Abstract 액시머레이저 굴절교정각막절제술 후의 각막상피 장벽기능의 변화를 알아보고자 근시 교정을 위해 시술 받은 21명(남:여=8:13)의 25안을 대상으로 술후 I, 2, 3주에 각각 형광측정법 (fluorophotonietry)을 이용하여 각막상피 투과도를 측정하고, 이와 함께 각막상피 재생기간을 측정하였다. Sodium fluorescein에 대한 각막상피 투과성은 술후 증가하였다가 2주째에 정상 상태로 회복되었다. 상피 치유일에 따른 투과성의 차이는 유의하지 않았다(P>0.05). 교정 듯수 6 디옵터를 기준으로 두 군으로 나누어 비교하였던 경우에 상피 투과도의 변화도는 통계적으로 유의한 차이가 없었다(P>0.05). 이러한 결과에서 액시머레이저 굴철교정각막절제술은 각막상피 장벽기능의 완전한 재생을 지연시키며, 손상된 장벽기능은 술후 2주에는 회복된다고 하겠다. 그러므로, 적어도 술후 첫 2주간은 각막상피에 영향을 줄 수 있는 투약이나 처치에는 세심한 주의를 하는 것이 필요하다(한안지 39:1119-1124, 1998). We used the fluorophotometry to investigate the corneal epithelial barrier function after excimer laser photorefractive keratectomy (PRK). Twenty-five eyes of 21 subjects (13 women, 8 men) underwent PRK to correct rnyopia. Corneal epithelial healing time was measured and corneal epithelial permeability to sodiurn fluorescein was evaluated by fluorophotoinetry at I, 2, and 3 weeks after surgery. The corneal epithelial permeability increased significantly 1 week after surgery and returned to preoperative level 2 weeks after surgery. The permeability differences according to epithelial healing days and corrected diopters were not statistically significant(p>0. 05). These results suggest that PRK delays complete reconstruction of corneal epithelial barrier function. The corneal epithelium regained its functional barrier 2 weeks after PRK in patients, so, at least, during the first 2 weeks, care should be taken to miniinize further epithelial trauma from topical inedication or surgical manipulation (J Korean Ophthalm이 Soc 39 : 1119-1124, 1998) .
