Why should we stop using contact lenses before excimer laser myopia surgery?
First, wearing contact lenses will cause irregular changes in the cornea, and accurate data of preoperative examination cannot be obtained, which will directly affect the postoperative results.
Second, wearing contact lenses will cause the cornea to be in a relatively hypoxic state, and immediate surgery will increase the risk of postoperative infection.
Third, there are many bacteria attached to the mirror surface of contact lenses. Although it is often cleaned, there is a risk of bacterial infection during surgery. Therefore, if you wear soft contact lenses, you can stop using them for at least one week before doing preoperative examination, and you can have surgery for more than one week; If you wear hard contact lenses, stop wearing them for at least 3 months before you can check and operate them.

Before myopia surgery, ordinary soft contact lenses need to be stopped for at least 1 week, hard RGP contact lenses need to be stopped for at least 1 month, orthokeratology lenses are also OK lenses, and orthokeratology lenses need to be stopped for at least 3 months at night. If irregular corneal shape or poor tear quality is found during preoperative examination, it may be caused by wearing contact lenses, and it needs to be stopped for a longer time. It is necessary to improve the corneal topography examination again, and wait until the corneal morphology returns to normal, so as to evaluate whether it is suitable for myopia surgery and arrange the operation method through the normal corneal morphology.
