Case 1 - A 33-year-old male patient presented at the refractive surgery clinic with complaints of decreased visual acuity in the right eye. Bilateral FS LASIK had been performed 12 years earlier. His uncorrected visual acuity (UCVA) was 20/200 in the right eye and 20/20 in the left eye. Manifest refraction values were -1.25 x65 in the right eye and -0.25 in the left eye. The BCVA in his right eye was 20/63. Corneal topography (Pentacam; Oculus Optikgerate GmbH, Wetzlar, Germany) findings were compatible with corneal ectasia in the right eye and a postmyopic ablation pattern in the left eye (Fig. 1). A Corvis ST and Pentacam biomechanical/tomographic assessment was performed. All of the topographic and biomechanical index values are listed in Table 1. Although the topographical and clinical findings were not consistent with corneal ectasia in left eye, the CBI, TBI, and BAD-D values suggested biomechanical weakness (Fig. 2). Corneal crosslinking (CXL) was planned for the right eye. It was not pursued immediately for left eye since the UCVA had not deteriorated. The patient was informed about the possibility of ectasia development in the left eye, follow-up was recommended, and he was advised not to rub his eyes.
