# Blurred Vision After Laser Eye Surgery Source page: https://www.kudretgozistanbul.com/en/blog/eye-diseases/blurred-vision-after-laser-eye-surgery **Author:** Kudret Eye İstanbul | **Medical Approval:** Op. Dr. Mehmet Ali Özdil | **Date:** 2026-09-08 > **Summary:** Blurred vision after laser eye surgery (performed for myopia, hyperopia and astigmatism) is usually a natural, temporary part of recovery. Its duration depends on the cause and the method used, but certain warning signs call for prompt contact with a doctor. ## Quick Facts - **Corneal oedema blurring:** Clears within one to two weeks - **Dry-eye blurring:** Treated within a few days with artificial tears - **Prescription settling:** Mild blurring possible for three to six months - **SMILE:** Most return to daily activities the next day; sharpness may settle a few days later than after LASIK - **No Touch Laser / PRK:** Sharpness takes longer to settle; stabilisation can take months - **Fastest recovery:** LASIK --- ## Why Blurring Happens - Each eye may recover at a different speed, so the slower eye sees more blurred. - Intraocular pressure can rise in some people after surgery. - Dry eye is very common because tear production falls after the operation. - Very rarely, corneal infection; corneal procedures can also cause oedema with swelling and temporary blur. - A prescription difference between the eyes before surgery can make one eye adapt differently or more slowly. - Corneal abrasions and, rarely, regression (the prescription partly returning) can cause blurring and a longer recovery. - In LASIK, the epithelium can grow while the flap is lifted, leading to complaints and blurred vision. - Natural changes in refractive error can cause blurring for a while. ## How Long Does It Last? - **Infection:** clears as the infection is treated and subsides. - **Corneal oedema:** one to two weeks, depending on how long the oedema takes to settle. - **Dry eye:** a few days with artificial tear drops. - **Prescription settling:** three to six months while the treated eye adapts. - **By method:** LASIK recovers fastest; after SMILE most return to daily activities the next day, though sharpness may settle a few days later than after LASIK; after No Touch Laser, PRK and TransPRK sharpness takes longer to settle and stabilisation can take months. ## Helping Blurring Clear Faster - Do not strain the eyes in the first few weeks: avoid long screen time, heavy light exposure and too much reading. - Use artificial tears to keep the eyes moist. - Wear glasses with UV protection against sunlight for the first few weeks; sunglasses outdoors. - Eat meals rich in omega 3 fatty acids and vitamins. ## Is It Dangerous? Usually not: it is expected to clear by itself within a few weeks. If it is very prolonged or considerable, contact an ophthalmologist promptly and be examined for infection risk. Post-operative check-ups show whether there is a problem beyond the natural course and must not be neglected. ## When to Contact a Doctor Immediately Mild stinging, watering, light sensitivity and fluctuating vision are normal in the first days. Contact your doctor without waiting if you have: - Increasing or severe eye pain, especially worsening hour by hour - Vision growing steadily worse, or sudden noticeable blurring - Heavy redness with discharge (may need assessment for infection) - A marked increase in light sensitivity - Noticeable swelling, excessive watering, a feeling the lid is closing, or complaints increasing rapidly despite prescribed drops These signs are rare; early assessment helps bring problems under control quickly. ## Aftercare - The first week needs particular care. - Do not shower for the first 24 hours. - For the first week, keep water, soap and shampoo out of the eyes. - Avoid swimming pools and the sea for about 20 days. - No eye make-up for a few weeks; keep cosmetics, make-up removers, perfumes and chemicals away from the eyes. - Avoid activities that strain the eyes (risk of eye fatigue and dry eye). - Stinging, burning, redness and watering are normal; see a doctor if they worsen. --- ## Frequently Asked Questions **Q: Is blurred vision normal after laser?** A: Yes. Blurring, light sensitivity and fluctuating vision are common in the first hours and even days and lessen as recovery progresses. **Q: How long does the blurring last?** A: It depends on the method: LASIK recovers quickest; after SMILE most return to daily activities the next day, though sharpness may settle a few days later than after LASIK; with No Touch, PRK and TransPRK sharpness can take longer to settle and stabilisation can take months. **Q: Is it bad if one eye is blurrier than the other?** A: The eyes may not recover at the same rate. If the difference is marked or increasing, a check-up is recommended. **Q: Does dry eye cause blurring?** A: Yes, it is a common cause of temporary blurring and stinging. Artificial tears generally help; if it continues, the doctor's plan matters. **Q: When should I see a doctor urgently?** A: With severe pain, increasing redness or discharge, steadily worsening vision or a marked increase in light sensitivity. --- ## References - American Academy of Ophthalmology (LASIK) - Moorfields Eye Hospital (laser eye surgery) - Mayo Clinic (LASIK eye surgery)
