iLASIK at Lusk Eye Specialists

Setting New Standards in Vision Correction

shreveport lasikDuring the past 25 years, LASIK laser vision correction has become the safest and most popular method of vision correction in the world. Since 1990, LASIK has helped millions of just like you look beyond their glasses and contact lenses.

LASIK is an acronym that stands for Laser In-Situ Keratomileusis. It has two steps. Step one is the creation of a thin corneal flap that serves as a protective layer and improves healing time. The second step involves gently lifting the corneal flap and using an Excimer laser to reshape the inner layers of the cornea using non-thermal (cool) beams of light.

shreveport prkA LASIK procedure takes only a few minutes to complete, but patients may be in the laser suite for 115-20 minutes. Patients remain awake and comfortable during LASIK and report very little discomfort. Here are Lusk Eye Specialists, we perform LASIK in the comfort and safety of a specially designed laser suite that is located in our outpatient surgery center next door to Lusk Eye Specialists. To help reduce possible risks and complications, factors such as humidity, temperature and overall air quality are closely monitored and maintained.

shreveport laser vision correctionWe are proud to help take LASIK to the next level with CustomVue™, a Wavefront Custom laser procedure approved by the FDA. During the CustomVue™ procedure, diagnostic information gathered during the WaveFront scanning process is fed directly into our VISX Star S4 eye-tracking laser.Just like your fingerprint and DNA, the information fed into the laser is unique to your eyes only. Each of your eyes will receive its own custom laser procedure, with no two custom procedures in the world being identical.

Lusk Eye Specialists is also now proud to offer patients the added safety and precision of the 5th Generation iFS Advanced Femtosecond Laser. The iFS Laser is allows us to perform a method of LASIK we call iLASIK, a 100% blade-free procedure. This is the same type of LASIK approved by NASA for our astronauts and by the U.S. military for Top Gun fighter pilots and members of the Special Forces.

To help maximize safety during your iLASIK procedure, Lusk Eye Specialists use the VisX Star S4 eye-tracking laser with Iris Registration. This allows the laser to shift with the eye as it tracks the eye during your procedure. Iris Registration is a non-contact method for aligning the advanced CustomVue procedure. Lusk Eye Specialists is now able to take photos of unique areas on individual’s iris so that the laser correctly centers and aligns the treatment on the iris. With Iris Registration, there is no possibility of treating a wrong eye or the wrong patient.

A level of visual clarity and sharpness – beyond the capabilities of glasses or contacts – is now possible with our custom wavefront-guided laser vision correction on the VISX Star S4 Excimer Laser. This allows Lusk Eye Specialists to expand laser vision correction treatment to a wider group of patients than is currently available. So if you’ve been told you are not a candidate for LASIK, please call us for a free consultation and a second opinion.

One of the most popular ways to correct vision is with a procedure called LASIK (laser in-situ keratomileusis), which uses a laser to change the curvature of the cornea (outer window of the eye). LASIK has quickly become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. In fact, most Shreveport LASIK patients notice a significant improvement in their vision soon after surgery. LASIK removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism.

To treat nearsightedness, the steep cornea is made flatter by removing tissue from the center of the cornea. This moves the point of focus from in front of the retina to directly on the retina.

Treating Nearsightedness
To treat farsightedness, the flat cornea is made steeper by removing tissue outside of the central optical zone of the cornea. This moves the point of focus from behind the retina to directly on the retina.

Treating Farsightedness
To treat astigmatism, the cornea is made more spherical — like a basketball instead of a football. This eliminates multiple focusing points within the eye and creates one point of focus on the retina. Astigmatism can be treated at the same time as nearsightedness and farsightedness.

Treating Astigmatism

LASIK is for those who:

  • want to reduce or eliminate thir dependence on glasses or contacts
  • are at least 21 years of age
  • have had a stable eye prescription for at least one year
  • have no health issues affecting their eyes
  • have no signs of glaucoma or cataracts

What to expect on surgery day:

You will arrive at the Lusk Eye Specialists about an hour prior to your procedure. Once you have been checked in you may be offered a sedative to help you relax. You will then be prepared for surgery. The area around your eyes will be cleaned and a sterile drape may be applied around your eye. Anesthetic eye drops will be used to numb your eyes; no injections or needles will be used. When your eye is completely numb, an eyelid holder will be placed between your eyelids to keep you from blinking during the procedure.

Following your procedure, your eye(s) will be examined with a slit lamp microscope. Then you will be given additional eye drops, and your eyes may be shielded for protection. Your vision will probably be a little blurry at first, so someone will need to drive you home. You should relax for the rest of the day. You may experience some discomfort for 12 to 24 hours, but this is usually alleviated with an over-the-counter pain reliever. Some people experience sensitivity to light, and watering or swelling of their eyes for a few days following their procedure.

You will be asked to come back the next day for another examination of your eye(s). Most people can actually see well enough to drive the next day but it’s best not to drive until you have been examined. You should be able to resume your normal activities the day after surgery.

Vision can fluctuate for up to six months, but most people can see well enough to pass a driver’s license vision exam following their procedure.

Shreveport PRK Vision Correction

PRK Vision Correction – What is Nearsightedness?

