目的:观察和评估传导性角膜成形术(CK)对缓解老视症状的有效性、稳定性、安全性。方法:对64例有老视症状患者1眼行CK治疗以改善近视力,对其中38例伴轻度远视者另一眼同时手术治疗以提高远视力,共治疗102眼。结果:术后6月97%的患者双眼裸眼远视力达0.8,近视力达0.33(J4)或更好,89%的视近眼MRSE与目标屈光度相差在±1.00D以内,术后4～6月有82%眼的MRSE变化在0.5D以内,术后6个月87%的患者满意或非常满意。结论:早期临床观察证实,CK手术矫治老视具有操作简单,见效快,安全性高,并发症少等优点,不失为有用的手术矫正方法。
Objective: To observe and evaluate the effectiveness, stability and safety of conductive keratoplasty (CK) in alleviating the symptoms of presbyopia. Methods: 64 patients with presbyopia were treated with CK to improve near vision. One of 38 patients with mild hyperopia and the other with simultaneous surgery to improve distant vision were treated with 102 eyes. Results: After 6 months, 97% of the patients had uncorrected visual acuity of 0.8, near vision of 0.33 (J4) or better, 89% of the near-eye MRSE and the target diopter within ± 1.00D, and from April to June 82% of the MRSE changes within 0.5D within 6 months after 87% of patients satisfied or very satisfied. Conclusion: The early clinical observation confirmed that CK surgery for presbyopia has the advantages of simple operation, quick response, high safety and few complications, which may be a useful surgical correction.
