目的评价白内障超声乳化摘除+前段玻璃体切割术及二期阀门管植入术治疗碱性化学伤导致的白内障及继发青光眼的疗效,并对具体操作做一介绍。方法2003年1月～12月我院收治的病程3个月以上,因眼部碱性化学伤继发白内障及青光眼的患者共11例12眼。一期先行白内障超声乳化摘除和前段玻璃体切割术,术后药物控制眼压。术后1个月内施行二期阀门管植入术。随访3～8个月,观察手术并发症、眼压和视功能等情况。结果所有患者术后眼压均能迅速控制。术后1周,眼压在9～16mmHg之间,平均(11.1±4.3)mmHg。视功能得到不同程度的改善。未见顽固性葡萄膜炎反应、视网膜脱离等并发症。结论分阶段行白内障超声乳化摘除和前段玻璃体切割术及阀门管植入术治疗碱性化学伤导致的继发性青光眼和白内障效果良好,为进一步行穿透性角膜移植手术创造条件。
Objective To evaluate the efficacy of cataract phacoemulsification combined with anterior vitrectomy and second-stage valve implantation in the treatment of cataract and secondary glaucoma caused by alkaline chemical injury and to introduce the specific operation. Methods January 2003 to December in our hospital for more than 3 months duration of treatment, eye alkaline chemical injury secondary to cataract and glaucoma in 11 patients with 12 eyes. A phacoemulsification cataract extraction and anterior vitrectomy, postoperative drug control intraocular pressure. Within 1 month after the implementation of two valve tube implantation. Followed up for 3 to 8 months, observed complications, intraocular pressure and visual function. Results All patients with intraocular pressure can be quickly controlled. One week after operation, IOP ranged from 9 to 16 mmHg, with an average of (11.1 ± 4.3) mmHg. Visual function has been improved to varying degrees. No intractable uveitis reaction, retinal detachment and other complications. Conclusions Phacoemulsification and phacoemulsification and valve tube implantation in phased cataract surgery are effective in treating secondary glaucoma and cataract caused by alkaline chemical injury, which will create the conditions for further penetrating keratoplasty.
