To maintain the normal function and structure of the cornea, the corneal tissue needs to have a certain thickness, which is normally 550 μm to ensure that the eye tissue can resist intraocular pressure, and when the cornea becomes thin the resistance to external stimuli will decrease. Patients with thin corneas are clinically advised to try not to do too strenuous sports, and especially to avoid eye trauma, such as boxing injuries or other hard impact injuries that may lead to corneal rupture or even eye rupture. In addition, people with corneas too thin to undergo myopic laser surgery, because myopic laser surgery requires a certain degree of cutting of corneal tissue, and if the corneal thickness cannot be maintained within the normal range, the cutting will lead to further thinning of corneal tissue and cause other secondary diseases.
