Myopia surgery is relatively safe, but it is essential to understand the specific indications and contraindications before undergoing such a procedure. Firstly, myopia surgery involves operations on the cornea, including the creation of a concave lens on the surface, and intraocular procedures, such as the implantation of artificial lenses for those with lens-related issues. If there are other underlying retinal problems, these conditions are absolute contraindications. For surgeries on the cornea, it is crucial to measure the corneal thickness and rule out conditions like keratoconus. Once the contraindications and indications are properly assessed, these surgeries are very safe to perform.
