Results of the AcrySof Toric intraocular lenses implantation.
BACKGROUND
The expectations of post-removal cataract surgery patients are extremely high, and best vision acuity is expected. The best refractive results are influenced by two factors - cataract surgical removal and the corneal astigmatism correction. Currently, the two most often applied corneal astigmatism removal methods are laser surgery and toric intraocular lens implantation, with the latter method being both more stable and more reversible. This study aimed to estimate the surgical astigmatism correction efficiency after AcrySof Toric intraocular lens implantation in patients with corneal astigmatism.


METHODS
We used the AcrySof Toric IOL 1-part hydrophobic acrylic lenses. The retrospective research covered 30 eyeballs in 28 cataract and corneal astigmatism patients, with the AcrySof Toric lens implanted by one surgeon.


RESULTS
In our test group 92.31% of post-surgical patients (phacoemulsification and toric lenses implantation) gained the best uncorrected visual acuity, range 0.6-1.0; and in 7.69% of patients the acuity was 0.4-0.6. Lens rotation was examined three weeks after the surgical procedure and a 3.24 ± 3.41 degree axial displacement was observed; however, this lens rotation was clinically unimportant. Based on the analysis of post-surgical results, the corneal astigmatism was 84.2% lower than before the procedure.


CONCLUSIONS
We noticed clinically and statistically important vision acuity improvement in the corneal astigmatism patients. The patients' high satisfaction was conditioned by proper pre-surgery qualification. Astigmatism correction by cataract removal surgery is a safe and effective surgical solution. In the future, we expect the use of toric intraocular lenses will become widespread and significant.
