Ov앉night Orthokeratology 콘핵트렌즈 착용자 28명 (56안}을 대상으로 각막두께의 변화률 분삭하가 위하여 Optical Coherence Tomography와 Orbscan Pachymetry System올 이용하여 렌즈 착용 전과 렌즈 착용 1 개월 후의 각막중심부 두께를 측정하였다. Ortho-K 콘택트렌즈률 착용하기 전 Optical Coherence Tomography와 Orbscan Pachymetrγ System으로 측정한 각막중심부 두째는 517.7 :t 33.4 /ßII와 530.4 :t 42.1 /ßII로 Orbscan Pachymetrγ Sys따n으로 측정 한 값야 12.7 μm 정 도 더 두꺼 웠고(t = 7.01, p = O.αxx>>， 푸 측정값 사이에 높은 상관판계가 있었다(OCT 측정값= 112.8 + 0.71없4 x OPS 측정값; r == 0.96, p < O.α)()1).

To evaluate the change of comeal thickness after wearing OI당lokeratology contact lenses, the central comeal thickness was measured at baseline and 1 rnonth 따ter W많ring contact lens using Opti떠1 Coherence Tomograhy and Orbscan Pachymetry System. πle 않ntral comeal thickness measured by ()Ptical Coherence Tornography and Orbscan Pachymetry System at baseline were 517.3 :t 33.4 f.lIll 때d 530.4:t 42.1 f.lIll resκ~tively, and the mean of two diff，앉‘ent measurements showed statistically significant difference(p = O.αXX)()). The central comeal thickness measured by Optic머 Coh얹"ence Tomograhy and Orbscan Pachymetry System were highly correlated(OCT measurem얹Jts = 112.8 + 0.7'κ34 x OPS measurements). The central comeal thickness at 1 month after wearing Orthokeratology contact lens measured by Optical Coherence Topography and Orbscan Pachymetry System were reduced by 14.9 :t 9.3 μm 없d 8.5 :t 15.6 f.lIIl res야:x::tively. There were no significant ch없1ge of cenσal comeal thickness measured by two different systems. After wearing the orthokeratology contact lenses for one month, the mid-p퍼pheraI com얹1 thickness measured by Orbscan Pachymetry Syst없1 showed significantly thicker of 14 때 than those of baseline.
