Can those who have undergone laser surgery wear contact lenses

After undergoing laser surgery, it is generally possible to wear contact lenses, but they must be worn after the surgery has stabilized and confirmed by a doctor's assessment. Early after corneal laser surgery, there may be issues such as dry eye and corneal sensitivity, and it is necessary to avoid wearing contact lenses immediately.

Corneal laser surgery changes refractive power by cutting the cornea, and postoperative corneal morphology and nerves require time for repair. Usually, 3-6 months after surgery, after the corneal healing is stable and tear secretion returns to normal, after confirmation by an ophthalmologist that the cornea is not edematous, the epithelium is intact, and there are no persistent dry eye symptoms, it may be considered to wear low water content, high oxygen permeability daily throwing contact lenses for a short period of time. When wearing, it is necessary to strictly follow the 4-6 hour time limit to avoid prolonged coverage of the cornea that affects oxygen exchange. At the same time, artificial tears should be used to relieve dry eyes. If there is delayed corneal healing, persistent dry eye, or unreleased corneal nerve sensitivity after surgery, wearing contact lenses may increase the risk of corneal hypoxia, mechanical friction damage, or infection. Especially for those who have incomplete corneal flap healing after full femtosecond surgery, contact lens adhesion may cause corneal displacement. In addition, direct contact of the colored layer of contact lenses with the cornea may cause allergic reactions and increase the probability of keratitis.

It is recommended to choose silicone hydrogel materials with oxygen permeability coefficient exceeding 100DK/t under the guidance of doctors to avoid using inferior products. Strict cleaning and care are required before and after wearing. If there is redness, foreign body sensation, or blurred vision, it should be immediately stopped and re examined. During the postoperative recovery period, frame glasses should be given priority to reduce corneal burden, and corneal topography should be regularly reviewed to assess stability.
