To evaluate epithelial debridement for the treatment of persistent hyperopia in eyes that had photorefractive keratectomy (PRK).
Optimax Laser Eye Clinics, Manchester, London, Bristol, England.
Epithelial debridement was performed on 46 eyes to reduce the hypermetropia following excimer laser PRK.
Mean age of the patients was 43 years +/- 9.7 (SD). Mean refractive change was -0.51 diopter (D) +/- 0.76 (range +0.75 to -2.50 D). Mean change in best corrected visual acuity (BCVA) was 0.00 Logmar units (range +0.40 to -0.20 units), although 33% of eyes lost one line or more of Logmar BCVA. Mean follow-up after debridement was 61.0 +/- 26.9 weeks (range 26 to 140 weeks).
Epithelial debridement is an unpredictable procedure to treat secondary hyperopia after PRK, producing a small mean change in spherical equivalent with a wide range of results. A significant number of eyes lost one line or more of Logmar BCVA. We therefore do not advocate epithelial debridement after PRK.
评估上皮清创术治疗接受过准分子激光角膜切削术（PRK）的眼睛持续性远视的效果。
英国曼彻斯特、伦敦、布里斯托尔的Optimax激光眼科诊所。
对46只眼睛进行上皮清创术以减轻准分子激光PRK术后的远视。
患者的平均年龄为43岁±9.7（标准差）。平均屈光变化为-0.51屈光度（D）±0.76（范围为+0.75至-2.50 D）。最佳矫正视力（BCVA）的平均变化为0.00 Logmar单位（范围为+0.40至-0.20单位），尽管33%的眼睛Logmar BCVA下降了一行或更多。清创术后的平均随访时间为61.0±26.9周（范围为26至140周）。
上皮清创术是治疗PRK术后继发性远视的一种不可预测的方法，等效球镜度平均变化较小，结果范围广泛。相当数量的眼睛Logmar BCVA下降了一行或更多。因此，我们不主张在PRK术后进行上皮清创术。
