摘要
Our case involves a 19-year-old patient with forme fruste keratoconus. Small-incision lenticule extraction was performed, and 6.5 months after surgery, corneal ectasia was diagnosed. Preoperatively, the minimum central corneal thickness was 546 mu m in the right eye and 542 mu m in the left eye; the refractive correction was -6.75 -1.00 x 45 and -6.75 -0.75 x 140, respectively; the lenticular thickness was 137 mu m and 135 mu m, respectively. At 6.5 months, ectasia was diagnosed based on anterior and posterior surface keratometry of 38.4/39.5 diopters (D) and -6.3/-6.8 D, respectively, in the right eye and 38.6/40.8 D and -7.11-6.6 D, respectively, in the left eye. The keratometry increased gradually and the corneal thickness decreased after surgery, and these trends continued during the 13-month follow-up. This report documents corneal ectasia as a complication of small-incision lenticule extraction and highlights the importance of preoperative evaluation and the need for long-term follow-up.
