Purpose
The study aims to assess the results of toric posterior chamber phakic intraocular lenses (IOLs) implantation to correct high myopia with myopic astigmatism.
Setting
Oftalmika Eye Hospital, Bydgoszcz, Poland
Methods
This retrospective, consecutive, observational case series comprised 66 eyes with myopic astigmatism which underwent posterior chamber toric phakic IOL implantation (EVO Visian ICL, Staar Surgical). Preoperative mean refractive astigmatism was -1.90 ± 1.28 Dcyl, and spherical equivalent was -11.13 ± 3.66 D. Refractive results, surgically induced astigmatism (SIA), predictability, safety, and efficacy were evaluated 2 to 4 months postoperatively.
Results
After the surgery, mean refractive astigmatism was -0.28 ± 0.43 Dcyl and spherical equivalent -0.13 ± 0.54 D. Postoperatively, 75.76% of the eyes were within ±0,5 Dcyl of refractive astigmatism, and 90.91% within ±0,5 D for spherical equivalent. The double-angle plot showed the centroid value for refractive astigmatism of 0.13 D @107 ±0.49 D. The average centroid of SIA on the right cornea was 0.06 D @122 ±0.28D and 0.15 D @74 ±0.33D for the left. None of the patients experienced visual acuity line loss; 56.06% gained 1 to 3 lines. The average BCVA increased from 0.83 ± 0.30 to 0.98 ± 0.21. A significant increase in IOP was not observed after the implantation.
Conclusions
The implantation of a toric posterior chamber phakic IOLs provides good results in efficacy, safety, predictability, and visual outcomes in eyes with high myopia with myopic astigmatism.
