Clinical Outcomes Of Toric Intraocular Lenses In Patients With Fuchs Endothelial Corneal Dystrophy

To evaluate the results of toric intraocular lenses (IOLs) implantation in patients with Fuchs Endothelial Corneal Dystrophy (FECD).

Ein-Tal Eye Center, Tel Aviv, Israel.

A Retrospective, case-control study of 28 eyes of FECD patients and 84 eyes of healthy control patients who received toric IOLs during routine cataract surgery. The outcome measures were: uncorrected and corrected distance visual acuity, spherical equivalent, and refractive residual astigmatism.

The mean postoperative uncorrected and corrected distance visual acuity as well as the spherical equivalent were similar between the FECD and the control eyes. (P=0.32; P=0.95; P=0.19, respectively.) The preoperative corneal centroid astigmatism and the preoperative corneal astigmatism magnitude in the FECD eyes compared to the control eyes were also similar (P=0.43; P=0.82, respectively).  A trend toward higher postoperative refractive centroid astigmatism was found in the FECD eyes compared with the control eyes: 0.24@28º±0.57 vs. 0.03@127º±0.53, respectively, (P=0.09). However, the mean postoperative refractive astigmatism magnitude was similar in FECD eyes and the healthy control eyes: 0.52±0.31D vs 0.42±0.31, respectively, (P=0.44).

The postoperative refractive astigmatism (both centroid astigmatism and mean magnitude astigmatism) was no higher than 0.52D in both groups. Therefore, FECD patients without corneal edema can be considered for toric IOLs.
