To understand the refractive outcomes following the use of a readily-available, online toric back-calculator website to assist Toric IOL rotation in selected cases of refractive surprise after cataract surgery
A retrospective, multi-centre review of cases undertaking Toric IOL rotation following initial cataract surgery.
Correcting preoperative refractive astigmatism through the use of toric IOLs is common at cataract surgery. Residual astigmatism can impact uncorrected visual acuity and lead to reduced patient satisfaction. Several options may be available for surgeons including, but not limited to secondary IOL implantation, IOL exchange and IOL rotation. In this case series, calculations were performed using the Berdahl-Hardten (www.AstigmatismFix.com) online calculator for cases of refractive surprise after cataract surgery. Toric IOLs were rotated as per the calculations and then visual and refractive results were analysed.
26 cases were included in this series. Average astigmatism among the participants was 1.00 ± 0.78 D which after IOL repositioning reduced significantly to ≤0.25 D. Visual acuity in these patients improved in average by 2 steps on logMAR score.
Toric IOL rotation can be effective in reducing residual refractive astigmatism in selected cases following cataract surgery. This presentation aims to highlight the refractive and efficacy benefits of undertaking Toric IOL rotation using calculations available from a free, online Toric back-calculator website.
