Background: keratoconus (KC) is an ectatic condition of the cornea which is usually progressive and noninflammatory, affecting both eyes asymmetrically. It is characterized by stromal thinning that leads to corneal surface irregularity. Vision affection is due to irregular astigmatism and corneal scarring. Aim of the Work: assessment of the effectiveness of Myoring intreating patients with keratoconus. Patients and Methods: prospective non-randomized non-comparative clinically controlled study, Myoring was implanted for (20) eyes of 20 patients with progressive keratoconus. Results: visual acuity and corneal parameters improved significantly in all patients after one year postoperatively. Conclusion: Myoring when used in suitable patients has the potential to produce excellent long-term vision results in mild, moderate and advanced keratoconus cases, regardless of cone position and disease progression.
