There are several types of surgery to correct myopia: 1. Excimer laser myopia correction surgery, which is the use of excimer laser for myopia correction, and generally does not require hospitalization and can be done in an outpatient setting. 2. Femtosecond laser myopia correction surgery, which is the use of femtosecond laser to correct myopia, which is also an outpatient procedure and does not require hospitalization. 3. IOL implantation surgery for crystalline eyes, also known as ICL surgery, is more suitable for patients with high myopia. This surgery requires inpatient treatment, usually for about three days. 4. Clear lens extraction surgery, for patients with high myopia who cannot undergo laser treatment or IOL implantation, requires clear lens extraction to correct myopia. This surgery requires hospitalization, usually for about three days. In summary, hospitalization should be determined depending on the type of corrective surgery.
