摘要/Abstract

摘要： 当代准分子激光手术包括板层切削手术和表层切削手术,表层切削手术的优点在于无瓣相关并发症、术后生物力学较稳定,但有术后疼痛明显、角膜上皮下雾状混浊(haze)、糖皮质激素需要使用时间长、屈光回退等不足。表层切削手术主要有TransPRK、LASEK、Epi-LASIK PRK,其中TransPRK真正实现无接触操作,上皮和基质切削一步到位,以其更精确的切削而被广泛看好。如今表层手术渐有回归的趋势,其术后疼痛、haze、屈光回退是三个需要重点讨论的问题。

Abstract: Contemporary excimer laser surgery includes both stoma and surface cutting surgeries. The advantages of surface cutting surgery are stable postoperative biomechanics and no flap related complications. However, the disadvantages include postoperative pain, haze under the corneal epithelium, long term use of glucocorticoids, and refractive regression. Surface cutting operations include photorefractive keratectomy(PRK), TransPRK, laser-assisted sub-epithelial keratectomy(LASEK), and Epi-laser assisted in-situ keratomileusis(Epi-LASIK). Of these, TransPRK is a truly contactless operation and involves only one set of epithelial and matrix cutting. The procedure is widely favored due to the ability to make more accurate cuts. Complications such as postoperative pain, haze, and retractive regression are the three most common complications after surface cutting surgery.

Key words: Excimer laser surface cutting surgery, TransPRK, Pain, haze, Refractive regression
