目的探讨抗青光眼滤过术后的白内障超声乳化术的手术技巧及手术效果。方法避开功能性滤过泡,保持已有的滤过功能,对26例(28眼)抗青光眼滤过术后白内障行颞侧角巩膜隧道切口超声乳化折叠式人工晶体植入术,术后随访6个月~2 a,分析术后视力、眼压及并发症。结果 26眼术后视力均有不同程度的提高,≥0.6 17例(17眼),占60.72%;0.3~0.5的9例(9眼),占32.14%;≤0.1的2眼,占7.14%。平均眼压2.8 mm Hg,与术前比较差异无统计学意义(P>0.05)。功能性滤过泡未见明显疤痕化。结论青光眼滤过术后白内障采取颞侧角巩膜缘隧道切口超声乳化吸出术,可提高视力,同时保护滤过功能,强调对角膜内皮保护及防止术后高眼压。
Objective To investigate the surgical techniques and surgical effects of phacoemulsification after glaucoma filtration surgery. Methods 26 cases (28 eyes) of anti-glaucoma filtration cataract surgery were treated with phacoemulsification foldable intraocular lens implantation by intracisteal scleral tunnel incision. Follow-up 6 months ~ 2 a, analysis of postoperative visual acuity, intraocular pressure and complications. Results All the 26 eyes had postoperative visual acuity improved to some extent, ≥0.6 17 (17 eyes), accounting for 60.72%; 9 eyes (9 eyes) 0.3 ~ 0.5, accounting for 32.14%; eyes with ≤0.1 eyes accounting for 7.14% . Mean intraocular pressure 2.8 mm Hg, compared with the preoperative difference was not statistically significant (P> 0.05). Functional filtration bleb no obvious scarring. Conclusions Glaucoma filtering cataract surgery to take the lateral scleral tunnel incision phacoemulsification can improve visual acuity, while protecting the filtration function, emphasizing the protection of the corneal endothelium and prevent postoperative intraocular hypertension.
