LASIK can correct vision problems like astigmatism, but not everyone is an ideal candidate. Learn more about LASIK for astigmatism and whether it’s right for you.

If you’re experiencing headaches, blurred vision, eye strain or trouble seeing at night, you may have a common eye condition called astigmatism. Research indicates that astigmatism accounts for roughly 13% of refractive errors (vision problems that make it difficult to see clearly)[1] . The issue, however, is very common in America with approximately one-third of Americans having astigmatism[2]. Astigmatism is caused by an imperfection in the shape of your cornea (the surface layer of your eye ) or lens (an interior part of the eye that helps ...
Waking up with the ability to see straight across the room is a luxury that isn’t granted to everyone. If you dream of clear vision without glasses or contacts, there’s a good chance laser eye surgery is right for you. LASIK may be the first thing that comes to mind when you envision eye procedures. Short for laser-assisted in situ keratomileusis, it’s the most commonly performed corrective eye surgery, but it isn’t the only option to choose from[1] . Photorefractive keratectomy (PRK) is another widely used tool that’s been around for ...

What is LASIK? ; LASIK is a laser eye surgery used to treat myopia, nearsightedness, farsightedness and astigmatism. By protecting the corneal epithelial cells, there is extremely little pain or discomfort after surgery. This procedure called Keratomileusis was first devised by the Spanish ophthalmologist Dr. Jose Barraquer in Colombia in 1949, and has been used to operate on severe myopia. This procedure was further developed over the years with advancements in keratotomy. In 1980, laser keratectomy was performed using an excimer laser, which ...
