INTRALASE FAQS

Why Intralase?

The advent of the IntraLase laser has helped make LASIK laser vision correction safer and more precise than ever before. The procedure is quiet, comfortable and allows patients who were not considered candidates for LASIK, even some with thin corneas, to achieve freedom from glasses and contact lenses.

What Is Intralase?

LASIK laser vision correction is essentially a two-step procedure. During the first step, a flap is created on the surface of the cornea. After the corneal flap is gently lifted, an excimer laser is used to reshape the cornea in the second step.

In traditional LASIK, the corneal flap is created with a mechanical device called a microkeratome. The microkeratome has a very sharp, precise blade that gently cuts a layer of the cornea at a predetermined depth. Conversely, the IntraLase is a femtosecond laser that creates the flap by generating microscopic bubbles below the corneal surface – without ever using a blade to cut. This is the arrival of bladeless, all-laser LASIK.

Unlike the mechanical microkeratome, the IntraLase allows us to more precisely program the dimensions of your corneal flap based on the shape of your eye and the specific refractive correction desired. Tiny, rapid pulses of laser light are focused at a precise depth and diameter determined by the surgeon. The laser light passes harmlessly through the cornea and creates rows of bubbles just beneath the surface of the cornea as it moves uniformly back and forth across the eye. The IntraLase laser then stacks bubbles around the diameter of the cornea to establish edges of the flap. The entire process takes approximately 20 seconds.

WAVEFRONT GUIDED CUSTOM ABLATION FAQS

What is Wavefront Guided Custom Ablation?

Custom ablations are customized surgical vaporizations using a laser in order to resculpt the cornea for laser vision correction. Custom ablations use wavefront LASIK surgery technology to achieve their customization. Wavefront technology is a technology that uses customized mapping of the optic irregularities of a patient’s cornea that can be used to guide laser vision correction surgery. Wavefront technology works by determining how light is distorted as it moves through the eye and then is reflected back. The types of distortions the wavefront obtains as it goes through the eye provide significant information concerning an individual’s vision errors and how to correct them. In an eye with perfect vision, the wavefront is perfectly flat; whereas the wavefront of an imperfect eye is uneven. An optical map of the eye is produced showing the individual’s flaws. Vision errors are automatically recognized as an effect of the way light waves pass through the eye. Any laser vision correction procedure that uses wavefront/custom laser vision correction or custom LASIK (Laser-Assisted in Situ Keratomileusis) is using custom ablation technology.

Why is it Significant?

Custom ablations treat traditional eye problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (irregularly shaped eye which causes blurred or double vision) as well as additional vision problems orCustom ablations treat traditional eye problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (irregularly shaped eye which causes blurred or double vision) as well as additional vision problems or optical irregularities which are known as higher-order aberrations. Custom ablations particularly benefit those patients with greater higher-order aberrations as well as patients who have larger-than-average pupil sizes prior to their surgery.
Custom ablations are revolutionary inventions because they not only improve how much you can see but also how well you can see in terms of fine detail and contrast sensitivity. Because of this, there is less of a risk of postoperative complications from the LASIK procedure like glare, halos, or night vision difficulties. Custom ablations using wavefront technology also offer patients a higher possibility of attaining 20/20 vision or better.


Another exciting possibility with custom ablations is that patients who may have developed unwanted side effects such as glare or halos when using night vision from previous LASIK surgery may be able to get their eyes retreated using custom ablations to correct these unwanted side effects. The wavefront technology can create a custom map of these visual distortions, and custom ablations can be used to correct them. optical irregularities which are known as higher-order aberrations.

ALCON CONTOURA VISION FAQS

What is Alcon Contoura Vision?

Alcon Contoura vision is another type of custom guided LASIK and PRK. The surface of your eye is as unique as your fingerprint, and CONTOURA®Vision is revolutionary to LASIK, working with WaveLight® LASIK technology to tailor your laser vision correction procedure to your unique eye, redefining the quality of what you see. You can think of CONTOURA® Vision as “personalized LASIK.” Sometimes known as topography-guided LASIK, CONTOURA® Vision personalizes your LASIK procedure by creating a precise map of your eye that includes up to 22,000 unique elevation points.

Why is it significant?

With CONTOURA® Vision, life after a LASIK procedure means excellent vision for a large number of patients. Of eyes treated with CONTOURA® Vision, 92.6% achieved 20/20 vision or better, in an analysis of FDA study results on LASIK.3 And many patients saw even greater benefits from topography-guided LASIK: nearly two-thirds of eyes achieved at least 20/16 vision, and 15.7% of eyes achieved 20/10 vision or better Essentially, Contoura provides better post-operative outcomes, with fewer side effects such as glare and halos. 30% of patients found that the quality of their vision was actually better after Contoura.  CONTOURA® Vision, which has been used safely and effectively outside the United States for more than 10 years, is a unique topography-guided LASIK procedure because of the way it maps the eye to guide treatment. It uses a topography instrument called the Vario Topolyzer to measure every submicroscopic peak and valley on the front of the eye, the cornea, to a hyper-precise degree. 

What's the difference between Wavefront- and Topography-Guided LASIK?

While wavefront-guided LASIK can produce good results by measuring somewhere around 200 points of curvature on the cornea, Contoura Vision measures 22,000 points. That information allows a computer to create an individualized treatment profile, which is then programmed into a state-of-the-art laser that automatically applies the treatment to the cornea. The laser smooths the shape of the cornea so all of the light rays passing through it reach the retina at the back of the eye uniformly, producing clear, crisp vision. Contoura Vision is truly individualized. The topography measurements are so exact that it would be impossible for any two treatments to be the same. Another difference between wavefront-guided and topography-guided LASIK is that wavefront measurements include all parts of the eye along the visual pathway, and topography measurements include only the cornea. This is important because the cornea is the location of most of the imperfections that can make vision less than ideal. While the lens of the eye can contribute to poor vision as well, it changes over time, which could work against the changes made to the cornea by LASIK.

How is Contoura Vision similar to other types of laser?

All LASIK treatments are applied underneath a flap that is created at the top layer of the cornea. The femtosecond intraslase laser creates the LASIK flap to precise dimensions so it conforms to your eye’s anatomy, is less disruptive to the delicate corneal tissue, and fits securely back in place after the treatment. Also at Manhattan Eye, the same German-engineered laser, the WavelightAllegretto Wave Eye-Q laser, is used to apply the planned treatment to the cornea in all types of LASIK. In addition to applying an accurate treatment, this laser places its pulses in a way that preserves the natural curvature of the cornea, which is important for preventing unwanted side effects such as glare and poor night vision. A 500Hz laser tracks even the slightest of eye movements during the procedure to ensure the exact intended location of the treatment is maintained.
