Your Eyes are Priceless...Examine Your Choices Carefully: The Herzig Eye Institute Supports FDA Inquiry Into LASIK

And Helps Patients Understand Options with The Patient Guide to Custom Vision Correction

TORONTO, ONTARIO--(Marketwire - May 9, 2008) - The Herzig Eye Institute applauds the recent FDA (US Food and Drug Administration) inquiry into LASIK complications and has developed The Patient Guide to Custom Vision Correction to help patients understand the various treatment options available. Visit http://www.herzig-eye.com for more information or go to http://www.herzig-eye.com/html/inquiry-response.html for the downloadable PDF.

The FDA is not questioning LASIK as a procedure but is telling patients that they need to be aware of the risks and benefits and they should select a surgeon that will use the most advanced equipment. If cost is an issue, potential candidates should probably not proceed. Visit http://www.fda.gov/cdrh/lasik/risks.htm for more details.

Selecting a reputable centre that has surgeons who are at the top of their field is the most important step to take to decrease any risks associated with LASIK. An experienced, reputable surgeon will make sure you are properly screened and will let you know up front if you are a good candidate for LASIK eye surgery or if there is another option that might be more suitable. Take great care to choose a facility and surgeon that uses the most advanced technology available and provides other advanced vision correction options.

Since 1998, LASIK (laser-assisted in situ keratomilieusis) has become the most prevalent laser vision correction procedure in the world. It has proven to be an extremely safe and effective method of correcting myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.

Discount laser eye centres that rely on older technology have created some of the recent concerns about the safety of LASIK. Not using the best technology available means less than optimal results, and higher risk. Beware of the "LASIK only" approach.

"Although the vast majority of patients who undergo LASIK will see 20/20 or even better following laser eye surgery, there are people who are not candidates for LASIK," states Dr. Sheldon Herzig, Medical Director, Herzig Eye Institute. "That is why at Herzig Eye Institute, great care is taken during the surgical consultation to determine if patients are candidates for laser vision correction and to determine the best solution for each individual patient. LASIK, PRK, Refractive Lens Exchange (RLE), and the Implantable Contact Lens are recommended by the Herzig Eye Institute."

Good laser vision correction (LVC) candidates are at least 18 years old, in good health, have had a stable vision prescription for one year, have no existing eye diseases and have healthy corneas. A complete consultation is required to determine your candidacy for LVC or other vision correction procedures.

"It is important to ask questions before committing to your procedure," adds Dr. Herzig. "If LASIK is not your optimal solution, find out if any alternatives are available. Your candidacy and which procedure is right for you will be determined during your initial consultation. Patients considering LVC should be very careful in choosing where he or she has his or her procedure done. Your eyes are priceless, and the least important consideration should be the cost of the procedure."

The Patient Guide to Custom Vision Correction offers tips on what to look for in a surgeon, discusses patient candidacy, examines the treatments options available, describes the procedures and provides valuable information on post treatment management.

Custom Vision Correction at Herzig Eye Institute

For more than twelve years, surgeons at the Herzig Eye Institute have performed over 150,000 refractive and advanced cataract procedures using the most advanced state-of-the-art technology to provide each patient with a custom vision correction called High Definition Vision® to meet their unique needs.

A leader in cataract and refractive eye surgery, Dr. Sheldon Herzig leads a team of top-tier surgeons at the Herzig Eye Institute who customize treatments and apply the right technology to the right patient. The Herzig Eye Institute provides custom vision correction using the most advanced technology available that combines VISX® Wavefront guided PRK or LASIK with IntraLase® (iLASIK™), as well as offering other proven intraocular surgical procedures for patients who do not qualify for laser surgery, such as Refractive Lens Exchange (RLE), NearVision CK, or the Implantable Contact Lens (ICL).

The Herzig Eye Institute offers two types of custom laser vision correction treatments: iLASIK or PRK (Photorefractive Keratectomy), both of which provide excellent results for correcting vision and eliminating the need for glasses. The thickness of the cornea and the surgeon's interpretation of corneal topography and other measurements determine whether iLASIK or PRK are more appropriate.

For nearsighted people, surgeons use a custom LVC procedure to flatten the curve of the cornea; for farsighted people a steeper cornea is created, and for people with astigmatism their vision can be corrected by making their oval cornea into a more round shape.

