Abstract

PURPOSE
We report a case of transient corneal opacity and hyperopia after LASEK surgery.
CASE SUMMARY
A 21-year-old female visited our clinic complaining of decreased visual acuity in the left eye. The patient had undergone LASEK surgeryten days previously. Before LASEK surgery, the central corneal thickness of the left eye was 540 micrometer, and the refractive error was -2.00 Dsph=-0.75 Dcyl x80A with an estimated ablation depth of 52.2 micrometer. At the time of visit (on the tenth day after surgery), the best corrected visual acuity (BCVA) was 0.07, the central corneal thickness was 404 micrometer, and the refractive error was +1.00D=+1.25D x90. Slit-lamp biomicroscopy showed round central corneal haziness, but there were no signs of inflammation. At the third weeks after surgery, the central corneal thickness was 401 micrometer and the refractive error was +11.25D=-4.00D x145. Slit-lamp biomicroscopy showed sustained round central corneal haze. Twenty-two weeks after surgery, the central corneal thickness was 445 micrometer and the refractive error was -0.75D=-1.25D x180. The corneal opacity had disappeared.
CONCLUSIONS
In case of transient corneal opacity, stromal loss and hyperopic change after LASEK surgery, central toxic keratopathy should be considered.

  • Figure 1. Anterior segment photograph and corneal thickness map of Pentacam in left eye of a 21 years old female who underwent LASEK 10 days ago. (A) Anterior segment photograph showed central subepithelial circular corneal haziness. (B) The thickness of central cornea was noted 404 μm in Pentacam map.

  • Figure 2. Postoperative 3 weeks, left eye. (A) Central subepithelial circular corneal haziness was persisted. (B) The thickness of central cornea was noted 401 μm in Pentacam map.

  • Figure 3. Postoperative 22 weeks, left eye. (A) Corneal haze was almost disappeared. (B) The thickness of central cornea was noted 445 μm in Pentacam map.
