Objective: To evaluate early keratometric and refractive results after intra-corneal rings surgery in keratoconus patients.
Method: 50 eyes of 25 patients with keratoconus within stage 2 and 3, underwent intra-stromal corneal rings surgery by using the femtosecond surgical laser, one month after surgery, corneal keratometries and patient refraction were compared vs pre-operative ones.
Results: Mean pre-operative low keratometry was 48.
