目的 :探讨抗青光眼滤过术后白内障患者进行白内障超声乳化吸除及人工晶状体植入术的手术切口选择和临床效果。方法 :32例 (4 1只眼 )抗青光眼滤过术后的白内障患者 ,采用上方透明角膜隧道切口和避开滤过泡的巩膜隧道切口行白内障超声乳化吸除 ,植入折叠式人工晶状体 2 4只眼 ,硬性人工晶状体 17只眼。结果 :全部白内障术后病例视力有不同程度的提高 ,视力≥ 0 5者达 75 6 %。采用透明角膜隧道切口和巩膜隧道切口术后患者的眼压和滤过泡改变无差异性 ,术后随访平均 5个月 ,平均眼压较术前增加 1 5 9mmHg(1mmHg =0 133kPa) ,差异无显著性。结论 :对抗青光眼滤过术后白内障患者 ,采用透明角膜和巩膜隧道切口行白内障超声乳化吸除及人工晶状体植入术 ,可提高视力 ,同时可保持原有的滤过功能。
Objective: To investigate the surgical incision selection and clinical effect of cataract phacoemulsification and intraocular lens implantation in cataract patients after glaucoma filtration surgery. Methods: Thirty-two (41 eyes) patients with cataract after glaucoma filtration surgery were treated with phacoemulsification and scleral tunnel incision with clear corneal upper incision and scleral tunnel bypass to avoid filtering bleb, then foldable intraocular lens 2 4 eyes, 17 eyes of rigid intraocular lens. Results: The visual acuity of all cataract patients increased to some extent, and the visual acuity ≥ 0.5 was 75.6%. The intraocular pressure (IOP) and filtration bleb changes were no difference after using clear corneal tunnel incision and scleral tunnel incision. The average follow-up time was 5 months after operation. The mean intraocular pressure was increased by 159.9 mmHg (1 mmHg = 0,133 kPa) No significant. Conclusion: To combat glaucoma after cataract surgery, the use of clear corneal and scleral tunnel incision cataract phacoemulsification and intraocular lens implantation, can improve visual acuity, while maintaining the original filtration function.
