Custom Laser Vision Correction

Eyes are like fingerprints. No two are alike and our surgeon and laser team believe your treatment should be customized to your needs.

Custom LASIK allows us to personalize your treatment. In many cases, the result is more than just restored vison – it may actually improve your vision!

Laser Vision Correction: The Technology to See Things Clearer
Custom LASIK uses WaveScan® technology to create a highly detailed map of your vision based on how light is reflected from the back of the eye. This method of measurement is 25 times more precise than standard methods, and this is essential because the information is used to skillfully reshape your cornea using our cool, blade-free laser. The more precise the map, the better the results.

Laser Vision Correction (LVC) is performed using the excimer laser, a computer-controlled, “cool” ultraviolet beam of light. The laser sculpts the cornea into a shape that allows light to focus more directly on the retina, which eliminates or reduces a variety of eye abnormalities.

Envision Eye Care uses a Blade-Free laser technology called IntraLase, which results in safe, incredibly accurate, less invasive procedures and the fastest recovery times.


Below are a list of common questions we recieve about the LASIK. If you have any questions that are not address below please fill out our contact form on the contact page.

Am I a Good Candidate for Laser Vision Correction?

If you …

  • are 21 or older (under certain circumstances, 18 years of age or older)
  • have no systemic illness such as diabetes, glaucoma or rheumatoid arthritis
  • have healthy eyes
  • your prescription is “stable” and has not changed in the past 24 months
  • have realistic expectations about what LASIK can do for your vision.

… then you are likely a good candidate for Laser Vision Correction surgery. However, a thorough eye exam is necessary to confirm this.

What will happen during my consultation?

During your free consultation our ophthalmic technician will measure your prescription by reading your glasses.  Then she will explain the procedure and answer any questions you may have.  You will then have an opportunity to meet the doctor who will be doing your surgery if you choose to move forward. A free consultation is perfect for the person seeking more information about the procedure.

During your LASIK exam (moving forward) you will receive a complete eye examination that includes computer-aided corneal topotgraphy, or a ‘mapping’ of the eye’s surface to determine your corneal shape.  After asking you a series of questions about your lifestyle, including work and leisure vision requirements, your surgeon will discuss options and recommendations for your procedure. 

What side effects can I expect?

For most patients, vision fluctuates for the first few days following the LASIK procedure. Some patients notice glare or halos around lights at night. Some patients experience dry eyes. For most patients these effects are temporary and disappear completely within two weeks of the procedure.


Does LASIK hurt?

This is a commonly asked question. Laser Vision Correction procedures should not cause you any pain. Numbing eye drops will block any painful sensations, and you will be given a mild sedative so that, although you are awake, you won’t feel anything. While your eye may feel a bit scratchy afterwards, no pain medications are usually required and you should be able to return to work or regular activities the next day.

When can I resume normal activity?

For the first night, you must wear protective eye shields to bed. You will not be allowed to swim for about 3 days following your LASIK procedure, but may bathe and shower. The use of eye makeup is restricted for the first 2-3 days as well. Exercise and all other activities are allowed beginning the day after surgery. Your eye care team will want to see you the day following your procedure, and then at intervals of one week and various times during the first year to check on your progress. Our surgeon will determine how often you will need to return depending on your individual situation

What are the risks?

Like all surgical procedures, LASIK does carry some risk, including infection that might damage your cornea or result in some vision loss. However, we want to emphasize that LASIK is approved by the FDA and is one of the most common and safest procedures in the medical field, and complications are rare. During your evaluation with our skilled eye surgeon, you will be provided with a document called Informed Consent, outlining potential risks and complications of your LASIK surgery.
