LASIK is a procedure that corrects nearsightedness, farsightedness and astigmatism, and can reduce or eliminate the need for reading glasses or contact lenses afterwards. It is the most common type of vision correction surgery and works by reshaping your cornea under a thin flap to focus light entering your eye to a single point, making your vision clearer and sharper. Vision is usually restored within 24 hours with minimal discomfort.
PRK is a procedure similar to LASIK, with reshaping of your cornea performed on the corneal surface, rather than under a flap. PRK is usually done when you are not a candidate for LASIK, as healing and vision improvement takes place more slowly, usually over weeks, rather than hours (compared to LASIK).
Clear Lens Extraction is a procedure that involves exchanging your out of focus natural lens for an artificial one that restores the proper focus for clear vision. As the lens ages and becomes harder and loses its focusing ability, CLE becomes the preferred choice for many individuals over 45 years of age who want visual freedom from glasses or contact lenses.
A cataract is simply a cloudy natural lens. When a cataract clouds your vision and interferes with your normal activities, cataract surgery may be necessary. This surgery involves exchanging your cataract with an artificial lens that is clear. This restores crisp vision while the new artificial lens implant will remain clear for life.
After the age of 45, everyone’s natural lens becomes harder, reducing our ability to focus up close, a condition known as presbyopia. This is a natural aging process and has nothing to do with being nearsighted or farsighted. Monovision is a procedure that allows those experiencing presbyopia to regain both near and distance vision without glasses or contacts. With monovision, one eye is corrected for distance and the other for near. This works very well for those who accept this new way of seeing. We always allow candidates to preview monovision with a temporary trial of contact lenses simulating monovision to ensure this new visual arrangement.
An innovative, new procedure to treat presbyopia, is now available at Vivid Laser Centre. The Kamra Inlay is 5 micron thick device used to restore near vision while preserving distance vision in those suffering from presbyopia. It is implanted into the center of the cornea, during a LASIK procedure, in only one eye. LASIK allows both eyes to see in the distance, while the eye with the Kamra Inlay, also has good near vision. This is similar to monovision, with the exception that both eyes retain good distance vision. This procedure is an excellent option for those suffering from presbyopia, who did not like monovision during their contact lens trial.
With cataract surgery or Clear Lens Implantation, the natural lens is removed and needs to be replaced. The new lens implant comes in many varieties. Single focus lenses are the most commonly used lens implants, and focus light to a single point. This results in good distance vision, with glasses required for all other distances (computer, reading). Multifocal or Extended Range of Vision lenses focus light both near and far, producing good distance and near vision without the use of glasses. Multifocal or Extended Range of Vision lenses are useful for those who desire freedom from glasses or contacts after cataract surgery or clear lens implantation surgery.
