The purpose of this study is to compare central foveal thickness (CFT) of patients preoperatively and postoperatively cataract surgery using SD- optical coherence tomography and to correlate CFT with vision.
MATERIALS AND METHODS
200 eyes of 100 patients were examined and two groups were formed. Group-A was considered as the control group in the study and eyes in group-B were operated for cataract using SICS technique. The central foveal thickness (CFT) in each group was measured using SD-OCT machine (Cirrus Zeiss) preoperatively, postoperatively on day 1, week 1 and after 1 month and the data was compiled and compared.
OCT detected increased central foveal thickness postoperatively on day 1 and weeks 2 but this returned to preoperative levels in one month. It was also seen that preoperative BCVA was poor (0.53± 0.12 Snellen approx. 6/24). Improvement in BCVA was seen in postoperative day-1, week 2 and 1 month.
This study shows that preoperative CFT values were minimal which increased on postoperatively but returned to preoperative values at one month after surgery BCVA was poorer preoperatively due to cataract but improved as CFT decreased with time
