To describe a case of choroidal neovascularization (CNV) following photorefractive keratectomy (PRK) to correct myopia.
We performed PRK in both eyes of a 20-year-old girl to correct myopia. Refractive error was -4.75 -2.25 × 5 in the right eye and -5.00 -1.25 × 180 in the left eye. Metamorphopsia was noticed by the patient in the right eye one month after the surgical procedure. The patient was referred 3 months later when visual loss happened.
Fluorescein angiography and Optical Coherence Tomography (OCT) were performed which were compatible with CNV. After three monthly intravitreal bevacizumab injections, sub-retinal hemorrhage and intraretinal fluid resolved, but subretinal scar remained without any visual acuity improvement.
It seems that CNV may occur after PRK in myopic eyes. Also, refractive surgeons should consider CNV development in cases with visual compliant or metamorphopsia following PRK.
描述一例准分子激光原位角膜磨镶术（PRK）矫正近视后发生脉络膜新生血管（CNV）的病例。
我们对一名20岁女孩的双眼进行PRK以矫正近视。右眼屈光不正为-4.75 -2.25×5，左眼为-5.00 -1.25×180。术后1个月患者右眼出现视物变形。3个月后视力下降时患者前来就诊。
进行了荧光素血管造影和光学相干断层扫描（OCT），结果与CNV相符。每月一次玻璃体内注射贝伐单抗3次后，视网膜下出血和视网膜内液消失，但视网膜下瘢痕仍存在，视力无改善。
近视眼中PRK后似乎可能发生CNV。此外，屈光手术医生在PRK后出现视力异常或视物变形的病例中应考虑CNV的发生。
