Objectives To evaluate the results of toric intraocular lens (IOL) implantation during cataract surgery in eyes with high regular astigmatism associated with prior penetrating keratoplasty (PK). Methods A retrospective data analysis of patients with prior PK, who underwent uncomplicated cataract surgery with hydrophobic toric single piece IOL (EyeCryl Toric (R), Biotech Vision Care, Luzern, Switzerland). Results A total of 18 eyes of 18 patients were included in the study. The mean age was 53.4 +/- 12.4 (25-70) years. The mean follow-up period was 15.5 (4-24) months. The mean best corrected visual acuity (BCVA) significantly increased from 1.36 +/- 1.0 logMAR to 0.31 +/- 0.17 logMAR (p < .001) pre- and post-operative 4 weeks, respectively. There was no significant change in mean BCVA during follow-up; mean BCVA was 0.32 +/- 0.17 logMAR at the last visit. The mean pre-operative topographic astigmatism was 6.52 +/- 1.80 diopters (D). The mean manifest refraction astigmatism was decreased from 6.55 +/- 1.62 D to 2.80 +/- 1.43 D (p<0.001). The mean Surgically induced astigmatism (SIA) was 3.74 +/- 0.77 D according to vector analysis. There was no patient with graft rejection or failure, the mean endothelial cell loss rate was 12.75 +/- 3.76% (7-17%). There was no patient requiring IOL reposition. Conclusions Toric IOL implantation during cataract surgery provides an option to correct astigmatism in post-PK eyes with high regular astigmatism. When appropriate patients are selected it is a safe method to achieve significant improvements in visual acuity and astigmatism.
