What to Expect at Your LASIK Consultation and Evaluation
Preparing for Your LASIK Consultation
A little preparation before your visit goes a long way toward ensuring our LASIK Surgeons get the most accurate measurements possible. Knowing what to bring, what to avoid, and what to share helps us give you the most thorough evaluation from the moment you arrive.
Coming prepared with the right items helps our team complete your evaluation efficiently and accurately.
- Your current eyeglasses and most recent eyeglass or contact lens prescriptions
- Sunglasses to wear after pupil dilation, which temporarily blurs vision and increases light sensitivity
- A contact lens case and solution if you wear contacts
- A complete list of all medications, vitamins, and supplements you take
- Your insurance card and a valid photo ID
- A written list of questions you want to ask our LASIK Surgeon
Please plan to wear your glasses on the day of your consultation rather than your contact lenses, unless you have been told otherwise.
Most LASIK consultations last between one and two hours. We recommend budgeting at least two hours so you do not feel rushed through any of the tests or the discussion with your LASIK Surgeon.
Because pupil dilation can blur your vision for several hours afterward, we strongly encourage you to arrange a ride home rather than planning to drive yourself.
Contact lenses can temporarily change the shape of your cornea, the clear front surface of the eye, which may lead to inaccurate measurements. Stopping contact wear before your consultation is essential for reliable results.
- Soft daily wear lenses: stop wearing them 3 to 7 days before your appointment
- Soft toric or extended-wear lenses: stop at least 2 weeks before
- Rigid gas permeable lenses: stop 3 to 4 weeks before, or longer depending on how many years you have worn them
- Scleral lenses: stop at least 4 weeks before, and we will confirm the exact timeline with you
Always follow the specific guidance from your LASIK Surgeon, as individual circumstances may require a longer contact-free period.
Certain health conditions and medications can affect whether LASIK is safe or appropriate for you. Being open and thorough about your medical background helps our team make the safest recommendations possible.
- Medications for anxiety, depression, or chronic pain management
- Any history of autoimmune conditions such as rheumatoid arthritis or lupus
- Diabetes, thyroid disorders, or hormonal imbalances
- Current or recent pregnancy, nursing, or plans to become pregnant soon
- Prior eye surgeries, eye injuries, or recurring eye infections
- Medications such as isotretinoin, amiodarone, topiramate, or systemic immunosuppressants
Your consultation is your opportunity to get honest, detailed answers from our LASIK Surgeon before making any decision. Writing your questions down ahead of time ensures you do not forget anything important during the visit.
Common questions include asking about recovery time, realistic vision outcomes, long-term results, potential risks, and what happens if your vision changes in the future. There is no such thing as a question that is too small or too basic. We encourage you to ask about anything that is on your mind.
Tests and Measurements During Your Evaluation
Your evaluation involves a series of painless, highly precise tests that give our LASIK Surgeons a detailed picture of your eye health and vision. Each measurement plays a specific role in determining whether you are a candidate and, if so, how your treatment should be personalized.
We begin with a thorough examination of the overall health of your eyes using specialized instruments. This exam looks for signs of disease, prior damage, or conditions that might affect your surgical outcome.
We may use dilating drops to widen your pupils so we can see the back of your eye more clearly. These drops take approximately 20 to 30 minutes to take full effect and may cause blurry vision and light sensitivity for several hours afterward, which is why a ride home is so important.
One of the most critical parts of your evaluation measures the thickness and shape of your cornea. Because LASIK reshapes the cornea to correct your vision, we need to confirm that your corneas are thick enough and have a healthy, regular shape before proceeding.
- A pachymeter measures corneal thickness in microns, the unit used to evaluate how much tissue can safely be treated
- Corneal topography and tomography, including Scheimpflug imaging, create detailed three-dimensional maps of your corneal surface
- These maps help detect early signs of keratoconus, a condition where the cornea gradually thins and bulges, or other irregularities that would increase the risk of complications
- Epithelial thickness mapping and corneal biomechanics assessments may also be used to further evaluate your risk profile
All of these scans are completely painless and take only a few minutes to complete.
