Extracapsular cataract extractions and posterior chamber intraocular lens implantations combined with glaucoma filtering procedures were done in 47 eyes of 43 consecutive patients who had coexisting cataract and glaucoma. A limbal-based conjunctival flap was used in 22 patients and a fornix-based flap was used in 25 patients; the surgical technique was otherwise identical in all patients. Patients were followed up for a minimum of six months (mean, 18 months). Long-term intraocular pressure control and visual acuity were similar in the two groups, although the limbal-based group had significantly better early postoperative intraocular pressure control. Because control of intraocular pressure during the early postoperative period is a principal benefit of combined cataract and glaucoma surgery, we prefer the limbal-based conjunctival flap.
对43例患有白内障合并青光眼的连续患者的47只眼进行了囊外白内障摘除术、后房型人工晶状体植入术联合青光眼滤过手术。22例患者采用了以角膜缘为基底的结膜瓣，25例患者采用了以穹窿为基底的结膜瓣；所有患者的手术技术在其他方面相同。对患者进行了至少6个月（平均18个月）的随访。两组患者的长期眼压控制和视力相似，尽管以角膜缘为基底的结膜瓣组术后早期眼压控制明显更好。由于术后早期眼压控制是白内障与青光眼联合手术的主要益处，因此我们更倾向于采用以角膜缘为基底的结膜瓣。
