        Purposes : The effect on corneal swelling and curvature changes in the region of center and peripheral under wearing of therapeutic lenses on a daily and extended wear basis is analyzed. Methods : Thirty three college students(22.4±1.92 years old. 12 males and 21 femaJes) who consent to this clinical triaJ and have no ocuJar surgicaJ history and contact Jens complications were participated in clinical trial. Six therapeutic Jenses which are being prescribed most commonly in the clinic were fitted on the r ight eye(wear group) and no Jens fitted on the Jeft eye(control group). Each eye was examined after 8hours and 24 hours to compare cornea thickness and curvature changes. ln order to fit another Jens in turn. 48 hours interval at the !east was required and no other lenses were not allowed during trial Jens wear. Results : Comeal swelling induced by therapeutic soft contact Jens wear was significantly different in 8 hours(F=33.00. p=O.OO) and in 24 hours(F=38.83. p=O.OO). The degree of swelling in 8 hours of Jens wear was : A Jens(HENIA+ NV. WC : 38%. Dk/t : 7.86) 3.57±2.22%. D Jens(HEMA, WC : 55%. Dkft: 15.68) 3.18±2.05%. F Jens(HEMA+NVP, WC: 55%, Dk/t: 15.92) 2.79±1.61%. C Jens(Vifilcon A. WC: 55%, Dk/t : 23.88) 1.54±1.66%. B Jens(Ocufilcon D. WC: 55%. Dk/t : 26.85) -0.59±2.13%, E Jens(Lotrafilcon A. WC : 24%, Dk/t : 160.92) -0.70±1.53% in that order. The degree of swelling in 24 hours was : A Jens 8.50±3.71. D Jens 8.16±3.58%. F Jens 6.68±3.66%, C Jens 4.31±2.11%. B Jens 2.86±2.84%. E lens -0.03±1.97% respectiveJy. The order in 8 hours was ass that in 24 hours. Conclusions : Therefore. B Jens, C lens, E Jens are found to be more suitabJe for therapeutic Jens in this study. In case of A Jens, D Jens, F Jens which caused significant swelling, in order to confirm if those lenses are suitable for therapeutic Jens, further study on deswelling during day time after extended Jens wear is needed.