Knowing your exact prescription is essential for planning your LASIK treatment. During refraction testing, you will look through a series of lenses and identify which ones provide the clearest vision. Automated instruments also measure how light enters your eye to give us precise data on your level of nearsightedness, farsightedness, and astigmatism.
Our LASIK Surgeons may also perform cycloplegic refraction, which temporarily relaxes the eye's focusing muscles for a more accurate reading, and wavefront aberrometry, which maps subtle optical imperfections in your eye called higher-order aberrations that standard prescriptions do not capture.
Several additional measurements help us assess your candidacy and customize your treatment plan.
- Tonometry measures the pressure inside your eye and helps screen for glaucoma risk
- Scotopic, or low-light, pupil size measurement helps assess your risk for night vision disturbances after surgery
- Ocular dominance testing identifies which eye your brain relies on most, which is especially useful if monovision or blended vision is being considered
Healthy, stable tears are essential for comfortable healing after LASIK and for getting accurate pre-surgical measurements. We evaluate both the quality and quantity of your tear film to identify any existing dry eye before surgery.
- Tests may include tear breakup time, Schirmer testing, tear osmolarity, MMP-9 testing, and meibography, which images the oil-producing glands in your eyelids
- If dry eye is detected, pre-treatment options may include lubricating drops, warm compresses, anti-inflammatory drops, punctal plugs, or meibomian gland therapies
Optimizing your tear film before surgery improves both the accuracy of your measurements and the comfort of your recovery. In some cases, we may recommend waiting until your dry eye is well-managed before scheduling surgery.
When clinically appropriate, we use advanced imaging to photograph the inside of your eye, including the retina and optic nerve. These images help us identify any concerns that may not be visible during a standard exam.
- Optical coherence tomography provides detailed cross-sectional images of your retinal layers
- Digital retinal photography creates a baseline record of your eye health
- These scans are quick, painless, and require no direct contact with your eye
Determining Whether You Are a LASIK Candidate
After completing all measurements, our LASIK Surgeons review the full picture of your eye health, prescription, and medical history together. Candidacy depends on several interconnected factors, and understanding each one helps explain the recommendation you receive.
LASIK can correct a broad range of vision problems, but every laser platform has safe treatment limits. Our LASIK Surgeons can typically address nearsightedness up to approximately negative 12.00 diopters, a unit used to measure the strength of a lens prescription, farsightedness up to about positive 6.00 diopters, and astigmatism up to about 6.00 diopters.
Farsighted treatments above positive 4.00 diopters tend to have lower predictability and a greater chance of regression over time. Individual corneal measurements may further narrow what is safely treatable, even if a prescription technically falls within a laser's approved range. If your prescription falls outside safe limits, we may recommend PRK or an implantable lens instead.
Your corneas must be thick enough to allow the safe removal of tissue during LASIK without compromising the structural integrity of the eye.
- We evaluate residual stromal bed thickness, targeting at least 250 to 300 microns of corneal tissue remaining after treatment
- We also monitor percent tissue altered and generally aim to stay below approximately 40 to 45 percent
- Corneal maps must show a regular shape without signs of keratoconus or other conditions that raise ectasia risk, where the cornea progressively weakens after surgery
- Any significant scarring, thinning, or irregular shape may make PRK a safer choice than LASIK
We generally recommend that LASIK candidates be at least 18 years old, though waiting until 21 or older is often preferred. Vision continues to develop and shift during the late teens and early twenties, and surgery performed during this period may not hold its results as long.
Your prescription should be stable for at least one to two years before surgery. If your vision is still changing, we may recommend waiting until it has settled. If you are pregnant or nursing, we advise postponing LASIK until at least three months after delivery and after nursing has ended, as hormonal changes during this period can temporarily affect your prescription.
Certain systemic and eye-specific conditions can influence healing, increase complication risk, or make LASIK less appropriate as a treatment choice.
