Purpose

To compare endothelial cell (EC) loss, visual and refractive outcomes, after Femtosecond laser-assisted and manual PK for corneal stromal pathology.

Setting

Ophthalmology department Dnipro State Medical University, Dnipro regional Ophthalmology Hospital.

Methods

 Retrospective comparative case series: group 1 is 76 eyes treated with  Femtosecond laser-assisted PK and group 2 is 52 eyes treated with manual PK between 2014 and 2023. Corneal endothelial cell density (ECD) using specular microscopy, visual acuity and astigmatism was examined at postoperative 1, 5 and 10 years.  

Results

Corneal ECD reduction in the first group was 72% and 75.9% in the second group at 10 years respectively after surgery (the difference is not statistically significant). 27 of the 128 participants (21.1%) had an ECD of <500 cells/mm2 at 10 years. The mean astigmatism after suture removal was 3.76 ± 2.1 D with no significant differences in both groups

Conclusions

Ten years after PK performed for stromal corneal diseases involving endothelium, EC loss ranged from 72 to 75.9%.The surgical technique did not affect EC loss.
