Abstract
Purpose:
To evaluate the visual results of performing cataract surgery on patients with astigmatism who received Toric Intraocular Lenses.
Methods:
The outcomes of Toric IOLs performed in one practice by 7 separate cataract surgeons over a 1 year time period were evaluated. A total of 111 patients were evaluated. Standard phacoemulsification was performed for 103 patients, while eight patients underwent surgery with a femtosecond laser. Outcome measures included measurement of UCVA, BCVA and residual astigmatism.
Results:
141 eyes were assessed (58 male, 83 female). The average age was 70 (range 42 to 87). 17.86% of eyes achieved 20/20 or better UCVA. 67.86% achieved 20/30 or better UCVA. 15.71% of eyes ended up with 20/40 or worse UCVA. In this cohort - 83.46% had 20/25 or better BCVA. 6.30% had 20/40 or worse BCVA postoperatively, and this was related to irregular astigmatism that was present on preoperative topography.
Conclusions:
Toric Intraocular Lenses are effective for patients undergoing cataract surgery with pre-existing astigmatism. However, eyes with irregular corneal astigmatism may end up with reduced BCVA, so identification of these eyes preoperatively is important.
