What is LASIK Toronto?

So what is Lasik Laser Eye Surgery Toronto? The cornea is a part of the eye that helps focus light to create an image on the retina. It works almost like the lens of a camera focuses light to create an image on film. The light from the bending and focusing is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is blurred (blurred) or distorted. These gaps in the focusing power of the eye are called refractive errors. There are three main types of refractive errors: myopia, hyperopia and astigmatism. People with myopia or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. People with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects. Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common.

LASER EYE SURGERY TORONTO

Glasses or contact lenses are designed to replace the imperfection of the eye. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue with a special laser to change the cornea and change its focus on power.

Other types of refractive eye surgery laser Eye Surgery Toronto

Radial keratotomy laser eye surgery Toronto, or RK and PRK are refractive keratectomy or other refractive surgeries used to reshape the cornea. In RK, a sharp knife used for cutting the cornea, changing its shape. PRK was the first surgical procedure developed to reshape the cornea, by sculpting, using a laser. Later, LASIK was developed. The same type of laser used for LASIK and PRK. Often the exact same laser is used for both types of surgery. The main difference between the two surgeries is the way that the stroma, the middle layer of the cornea, is exposed before it is vaporized with the laser. In PRK, the top layer of the cornea called the epithelium, is scraped away to expose the stromal layer underneath. In LASIK, the flap is cut in the stromal layer and the flap is folded.

Another type of refractive surgery is thermokeratoplasty where heat is used to reshape the cornea. The heat source may be a laser, but that is another type of laser used for LASIK and PRK. Other devices refractive corneal ring segments that are inserted into the stroma of contact lenses and individuals that temporarily reshape the cornea (orthokeratology)