A series of tests are performed to determine the individual characteristics of the patient's vision using the VISX Wavefront-Guided CustomVue™ system to accurately measure and correct the unique imperfections of each individual's vision by creating a 3-D map of the patient's eyes. Herzig Eye Institute surgeons are able to use this information to design a custom treatment for that enables patients to achieve a far better vision outcome than what they are currently experiencing with glasses or contacts. Studies done at several North American laser centres have shown excellent results in Wavefront's ability to improve night vision.

iLASIK combines Wavefront LASIK with IntraLase and involves two steps. The first being the creation of a corneal flap, and the second the reshaping of the cornea with a laser.

Traditionally, the corneal flap was created with a hand-held oscillating blade called a microkeratome. While this method has worked well over the years, the use of the IntraLase laser to make the flap has made the procedure more precise and safer.

The surgeon uses the precision of this computer-guided IntraLase laser in this 100% blade-free approach to establish the precise dimensions and thickness of the corneal flap, factors which are critical to a successful iLASIK outcome. Consistently accurate, IntraLase has allowed LASIK to become a viable option for patients who might not have previously been a candidate.

Once the surgeon creates a corneal flap, the tissue is folded back to prepare the eye for treatment. Corneal tissue is removed using an excimer laser that uses a cool ultraviolet light beam to painlessly reshape the cornea through a series of ultra precise pulses. The flap is then laid back in place, covering the area where the corneal tissue was removed and the eye heals quickly.

Custom LVC (PRK and LASIK) is the Herzig Eye Institute's most frequently used High Definition Vision® solution and offers improved safety and advanced precision with predictably better visual results for the patient than previous technologies. Clinical studies have shown that patients who have been treated with the IntraLase laser in combination with VISX Wavefront technology receive better vision than they had with glasses or contacts and 98% achieve 20/20 vision or better.

A wide range of myopia, hyperopia, and astigmatism can be corrected by the custom LVC procedure.

The custom PRK and iLASIK technology platform continues to pass every test. Recently, the National Aeronautics and Space Administration (NASA) approved LASIK for use on U.S. astronauts, and this out-of-this-world milestone comes on the heels of a similar approval for all branches of the U.S. military personnel, including most recently Air Force pilots.

Where traditional LVC is used to treat nearsightedness, farsightedness, and astigmatism, Monovision LVC is an effective procedure that can address the distance and near vision needs of eyes over 40. Monovision LVC adjusts one eye to see things close, while the other eye sees things at a distance. The patient's brain then integrates this information to improve vision. The US Food and Drug Administration has approved this method of treatment.

PRK uses the same excimer laser as iLASIK to shape the cornea. It differs, however, in being performed on the surface of the cornea, after removing or lifting the corneal epithelium, instead of a corneal flap, and is commonly referred to as "surface ablation." PRK is used in cases where: the cornea is too thin for iLASIK; there is a pre-existing problem on the cornea which can be eliminated with PRK and result in better vision than iLASIK, or if there is a structural abnormality in the cornea that makes iLASIK unsafe.

PRK provides the same visual result using the Advanced CustomVue technology, but with a slightly different and longer recovery period.

Other Vision Correction Options

A small number of people have refractive errors that are too large or eye conditions that are not appropriate for laser vision correction. In these situations, there are other treatments that are available at the Herzig Eye Institute.

Refractive Lens Exchange (Clear Lens Extraction)

The Refractive Lens Exchange is used for patients with very high levels of nearsightedness or farsightedness, and for people who have early lens opacities. In addition, people in their middle years may appreciate the dual advantage of a refractive lens exchange: not only will it correct nearsightedness or farsightedness, but it also prevents any future need for cataract surgery.

The Implantable Contact Lens (ICL)

The Implantable Contact Lens is used for patients who are at least 18 years of age, with high levels of myopia, hyperopia, or astigmatism that are too extreme for laser vision correction, and for whom laser vision correction on the cornea is not safe.

NearVision CK

Presbyopia is the loss of elasticity in the eye's lens, and it affects everyone over 40, whether they've had perfect vision all their life or have undergone laser eye surgery to achieve that state. It's the condition that diminishes near vision, leaving patients to fumble with reading glasses. NearVision CK uses radio frequency energy to reshape the cornea and bring near vision back into focus.

Advanced Refractive Cataract Surgery

The Herzig Eye Institute is dedicated to providing the most recent technological advancements for Advanced Refractive Cataract Surgery to increase a patient's potential of regaining their full range of vision, including reading vision, by utilizing presbyopic and multifocal intraocular lenses (IOLs) that simulate the youthful, natural lens. 85-90% of patients are completely glasses free following Advanced Refractive Cataract Surgery.
