LASIK, or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that uses a laser to reshape the cornea of the eye.

The goal of LASIK is to improve the patient’s vision by correcting refractive errors, such as farsightedness, nearsightedness, and astigmatism. While LASIK is a safe and effective treatment for many people, not everyone is a good candidate for the procedure. Here are some factors that may make a person ineligible for LASIK.

Age

One of the most important factors in determining LASIK eligibility is age. LASIK is FDA-approved for individuals aged 18 and older, as the eyes may still change during adolescence.

For patients over the age of 40, presbyopia, or a change in the ability to focus on close objects, may become an issue. While LASIK can correct refractive errors, it cannot prevent or treat presbyopia. Patients over the age of 40 may want to consider alternative treatments, such as monovision LASIK or other refractive surgeries that may better address presbyopia.

Eye Health

Good eye health is essential for LASIK candidacy. Patients with certain eye conditions, such as glaucoma, cataracts, and keratoconus, may not be eligible for LASIK.

These conditions can affect the structure, shape, and clarity of the eye, and may make it difficult for the surgeon to accurately reshape the cornea. Patients with a history of eye infections or inflammation may also be at higher risk for complications after LASIK.

It is important to consult with an ophthalmologist or LASIK surgeon to determine if a patient’s eye health is appropriate for LASIK.

Pregnancy and Breastfeeding

Pregnancy and breastfeeding can affect a woman’s vision in various ways, such as changes in hormones, fluid retention, and dry eye syndrome.

Furthermore, the safety of LASIK during pregnancy and breastfeeding has not been extensively studied, and there is a lack of data on how the procedure may affect the fetus or breast milk. As a precaution, most LASIK surgeons advise women to postpone LASIK until after pregnancy and breastfeeding.

Medications

Certain medications can affect the healing process after LASIK and may increase the risk of complications. Patients who take blood thinners or medications that affect the immune system, such as steroids, may not be eligible for LASIK.

It is important to disclose any medications or supplements to the surgeon and ophthalmologist prior to the procedure.

Occupation and Lifestyle

Individuals who work in certain occupations or have certain lifestyles may not be good candidates for LASIK.

For example, people who work in jobs that involve frequent eye trauma, such as boxing or wrestling, may be at higher risk for postoperative complications. Similarly, individuals who engage in high-impact sports or activities, such as skydiving or scuba diving, may also be at risk for eye injuries after LASIK.

People who have a history of certain eye injuries or surgeries may also be at risk for complications after LASIK.

Stable Prescription

Finally, LASIK is not recommended for people whose vision prescription has recently changed. Patients should have a stable vision prescription for at least one year prior to the procedure to ensure the best possible outcome.

This stability is important because the laser reshapes the cornea based on the patient’s current prescription; if the prescription changes after LASIK, the results may not be optimal.

Conclusion

While LASIK can be a life-changing and highly effective treatment for many people with refractive errors, it is not appropriate for everyone.

To determine if LASIK is right for you, it is important to consult with an experienced ophthalmologist or LASIK surgeon. They can assess your eye health, history, and lifestyle, and recommend the most appropriate course of treatment for your individual needs and goals.