- Autoimmune diseases such as lupus or rheumatoid arthritis may impair healing and increase the risk of inflammation
- Uncontrolled diabetes can affect wound healing and infection resistance
- Conditions such as keratoconus, severe dry eye, certain retinal problems, prior herpetic keratitis (a viral infection of the cornea), or significant blepharitis may rule out LASIK
- A history of keloid scarring or poorly controlled allergies that lead to frequent eye rubbing may also raise concerns
If LASIK is not the right fit, our LASIK Surgeons will explain why and guide you toward an alternative that may be safer and more effective for your specific situation.
Understanding Your LASIK Options and Recommendations
If you are a candidate, our LASIK Surgeons will explain the technologies and treatment approaches that best match your eyes and lifestyle. We use advanced laser platforms to deliver precise, personalized results and will only recommend a treatment that we believe is genuinely appropriate for you.
Bladeless LASIK, also called all-laser LASIK, uses a femtosecond laser to create the thin corneal flap that is lifted during the procedure, rather than a surgical blade. This approach offers greater precision and consistency in flap creation and has become the standard of care.
Our practice uses the Alcon WaveLight FS200 Femtosecond Laser, one of the fastest and most precise platforms available, to create highly uniform flaps with a reduced risk of flap-related complications. Our LASIK Surgeons will explain which technology is most appropriate for your eyes during your consultation.
Custom LASIK treatments go beyond correcting your standard prescription by addressing the unique optical imperfections specific to your individual eye. Wavefront aberrometry maps how light travels through your entire optical system, capturing subtle distortions called higher-order aberrations that standard prescriptions do not account for.
- Custom treatments may reduce the risk of night glare, halos, and starbursts after surgery
- Topography-guided treatments use detailed corneal maps to minimize vision distortions and are particularly useful for eyes with irregular corneal surfaces
- Wavefront-optimized treatments help preserve the natural shape of the cornea to reduce induced aberrations
- We use the VISX STAR S4 and Allegretto Wave excimer laser systems to deliver fully personalized corneal reshaping
Our LASIK Surgeons will recommend the specific treatment approach that gives you the best potential outcome based on your measurements.
If your evaluation shows that LASIK is not the safest option for your eyes, we may recommend photorefractive keratectomy, or PRK. PRK reshapes the cornea using the same advanced laser technology as LASIK but without creating a flap, making it a strong choice for patients with thinner corneas or those involved in contact sports or high-risk physical activities where a flap could be displaced.
Other alternatives include implantable collamer lenses for very high prescriptions or refractive lens exchange for patients over 40 who may also have early cataracts. Our goal is always to match you with the procedure that offers the safest and most effective path to clearer vision.
Before you make any decision, your LASIK Surgeon will thoroughly review both the potential risks and what you can realistically expect from your results.
- Dry eye symptoms are common in the weeks after surgery and are usually temporary, though they can persist in some patients
- Night glare, halos, and starbursts around lights typically improve significantly within the first few weeks to months of healing
- Undercorrection, overcorrection, or prescription regression may occasionally require an enhancement procedure
- Less common risks include infection, inflammation, flap-related issues such as displacement or epithelial ingrowth, and corneal ectasia in predisposed corneas
Most patients achieve 20/20 or better vision after LASIK, but individual results depend on your prescription and eye health. Some patients may still need reading glasses after age 40, and a small percentage may benefit from an enhancement later. Honest, realistic expectations are a foundation of what we discuss with every patient.
After Your Consultation: Next Steps
Once all testing is complete, your LASIK Surgeon will sit with you and walk through your results in plain language. Whether you are moving forward with surgery or exploring other options, we make sure you leave your consultation with a clear understanding of your path forward.
Your LASIK Surgeon will explain what each measurement means and whether you are a good candidate for LASIK or another procedure. If you are a candidate, we will describe the procedure in detail, review the informed consent process including risks, benefits, and alternatives, and outline a personalized treatment plan.
If LASIK is not right for you, we will explain exactly why and discuss alternative options that may be more appropriate. No one is ever pressured to make a decision on the same day.
