There are no strict limitations for when a person is no longer able to have LASIK. For patients older than 40, the surgeon will have to take into consideration the presence of other age-related eye conditions like cataracts. Should cataracts be a cause of poor vision, the surgeon may consider the option of cataract surgery instead. Via this path, the patient can have their cataracts replaced with a lens implant and potentially be spectacles independent for both near and far distances. In a patient with presbyopia (老花眼), LASIK corrects myopia and astigmatism to enable a patient to see at far distances without glasses. Some modification of the treatment can be done to help reduce the need for reading glasses as well.
