Many people choose to wear contact lenses for aesthetic reasons. But contact lenses also have many inconveniences, such as removal and care, and they can have an impact on eye health. Nowadays, many people are starting to undergo myopia surgery to remove their glasses and enjoy seeing the world clearly with their bare eyes. If you are also planning to have myopia surgery, you will need to stop wearing your contact lenses for a rigorous examination before surgery. Why should I stop wearing contact lenses before my myopia surgery? Discontinuing contact lenses is one of the scientific procedures that must be followed for myopia surgery. The purpose of discontinuing contact lenses is to allow the cornea to fully recover its original shape so that the preoperative refractive error will not affect the accuracy of the surgical correction. The purpose of discontinuing contact lenses is to allow the corneal epithelium to return to normal, especially the damaged corneal epithelium. The purpose of discontinuing contact lens wear is to clean the eyes before surgery, as wearing contact lenses may introduce bacteria into the eyes at the same time, compromising surgical safety. There are requirements for contact lens withdrawal time prior to myopia surgery: Depending on the type of contact lens (soft or hard) and the wearing habits (occasional or regular wear) and time, there is a withdrawal period for each type of contact lens, depending on its impact on the cornea (thickness and elasticity). The general time requirement is as follows: soft contact lenses (except toric lenses) should be stopped for one week hard contact lenses and soft contact lenses with astigmatism should be stopped for 3 weeks to more than one month OK lenses (i.e., keratoplasty lenses) should be stopped for more than 3 months. This is all about why you should stop wearing contact lenses before myopia surgery. Before myopia surgery, you need to have a detailed communication with your doctor, stop wearing contact lenses according to your doctor’s suggestion, and undergo a strict pre-operative examination, and choose a suitable surgery method according to your examination results and personal wishes.
