Abstract

Outcomes of toric IOL surgery depend on correct intraoperative alignment and postoperative rotational stability. Patients with gross misalignment and sub-optimal visual outcomes require realignment surgery. Post-operative toric IOL position can be evaluated using various tools. We assessed the position of toric IOL in 52 patients undergoing re-alignment surgery based on wavefront aberrometer, using slit lamp and wavefront aberrometer method. Median logMAR UCVA significantly improved from 0.48 pre-realignment to logMAR 0.00 post re-alignment. Median refractive cylinder decreased from -1.50D to 0.00D post re-alignment surgery. There was no difference in mean axis estimated using wavefront method and slitlamp method (47.7±20.1˚ vs 46.6±20.5˚ preoperatively and 5.5±5.9˚ vs 5.7±6.0˚ post-operatively). Bland –Altman analysis revealed high degree of agreement between the methods for assessing toric IOL axis. Hence, slit lamp method can be effectively utilized in resource constrained setting.
