What is LASIK?

LASIK, which reduces or eliminates a person’s dependency on glasses or contact lenses, has quickly become the refractive procedure of choice for most patients. They recover quickly, have fewer side effects and complications than with other procedures, and often notice a significant improvement in their vision soon after surgery. LASIK corrects refractive errors by reshaping or flattening the curve of the cornea, the clear layer of tissue covering the front of the eye. First, a thin flap is made on the cornea using a femtosecond laser. The flap is carefully pulled back, and the cornea is reshaped using precise short pulses of ultraviolet light from an excimer laser. The flap is then smoothed back to its original position. The entire procedure takes just a few minutes. LASIK is used to treat nearsightedness, farsightedness, and astigmatism. We perform thorough testing to determine if our patients are good candidates for vision correction surgery.

Ideal LASIK Candidates are those patients who:

  • Are at least 18 years of age
  • Have a stable refraction
  • Have no other ocular health issues
  • Have normal corneal thickness and curvature

What does LASIK Correct?

In order for our eyes to be able to see, light rays must be bent or refracted by the cornea and the lens so they may focus on the retina, the tissue that lines the back of the eye. The retina receives the pictures formed by these light rays and sends the image to the brain through the optic nerve. A refractive error means that the shape of the eye does not refract the light properly, resulting in a blurred image. Intervention in the form of glasses, contact lenses, or refractive surgery is needed to alter the light rays and make them focus on the retina properly. Although refractive errors are called eye disorders, they are not diseases.

What are the different types of refractive errors?

Myopia (Nearsightedness)

A myopic eye is longer than average or has a cornea that is too steep, causing the light rays to focus in front of the retina. Close objects appear clear, but distant objects are blurred. Myopia may be inherited and is often discovered in children between 8 and 12 years old. During school-age years, when the body grows rapidly, myopia may increase. Between the ages of 20 and 40, however, there is usually little change. Patients with high myopia have an increased risk of retinal detachment due to the eye’s longer shape. Your eye doctor should discuss this risk with you, along with the warning signs of a retinal detachment. Having LASIK or another refractive procedure will not reduce this risk, as the eye remains elongated after surgery. It is important to have regular eye examinations to monitor for any changes in the retina. Myopia Refractive Error

Hyperopia (Farsightedness)

A hyperopic eye is shorter than average or has a cornea that is too flat, causing the light rays to focus beyond the retina. Near objects appear blurred, and sometimes distant objects are blurred as well. Like myopia, hyperopia is often inherited. Babies and young children tend to be slightly hyperopic, but as the eye grows longer, hyperopia lessens. This is why some people wear reading glasses as a young child and then grow out of them as they get older. Hyperopia Refractive Error


Astigmatism refers to an irregular shape of either the cornea, the clear covering on the front of the eye, or of the lens inside the eye. This irregular curvature causes light to focus improperly on the retina, and vision may become blurred at any distance. Astigmatism is very common, and most people have some degree of astigmatism. Slight amounts may not affect vision, but larger amounts may cause blurred or distorted vision, eye fatigue, and headaches. Astigmatism is often inherited and present at birth, though it may change over time. It is possible to have astigmatism combined with hyperopia or myopia. Astigmatism Refractive Error


Presbyopia occurs when the natural lens inside the eye loses its flexibility, making it difficult to focus on objects up close. This is a gradual process that takes place over many years, though presbyopia usually becomes noticeable in the early to mid-40s. Presbyopia is a natural part of the eye’s aging process and cannot be prevented. It may be combined with other refractive errors, including myopia, hyperopia, or astigmatism.

Monovision Correction

Monovision is a treatment technique used for patients aged 40 or older who are affected by presbyopia. Presbyopia occurs when the lens inside the eye naturally loses its ability to focus on objects up close. With monovision, one eye is focused to see clearly at distance, and the other eye is focused to see clearly at near. The brain learns which eye to use, depending on whether you are focusing on a distant or near object. Often times, monovision is implemented with contact lenses, but it can also be done with refractive surgery, such as LASIK, or with cataract surgery. It is important to understand that monovision may not be the best option for everyone. You should discuss this option thoroughly with one of our doctors to determine if you would benefit from monovision correction. We generally recommend a brief trial period with contact lenses to be sure you are comfortable with monovision correction before proceeding with LASIK.

