摘要
40只成老年兔眼晶体分别行超声乳化术、普通囊外摘除术摘除,借助显微仪进行详细观察。探讨了角膜损伤机制、设计和改进了手术步骤,提出了预防和减少角膜损伤措施。
40 rabbits are used to study the effects of phaco-emulsification and extracap-sular lens removal or; corneal endothelial cells and corneal thickness.With the specular microscope, the preoperative cell morphology, cell density and thickness of cornea are revealed. The endothelial cell counts decrease 16% (at central) and 14% (at the periphery) after the surgery with phaco-emulsification and 25% (central) and 22% (periphery) with extracapsular lens removal. Corneal thickness increases in both groups. Scanning electron microscopy shows some alterations in morphology of endothelial cell injury significantly different in the 2 groups. According to these results the causes of corneal thickness increasing and mechanism of endothelial cell injury are approached and a new procedure preventing the cell injury and decreasing cornea edema in both groups is designed.
