Purpose:
Corneal topograph-guided laser subepithelial keratomileusis (LASEK) can effectively correct decentered ablation occurring post laser in situ keratomileusis (LASIK) and to enhance our understanding and diagnosis of decentered ablation following LASIK.
Methods:
Previous studies in the relevant literature are reviewed, and a case report is provided.
Results:
A patient with high myopia undergoing LASIK in both eyes presented with distorted vision in the left eye, which interfered with the vision in the right eye and caused blurred vision in both eyes. The patient was unable to see objects with both eyes. After receiving corneal topography-guided LASEK, the signs of distorted vision in the left eye and bilateral blurred vision were significantly alleviated, and the patient could see objects with both eyes simultaneously.
Conclusion:
Clinical ophthalmologists should be aware of the occurrence of decentered ablation after LASIK. Corneal topography-guided LASEK is an efficacious tool for correcting decentered ablation.
