Advanced Tope-guided/Oculink PRK and CXL Beneficial for the Visual Outcome in Patients with Keratoconus, Corneal Ecstasia and Thin Corneas

Klajda Bardhi, Jonid Bilbili, Minir Asani

Aim: To stop the keratoconus or the progression of the corneal thinning, to reduce the irregular astigmatism and improve BCVA. 6 year study and follow up of the first patients usually every 2-3 patients every month, almost 120 patients in 6 year.

Methods: PRK using Wave light eximer EX 500 nm and CXL UV 300 nm. To these procedures, we added a combined treatment referring to Oculink or topography guided to ameliorate the cornea irregularities-also using Vibex Rapid which is with a twice diffusion rate than the standard riboflavin.

Election of the candidates: Not all the patients with keratoconus can succeed to topography guided PRK+CXL +oculink/topography guided+Vibex rapid – the most probable are Kc1, Kc1-Kc2, kc2 with k1-K2 not too high.

Conclusion: Topography guided PRK+CXL is the most adequate method of stopping and improving the vision in patient with keratoconus, and in irregular astigmatism, or thin corneas topography guided is a safer method for not having complications in time, the goal of treatment is to flatten the steepest part of the cornea and to steepen the flattest area of the cornea.
