Can surgery correct blurry vision?


Quick Answer

Surgical procedures can correct blurred vision; the appropriate surgical procedure depends on the cause of the blurry vision. Some causes of blurry vision that surgery can address include cataracts, glaucoma, and refractive errors such as nearsightedness, farsightedness, astigmatism and presbyopia.

Cataracts often occur in the elderly. In this condition, the lens of the eye becomes cloudy and opaque. Cataract surgery involves cleaning out, removing or replacing the diseased lens with an intraocular lens implant.

In glaucoma, increased pressure inside the eye results in blind spots, loss of peripheral vision or poor night vision. As there no definitive cure for glaucoma, surgical interventions offer temporary relief. Canaloplasty opens the Schlemm's canal of the eye, thereby relieving pressure. In argon laser trabeculoplasty, the eye surgeon fires a laser spot at the eye's trabecular meshwork to increase the outflow of aqueous fluid.

Refractive errors occur when the lens of the eye fails to properly focus light onto the retina to form an image that can be interpreted by the brain, producing various conditions such as nearsightedness, farsightedness and astigmatism. LASIK surgery can correct these kinds of errors by reshaping the cornea so that the lens can properly focus light onto the retina. Commonly part of normal aging, presbyopia is the loss of the lens's ability to focus on objects that are close by. A corneal implant called the KAMRA inlay blocks unfocused peripheral light rays from entering the eye, while allowing central light rays in to improve near vision.
