8.5/8.6-mm Excimer Laser–Assisted Penetrating Keratoplasties in a Tertiary Corneal Subspecialty Referral Center: Indications and Outcomes in 107 Eyes
Purpose:
To report the indications and outcomes of 8.5/8.6-mm excimer laser–assisted penetrating keratoplasties (PKPs) at a tertiary corneal subspecialty referral center.
Methods:
This retrospective, descriptive, observational study included 107 PKPs performed in 96 patients (mean age, 53 ± 12 years). The patients' indications for surgery, best-corrected visual acuity, surface regularity index, surface asymmetry index, topographic astigmatism, central endothelial cell density, central corneal thickness, and graft status were recorded preoperatively, 6 weeks postoperatively, and before (12 ± 2 months) and after (19 ± 4 months) the suture removal.
Results:
The surgeries included 48 primary PKPs and 59 repeat PKPs. The main indications were corneal ectatic disorders (50%), severe corneal keratitis (21%), and corneal scars (16%) in the primary PKP group and highly irregular astigmatism after PKP (51%) and previous graft decompensation (37%) in the repeat PKP group. From preoperative measurements to the last follow-up visit without sutures, we found significant improvements (P
