LASIK Candidate: What Determines a Good Candidate?

Wondering If You’re A Good Candidate For LASIK Eye Surgery?

When first considering LASIK, you might wonder if you’re even a candidate for the procedure. Perhaps you worry that your vision is so poor laser vision correction can’t help. Surprisingly, doctors determine your candidacy based on several different factors — not necessarily your prescription. It’s worth visiting a LASIK doctor to discuss the possibilities. Like all medical procedures, this isn’t for everyone. Here’s a rundown of what doctors generally look for.

Basic Requirements For LASIK

There are a few general requirements that apply to everyone. Not meeting these conditions could mean that you are ineligible for LASIK. All patients must:

  • Be at least 18 years of age.
  • Have healthy corneas.
  • Not have an active eye disease.
  • Have at least 20/40 vision with contacts or glasses.
  • Have a stable eyeglass prescription for a specific amount of time.

Your LASIK doctor will do a thorough examination before performing the procedure to assess other factors affecting your candidacy for LASIK.

Who Are the Best Candidates For LASIK Eye Surgery?

Most people with farsightedness, nearsightedness, and astigmatism can expect good results from LASIK if they meet the basic requirements. However, your doctor will also consider these health factors:

  • Corneal and retinal health
  • Eye pressure
  • Past eye diseases
  • Corneal tissue thickness
  • Recent history of ocular herpes
  • Evidence of an autoimmune or collagen vascular disease

Of course, realistic expectations about the outcome are also important. Like all medical procedures, there are potential side effects to consider, such as dry eyes.

Am I Too Old for LASIK?

There is not a set maximum age, but the overall health of your eyes is taken into consideration. For example, if your vision issues are related to a disease like cataracts or glaucoma, then LASIK is not for you. If you are over the age of 40, presbyopia may be at play. This is an age-related matter that many people start to experience in their 40s, when a natural change may occur in your eye’s lens that affects the ability to see up close. This is generally not influenced by refractive surgery.

What to Expect During Your LASIK Evaluation

Your doctor will start out by asking you about a series of health questions, and it is critical to answering each as accurately as possible. You’ll be asked about:

  • Your medical history.
  • Your eye health history.
  • Why you are considering LASIK.
  • A complete list of medications, including herbal supplements and over-the-counter drugs.
  • Your surgical history.
  • Your social history and current lifestyles, such as contact sports and alcohol consumption.
  • Your family history of eye or overall health problems.

Next, you’ll undergo LASIK testing. It’s a painless procedure, performed with sophisticated machines that scan the eye for specific measurements, which the doctor considers in determining your LASIK eligibility. You cannot be properly screened without this part of the evaluation, and the following tests may be done during this process:

  • Dry eye testing to evaluate if pre-procedure treatment is needed to prepare the eyes and reduce risk
  • Pupil testing to see how your reflexes react to light
  • Keratometry to look at the overall shape and radius of your cornea
  • Corneal topography to map the surface curvature of your cornea
  • Contrast sensitivity testing to see how well you differentiate between light and dark
  • Pachymetry to look at the thickness of your cornea
  • Wavefront analysis to measure how light bounces off the back of the eye

Many doctors will do all of this testing in a single visit, so expect to be at the office for two or more hours. It’s best to talk to a LASIK doctor about your eligibility and potential results. It’s worth exploring what LASIK can do for you.

Determining LASIK Candidacy:

Factors Beyond Prescription

When it comes to LASIK candidacy, it’s important to note that doctors consider several factors beyond just your prescription. While your level of refractive error plays a role, other aspects are also taken into account. Factors such as corneal thickness, overall eye health, and the presence of any eye diseases are crucial considerations. Doctors will thoroughly examine your eyes to assess these factors before determining if LASIK is a suitable option for you. So, even if you have a high prescription, it’s still worth visiting a LASIK doctor to discuss your candidacy, as there might be other factors that make you eligible for the procedure.

Who is Eligible for LASIK?

Understanding the Basic Requirements

There are a few general requirements that apply to individuals seeking LASIK. These requirements serve as a baseline to determine if someone is eligible for the procedure. Firstly, you must be at least 18 years old to undergo LASIK. Additionally, having healthy corneas is essential, as they are the primary focus during the surgery. It’s crucial not to have any active eye diseases that could affect the outcome of the procedure. Moreover, having a certain level of vision is necessary, typically at least 20/40 with the help of glasses or contacts. Lastly, having a stable eyeglass prescription for a specific duration is also important. Meeting these basic requirements is an important step towards becoming a LASIK candidate.

LASIK Candidates: What Doctors Look for in Patients

When assessing LASIK candidates, doctors take into account various factors to ensure the best possible outcomes. They will evaluate the overall health of your corneas and retinas, as these are vital for successful LASIK surgery. Eye pressure is also considered to ensure that your eyes are suitable for the procedure. Doctors will inquire about your past eye diseases and evaluate your corneal tissue thickness, as these factors can impact the surgical process. Additionally, they will inquire about any history of ocular herpes or evidence of autoimmune or collagen vascular diseases. By carefully examining these health factors, doctors can determine if you are an ideal candidate for LASIK.

Health Factors Considered for LASIK Eye Surgery Candidates

When considering LASIK, several health factors are taken into account to ensure the safety and success of the procedure. The overall health of your corneas and retinas is crucial, as any abnormalities or diseases can affect the surgical outcome. Eye pressure is assessed to rule out conditions like glaucoma. Doctors will also review your past eye diseases to understand their potential impact on the surgery. Another essential consideration is the thickness of your corneas, as this determines the amount of tissue that can be safely removed during the procedure. Furthermore, any recent history of ocular herpes or the presence of autoimmune or collagen vascular diseases may affect your candidacy. It’s important for doctors to thoroughly evaluate these health factors before proceeding with LASIK surgery.

Realistic Expectations: What to Consider Before LASIK

While LASIK can provide significant vision improvement, it’s essential to have realistic expectations before undergoing the procedure. It’s important to understand that LASIK is not a guaranteed “perfect vision” solution for everyone. While the majority of people with farsightedness, nearsightedness, and astigmatism can expect positive results, individual outcomes may vary. Additionally, it’s crucial to be aware of potential side effects, such as dry eyes, that can occur after LASIK. By having realistic expectations and being aware of the potential risks, you can make an informed decision and have a more positive LASIK experience.

Age and LASIK: Is There a Maximum Age Limit?

LASIK does not have a set maximum age limit. Instead, the overall health of your eyes becomes a more important factor. If you are experiencing vision issues related to conditions like cataracts or glaucoma, LASIK may not be the suitable solution. Additionally, individuals over the age of 40 may experience presbyopia, which is a natural change in the eye’s lens that affects near vision. Presbyopia is generally not influenced by refractive surgery like LASIK. However, age alone does not disqualify someone from being a LASIK candidate. It’s important to consult with a LASIK doctor who can evaluate your eye health and provide personalized recommendations based on your specific circumstances.
