People with thin corneas can also have myopia correction surgery. After examination, if the cornea thickness is thin, but the retained corneal thickness can still be greater than 430 micrometers after laser corrective surgery, it is possible to consider laser surgery to correct myopia. If the cornea thickness is thin and the cornea thickness retained after the myopia correction surgery is calculated to be too low to achieve a safe corneal thickness, then the patient is not suitable for laser myopia correction surgery. However, for people with particularly thin corneas, they can be treated with posterior chamber IOL implantation in crystalline eyes. IOL implantation in crystalline eyes will not further reduce the thickness of the cornea, so it is safe for patients with thin corneas. Myopia surgery requires a detailed examination at a regular hospital before deciding whether it is suitable.
