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.
