Abstract

During a four-week postoperative course, the central and peripheral corneal thicknesses of 23 intracapsular cataract extraction cases (only one case by extracapsular) were measured with the Mishima-Hedbys modification of the Haag-Streit Corneal Pachometer. The results were as follows: 1. Before surgery, the mean of the average central corneal thickness was 0.52 +/- 0.02(S.D.)mm in central part and 0.64 +/- 0.03mm in peripheral part. 2. During 2~3 postoperative days, the central corneal thickness was increased highly and its mean thickness was 0.70 +/- 0.08mm (34.6% increment), and there after the corneal thickness was found to be decreasing to the mean value of 0.53 +/- 0.03mm on 17~20 postoperative days which there was no significant difference from original thickness (P>0.05). 3. Peripheral corneal thickness also increased slightly (0.75 +/- 0.04mm, 14%increment) on 2-3 postoperative days and there after the peripheral thickness was gradually decreased to the original thickness up to 12~13 postoperative days (0.66 +/- 0.04mm, P>0.05) which reveals much earlier improvement than that of the central corneal thickness (17~20 POD).
