地将倾斜的无缝线巩膜内固定人工晶体重新定位。可以考虑在植入时进行这种激光,作为一种预防性方法,以减轻倾斜并降低再次手术的风险。

Laser of the Haptic-Optic Junction to Fix a Tilted Yamane Intrascleral-Fixated Lens
To report a case of tilted sutureless intrascleral fixated IOL, emphasizing its management with 23-gauge laser to strengthen the haptic-optic junction. Case report. A 27-year-old man was referred for treatment of traumatic cataracts in his left eye. He underwent pars plana vitrectomy, lensectomy, membrane peel, and capsulectomy without complications. Five days after the surgery, he developed ocular hypertension that ultimately required insertion of an Ahmed glaucoma valve in the left eye. 16 months after the initial procedure, the patient underwent secondary lens implantation with a CT Lucia 602 IOL in the left eye using the Yamane technique. The day following surgery, the patient presented with a significantly tilted lens. Three weeks later, the patient underwent surgery for IOL repositioning. The manipulation of the haptics was ineffective in repositioning the IOL. The temporal sclerotomy was removed and a 23-gauge probe was used to laser both optic-haptic junctions while a light pipe held the lens in place. The tilt was corrected, and visual acuity improved to 20/40 at one year follow-up. Successful repositioning of tilted sutureless intrascleral fixated IOLs can be achieved using 23-gauge laser reinforcement at the haptic-optic junction. Consideration could be made to perform this laser at the time of implantation as a prophylactic approach to mitigate tilt and reduce the risk of reoperation.
