초록

목적: 각막 굴절교정수술방법에 따른 술 후 안압 변화에 차이가 있는지 알아 보고자 하였다. 대상과 방법: 라식(LASIK, Laser in-situ keratomileusis), 인트라 라식(Intra-LASIK), 라섹(LASEK, Laser assisted sub-epithelial keratomileusis)수술을 시행받은 환자를 대상으로 의무기록을 후향적으로 분석하였다. 술 후 안압, 안압 변화량, 중심각막두께에 따른 안압 분포를 비교하였다. 결과: 수술 방법에 따른 술 전 굴절이상, 각막 절제량에는 차이가 없었으나, 술 전 안압과, 술 전 중심각막두께에 따른 차이는 있었다(p＜0.05). 세 군간 술 후 3개월째 안압, 안압 변화량은 차이를 보이지 않았다(p＞0.05). 각막 절제량에 따른 술 후 안압 변화량과 술 후 중심각막 두께에 따른 안압 분포는 세 군 모두 양의 상관관계를 보였으나 세 군간 차이는 없었다(p＞0.05). 결론: 비접촉안압계로 측정한 각막 굴절교정수술 후 안압은 중심각막두께에 따라 양의 상관관계를 보였으나, 수술 방법에 따른 세 군간 뚜렷한 차이는 보이지 않았다.

Abstract

Purpose: To evaluate differences in intraocular pressure change after three different methods of corneal refractive surgery. Methods: The medical records of 296 eyes of 150 patients who underwent corneal refractive surgery were reviewed. Spherical equivalent, central corneal thickness (CCT), and intraocular pressure before surgery, and one month, three months and six months after surgery were analyzed. Results: The patients included those having undergone laser-assisted in situ keratomileusis (LASIK; 96 eyes), IntraLASIK (98 eyes), laser assisted sub-epithelial keratomileusis (LASEK; 102 eyes). Post operative intraocular pressure in ablated corneal depth and in CCT showed a meaningful correlation. Intraocular pressure decreased significantly after refractive surgery; however, there were no differences among the three groups. Conclusions: Post operative intraocular pressure after corneal refractive surgery is influenced by CCT. There were no differences in intraocular pressure change among the three groups.
