Abstract Details


To report the results, the surgical technique and complications of patients treated with topography guided PRK and simultaneous corneal cross linking for the treatment of keratoconus.


Private office-Athens Refractive Center, Athens, Greece


10 eyes of 10 patients with keratoconus were treated with topography guided PRK followed by same day cross-linking. Excimer laser ablation was performed with the Swind Amaris 750Hz and corneal cross-linking was performed with the Avedro CXL machine. Excimer laser ablation was limited up to 50microns of the anterior stroma and aimed to improve the patient’s corneal aberrations and not to treat the patient’s total refractive error.


Uncorrected visual acuity and best spectacle corrected visual acuity improved in all patients included in the study. One patient developed mild haze of the anterior stroma which was succefully treated with prolonged therapy of steroid drops.


Topography guided PRK combined with CXL is a good option for patients suffering from keratoconus. FINANCIAL DISCLOUSRE: NONE