Dr. Lusk can also provide Shreveport PRK vision correction as an alternative to traditional LASIK. In the normal eye, light bends through the cornea and lens to focus on the retina. With nearsightedness the eye is longer (or cornea is steeper) causing light to focus in front of the retina. The image is therefore out of focus on the retina and vision is blurred.

The Treatment

Epithelium Removal

1. The corneal epithelium is removed in the treatment area.
Excimer Laser Reshaping Cornea

2. Excimer laser is applied reshape (ablate) the cornea.
Epithelium Growing over Treated Area

3. The corneal epithelium grows over the treated area.
Cornea Focusing on Retina

4. The “flatter” cornea bends light to become focused on the retina.

The Result:

Before PRK treatment, light is out of focus on the retina. After PRK treatment, the “flatter” cornea causes light to bend in such a way as to become focused on the retina. Vision is clear.

Risks & Contraindication

The FS and iFS Laser systems are ophthalmic surgical lasers indicated for use in patients undergoing surgery or treatment requiring the initial lamellar resection of the cornea. Contraindications may include corneal edema, glaucoma, and keratoconus. Risks and complications may include corneal pain, flap tearing, and epithelial ingrowth. Consult with your eye care professional for a complete listing of contraindications and risks. US Federal law restricts this device to sale, distribution, and use by or on the order of a physician or other licensed eye care practitioner.

Most patients are very pleased with the results of their refractive surgery. However, like any other medical procedure, there are risks involved. That’s why it is important for you to understand the limitations and possible complications of refractive surgery. Before undergoing a refractive procedure, you should carefully weigh the risks and benefits based on your own personal value system, and try to avoid being influenced by friends that have had the procedure or doctors encouraging you to do so.

  • Some patients lose vision. Some patients lose lines of vision on the vision chart that cannot be corrected with glasses, contact lenses, or surgery as a result of treatment.
  • Some patients develop debilitating visual symptoms. Some patients develop glare, halos, and/or double vision that can seriously affect nighttime vision. Even with good vision on the vision chart, some patients do not see as well in situations of low contrast, such as at night or in fog, after treatment as compared to before treatment.
  • You may be under treated or over treated. Only a certain percent of patients achieve 20/20 vision without glasses or contacts. You may require additional treatment, but additional treatment may not be possible. You may still need glasses or contact lenses after surgery. This may be true even if you only required a very weak prescription before surgery. If you used reading glasses before surgery, you may still need reading glasses after surgery.
  • Some patients may develop severe dry eye syndrome. As a result of surgery, your eye may not be able to produce enough tears to keep the eye moist and comfortable. Dry eye not only causes discomfort, but can reduce visual quality due to intermittent blurring and other visual symptoms. This condition may be permanent. Intensive drop therapy and use of plugs or other procedures may be required.
  • Results are generally not as good in patients with very large refractive errors of any type. You should discuss your expectations with your doctor and realize that you may still require glasses or contacts after the surgery.
  • For some farsighted patients, results may diminish with age. If you are farsighted, the level of improved vision you experience after surgery may decrease with age. This can occur if your manifest refraction (a vision exam with lenses before dilating drops) is very different from your cycloplegic refraction (a vision exam with lenses after dilating drops).

Long-term data are not available. LASIK is a relatively new technology. The first laser was approved for LASIK eye surgery in 1998. Therefore, the long-term safety and effectiveness of LASIK surgery is not known.

FDA RISKS:

As with any surgical procedure there are risks associated with CustomVue TM treatments. It is important to discuss these risks with your doctor before you make the decision to have the surgery. If the results of the surgery are not satisfactory, you may need to have additional laser treatment in the same eye. Your doctor may perform CustomVue LASIK for both eyes. However, sometimes it is better to have this procedure done on only one eye. Talk with your doctor about whether it would be better to treat one or both of your eyes.

Some risks are related to the creation of the corneal flap. Corneal flap complications include but are not limited to: cutting an incomplete, irregular flap or free flap; misalignment of the flap; and perforation of the cornea. Corneal flap complications range in severity from those that simply require the treatment to be postponed for several months, to those which create corneal irregularities resulting in permanently blurred vision.

You may need reading glasses after laser surgery even if you did not wear them before. Your vision may not be perfect, and you may need to wear glasses or contact lenses for some activities even after laser vision correction.
CONTRAINDICATIONS:

If you have any of the following situations or conditions you should not have LASIK because the risk is greater than the benefit:

  • You are pregnant or nursing, because these conditions may cause temporary and unpredictable changes in your cornea and a LASIK treatment may improperly change the shape of your cornea.
  • You have collagen vascular disease (e.g., rheumatoid arthritis), autoimmune disease (e.g., lupus), or immunodeficiency disease (e.g., AIDS), because these conditions affect the body’s ability to heal.
  • You show signs of keratoconus or any other condition that causes a thinning of your cornea. This condition can lead to serious corneal problems during and after LASIK surgery. It may result in need for additional surgery and may result in poor vision after LASIK.
  • You are taking medications with ocular side effects, e.g., isotretinoin (Accutane®*) for acne treatment or amiodarone hydrochloride (Cordarone®t)for normalizing heart rhythm, because they may affect the accuracy of the LASIK treatment or the way your cornea heals after LASIK. This may result in poor vision after LASIK.
  • Your corneas are thin. If your corneas are too thin to allow your doctor to cut a proper flap in the LASIK procedure, you can’t have LASIK because it is necessary to have a flap.