Common Questions About LASIK Eye Surgery

At Diagnostic Eye Center, we want you to have all of your questions answered before proceeding with any type of surgery. If you have a LASIK question that is not answered on our website, please feel free to ask your doctor during your consultation.

How good will my vision be after LASIK?

Most of our patients can expect to have 20/20 vision after LASIK surgery and many will have better than 20/20 vision. Each patient’s results depend on multiple factors, including the level of vision prior to surgery. Our doctors use the best technology available so that patients can achieve an optimal result. Your doctor will discuss what result you can expect at the time of your consultation.

How many LASIK procedures have Dr. Sanders and Dr. Salem performed?

Our doctors have collectively performed over 10,000 refractive procedures. Dr. Sanders has been performing laser vision correction since it was first approved over a decade ago and has performed LASIK on many of his physician colleagues and on local and national celebrities. Learn more about Dr. Sanders and Dr. Salem.

Is LASIK affordable?

At Diagnostic Eye Center, we believe that every patient should have the very best technology. We charge one fee for all patients and do not choose the laser based on cost or on your prescription. Our fee includes all of your pre-op and post-op care, as well as your post-op eye drops. We also offer financing options through Alphaeon Credit to make LASIK affordable for anyone. Financing can be discussed with your LASIK advisor at the time of your consultation.

Which lasers does Diagnostic Eye Center use?

Our doctors use the WaveLight® FS200 Femtosecond Laser to make the flap, and then use the WaveLight® Allegretto Wave® Eye-Q, Excimer Laser, to perform the treatment. Dr. Sanders and Dr. Salem are committed to providing the very best technology for their patients and take pride in having the most advanced lasers available.

How do I know if I’m a candidate for LASIK?

The first step to finding out if you are a suitable candidate for LASIK is to schedule your free consultation. At your consultation, several measurements will be taken of your eyes to determine if you qualify for LASIK or perhaps another refractive procedure. You will meet with one of our doctors to discuss your options and expected results. If you elect to proceed, all pre-op testing can usually be performed the same day.

Do I need to stop wearing my contact lenses before I have LASIK surgery?

Contact lenses change the shape of your eyes and can interfere with crucial measurements we must take. You do not need to stop wearing contacts for your consultation, but you do need to be out of your contact lenses prior to your procedure. We recommend discontinuation of one week for soft lenses and one month for rigid gas permeable or hard lenses. Please bring your contact lens information to your consultation, as this is important information for our doctors.

What can I expect on the day of LASIK surgery?

On the day of your procedure, you will arrive at the main office where you had your consultation, and several final measurements will be made to ensure accuracy. Most patients are given a mild sedative then rest in our comfortable relaxation room. You will be brought into the surgery suite once it is time for your procedure where our team will prep your eyes with anesthetic drops. Your surgeon will talk you through the entire procedure, which takes less than ten minutes. Before you leave, your LASIK advisor will go over all post-operative instructions with you and ensure all of your questions are answered. You can expect to be at the office for a total of about one to two hours.

How soon will my vision recover after LASIK?

You can expect your vision to be blurred the day of the procedure. Most patients see about as well as they did with glasses or contacts the very next day and feel comfortable enough to drive to their 1-day post-op appointment. Most patients also return to work within one day.

What are the complications or side effects of LASIK surgery?

Although LASIK is very safe and effective, there are potential side effects and complications. Most patients experience some dryness immediately following surgery, which usually resolves after a few months. If you have dry eye syndrome, this can be treated prior to proceeding with LASIK to minimize this side effect. Glare and halos are much less frequent with the newer generation of lasers and are rarely a problem. Loss of vision from LASIK is extremely uncommon, particularly if patients are screened properly. At Diagnostic Eye Center, we perform thorough testing to ensure that you are a suitable candidate. Further information on the risks and side effects of LASIK can be found at

What are my other options for surgical vision correction?

At the time of your consultation, your doctor will discuss which options are available and will recommend which procedure will give you the best result. Other available options include Advanced Surface Ablation (ASA), Implantable Collamer Lens (ICL), and Refractive Lens Exchange (RLE). For most patients, LASIK remains the best option.

