What to Expect at Your LASIK Consultation and Evaluation
Tests and Measurements During Your Evaluation
Your evaluation involves a series of painless, non-invasive tests that give us a detailed picture of your eye health and the precise measurements needed to plan a safe procedure. Each test plays a specific role in determining your candidacy and personalizing your treatment.
We begin with a thorough examination of the overall health of your eyes using specialized instruments. This exam checks for signs of disease, damage, or conditions that could affect your surgery or your results.
We may use dilating drops to widen your pupils, which allows us to examine the back of your eye more clearly. The drops take roughly 20 to 30 minutes to work, and their effects can last several hours. This is one of the main reasons we ask you to plan for a ride home after your appointment.
Because LASIK works by precisely reshaping the cornea, knowing its exact thickness and shape is essential for safety. These measurements are among the most important we take during your entire evaluation.
- Pachymetry measures the exact thickness of your cornea in microns
- Corneal topography and tomography, including Scheimpflug imaging, create detailed three-dimensional maps of your corneal surface
- These maps help us detect early signs of keratoconus, a condition where the cornea gradually thins and bulges, or other irregularities that could increase your risk
- Epithelial thickness mapping and corneal biomechanics testing may also be used to further evaluate your suitability
All of these tests are completely painless and take only a few minutes to complete.
Knowing your exact prescription is critical for planning an accurate LASIK treatment. During this part of your evaluation, you will look through a series of lenses and indicate which ones give you the clearest view.
We also use automated instruments that measure how light travels through your eye, capturing detailed data about your nearsightedness, farsightedness, and astigmatism. In many cases, we perform wavefront aberrometry, a technology that maps subtle optical imperfections called higher-order aberrations that standard prescriptions do not capture. A cycloplegic refraction, which uses drops to temporarily relax your eye's focusing muscles, may also be performed to give us a more accurate baseline measurement.
Healthy tears are critical for both a comfortable recovery and accurate surgical outcomes. We evaluate the quality and quantity of your tear film before any decision is made about proceeding with LASIK.
- Tests may include tear breakup time, Schirmer testing, osmolarity, MMP-9 assessment, and meibography to evaluate gland health
- If dry eye is found, treatment options include lubricating drops, warm compresses, lid hygiene, anti-inflammatory drops, punctal plugs, or meibomian gland therapies
Optimizing the surface of your eye before surgery improves the precision of your result and your comfort during recovery. In some cases, we may recommend waiting until your dry eye is fully managed before scheduling surgery.
Several other targeted measurements help us assess your candidacy and tailor your treatment plan to your individual eyes.
- Tonometry to check intraocular pressure and screen for glaucoma risk
- Scotopic pupil size measurement to assess the potential for nighttime symptoms such as glare or halos in low light
- Ocular dominance testing to support planning for monovision if it is appropriate for your lifestyle
- Retinal imaging, including optical coherence tomography and digital photography, when clinically indicated
How We Determine Whether LASIK Is Right for You
Not every person is an ideal candidate for LASIK, and part of what makes a thorough consultation so valuable is that it gives us the information needed to protect you. Our LASIK Surgeon reviews every measurement carefully before making any recommendation.
LASIK can correct a wide range of prescriptions, but there are safe limits to what can be effectively treated. Your prescription must fall within certain parameters for LASIK to be a good fit.
In general, LASIK can address nearsightedness up to about negative 12.00 diopters, farsightedness up to about positive 6.00 diopters, and astigmatism up to about 6.00 diopters. A diopter is the unit used to measure refractive error, or how much your eye needs correction. Farsighted treatments above about positive 4.00 diopters tend to carry lower predictability and a higher chance of regression over time. Actual safe limits for your eyes may be narrower based on your corneal measurements, even if a laser's approved range would allow it. If your prescription falls outside these parameters, we will discuss alternatives such as PRK or an implantable lens.
Your cornea must be thick enough to safely allow tissue removal during LASIK. If the cornea is too thin, the procedure could weaken the eye's structure and lead to serious problems later.
- We target a residual stromal bed thickness of at least 250 to 300 microns after treatment
- We also track the percent of tissue altered and aim to keep it below roughly 40 to 45 percent
- Corneal shape must be regular and free of signs associated with ectasia risk, including early keratoconus patterns
- Scarring, irregularities, or borderline thickness may make PRK a safer alternative
We generally recommend that LASIK candidates be at least 18 years old, though waiting until age 21 or older is often preferable because the eyes continue to change during the late teens and early twenties. A prescription that is still shifting can affect how long your results last.
