To evaluate the influence of the cataract surgery on the subfoveal choroidal thichness (SCT).
A total of 71 eyes of 54 patients were evaluated. SCT was measured prior to cataract surgery and at 1 day, 1 week, 1 month and 3 months postoperatively. Phacoemulsification with intraocular lens (IOL) implantation was performed to all 71 eyes. Spectral domain optical coherence tomography with enhanced depth imaging (EDI-OCT) was performed to measure SCT using a Cirrus® HD OCT (Carl Zeiss Meditec). EDI-OCT images were scanned by 5 trained technicians and SCT was measured by a single examiner using calipers equipped on OCT machine. SCT was defined as the distance from the posterior edge of the retinal pigment epithelium to the choroid/sclera junction.
The average SCT was 217.2µm preoperatively, 213.9µm at 1 day post-operatively (post-op), 217.9µm at 1 week post-op, 219.4µm at 1 month post-op and 220.4µm at 3 month post-op. There were no significant differences between time points of SCT measurement.
The SCT had not significantly changed either before or after phacoemulsification with IOL implantation.
