目的 评价单纯老年性白内障组、闭角型青光眼小梁切除术后白内障组、糖尿病视网膜病变眼底氩离子激光术后白内障组超声乳化术后角膜内皮细胞损失率。方法 设三个对照组。第一组单纯老年性白内障患者 4 0例 4 6眼 ,第二组闭角型青光眼小梁切除术后白内障患者 36例 38眼 ,第三组糖尿病视网膜病变眼底氩离子激光术后白内障患者 38例 4 0眼。应用相同超声能量、相同吸力、相同灌注液行白内障超声乳化术后三组间角膜内皮损失率。结果 第一组角膜内皮细胞损失低于第二组、第三组。结论 青光眼组和糖尿病组的角膜“愈合储备”明显低于单纯白内障组 ,所以对青光眼和糖尿病人在超声乳化手术前应特别注意角膜内皮功能状况 ,手术操作时应格外谨慎 ,尽可能减少损失。
Objective To evaluate the loss rate of corneal endothelial cells after phacoemulsification in cataract patients with cataract in the group of senile cataract and cataract after angle-closure glaucoma and diabetic retinopathy. Methods Three control groups. The first group of 40 cases of elderly patients with cataract 40 cases of 46 eyes, the second group of angle-closure glaucoma after cataract surgery in 36 cases 38 cases, the third group of diabetic retinopathy of argon ion laser postoperative cataract patients 38 cases 40 eyes. With the same ultrasonic energy, the same suction, the same perfusion fluid cataract phacoemulsification three groups of corneal endothelial loss rate. Results The corneal endothelial cell loss in the first group was lower than that in the second and third groups. Conclusion The corneal “healing reserve” of glaucoma and diabetic patients is significantly lower than that of plain cataract patients. Therefore, special attention should be paid to the functional status of corneal endothelium before glaucoma and diabetes patients should be operated on. The operation should be performed with caution to minimize the loss.
