To evaluate the efficacy and safety of transepithelial customized photorefractive keratectomy (TE–PRK) using an ultrafast excimers laser to treat irregular astigmatism in complicated cases.
Five eyes of 5 patients after post–LASIK botton–hole (3) and after penetrating keratoplasty (2) were submitted to a customized TE–PRK using a 650µm flying–spot 1000 Hz excimer laser (iRES, Ligi, Taranto, Italia) linked to a computerized tomography unit (Orbscan, Bausch & Lomb, Rochester, USA) using the CIPTA software program (Corneal Interactive Programmed Topographic Ablation).
After a follow up of six months all patients presented an improvement of both refractive and keratometric astigmatism and better UCVA and BSCVA. Nosignificative intraoperative or postoperative complications were noted during the follow–up.
The customized TE–PRK using ultrafast excimers laser brought a satisfactory and stable visual outcome with good safety and efficacy in the treatment of irregular astigmatism in complicated cases.
