【摘要】：目的：探讨同切口青光眼白内障联合手术对角膜源性散光的影响。方法：对30例32眼青光眼合并白内障患者行同切口白内障囊外摘除人工晶体植入联合小梁切除手术。采用电脑验光曲率仪测量术前,及术后3天、1周、1月、3月的角膜曲率的变化。结果：术后3天散光度为3.09±0.59D达最大,以逆规性散光为主,与术前相比,差异有统计学意义(P0.01)。1周后散光度为1.75±0.58D仍以逆规性散光为主,与术前相比,差异有统计学意义(P0.01)。3月时散光度为0.73±0.22D以顺规性散光为主,较术前差异无统计学意义(P0.05)。结论：同切口青白联合手术术后早期可产生较大的散光,但大多数患者的角膜散光度可随时间的延长而逐渐减少,3月基本与术前相当。
[Abstract]:Objective: to investigate the effect of combined cataract surgery with the same incision on corneal astigmatism. Methods: thirty cases (32 eyes) of glaucoma complicated with cataract were treated with intraocular lens implantation and trabeculectomy with the same incision. And the changes of corneal curvature 3 days after operation, 1 week, 1 month and 3 months after operation. Results: the maximum astigmatism was 3.09 卤0.59D on the 3rd day after operation, and the main astigmatism was inverse astigmatism. The difference was statistically significant compared with that before operation. The astigmatism of 1.75 卤0.58D was still the reverse astigmatism after 1 week compared with that before operation. The astigmatism of 0.73 卤0.22D was mainly regular astigmatism at 3 months, which had no statistical significance compared with that before operation. Conclusion: large astigmatism can be produced in the early stage of combined operation with the same incision, but the corneal astigmatism of most of the patients can decrease gradually with the prolongation of time, and the astigmatism of the cornea in 3 months is almost the same as that before operation.
