前节OCT辅助下PTK联合PRK治疗屈光不正伴角膜斑翳一例

Anterior segment OCT-assisted PTK combined with PRK in the treatment of myopia associated with cornea macula:a case report

患者为26岁近视眼女性,右眼裸眼视力为0.1,左眼为0.2;左眼角膜有外伤史,鼻侧遗留角膜斑翳。经术前充分检查,右眼行飞秒激光辅助的准分子激光原位角膜磨镶术,左眼行准分子激光治疗性角膜切削术联合准分子激光角膜表面切削术。术后3个月患者双眼UCVA为1.2,左眼角膜瘢痕大部分消除。

Nowadays,myopia morbidity keeps increasing in China.As the improvements of technique and safety in corneal refractive surgeries,an increasing number of patients with refractive error tend to choose these treatments.The 26-year-old woman with myopia in this case,whose UCVA was 0.1 in OD and 0.2 in OS,had corneal macula in the nasal side of the left eye owing to a corneal trauma occurred more than 10 years ago.After sufficient preoperative examinations,FS-LASIK was performed on the right eye and PTK combined with PRK was performed on the left eye.The UCVA was 1.2 in both eyes 3 months postoperatively,and the corneal macula was mostly cleared in the left eye.It is demonstrated that PTK combined with PRK is an effective and safe way to correct the diopter as well as remove the lesions for the lowly or moderately myopic patients accompanied with superficial corneal opacity.
