Understanding how LASIK works, what vision regression is, and how the human eye naturally ages helps one better appreciate the risk of vision regression after the procedure. You might find it simpler to accurately imagine the potential advantages and disadvantages of life after LASIK with the help of this information. According to the American Academy of Ophthalmology, LASIK, also known as laser-assisted in situ keratomileusis, is an outpatient refractive procedure that can be used to cure astigmatism, nearsightedness, and far-sightedness. In this treatment, an ophthalmologist carefully removes the required amount of corneal tissue using an excimer laser, thus reshaping the cornea. This permanently alters the cornea’s curvature, enhancing the eye’s capacity to direct light toward the retina and enhancing visual clarity. The standard definition of regression is ‘a return to a previous state’. According to that definition, eyesight regression following LASIK surgery is a myth. By removing tissue from the cornea during LASIK, the eye is permanently altered. Technically speaking, the eye does not regress in the strictest meaning of the word because it is unlikely to return to its prior level of dysfunction. That does not imply that after the treatment, you won’t experience vision changes. Although scientists may have a very specific idea of what regression actually entails, the majority of people worried about the risk of vision regression after LASIK are not anxious that their vision will exactly revert to what it was before the treatment. They are actually worried that their vision would get worse with time. This is possible due to a few factors. There are a few common reasons why it can appear that LASIK’s improvements to vision are regressing: •The progression of nearsightedness or farsightedness. Even though LASIK corrects current nearsightedness or farsightedness, it cannot stop its progression. If your eyes are prone to these issues, they might continue to develop, which could ultimately lead to less-than-ideal vision. •The onset of presbyopia. As with many other body parts, the eyes undergo aging-related changes. The ability of the eye’s lens to concentrate on nearby objects typically starts to deteriorate as people reach their 40s. Presbyopia is what this process is known as, and LASIK does not stop the passage of time to stop it. However, LASIK does not cause the condition’s onset or exacerbate its symptoms.
