作者用Q开关钕-YAG激光(Coherent 9900型)对22例25眼开角型青光眼作了房角手术。所选病例为常规眼内滤过性手术后,用大量药物控制不理想和氩激光小梁成形术(ALT)后的患者。激光治疗前,作全面眼科检查,包括视力、眼压、房角和眼压描记。Q开关钕-YAG激光能量为10±0.2mJ。局麻后,安放一特殊涂膜的Trokel接触镜,选择最容易看到房角的象限给予治疗。若所有象限均可看到,则选下部房角作治疗。用氦-
The authors performed atrial keratoplasty in 22 patients with 25 open-angle glaucoma using a Q-Switched Neodymium-YAG laser (Coherent Model 9900). The patients selected were those who had undergone extensive intraocular filtration surgery and underwent poor medical control with argon laser trabeculoplasty (ALT). Before laser treatment, make a complete eye examination, including visual acuity, intraocular pressure, angle and tachycardia. Q switch Nd-YAG laser energy is 10 ± 0.2mJ. After local anesthesia, place a special coating of Trokel contact lenses, select the most easily see the quadrant of the corner to give treatment. If all the quadrants can be seen, choose the lower part of the angle for treatment. With helium -
