LASIK is performed to permanently alter the shape of the cornea using laser technology. Only a miniscule amount of corneal tissue is typically removed to create the ideal shape so light focuses more precisely on the retina.
Presbyopia is Not a Refractive Error
The condition of presbyopia (the need for reading glasses or bifocals) is not a refractive error. By age 40, many people start to develop what they might think is farsightedness because they need glasses to read things up-close. Presbyopia is actually the stiffening of the eye lens that occurs naturally over time – even to people who have had 20/20 vision their whole lives. As the lenses become less flexible, it becomes harder to focus on images like text messages, restaurant menus, medicine labels and more without some type of magnifier.
LASIK cannot correct presbyopia. However, a technique called monovision LASIK, where one eye is corrected for vision distance and the other eye is corrected for up-close vision, may be an alternative to reading glasses or bifocals.
While LASIK can help many people achieve clear vision, it is not recommended for everyone.
