LASIK Consultation: What Happens and How to Prepare

Not medical advice. This guide helps you understand the consultation process so you can participate as an informed patient.

What is a LASIK consultation?

A LASIK consultation is a comprehensive eye examination combined with a candidacy evaluation. It is more thorough than a routine eye exam. The surgeon’s team assesses whether your eyes are suitable for LASIK, determines your prescription, maps your corneal structure, evaluates your tear film, and discusses your goals and expectations.

Think of it as a two-way evaluation: the surgeon is determining whether LASIK is safe and effective for you, and you are determining whether this surgeon and center meet your standards.

How long does it take?

Plan for 1.5 to 3 hours. The variation depends on:

• How many diagnostic tests are performed
• Whether dilation is included (which adds waiting time)
• How thorough the surgeon is with the discussion portion
• Whether you meet with both a technician and the surgeon

Some centers split the evaluation into two visits: an initial screening with a technician, followed by a surgeon consultation. Others complete everything in one appointment.

What to do before your consultation

Stop contact lenses on schedule

Contacts reshape the cornea temporarily, which can skew measurements. Typical timelines:

• Soft disposable lenses: 5-7 days before the appointment
• Soft toric lenses: 1-2 weeks before
• Rigid gas permeable (RGP) lenses: 3-4 weeks before
• Hard lenses: 4+ weeks before

If you forget or cannot stop in time, tell the staff. They may still proceed with some tests but will likely ask you to return for corneal measurements after a contact-free period.

Bring your records

Come prepared with:

• Your current glasses or contacts prescription (and older ones if available, to show stability)
• A list of all medications, including over-the-counter supplements
• Any previous eye surgery records or specialist letters
• Your health insurance card (even though LASIK is typically not covered, some testing may be billable)

Write down your questions

You will have time to ask questions, but it is easy to forget them in the moment. Common topics worth asking about:

• Which procedure is recommended for your eyes (LASIK, PRK, SMILE, ICL) and why
• The surgeon’s experience and complication rate
• Enhancement policies and warranties
• What results to realistically expect
• Total cost, including follow-up care

For a full question list, see Top Questions to Ask at Your LASIK Consultation.

Diagnostic tests performed

The consultation involves a battery of measurements and tests. Here is what each does and why it matters.

Autorefraction and manifest refraction

What it is: Autorefraction is a machine-based estimate of your prescription. Manifest refraction is the “which is better, one or two?” test where the doctor dials in your exact correction.

Why it matters: This determines the refractive error the laser will correct. Accuracy here directly affects your outcome.

Corneal topography

What it is: A device maps the curvature of your corneal surface using reflected light rings or scanning technology.

Why it matters: Topography reveals irregular astigmatism, keratoconus, and other surface abnormalities that could disqualify you from LASIK or change the approach.

Corneal tomography (Pentacam, Galilei, or similar)

What it is: A more advanced scan that images the front and back surfaces of the cornea plus its internal structure. A Scheimpflug camera captures a cross-sectional view.

Why it matters: Tomography detects early keratoconus and subtle corneal thinning that topography alone might miss. It is now considered standard of care for LASIK screening.

Pachymetry

What it is: Measures corneal thickness, typically at the thinnest point.

Why it matters: Enough corneal tissue must remain after flap creation and laser ablation to maintain structural integrity. Thin corneas may need PRK or an alternative procedure.

Wavefront analysis

What it is: An aberrometer maps how light travels through your entire optical system, detecting higher-order aberrations beyond simple nearsightedness, farsightedness, and astigmatism.

Why it matters: Wavefront data can guide a custom (wavefront-optimized or wavefront-guided) laser treatment, potentially improving night vision quality and reducing halos.

Pupil size measurement

What it is: Pupil diameter is measured in dim lighting conditions.

Why it matters: Patients with very large pupils may have a higher risk of night vision symptoms (halos, glare) if the treatment zone does not cover the full dilated pupil. Modern lasers have largely addressed this with larger treatment zones, but it remains a relevant measurement.

