Materials and Methods: We retrospectively analyzed, 42 eyes of 42 patients who underwent uncomplicated phacoemulsification surgery from the patient files. The phacoemulsification was performed using the Alcon Infiniti™ Vision System. UST and EPT values detected during uncomplicated phacoemulsification surgery were recorded. MFT and FV values were measured by OCT preoperatively and on the postoperative 1st day, and at 2nd, 4th, and 14th weeks.
Results: A statistically significant improvement in visual acuity was found in all eyes on the postoperative 1st day, and at the 2nd, 4th, 14th weeks (p<0.005). MFT and FV values were significantly increased on the postoperative 2nd, 4th and 14th weeks compared to the preoperative period (p<0.005). Mean UST and EPT values detected during surgery were 128.71±44.47 sec, and 22.02±8.39 sec respectively. UST and EPT values were not positively correlated with the MFT and FV values.
Conclusion: There was a significant increase in MFT and FV values after uncomplicated phacoemulsification surgery. However, there was no significant relationship between MFT and FV increase and UST and EFT.
