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.


METHODS
Retrospective case series.


METHODS
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.
