What Is LASIK Eye Surgery?

LASIK (Laser-Assisted-In-Situ Keratomileusis) is a highly effective outpatient procedure used to correct most ranges of nearsightedness, farsightedness and astigmatism. The benefits can be tremendous for all people, especially active and social people or professions where glasses are a hindrance.

iLASIK Is Next-Generation LASIK

iLASIK is the fusion of the industry’s most stellar vision correction technologies into one premium procedure. For most people the result is dramatically improved vision. iLASIK also offers a shorter time from procedure to healing.

How LASIK Works

LASIK surgery corrects or greatly improves three common refractive errors in vision: myopia (nearsightedness), hyperopia (farsightedness) and astigmatism (irregular curvature of the cornea). In each of these conditions, light entering the eye through the cornea and lens fails to focus properly on the back of the eye (the retina). The result is blurred vision. iLASIK creates a detailed map of the imperfections in your eye, then reshapes the cornea to restore good eyesight without the need for glasses or contact lenses.

Am I a Candidate for LASIK Surgery?

  • You need to be at least 18 years old to ensure that the eye has developed fully.
  • Your vision must have been stable for at least one year before eye surgery, with no eye infection or injury during that time.
  • Women who are pregnant or nursing should wait to have surgery.
  • If your pupils dilate beyond seven millimeters, or if there is scarring on your cornea, LASIK will not work well for you. Coastal Eye Associates can provide alternatives.

The First Step

The first step in the LASIK procedure is to perform a series of tests to determine the individual characteristics of your vision, including the use of our CustomVue iDesign technology. The iDesign system creates a 3-D map of the unique imperfections of your eyes. The CustomVue WavePrint Map provides a precise, more detailed analysis of the way your entire optical system operates. With the CustomVue WavePrint Map, Dr. Yazdanie can create a detailed understanding of your vision correction needs for the development of your personalized laser vision plan. The CustomVue iDesign System acts as the guidance system for our VISX Star S4 Excimer Laser. This allows Dr. Yazdanie to provide you with laser vision corrections based on measurements 25 times more accurate than are possible with any system used to produce glasses or contact lenses. The final result is a treatment as unique as your DNA or your fingerprint.

Day of Surgery

Our iLASIK procedure is quick, safe, and generally described as pain-free. The eye surgery itself typically takes no more than 20 minutes. On the day of the procedure, your unique correction information is transferred directly from the CustomVue iDesign to the VISX Star S4 Excimer Laser. You will receive a mild oral sedative to help you relax, but you will remain alert and comfortable during the procedure. Before the procedure, we will administer anesthetic eye drops to ensure your comfort throughout. You will lie on a table beneath the laser equipment during the procedure. Each eye will be treated individually while being held open by a speculum.

iLASIK Surgery Is A Two-Step Process

  • Step 1 – Dr. Yazdanie creates a tiny-hinged flap on the surface of the cornea. LASIK surgery utilizes the IntraLase Laser which is a new state of the art femtosecond laser treatment that creates the LASIK corneal flap by using a blade-free computerized laser technique. With the IntraLase Method, tiny pulses of laser light pass harmlessly through the outer surface of the cornea, forming a uniform layer of microscopic bubbles just under the surface. Dr. Yazdanie determines the exact dimensions of the bubble layer and this is all computer controlled for maximum precision. He is then able to gently separate the layers, creating the flap.
  • Step 2 – Dr. Yazdanie lifts the corneal flap, the 3-D Auto-Tracker is engaged, and Iris Registration is confirmed. After this confirmation, the actual laser vision correction is performed. The cornea is reshaped in a way that is uniquely safe and predictable, employing the Advanced CustomVue iDesign method on the VISX Star S4 Excimer Laser. When this reshaping is complete after several seconds of treatment, the flap is gently replaced in its original position, where it literally “locks” back into place due to its precise shape, and your eye heals very quickly over the next several hours.

