Measurement of Subfoveal Choroidal Thickness After Cataract Surgery in Enhanced Depth Imaging Optical Coherence Tomography

RESULTS. The 95 patients had a mean age of 76 6 8.3 years. The mean SFCT at baseline was 224 6 75 lm. It showed a negative correlation with age and axial length (P ¼ 0.03). The SFCT significantly increased after surgery with a mean value of 232 6 76 l ma t D1 (P < 0.001), 237 6 78 l ma t M1 (P < 0.001), and 232 6 76 l ma t M3 (P < 0.001). The mean CRT increased from 234 6 48 lm at baseline to 248 6 48 l ma t M1 (P ¼ 0.005), and 252 6 81 l ma t M3 (P ¼ 0.001). Three (2.6%) patients developed a pseudophakic cystoid macular edema (PCME). The greatest progression of SFCT after phacoemulsification was observed for these patients. It preceded the occurrence of pseudophakic cystoid macular edema (PCME) by 1 month. CONCLUSIONS. Mean SFCT increased after cataract surgery. The changes in baseline SFCT were greater in PCME patients and preceded the increase in CRT.
