What Does LASIK Treat?
LASIK is a popular and advanced treatment for improving vision. LASIK is used to treat refractive errors of the eye. In most cases, these errors happen because the shape of the eye isn’t quite right and, as a result, light doesn’t focus on the retina the way it should. In some cases, refractive errors are corrected with eyeglasses or contacts, but LASIK provides a long-term solution that often results in clearer vision. Common refractive errors include:
- Hyperopia: Hyperopia is commonly referred to as farsightedness. People with this condition may have trouble clearly focusing on nearby objects while they can see things that are far away quite clearly. In this case, light focuses behind the retina instead of on the retina.
- Myopia: Myopia is also known as nearsightedness. In this case, people can usually see nearby objects clearly, but far away objects are blurry or hard to focus on. In this situation, light is being focused in front of the retina.
- Astigmatism: If someone has an astigmatism, the shape of the cornea prevents light from focusing evenly on the retina. Objects at various distances may appear blurry or distorted.
