经上皮准分子激光屈光性角膜切削术(TransPRK)是一种新型角膜表层屈光手术,采用治疗屈光性角膜切削术(PTK)模式在角膜表面用激光切削一个预先设定的非球面形状,随后附加一定厚度的激光板层切削,整个切削过程除上皮和屈光切削一步完成,最后戴软性角膜接触镜保护创面.其优点是激光切削更加精确、有效缩短手术时间、无需负压吸引,真正实现了无接触式的角膜表层手术.但目前此手术开展较少,仍需继续研究并完善.

The development of surface ablation as the treatment of refractive errors mostly focus on the epithelial removal techniques.TransPRK is a kind of new developed surface refractive surgery.TransPRK uses the phototherapeutic keratectomy (PTK) mode to ablate epithelium in preset aspherical shape,then the stromal ablation is immediately performed,epithelial and stromal ablation are in one step,finally,a soft contact lens is placed on the cornea at the completion of the procedure.The advantages of this surgery are more accurate,shorter operation time,no suction pressure,truly achieved" no-touch" surface ablation.The shortage of surgery is the limited development; we need further research and refinement.This review recommends the developing history,principle,operative process,clinical effect and advantages of the TransPRK.
