Blurred vision that requires laser refractive surgery is often due to refractive errors that cannot be adequately corrected with glasses or contact lenses. Here are the primary conditions that might lead someone to consider laser surgery:
Blurred Vision
Astigmatism
Astigmatism is a common refractive error of the eye caused by an irregular shape of the cornea or lens. Instead of being perfectly spherical, the cornea or lens has a more oval shape, which can cause blurred or distorted vision at all distances.
Myopia (Short-sighted)
Myopia, commonly known as nearsightedness, is a refractive error of the eye where distant objects appear blurry while close objects can be seen clearly. This occurs when the eyeball is too long or the cornea has too much curvature, causing light rays to focus in front of the retina instead of directly on it.
Hypermetropia (Long-Sighted)
Hypermetropia, also known as farsightedness, is a common refractive error of the eye where distant objects can be seen more clearly than nearby objects. This occurs when the eyeball is too short, the cornea has too little curvature, or the lens is less flexible, causing light rays to focus behind the retina rather than directly on it.
