Text
Ectasia is one of the most severe side effects after corneal refractive surgery. Risk factors for development of ectasia include high myopia, young patient age, reduced preoperative corneal thickness, reduced residual stromal bed thickness after laser ablation and asymmetrical corneal steepening (forme fruste keratoconus, keratoconus or pellucid marginal degeneration) [1].
Recent approaches to offer corneal refractive surgery to patients with thin corneas, include combining the procedure with corneal cross-linking [2].
Alternatively, intraocular refractive procedures, such as ICL or iris-claw IOLs may be considered.