Tear film evaluation

What it is: Tests may include tear break-up time (TBUT), Schirmer’s test (tear volume), and ocular surface staining with dyes.

Why it matters: Pre-existing dry eye should be managed before surgery. Untreated dryness can affect measurement accuracy and worsen after LASIK.

Dilated fundus exam

What it is: Drops are used to widen the pupil so the surgeon can examine the retina, optic nerve, and vitreous.

Why it matters: Peripheral retinal holes or tears should be treated before LASIK. The exam also checks for other conditions like glaucoma or macular abnormalities.

Questions the surgeon will ask you

Expect to discuss:

• Your vision goals: Do you want distance vision, reading vision, or a monovision blend? Do you drive at night frequently?
• Your occupation: Screen-heavy jobs, outdoor work, and precision tasks each inform recommendations.
• Your sports and hobbies: Contact sports may point toward PRK or SMILE. See LASIK and Sports: When You Can Return and What Changes.
• Your medical history: Autoimmune conditions, diabetes, medications (especially isotretinoin, immunosuppressants), and pregnancy status all matter.
• Your eye history: Previous eye surgeries, injuries, infections, or conditions like amblyopia (lazy eye).
• Your expectations: The surgeon needs to know what you consider a successful outcome so they can set realistic expectations.

How to evaluate what you are told

Signs of a thorough consultation

• The surgeon (not just a technician) reviews your results with you in person.
• Multiple diagnostic tests are performed, not just autorefraction and a brief exam.
• The surgeon discusses both the benefits and limitations of LASIK for your specific eyes.
• Alternative procedures are mentioned if they might be more appropriate.
• You are not pressured to schedule surgery immediately.
• Questions are answered directly, not deflected.

Red flags

• High-pressure sales tactics: “This special price expires today” or “We can schedule you for next week” before completing a full evaluation.
• Minimal testing: A consultation that takes 20 minutes and involves only a refraction and brief corneal scan is likely inadequate.
• Guaranteed perfect outcomes: No ethical surgeon guarantees 20/20 vision. They should discuss realistic ranges and the possibility of enhancement.
• Unwillingness to discuss alternatives: If LASIK is presented as the only option without mention of PRK, SMILE, or ICL when your eyes might benefit from them.
• No surgeon face time: If you never meet the surgeon who will operate on you, that is a concern.
• Below-market pricing without explanation: Extremely low prices may indicate older technology, lower surgeon volume, or limited follow-up care.

Free consultations vs. paid evaluations

Many LASIK centers offer free consultations as a way to attract patients. Others charge a fee (typically $50-$250), sometimes applied toward the surgery cost.

Free consultations are common and do not inherently indicate lower quality. However, evaluate whether the free consultation includes all the diagnostic tests described above. Some free screenings are abbreviated assessments with the full workup deferred to a second visit.

Paid consultations are often more comprehensive from the start. The fee may also discourage tire-kickers, meaning the surgeon can spend more time with patients who are seriously considering the procedure.

Either model can work well. What matters is the thoroughness of the evaluation and the quality of the surgeon interaction, not whether you paid for the visit.

Timeline from consultation to surgery

Some patients are scheduled within a week of their consultation. Others wait several weeks, especially if additional contact lens discontinuation time is needed or if dry eye requires pre-treatment.

There is no rush. A surgeon who encourages you to take time to decide is generally preferable to one who pushes for immediate booking.

Getting a second opinion

If anything about your consultation felt unclear, rushed, or uncertain, consider a second opinion. Different surgeons may recommend different approaches, and comparing perspectives helps you make a confident decision. See Second Opinion Before LASIK: When and How to Get One for guidance.

Bottom line

A LASIK consultation is your opportunity to gather data about your own eyes and evaluate the surgeon and center. Come prepared with questions and your medical history, expect a comprehensive battery of tests, and watch for both green flags (thoroughness, transparency) and red flags (pressure, minimal testing, guaranteed outcomes). A good consultation leaves you informed and confident, not rushed.
