目的探讨青光眼术后白内障不同手术方式角膜内皮细胞密度的变化。方法将58例(58眼)青光眼术后白内障患者分为两组。A组采用透明角膜切口超声乳化术;B组采用颞侧巩膜隧道切口非超声乳化术。分别观察两组术前及术后的角膜内皮细胞密度。结果术后3个月角膜内皮细胞密度:A组(2004±152)个/mm2,B组(1825±191)个/mm2,二者比较差异无统计学意义(P>0.05)。结论两种手术方式对角膜内皮损害基本相同。
Objective To investigate the changes of corneal endothelial cell density in different surgical methods of cataract surgery after glaucoma surgery. Methods 58 cases (58 eyes) of glaucoma patients with cataract were divided into two groups. Group A was treated with clear corneal incision phacoemulsification; Group B was treated with temporal scleral tunnel incision non-phacoemulsification. The corneal endothelial cell density was observed before and after operation respectively. Results The density of corneal endothelial cells at 3 months after operation was significantly lower in group A than in group A (2004 ± 152) / mm 2 and group B (1825 ± 191) / mm 2 respectively. There was no significant difference between the two groups (P> 0.05). Conclusion The two surgical methods have the same damage to corneal endothelium.
