目的探讨小梁切除术后硬核白内障透明角膜切口冷超乳摘除对角膜切口、散光和角膜内皮细胞数量及形态的影响。方法对连续小梁切除术后Ⅳ级硬核白内障手术患者随机分组,试验组采用透明角膜切口白内障冷超乳摘除,对照组采用透明角膜切口普通超声乳化技术。比较两组术后视力、角膜切口水肿、手术源性散光、角膜内皮细胞数量和形态改变。结果两组术后视力恢复和手术源性散光差异无统计学意义(P>0.05);角膜切口水肿和角膜内皮细胞数量减少对照组高于试验组,角膜内皮六角形细胞比例试验组好于对照组,差异有统计学意义(P<0.05)。结论透明角膜切口冷超乳摘除小梁切除术后硬核白内障对角膜损伤较小,手术安全性较高,是小梁切除术后硬核白内障手术摘除较为理想的术式选择。
Objective To investigate the effect of clear corneal incision cold phacoemulsification on corneal incision, astigmatism and corneal endothelial cell number and morphology after trabeculectomy. Methods The patients with grade Ⅳ cataract surgery undergoing continuous trabeculectomy were randomly divided into two groups. The experimental group was treated with clear corneal incision cold phacoemulsification and the control group was treated by clear corneal incision common phacoemulsification. Visual acuity, corneal incision edema, surgical astigmatism, corneal endothelial cell number and morphological changes were compared between the two groups. Results There was no significant difference between the two groups in visual acuity recovery and surgical astigmatism (P> 0.05). Corneal incision edema and corneal endothelial cell number decreased in the control group and in the corneal endothelial hexagonal cell ratio test group Group, the difference was statistically significant (P <0.05). Conclusions Transparent corneal incision cold phacoemulsification trabeculectomy after traumatic cataract has less corneal damage and higher operative safety. It is an ideal surgical choice for surgical removal of hard cataract after trabeculectomy.
