Abstract

Purpose: To evaluate role of real-time intraoperative imaging during FLACS

Methods: Prospective analysis of 97 eyes undergoing FLACS. Intraoperative imaging was performed using LenSx inbuilt OCT and microscope integrated iOCT

Results: Senile cataract was present in 51/97 eyes, 21/97 white cataract, 18/97 posterior polar (PPC) and 7/97 eyes had subluxation.

During laser planning, OCT helped delineate PC status in 77.8% PPC cases; predict fluid release in 100% of white cataract and visualize magnitude of lens tilt, customize centration and size of capsulotomy in cases with subluxation.

During phacoemulsification, PC status was continually assessed during phacoemulsification using miOCT to enhance safety in PPC. Residual capsulotomy tags were visualized in 47.6% white cataract cases. IOL stability and centration was assessed in subluxated cases.

Conclusion: In vivo assessment of intraoperative dynamics with OCT enhances safety of FLACS in different morphological variants of cataract.
