LASIK is a type of refractive surgery that uses a laser to reshape the cornea of the eye, improving vision by correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. While LASIK can improve distance vision, it is not generally considered a treatment for presbyopia, which affects the ability to focus on near objects. However, there are some newer variations of LASIK that have been developed specifically to treat presbyopia, including monovision LASIK and blended vision LASIK. These techniques involve deliberately creating a different level of correction in each eye, with one eye corrected for distance vision and the other eye corrected for near vision. This can allow people to have better near vision without glasses or contacts, but it may also cause some loss of depth perception or visual clarity.
