In the myopic eye the image does not reach the back part of the eye (the retina). In the myopic eye the cornea and lens are too curved and focus the image to a point in front of the retina, the image is then seen as a blur. Only by moving up close to the image will it be shifted on to the retina and seen clearly. Myopic people can see up close, but need glasses or contact lenses to see far away.
LASIK involves slightly flattening the cornea which is the curved rounded front surface of the eye; the image is then clearly focused on the retina. Modern surgical techniques can correct or significantly reduce almost all cases of myopia.
✓ Customized Lasik with the Schwind Amaris laser
The Schwind Amaris is a latest generation laser approved by Health Canada in 2012. Clinique Laservue was the first in North America to acquire this technology. This laser has the most sophisticated eye tracker on the market, which follows your eye in "6-Dimensions" (see video below), thus assuring centration of the treatment even in the presence of microscopic eye movements during treatment. It is ultra-fast (500 pulses per second) and ultra-precise, and the vast majority of our patients achieve 20/20 vision the very next day.
✓ - PRK (photo-refractive keratectomy)
PRK is an older technique than Lasik. Betwen 1992 and 1995, the Laservue surgeons performed over 4000 PRKs. The main disadvantage is that the outer skin of the eye must be removed before applying the excimer laser. The healing is thus much slower. We will still perform PRK in patients with corneas too thin for Lasik.
✓ "Phakic" Intra-Ocular Lens for high myopia
"Refractive" intra-ocular lens implantation is performed when excimer laser surgery is not possible. The intra-ocular lens is placed near the natural lens of the eye (phakic implant), or replaces it. .
