In a large retrospective, single-site study, there were similar outcomes in patients who received repositioning surgery after toric IOL implantation.

In what may be the largest series to date to report on the outcomes of toric IOL repositioning surgery, 2.4% of patients receiving a hydrophobic lens and 1.6% with a hydrophilic acrylic lens required repositioning surgery, said Aravind Haripriya, MBBS, Aravind Eye Hospital, Chennai, India.
Visual outcomes were good for both groups after surgery. The study was a retrospective case series of 4,273 patients who had toric IOL repositioning between 2015 and 2017 at Aravind Eye Hospital.
Patients received a hydrophobic acrylic toric IOL (SN6AT, AcrySof; 733 patients) or hydrophilic acrylic (FH560; 3,540 patients) toric IOL. The average patient age was 61.8 years, and there was a mean preoperative astigmatism of 2.33 D. The mean axial length was 23.19 mm, and the mean IOL power was 18.75 D.
The IOL alignment was assessed after surgery via the slit lamp, with maximum pupillary dilation. If the toric IOL axis on the slit lamp was misaligned more than 5° from the intended axis, the IOL position was reconfirmed using ray-tracing technology (iTrace, Tracey Technologies). On day 15 postoperatively, patients were seen again to be reassessed for their IOL position and to plan for repositioning surgery if needed.
