In the hyperopic eye the cornea and lens are too flat and focus the image to a point behind the retina; the image is then seen as a blur. The muscles controlling the lens can overcome some degree of hyperopia but weaken with age. This is why many hyperopes begin to require distance and near glasses after the age of 30.
After laser correction with LASIK the cornea is slightly more curved; the image is then clearly focused on the retina. The result is that the hyperopic patient can see clearly for distance after laser treatment.
✓ 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.
✓”Pseudophakic" Intra-Ocular Lens
“Clear lens extraction" is performed when excimer laser surgery is not possible. The intra-ocular lens replaces the natural lens of the eye (pseudophakic implant), in a procedure similar to cataract extraction.