After Surgery

Once the LASIK procedure is completed, you are advised to go home and rest, keeping your eyes closed as much as possible for the remainder of the day. Antibiotic, anti-inflammatory and lubricating eye drops will be prescribed. Activities that strain the eyes – reading and computer – should be avoided for 24-48 hours. You may watch TV or movies after six hours. You will have a follow-up appointment the day after surgery. While each person’s comfort level may differ, you may experience mild side effects that include tearing, sensitivity to bright lights and a feeling of “scratchiness”. Your vision may be somewhat hazy at first, but over time, these side effects should disappear. You can enjoy your normal activities with dramatically improved vision!

Frequently Asked Questions About LASIK

The entire iLASIK procedure takes approximately 10 minutes per eye including preparing your eyes for treatment. The actual laser time is about 20 seconds to create the flap, and then anywhere from 20 seconds to a minute to reshape the cornea. The more refractive error you have the longer the laser time.

Most people are able to return to work the day after LASIK surgery, but many people who do extensive near-sighted tasks or computer work are asked to take an extra day off. If you work in a location that has a lot of dirt or debris, we recommend you take an extra day or two to recover.

During the actual LASIK procedure there is no pain because anesthetic drops are placed in the eye. A slight pressure sensation may be felt during the creation of the flap, but absolutely no pain is involved in the procedure. Many of our patients tell us that after the procedure is done and the anesthetic drops have worn off, it feels like a bad day with contact lenses as if your eyes are dry, scratchy or irritated. We advise our patients to use Ibuprofen or Extra Strength Tylenol, and to call us if the discomfort worsens after a few hours, as this is very unusual.

You can resume most normal activities such as driving, working, and mild exercise the day after surgery. We advise patients with high risk leisure activities to wait one week and wear eye protection (kickboxing, karate, basketball, swimming, or other contact sports). Women are advised not to wear eyeliner or mascara for one week post operatively. This is because unlike eye shadow, mascara and eyeliner need to be rubbed off. We also strongly advise our patients to wear protective eyewear when doing potentially hazardous activities.

Our outcomes are better than ever with over a 90% 20/20 or better rate. The day of surgery your vision will be blurry, however, the quality of vision will improve over the first 24 hours with most patients seeing 20/20 the day after surgery. It can continue to improve up to two weeks following your procedure.

Yes, iLASIK is one of the few eye surgeries where it is recommended to have both eyes treated at the same time. Our patients appear to heal faster and easier when both eyes are focused the same way. Most of our patients prefer to have both eyes treated at the same time as it also is easier on their busy lifestyles and causes them less downtime. An exception to this rule may be for patients with extreme prescriptions who have PRK. This procedure while as great as LASIK, tends to heal slower and many people chose to keep one eye working while one eye heals.

With the new technology of Intralase our patients have a safer procedure with less risk of mechanical problems caused by the Microkeratome Blade surgery. Our new Intra-LASIK procedure is all laser and is Blade Free. Complications with this surgery are rare, but as with any surgical procedure there are risks and benefits. Please contact our office to discuss your concerns. We provide a consent form and the VISX FDA booklet available for you to review so you may make an educated decision for surgery.

During LASIK surgery, the cornea is reshaped to correct vision problems. This reshaping is permanent. You may still experience the normal vision changes that come with age which results in the need for reading glasses. This is known as presbyopia and is the result of the eye’s lens losing its flexibility due to age. It’s not caused by the cornea which was corrected during LASIK.

We will give you numbing eye drops which will take away the urge to blink. Then an instrument called a lid spectrum is used to gently hold back your upper and lower eyelids. Between the numbness from the eye drops and the lid spectrum you will be in a good spot because we only need a few seconds.

The short answer is, NO. Most of our patients describe a slight pressure sensation during LASIK. You will also have numbing eye drops and and you may be given an oral relaxation medication beforehand. There are NO shots or injections.
