Will laser surgery cause dry eye syndrome?
This is mainly because during the laser surgery, continuous operations on the surface of the eyeball may cause certain damage to the ocular surface. This is mainly related to injuries, ocular surface inflammation, decreased tear film stability, and other factors. Here are the details:
1. Injury: During laser surgery, improper operation may cause damage to the corneal epithelium, resulting in excessively thin corneal epithelium. When the eyeball comes into contact with microorganisms or chemicals in the air, reactive secretions may be produced, leading to symptoms such as dryness, foreign body sensation, etc. It is recommended to go to the hospital promptly and follow the doctor's instructions to use sodium hyaluronate eye drops or other medications for relief;
2. Ocular surface inflammation: After laser surgery, the wound on the eye is relatively small, but it still takes some time to recover. If you do not pay attention to eye hygiene and improper care, it may lead to inflammation on the ocular surface, resulting in symptoms such as redness, swelling, pain, and dryness. It is recommended to go to the hospital promptly and use drugs such as pranoprofen eye drops or tobramycin dexamethasone eye drops under the guidance of a doctor;
3. Decreased tear film stability: As everyone's tear film stability is different, after laser surgery, the stability of the tear film may decrease. If stimulated by external factors, it may cause symptoms such as dryness, photophobia, and tearing. It is recommended to use drugs such as sodium hyaluronate eye drops or hydroxypropyl methylcellulose eye drops under the guidance of a doctor;
4. Others: In addition, some people may experience retinal detachment, refractive error, retinal vein occlusion, and other conditions after laser surgery. It is recommended to follow the doctor's instructions to use eye drops or ointments for local anti-infection treatment after laser surgery. You can also gaze into the distance appropriately to avoid excessive eye use. At the same time, you can also supplement foods rich in vitamin A and lutein, such as carrots.