Your prescription should be stable for at least one to two years before surgery. If you are pregnant or nursing, we advise waiting until at least three months after delivery and after nursing has ended, once your prescription has returned to a consistent baseline. Hormonal changes during pregnancy can temporarily alter your refraction and affect the accuracy of any measurement taken during that time.
Certain systemic health conditions and eye-specific conditions can interfere with healing or increase the risk of complications. Our LASIK Surgeon reviews your full history with this in mind.
- Autoimmune diseases such as lupus or rheumatoid arthritis may slow healing or promote inflammation
- Uncontrolled diabetes can affect wound healing and increase infection risk
- Conditions such as keratoconus, severe dry eye, significant blepharitis or ocular rosacea, prior herpetic keratitis, glaucoma, cataracts, or certain retinal problems may make LASIK unsuitable
- A history of keloid scarring or allergies that cause frequent eye rubbing may also factor into the decision
If LASIK is not right for you, we will explain clearly why and discuss procedures such as PRK or an implantable collamer lens that may better serve your needs and your vision goals.
Your LASIK Options and Personalized Treatment Plan
If you are a candidate, your treatment plan will be built around your unique measurements, prescription, and lifestyle goals. Our LASIK Surgeon will walk you through the specific approach best suited to your eyes and help you understand exactly what to expect.
All-laser LASIK, also called bladeless LASIK, uses a femtosecond laser to create the corneal flap rather than a mechanical blade. This approach offers a higher level of precision and consistency in flap creation and has become the standard of care for LASIK procedures.
At The Eye Center, our iLASIK platform uses the IntraLase femtosecond laser to create the flap and the VISX STAR S4 IR excimer laser with 3-D ActiveTrak to perform the actual vision correction. This fully integrated, all-laser system is the same technology approved for use by the US Navy and NASA.
Advanced CustomVue is a personalized treatment approach that maps the unique optical characteristics of your individual eye and uses that data to guide the laser correction. This goes well beyond treating a standard prescription.
- The iDesign 2.0 wavefront system captures a detailed optical fingerprint of your eye, measuring both standard refractive error and subtle higher-order aberrations
- WaveScan WaveFront and Iris Registration technology ensure the treatment is aligned precisely to your eye during surgery
- Custom wavefront-guided treatment may reduce issues such as nighttime glare, halos, and reduced contrast that can occur with non-custom approaches
- Our LASIK Surgeon's proprietary nomogram, refined through more than 40,000 procedures, contributes to our less than 1.5 percent enhancement rate
If your evaluation shows that LASIK is not the safest option for your corneas, photorefractive keratectomy, known as PRK, is often an excellent alternative. PRK corrects vision by reshaping the corneal surface directly without creating a flap, which makes it better suited to patients with thinner corneas or certain corneal surface characteristics.
For very high prescriptions, an EVO Visian ICL, which is an implantable collamer lens placed inside the eye, may be recommended. For patients over 40 who have early cataract changes, refractive lens exchange may be the most appropriate path. We will clearly explain which option gives you the best chance of clear, stable, long-term vision.
Before any decision is made, our LASIK Surgeon will thoroughly review all potential risks and side effects so that your consent is fully informed. Understanding these possibilities is an important part of the process.
- Dry eye symptoms, which are usually temporary but can persist in some patients
- Nighttime glare, halos, and starbursts, which typically improve over weeks to months
- Infection or inflammation requiring prompt treatment
- Flap-related issues in LASIK such as displacement, wrinkling, or epithelial ingrowth
- Corneal ectasia risk in patients with susceptible corneal anatomy
- Undercorrection, overcorrection, or regression that may require an enhancement procedure
- Rare but serious vision-threatening complications
Most people achieve 20/20 or 20/25 vision after LASIK, though individual results depend on your prescription, corneal anatomy, and healing response. We will talk honestly with you about what is realistic for your specific situation.
A small percentage of patients may need an enhancement procedure after their initial healing is complete. Patients over 40 may still need reading glasses after surgery even if distance vision is excellent, because of the natural aging of the eye's focusing ability. We believe honest expectations lead to greater satisfaction with your outcome.
