To evaluate the results of toric intraocular lens
(IOL) implantation in patients with cataract
and postpenetrating keratoplasty astigmatism
Seven eyes of 7 patients with cataract
and more than 3.5 diopters (D) astigmatism
following penetrating keratoplasty
were included in this retrospective case series study. All of the eyes underwent phacoemulsification and Acrysof toric IOL (t5–t9) implantation at least 6 months later than the complete suture removal. Corrected visual acuity (CVA), manifest astigmatism
, the keratometry measurements, and complications were assessed.
The mean preoperative CVA significantly increased (0.7±0.3 [range: 0.3–1.3] logMAR to 0.1±0.04 [range: 0.05–0.15] logMAR; P
<0.05) at mean 8.71±4.11 months after the surgery. The mean preoperative corneal astigmatism
and the average manifest refractive astigmatism
at the last visit were 5.4±0.9 D (range: 4.25–7 D) and 1.6±0.6 D (range: 0.5–2.5 D), respectively. The mean attempted cylinder correction at spectacle plane was 4.3±0.9 D (range: 2.4–4.7 D) whereas the mean cylinder correction was 4.6±0.5 D (range: 3.9–5.9 D), showing a slightly tendency for overcorrection. All eyes (100%) were within 1 D of predicted residual astigmatism
. No complication occurred during the follow-up.
Toric IOL implantation seems to be an effective, predictable, and safe procedure in patients with cataract
formation and high astigmatism
after penetrating keratoplasty
