There are many different types of myopia correction surgeries that are suitable for patients with different eye conditions, and it is not possible to simply evaluate which one is best. Patients with low to moderate myopia are better suited for laser surgery, while patients with high myopia are better suited for posterior chamber IOL implantation in crystalline eyes.
Laser surgery for myopia correction can be subdivided into different types such as semi-femtosecond laser surgery and full-femtosecond laser surgery. Semi-femtosecond laser surgery is more suitable for patients with low to moderate myopia who have been examined by corneal topography and have obvious high-order aberrations, while full-femtosecond laser surgery is more suitable for patients with low to moderate myopia who have less obvious high-order aberrations.
Posterior chamber IOL implantation in crystalline lens eyes is suitable for patients with high myopia, especially those with ultra-high myopia of more than 1,000 diopters, and there is less risk of complications such as secondary cone cornea compared with laser surgery.
Myopia patients who want to be treated by surgery need to go to the ophthalmology department of a regular hospital for examination, and the doctor will make a surgical plan after fully evaluating their eye conditions.
