Side effect of lasik surgery3/10/2023 Glare, halos and double visionĪfter your LASIK surgery, you may have challenges with night vision that usually last a few days to a few weeks. What are some side effects of LASIK?Īlthough complications that result in vision loss are relatively uncommon, certain side effects of LASIK eye surgery, such as dry eyes and temporary glares, are fairly prevalent. AstigmatismĪstigmatism occurs when the cornea or lens (responsible for the focusing mechanism of the eye) curves or flattens unevenly, light reaches various points on the retina and disrupts the focus of vision nearby and at a distance. As a result, your near vision becomes blurry. Thus light focuses behind the retina instead of on it. Hypermetropia (farsightedness) occurs when you have a shorter than average eyeball or a cornea that is too flat. Consequently, you can see objects at near fairly clearly, but objects at a distance are blurry. Hence light rays focus in front of the retina and blur distant vision. Myopia (nearsightedness) occurs when your eyeball is slightly longer than normal or when the cornea curvature is steep. LASIK surgery may be done for the vision correction of: Myopia While glasses or contact lenses can correct vision, reshaping the cornea itself via LASIK eye surgery can also correct a refractive error, providing clear vision. If you have any refractive error such as myopia (nearsightedness), hypermetropia (farsightedness), astigmatism or presbyopia, the light is bent incorrectly behind or in front of the retina, leading to blurred vision. If you do not have a refractive error, when light enters the eye, the cornea bends or refracts light precisely onto the retina (the light-sensitive tissue at the back of the eye). This article will briefly outline some of the side effects of LASIK surgery. During a LASIK surgery, the surgeon would use a special type of laser to precisely adjust the curvature of the cornea of your eye (the shape of the dome-shaped clear tissue at the front of your eye) to enhance vision. LASIK (laser-assisted in situ keratomileusis) eye surgery is the most widely known and most common laser refractive surgery for vision correction.
