LASIK is a permanent surgical procedure that changes your cornea’s shape to help make your vision clear without glasses or contact lenses. Sometimes, you may need secondary or enhanced surgery after the initial LASIK procedure. Generally, there is no limit to the number of LASIK procedures you can undergo in your lifetime.
Several factors influence whether or not you are a good candidate for enhanced surgery. Corneal thickness is one of the main determinants of the safety of multiple LASIK surgeries.
Other health aspects and personal factors will also need to be considered. For example, your eyes will change according to your age, which may cause the prescription and correction made with the initial LASIK surgery to change. It can affect the clarity of vision and may be a factor in considering secondary LASIK surgery to correct it.
Most patients can opt for LASIK surgery multiple times. The answer to “How many times can you have LASIK?” Because most doctors choose to perform LASIK on patients over 18 whose prescription has stabilized, so most LASIK candidates do not need further LASIK treatment. It is because their vision will not undergo many changes after surgery. This fact applies especially to patients over 40 years of age.
For the less percentage of clients whose vision changes after LASIK, procedures such as PRK after LASIK are available.
Additionally, doctors should warn patients with high prescriptions that they are more likely to need additional treatment long before surgery. (If you’re worried you might fall into the latter category, check out our post “Is My Vision Too Bad for LASIK?”.)
Can LASIK be repeated years later?
LASIK can be done again from the end of the standard LASIK recovery period to after some years of surgery. So, how many times you can have LASIK will depend on your health and corneal thickness.
Whether you anticipate needing another LASIK or a LASIK enhancement, follow all best practices in preparation for LASIK. Post-op care increases the likelihood of a successful first and second surgery during your LASIK surgery.
Is LASIK safe in the long term? Can Your Vision Get Worse After LASIK?
The effects of LASIK surgery are permanent. Your LASIK cannot “wear out.” Sometimes, the health of your eye can change, which in turn can reduce the effectiveness of your LASIK. The significant eye changes occur independently of your LASIK procedure—meaning they would likely happen whether or not you choose to have LASIK.
For example, many people experience presbyopia (hardening of the eye’s lens) as their eyes age and when they start wearing reading glasses to compensate for presbyopia-related vision loss. (Good news! Presbyopia, also known as nearsightedness, can be treated.)
