Objective To investigate the effect of clear corneal incision phacoemulsification of 3. 0 mm in different positions after cataract with trabeculectomy. Methods Thirty — seven cataract patients (44 eyes) with trabeculectomy received clear corneal incision phacoemulsification of 3.0 mm in different positions. They were divided into two groups according to the incision, the above temple incision group (group A, n =27) and above incision group (group B, n = 10). The intraocular pressure, corneal curvature and corneal endothelial cells in the two groups were observed. Results The intraocular pressure in the two groups showed a trend of ascending at first and descending at last, while the corneal curvature and corneal endothelial cells showed a trend of descending at first and ascending at last. There were no significant differences in intraocular pressure, corneal curvature, and corneal endothelial cells in the two groups in the final follow— up. Conclusion The clear corneal incision phacoemulsification of 3.0 mm in both incisions above temple and the above incision after trabeculectomy have curative effect, and we can follow the principle of individual selection.%目的 探讨小梁切除术后白内障采用不同位置透明角膜切口超声乳化术的疗效.方法 对小梁切除术后的白内障患者37例(44眼)行不同位置3.0 mm透明角膜切口超声乳化术,按照切口位置不同分为颞上方切口组(A组)27例(30眼)和上方切口组(B组)10例(14眼).术后观察2组患者的眼压、角膜曲率、角膜内皮细胞数等指标.结果 术后2组患者眼压呈先上升后下降的趋势,角膜曲率及角膜内皮细胞计数呈先下降后上升的趋势,但2组末次随访时眼压、角膜曲率及角膜内皮细胞计数方面差异无统计学意义(P＞0.05).结论 小梁切除术后白内障患者接受透明角膜切口超声乳化术颞上方和上方切口均疗效确切,可遵循个体化原则选用.
