晶体核脱入后玻璃体内可意外地发生于白内障手术中,尤其是在高度近视、玻璃体液化和硬核的白内障眼。可引起青光眼、视网膜脱离和晶体过敏性眼内炎等术后并发症。为此,应将脱位的晶体物质、尤其是核清除。 介绍两种摘除脱位晶体核的方法:①用生理盐水冲洗玻璃体腔或暂时先关闭切口,待核浮起,再用圈套器经角膜缘切口摘出。②将软核用晶体和玻璃体切割方法粉并碎吸出。硬核则用切割器械吸起并送入前房,再通过角膜缘切用口圈套器摘出。
Intraocular detachment of crystalline nuclei can occur unexpectedly in cataract surgery, especially in highly myopic, vitreous liquefaction and hard nucleus cataract. Can cause glaucoma, retinal detachment and crystal allergic endophthalmitis and other postoperative complications. To this end, the dislocation of crystalline material, especially the nuclear clearance. Describe two methods of removal of dislocation of the crystal nucleus: ① flush with saline or vitreous chamber for the time being to close the incision, until the nuclei float, and then use the snare limbal incision excision. ② the soft nuclei and vitreous cut method powder and broken sucked out. Hardcore is used to pick up the cutting device and into the anterior chamber, and then cut through the corneal margin with a cuff removed.
