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.
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.
In the Blade-Less technique, there are no blades working on the eye. The whole procedure is done by the use of one or combination of two lasers; Femto Laser and Excimer Laser. The precision of Femto Laser is to the levels of 5 microns.
In Blade procedures, a special blade called microkeratome is used to make the corneal flap and then Excimer Laser is used to correct the spectacle power. Modern microkeratomes are able to create flap almost similar to the ones created by Femto Lasers.
“Very comfortable and clean, friendly staff. Thank you. All the staff and ‘trainees’ were excellent, thank you very much for making a potentially stressful time very bearable.”
“Relaxed atmosphere and friendliness of all staff and trainees. They were all brilliant.”
“Staff made me feel confident and relaxed about a procedure I was very apprehensive and nervous about. The outcome has been beyond my expectations. Thank you”
