Toric IOLs improve visual outcomes in eyes treated with MIGS/cataract surgery
Implanting toric intraocular lens (IOLs) during combined cataract and minimally invasive glaucoma surgery (MIGS) in glaucomatous eyes with corneal astigmatism leads to better visual outcomes, according to a study.
In this retrospective study, 18 eyes with open angle glaucoma with preexisting corneal astigmatism of -1.5 diopter (D) or more were included. Toric IOLs and non-toric IOLs were implanted in 9 eyes each, respectively.
The logarithm of the minimum angle of resolution (logMAR) uncorrected visual acuity (UCVA) and refractive astigmatism were similar in each group before surgery.
In the toric IOL group, the logMAR UCVA was significantly better and the refractive astigmatism significantly less after surgery.
Compared to the non-toric group, centroid magnitude and confidence eclipses of refractive astigmatism in the toric group was less postoperatively. Postoperatively, 78% and 11% of eyes in the toric group and the non-toric group, respectively, had ≤1.0 D refractive astigmatism.