If you decide to move forward, our team will help you choose a surgery date that fits your schedule. We generally recommend selecting a time when you can take at least one to two days off work to rest and recover.
- Most patients schedule their surgery within a few weeks of their consultation
- You will need someone to drive you home on surgery day
- Plan your first follow-up visit within 24 hours of your procedure
- Avoid scheduling surgery immediately before important events or travel
Because LASIK is considered an elective procedure, most insurance plans do not cover the cost. However, there are several ways to make the investment more manageable.
Many patients use health savings accounts or flexible spending accounts, which allow you to pay with pre-tax dollars. We also work with financing companies that offer low- or no-interest payment plans. Our team will walk you through all available options and help you find a solution that fits your budget.
Before your surgery, we will provide detailed written instructions to help you prepare. Following these carefully reduces your risk of complications and supports the best possible outcome.
- Stop wearing contact lenses for the required period before your surgery date
- Avoid eye makeup, lotions, and perfumes on the day of surgery and for one week following
- Arrange transportation to and from the surgical center
- Fill any prescribed eye drop prescriptions in advance so they are ready to use immediately after surgery
- Do not rub your eyes, and use the protective shields provided while sleeping for the first week
- Avoid getting water directly in your eyes for one week, and skip swimming or hot tubs for at least two weeks
- Limit strenuous physical activity for 24 to 48 hours as directed by your surgeon
LASIK is a safe and well-established procedure, but you should contact our office right away if you notice any of the following warning signs after your consultation or surgery.
- Severe or worsening eye pain that is not relieved by prescribed drops
- A sudden decrease in vision or rapidly increasing redness
- New light sensitivity accompanied by discharge
- Any trauma to the eye or concern that the flap may have been displaced
- Sudden onset of flashes, new floaters, or a dark shadow or curtain across any part of your vision
These symptoms warrant prompt evaluation and should never be ignored or left until a scheduled follow-up.
Frequently Asked Questions
Here are answers to some of the most common questions patients have about the LASIK consultation process. These are intended to add practical guidance that goes beyond what is already covered above.
It depends on whether your pupils are dilated during the visit. If dilation drops are used, your vision will be blurry and you will be very sensitive to light for several hours, making driving unsafe. We recommend confirming with our scheduling team whether dilation is planned so you can arrange a ride in advance. If dilation is not needed for your specific evaluation, driving yourself may be fine, but it is always better to plan ahead.
Not qualifying for LASIK does not mean you have no options. Many patients who are not ideal LASIK candidates do very well with PRK, implantable collamer lenses, or refractive lens exchange. Our LASIK Surgeons will explain exactly which factors ruled out LASIK and which alternative would give you the safest, most effective result. In some cases, treating an underlying condition like dry eye first may eventually make you a candidate.
Many patients schedule surgery within one to two weeks of their consultation, while others prefer more time to consider their options or arrange time off work. There is no pressure to move quickly. What matters most is that you feel fully informed and ready before your surgery date. Our team will work around your schedule and answer any lingering questions before you commit.
Plan to take at least half a day off, especially if your pupils will be dilated. Blurry vision after dilation makes reading, screen use, and focused tasks difficult for several hours. A full afternoon off is the safest approach, and you should avoid scheduling any demanding work tasks immediately following your appointment.
LASIK produces long-lasting results for most patients, but the eyes can continue to change naturally with age. If your vision shifts significantly after surgery, an enhancement procedure may be an option depending on how much corneal tissue remains. The natural development of presbyopia, the age-related loss of near focusing ability, is a separate and expected process that LASIK does not prevent. Your LASIK Surgeon will discuss realistic long-term expectations as part of your consultation.
Not always. The initial consultation establishes whether you are a candidate and gives you the information to make a decision. If you decide to proceed, a separate pre-operative appointment is typically scheduled closer to your surgery date to confirm measurements, review instructions, and finalize your treatment plan. Our team will clearly outline the timeline and what each visit involves so there are no surprises.
