Abstract:
Objectives:To evaluate and compare ectasia and pseudoectasia in post-myopic LASIK patients presenting with
corneal topographic changes indicative of ectasia using the Ectasia Risk Factor Score System (ERFSS).
Methods:Single-center retrospective comparative case series of a consecutive chart review of cases in 18 years
who underwent bilateral myopic-LASIK and showed topographic changes indicative of ectasia.
Results:Four patients were included. Group 1: pseudoectasia eyes, consisting of two patients with bilateral
pseudoectasia, and Group 2: ectasia eyes, consisting of two patients with unilateral ectasia. The clinical course of the cases was discussed and compared based on the ERFSS parameters: topography pattern, residual stromal bed thickness, age, preop thinnest cornea, and pre-operative spherical equivalent (SE) manifest refraction (MR). Group 1 scored zero to low risk for developing ectasia while Group 2-eyes with ectasia scored moderate risk. The predictive value of the ERFSS was 1 in this study.
Conclusion:The ERFSS is a good measure in deciding the suited treatment plan for patient undergoing refractive procedure. Knowing the clinical course of ectasia and pseudoectasia is helpful in the therapeutic approach since pseudoectasia is reversible when identified and managed early as seen in this study.
