Cataract surgery with toric intraocular lens for correction of high corneal astigmatism.

OBJECTIVE

To analyze the outcomes of cataract surgery with high-power toric intraocular lens (IOL) implantation in patients with high corneal astigmatism.

DESIGN

Retrospective case series.

PARTICIPANTS

Twelve eyes of 9 patients.

METHODS

Patients with idiopathic, pathologic, or postsurgical corneal astigmatism and a visually significant cataract were included in the study. Cataract extraction with implantation of a custom-made high-power toric IOL was performed on all patients. Outcomes included uncorrected and best corrected distance visual acuity (UDVA and BCDVA), manifest refraction, and mean and steepest keratometry. Analysis of astigmatic vectors was also performed.

RESULTS

The mean follow-up time was 3.75 months. At the last follow-up visit, there was a significant improvement of UDVA (1 ± 0.64 vs 0.39 ± 0.21 logMAR; p < 0.05), cylindrical refraction (-4.72 ± 1.13 vs -1.81 ± 1.10 D; p < 0.01), and refractive spherical equivalent (-4.56 ± 5.58 vs -0.36 ± 1.19 D; p < 0.05). The BCDVA improvement did not reach statistical significance. Astigmatism on the target axis was reduced by an average of 5 D (p < 0.01).

CONCLUSIONS

Cataract surgery with implantation of a high-power toric IOL was safe and effective in correcting high values of corneal astigmatism.
