The endothelial cell count after phacoemulsification serves as a sensitive indicator for the level of corneal damage caused by different phacoemulsification techniques.
In a prospective and randomized study, the "Reversed Tip and Snip" technique and the "Divide and Conquer" technique were performed in groups of 30 patients each. The corneal endothelial cell count was measured preoperatively as well as 4 weeks and 3 months postoperatively.
The endothelial cell count showed significant (P < .001) reduction by approximately 10% after the "Reversed Tip and Snip" technique and by approximately 15% (P < .001) after the "Divide and Conquer" technique. The latter produced a significantly (P < .001) greater cell loss.
The "Reversed Tip and Snip" phacoemulsification technique produces less endothelial cell loss than the "Divide and Conquer" technique.
白内障超声乳化术后的内皮细胞计数是不同超声乳化技术所致角膜损伤程度的敏感指标。
在一项前瞻性随机研究中，分别对30例患者实施“翻转头端与剪切”技术和“分而治之”技术。术前以及术后4周和3个月测量角膜内皮细胞计数。
“翻转头端与剪切”技术后内皮细胞计数显著降低（P <.001），约降低10%；“分而治之”技术后内皮细胞计数显著降低（P <.001），约降低15%。后者导致的细胞损失显著更大（P <.001）。
“翻转头端与剪切”超声乳化技术比“分而治之”技术导致的内皮细胞损失更少。
