1, less than 400μm: there is a certain risk in theory. With the fluctuation of intraocular pressure and other unfavorable factors, it may have adverse effects on corneal morphology and other parts of the eye;
2.480-500μm: The corneal thickness is thin, so excimer laser surgery is generally needed, so caution is needed;
3. When it is larger than 550μm: If the patient has moderate or low myopia, excimer corneal surgery is relatively safe. If patients with thin cornea and high myopia want to correct myopia, they can choose ICL, that is, intraocular lens implantation with lens eyes to correct myopia. This kind of surgery has no obvious requirements for corneal thickness, but it has clear requirements for the depth of anterior chamber and posterior chamber. When the depth of anterior chamber is too shallow, it is not suitable for intraocular lens implantation in phakic eyes. Click to test whether I am suitable for myopia surgery.
