When considering LASIK surgery for vision correction, many patients wonder if their vision is too poor for LASIK to restore. Can LASIK correct high prescriptions? This is a question we frequently hear from patients considering the LASIK procedure. At Brinton Vision, our goal is to change as many lives as possible through the gift of sight. This article will answer your questions about high prescriptions and LASIK to help you understand the path available to a life free from contact lenses and glasses.

Can LASIK correct high prescriptions?

Yes, LASIK, or laser-assisted in situ keratomileusis, can often correct high prescriptions, including high degrees of refractive errors, including nearsightedness, farsightedness, and astigmatism. Nearsightedness, or myopia, occurs when your eyes can clearly see objects that are close up but struggle to see objects at a distance. Farsightedness, or hyperopia, is characterized by difficulty in seeing nearby objects clearly, while distant objects appear sharp. Astigmatism refers to a distortion in the eye’s curvature, which leads to blurred vision.

Your eye prescription is measured in diopters, which indicates the degree of correction needed for your eyesight. At Brinton Vision, our team uses state-of-the-art laser technology capable of addressing a range of vision issues. Specifically, LASIK can treat high prescription nearsightedness up to -7.00 diopters, high prescription astigmatism up to 6 diopters, and high prescription farsightedness up to +4.00 diopters. While these are common benchmarks, there is flexibility due to variations in laser strength. So yes, LASIK can correct vision for some patients with high prescriptions.

Consequently, the eligibility for LASIK surgery isn’t solely determined by these numbers. For instance, a person with a -2 diopter prescription might qualify for LASIK, whereas another with a -4 prescription might not. This is because other factors also play a critical role in determining if someone is an ideal candidate for the procedure.

At Brinton Vision, we not only offer LASIK but also its six modern variations so that we are able to find the best vision correction option for your unique needs. To find out if you are a candidate for LASIK schedule your Brinton Vision Ocular Analysis to see how we can help you achieve the visual freedom you deserve.

What method is used to measure eyeglass prescription prior to LASIK surgery?

The eyeglass prescription, also known as your refractive error, is measured in diopters, a term that refers to the lens strength needed to correct your visual acuity. This measurement taken by your ophthalmologist is based on focal length in meters and is determined during your comprehensive eye examination.

A prescription of 0.00 diopters represents what is considered perfect vision. The further away you get from 0.00 the worse your visual perception will be. Diopters are often denoted by “D.” If there’s a + sign before your diopter value, it indicates farsightedness; conversely, a – sign suggests near-sightedness.

What other factors besides the eye prescription determine if someone is a LASIK candidate?

Six considerations beyond just the eye prescription influence whether LASIK is the right choice for an individual. Here are factors that determine eligibility for LASIK eye surgery.

Minimum Age Requirement Individuals under 18 are generally ineligible for LASIK due to ongoing growth and hormonal shifts that can alter eye prescriptions. Undergoing LASIK before reaching 18 is not recommended since the eye prescription may still change, potentially necessitating the need for a corrective procedure again.

Prescription Stability For those over 18, a continuously changing prescription can also hinder suitability for LASIK. LASIK surgeons typically require a stable prescription for 1 to 2 years prior to surgery, ensuring the likelihood of long-lasting results.

Dry Eye Syndrome While having dry eye syndrome doesn’t automatically disqualify you from LASIK, it can complicate recovery. Treatment prior to LASIK with artificial tears and nutritional supplements may be necessary to facilitate healing and a successful LASIK procedure.

Corneal Thickness and Health For LASIK surgery to be safe, it’s important that the patient’s corneas are thick and healthy because the procedure includes making a small flap in the corneal tissue.

Overall Health Considerations Certain health conditions, including glaucoma, cataracts, diabetes, and autoimmune diseases, may elevate the risks associated with LASIK. Other vision correction alternatives may be more suitable for patients with these conditions. Conditions affecting healing, such as strabismus, amblyopia, and keratoconus, or the use of immunosuppressive medications, can also impact LASIK candidacy.

Pregnancy It is advised for pregnant individuals to postpone LASIK until after childbirth, the resumption of menstrual cycles, and/or the cessation of nursing. This recommendation stems from the potential for hormonal changes that affect vision and eye stability. It is highly recommended that you allow hormonal changes in the body to stabilize before proceeding with LASIK surgery.

What are the prescription requirements for LASIK surgery?

Typically, the refractive errors that can be corrected with LASIK include:

  • Up to -7.0 diopters for nearsightedness
  • Up to 6.0 diopters for astigmatism
  • Up to +4.0 diopters for farsightedness

Keep in mind, these standards can differ depending on individual circumstances. Therefore, undergoing a LASIK evaluation with a highly trained eye doctor is crucial to determine if you’re a suitable candidate for the surgery.
