Am I a Good Candidate for LASIK?

LASIK is an excellent option for many people who want to reduce their dependence on glasses or contact lenses. However, not everyone is a suitable candidate. A successful outcome depends on factors such as eye health, prescription stability, corneal thickness, and overall medical history. A comprehensive eye examination is essential to determine whether LASIK is the safest and most effective choice.

You Have a Stable Vision Prescription

One of the most important requirements is a stable prescription.

Generally, good candidates:

• Have had little or no prescription change for at least 1 year
• Have stable nearsightedness, farsightedness, or astigmatism
• Are not experiencing rapidly changing vision

Stable vision helps improve the accuracy and long-term success of the procedure.

Your Corneas Are Healthy

The cornea must be strong enough to safely undergo laser reshaping.

Your surgeon will evaluate:

• Corneal thickness
• Corneal shape
• Corneal topography
• Signs of conditions such as keratoconus

Healthy corneas are essential for safe LASIK surgery.

Your Eyes Are Free of Serious Disease

Overall eye health plays a major role in determining eligibility.

Good candidates generally do not have:

• Advanced glaucoma
• Cataracts affecting vision
• Active eye infections
• Severe corneal disease

Any existing eye condition will be assessed before surgery.

You Do Not Have Severe Dry Eye

Mild dry eye can often be treated before surgery, but severe cases may require a different approach.

Your evaluation may include:

• Tear production testing
• Tear film quality assessment
• Review of dry eye symptoms

Managing dry eye before surgery improves both comfort and outcomes.

Your Prescription Is Within Treatable Limits

LASIK is effective for many common vision problems.

It is commonly used to correct:

• Nearsightedness (myopia)
• Farsightedness (hyperopia)
• Astigmatism

Very high prescriptions may require alternative procedures such as SMILE or EVO ICL.

Your General Health Supports Healing

Certain medical conditions can affect recovery.

Be sure to discuss:

• Autoimmune disorders
• Diabetes
• Pregnancy or breastfeeding
• Medications that affect healing

A complete medical history helps determine whether LASIK is appropriate.

You Have Realistic Expectations

LASIK can greatly reduce dependence on corrective lenses, but it does not guarantee perfect vision for every patient.

Good candidates understand that:

• Vision may not be perfect without glasses in every situation
• Reading glasses may still be needed with age
• Temporary side effects such as dry eye are common during recovery
• Healing varies from person to person

Realistic expectations contribute to higher patient satisfaction.

You May Not Be a Good Candidate If...

LASIK may not be recommended if you:

• Have an unstable prescription
• Have very thin or irregular corneas
• Have severe dry eye disease
• Have active eye infections or inflammation
• Have certain medical conditions that impair healing

Fortunately, many patients who are not suitable for LASIK may qualify for other vision correction procedures.

What Happens During a LASIK Evaluation?

A comprehensive consultation usually includes:

• Vision and refraction testing
• Corneal thickness measurement
• Corneal mapping (topography)
• Tear film evaluation
• Pupil size assessment
• Dilated eye examination
• Discussion of your lifestyle and visual goals

This evaluation determines both your eligibility and the procedure best suited to your eyes.

Final thoughts

Being a good candidate for LASIK depends on much more than your glasses prescription. Healthy eyes, stable vision, adequate corneal thickness, and realistic expectations all contribute to a safe and successful outcome. A detailed pre-operative examination is the best way to determine whether LASIK is right for you or whether another vision correction option would provide better long-term results.