What are my options if I wear bifocals?

LASIK can only correct distance vision or near vision, but not both at the same time. For patients under the age of 40-45, this is not an issue, as the focusing mechanism in their eyes still allows them to see at near. For patients who wear bifocals now, there are three options. One is to correct only the distance vision and then wear drugstore readers as needed for close vision. Another option is called monovision, in which one eye is corrected for distance and the other is corrected for near. Premium intraocular lenses now provide another alternative through a procedure called Refractive Lens Exchange. These lenses are implanted in the eye and can correct distance and near vision simultaneously. Your doctor will discuss your options with you at your consultation.

Why should I choose Diagnostic Eye Center for my LASIK surgery?

Other Refractive Procedures

While LASIK is the most popular refractive procedure performed today, some patients are better candidates for other vision correction procedures, such as Advanced Surface Ablation, Phakic IOL, or Refractive Lens Exchange. During your consultation, you will meet with one of our doctors to discuss your individual needs, as well as which procedure is best suited for your eyes.

Advanced Surface Ablation

Advanced Surface Ablation (ASA), also known as LASEK, is laser vision correction without making a flap. It represents a surgical advancement over photorefractive keratectomy (PRK), which was the original laser vision correction procedure first approved by the FDA in 1995. ASA combines certain elements of both PRK and the more popular LASIK procedure and may offer some advantages over LASIK for certain patients. With ASA, instead of completely removing the epithelium, as is done with PRK, the flap of surface epithelium is loosened with a diluted alcohol solution and moved to the side. The surface under the epithelium is treated with the Excimer Laser, and the epithelial flap is returned to its original position, similar to LASIK. A protective soft contact lens is then placed over the cornea to make the eye more comfortable as it heals. Final visual results are similar when comparing LASIK and ASA. There are a few conditions where ASA is preferred, such as thin corneas, dry eye syndrome, and epithelial basement membrane dystrophy. There is a theoretical advantage in that there can be no flap complications such as flap displacement; however, flap complications with LASIK are very uncommon. The disadvantages are that most patients experience some post-operative pain and longer visual recovery time. Your doctor can discuss Advanced Surface Ablation with you during your consultation.

Phakic IOL

A Phakic Intraocular Lens (IOL), also referred to as an Implantable Collamer Lens (ICL), is a lens that is permanently implanted in the eye behind the cornea. It is called a Phakic IOL because the eye still has its natural lens. The implanted lens contains a refractive power which compensates for the eye’s nearsightedness and can correct refractive errors outside the range of LASIK, up to -20 diopters. A Phakic IOL may be the procedure of choice for patients with dry eyes or thin corneas that do not qualify for laser vision correction. The first step is to create two small openings near the edge of the colored part of the eye (the iris) to allow the intraocular fluid to circulate around the lens. This is done one to two weeks before the lens implantation. The actual phakic IOL procedure is a short 15-minute outpatient operation. A small opening is created in the cornea, through which the folded lens is inserted. Once the lens has fully unfolded, the four corners of the lens are placed behind the iris. This makes the lens invisible to both you and others.

Refractive Lens Exchange

Refractive Lens Exchange (RLE) corrects refractive errors using an intraocular lens implant. RLE may be the procedure of choice for patients with a large amount of hyperopia (farsightedness) or for patients with early cataracts or a need to lower their intraocular pressure. Millions of patients have received intraocular lens implants when undergoing cataract surgery, using the same highly successful surgical techniques used in RLE. The primary difference between cataract surgery and RLE is that cataract surgery is performed to remove a patient’s cloudy lens, and RLE is performed to reduce a patient’s dependence on glasses or contact lenses. Performed as an outpatient procedure, the eye’s natural lens is replaced with an intraocular lens implant (or IOL). You will remain comfortable, as the eye is completely anesthetized. Very tiny incisions are made on the front part of the eye using a femtosecond laser. The natural lens is then removed, and an intraocular lens is placed inside the eye. Most patients report improvement in their vision almost immediately. Strenuous activity should be avoided for one week, but you can return to a desk job the day after surgery. One eye is done at a time, and the second eye is usually done one or two weeks later.
