What Causes Lasik to Regress? An Expert's Perspective

This blog post explains what causes lasik regression and why the risk is extremely low. It also clarifies the difference between deterioration due to lasik and age-related deterioration in vision.

What Causes Lasik to Regress? An Expert's Perspective

It is well known that refractive regression after LASIK is mainly caused by corneal protrusion, rather than postoperative central corneal thickening or RBT. Studies have indicated that myopic regression after LASIK is correlated with low RBT prior to the surgery. Presbyopia may be the source of the misconception that vision regression after LASIK is normal. If a patient who has undergone LASIK needs to wear eyeglasses again, presbyopia is likely to be the cause. Presbyopia is an age-related decline in vision that is unavoidable and cannot be prevented, even with LASIK.

Despite the fear that overworking close to work after LASIK surgery, such as using a computer, could lead to regression, there is no reliable evidence of this. Even if a person still has good vision after LASIK surgery, they will likely need reading glasses as they age in order to see nearby objects. While scientists may have an exact understanding of what regression means, most people who are concerned about the possibility of vision regression after LASIK are not worried that their vision will return to exactly what it was before the procedure. In some cases, after LASIK or PRK, people who experience mild refractive changes are not affected by the adjustment and do not feel the need for additional vision correction. This blog post explains the causes of vision regression after LASIK, why the risk is extremely low, and clarifies the difference between that deterioration and age-related deterioration in vision. For those at a greater risk of regression, such as those with very high power glasses prior to surgery, LASIK combined with simultaneous corneal cross-linking treatment can help keep the power of the glasses stable after LASIK.

Foulkes Vision has performed more than 48,000 LASIK surgeries throughout his career, so patients can be sure that they will get it right the first time. This is also why LASIK surgery isn't performed on children since their power of their glasses is usually not stable yet. In these cases, some people who underwent LASIK misinterpreted the symptoms of presbyopia as a sign that the effects of LASIK had worn off over time.


, which stands for laser in situ keratomileusis, is a common surgery that can correct vision in people who are nearsighted or farsighted or have astigmatism. It should be noted that LASIK is a permanent surgery that removes tissue from the cornea and therefore technically cannot return eyes to their original state.

Crosslinking corneal collagen with LASIK or SMILE is relatively new and its true beneficial effects may not be quantified or known for a few years. Additionally, since LASIK involves remodeling the cornea which is located in front of the lens, it cannot affect the lens. The Mayo Clinic points out that Lasik removes tissue from the cornea and causes permanent changes in the eye. Therefore, anyone considering a serious medical procedure such as Lasik should carefully weigh all pros and cons beforehand.
