目的:探讨准分子激光治疗性切削术(PTK)联合个性化光学角膜切削术(PRK)治疗炎性角膜翳的适应证、检查方法、手术要点和临床效果。方法:6例角膜翳患者,术前行眼前节、角膜地形图、角膜厚度、眼压等详细检查;2例既往正视者行PTK+个性化PRK治疗,4例合并屈光不正者行PTK+个性化PRK+普通PRK治疗。结果:视力≥1.0者2例,0.9者1例,0.8者2例,0.7者1例。屈光状态:等值球镜±0.5D者3例;+0.75D者1例;-0.75D者2例。角膜透明度:4例完全透明,2例残留角膜云翳。并发症:1例术后2个月复查时眼压升高7.2mmHg,经对症处理恢复正常。全部病例术后未见其他并发症或不良反应。结论:PTK联合个性化PRK是治疗角膜翳安全实用、经济便捷、疗效肯定的治疗方式,只要对象合适,术式合理,操作得当,可达到事半功倍的临床效果,可供临床选用。
Objective: To investigate the indications, examination methods, operative points and clinical effects of excimer laser photocoagulation (PTK) combined with personalized optical keratotomy (PRK) for the treatment of inflammatory cornea. Methods: Six cases of corneal pterygium were examined with preoperative anterior segment, corneal topography, corneal thickness and intraocular pressure. PTK + personalized PRK was treated in 2 cases and PTK + individualized in 4 cases with ametropia PRK + ordinary PRK treatment. Results: Visual acuity ≥ 1.0 in 2 cases, 0.9 in 1 case, 0.8 in 2 cases, 0.7 in 1 case. Refractive status: equivalent sphere ± 0.5D in 3 cases; + 0.75D in 1 case; -0.75D in 2 cases. Corneal transparency: 4 cases were completely transparent, 2 cases of residual corneal nebula. Complications: 1 case 2 months after the review IOP increased 7.2mmHg, symptomatic treatment returned to normal. All cases no other complications or adverse reactions. Conclusions: PTK combined with personalized PRK is a safe and practical method for the treatment of cornea 经. It is economical and convenient and has a definite curative effect. As long as the target is suitable, the operation method is reasonable and the operation is proper, the clinical effect can be achieved with a multiplier effect.
