Post-keratorefractive Ectasia
摘要
Corneal keratoectasia is a significant complication that can occur after laser keratorefractive procedures such as LASIK, PRK, and SMILE. This condition leads to visual impairments, including glare, halos, double images, ghosting, and reduced visual acuity, often due to increased myopia and/or irregular astigmatism. Management strategies focus on preventing visual deterioration, alleviating symptoms, and preserving or restoring visual function. Treatment options range from rigid gas permeable or scleral contact lenses to intracorneal ring segments (ICRS) and corneal cross-linking (CXL), with severe cases requiring corneal transplantation. These approaches emphasize the importance of accurate diagnosis and effective management of post-refractive ectasia, with CXL playing a central role in treatment.