After Your Consultation: Next Steps
Once all your tests are complete and your results have been reviewed, we will guide you clearly through everything that comes next. Whether you are moving forward with surgery or exploring an alternative, we will make sure the path ahead is easy to understand.
Our LASIK Surgeon will sit down with you to go through every test result and explain what it means for your candidacy. You will receive a clear answer about whether LASIK is appropriate for your eyes and why.
If you are a candidate, we will review the informed consent process with you, covering risks, benefits, alternatives, and the specific plan recommended for your eyes. If you are not a candidate for LASIK, we will take the time to explain the reason and discuss the alternatives most likely to help you.
If you decide to move forward, our team will help you select a surgery date that fits your schedule and allows enough time for a comfortable recovery. We recommend choosing a time when you can take at least a day or two off to rest.
- Most patients schedule their surgery within a few weeks of their consultation
- You will need someone to drive you home on the day of surgery
- Plan your first post-operative visit within 24 hours of your procedure
- Avoid scheduling surgery immediately before travel, important events, or demanding professional responsibilities
LASIK is generally considered an elective procedure, and most insurance plans do not cover it. However, there are several ways to make your investment in better vision more manageable.
Many patients use health savings accounts or flexible spending accounts to pay for LASIK with pre-tax dollars. We also work with financing partners that offer payment plans to qualified applicants. Our team will walk you through every available option so you can choose what works best for your situation.
Before your procedure, we will provide detailed written instructions designed to prepare your eyes and reduce any risk of complications. Following these guidelines carefully supports the best possible outcome.
- Stop wearing contact lenses for the required period before surgery
- Avoid eye makeup, lotions, and fragrances on surgery day and for one week after
- Arrange reliable transportation to and from the surgical suite
- Fill any prescribed eye drop prescriptions before your surgery day
- Do not rub your eyes and use protective eye shields while sleeping during the first week
- Avoid getting water directly in your eyes for one week after surgery
- No swimming or hot tubs for at least two weeks
- Limit strenuous exercise for 24 to 48 hours as directed
LASIK is a very safe procedure with a strong track record, but it is important to know which symptoms warrant an immediate call to our office. Do not wait for your scheduled follow-up if you experience any of the following.
- Severe or rapidly worsening eye pain
- Sudden significant drop in vision or increasing redness
- New light sensitivity accompanied by discharge
- Any trauma to the eye or concern that the flap has shifted
- Sudden flashes of light, new floaters, or a dark shadow in your peripheral vision
Frequently Asked Questions
The following questions address common points of uncertainty that many patients have as they prepare for or follow up after a LASIK consultation.
If your pupils are dilated during your evaluation, your near vision will be blurry and your eyes will be sensitive to light for several hours, making it unsafe to drive. We strongly recommend arranging a ride home regardless. If dilation is not needed at your specific appointment, ask our team when you schedule so you can plan accordingly.
Not qualifying for LASIK does not mean vision correction is off the table. Depending on your measurements and health history, PRK, the EVO Visian ICL, or refractive lens exchange may be a suitable and effective alternative. Our LASIK Surgeon will take the time to explain the specific reason LASIK was not recommended and outline which options make the most sense for your eyes and your goals.
The timing is largely up to you and your schedule. Many patients schedule their procedure within one to two weeks of their consultation, while others prefer to take more time to think things through and make arrangements. The most important thing is that you feel fully ready and that the timing allows you to rest properly afterward without rushing back to demanding responsibilities.
You will likely need at least a half day off, particularly if your pupils are dilated. Blurry vision and light sensitivity afterward can make reading, driving, or working on a screen difficult for several hours. It is best to plan for a full afternoon off and avoid scheduling demanding tasks immediately following your appointment.
In the first days to weeks after surgery, it is common to experience dryness, mild irritation, light sensitivity, and nighttime glare or halos around lights. For most patients, these symptoms improve meaningfully within the first few weeks to months as the cornea heals. Consistently using your prescribed lubricating drops and following all post-operative instructions helps minimize discomfort. Severe pain, sudden vision loss, or symptoms that are getting worse rather than better are reasons to contact us right away and not wait for your next scheduled visit.
In most cases, both eyes are treated during the same surgical session. This approach is standard practice and is both convenient and safe when appropriate for your candidacy profile. Our LASIK Surgeon will confirm this during your consultation based on your individual results. In certain circumstances, treating one eye at a time may be recommended, and we will explain the reasoning clearly if that applies to you.
