Intumescent or hypermature cataracts make a safe capsulorhexis impossible. High frequency capsulotomy represents a satisfying solution for this problem. Primary goal of the present study was to investigate a possible damage to the corneal endothelium by this method.
55 patients with an uncomplicated senile cataract were enclosed into a prospective randomized study undergoing cataract surgery with capsulorhexis or with high frequency capsulotomy. Corneal endothelium was examined preoperatively as well as postoperatively at several intervals.
Concerning loss of endothelial cells and parameters of polymegatism and pleomorphism there were no statistically significant differences between both groups.
The diathermy during high frequency capsulotomy does not show any clinically relevant negative effects on the corneal endothelium within cataract surgery.
膨胀期或过熟期白内障无法进行安全的连续环形撕囊。高频囊切开术是解决该问题的一种令人满意的方法。本研究的主要目的是调查该方法对角膜内皮可能造成的损伤。
55例单纯老年性白内障患者纳入一项前瞻性随机研究，接受连续环形撕囊或高频囊切开术的白内障手术。术前及术后在多个时间点检查角膜内皮。
两组在内皮细胞丢失以及大小不均一性和多形性参数方面无统计学显著差异。
白内障手术中高频囊切开术期间的透热疗法对角膜内皮未显示出任何临床相关的负面影响。
