Cataract Surgery has for many years, never ceased to evolve.
What is a Cataract?
Inside of your eye there is a structure called the lens which is mainly composed of proteins and water. With the ageing process, these proteins accumulate and gradually form a veil which prevents light to reach the retina and alter the vision process. Some symptoms may be a decrease of central or peripheral vision, blurs, difficulty driving, reading etc…
A sight examination will confirm there is a cataract.
It used to be that the main purpose of the ophthalmologist was to get rid of this condition by inserting an intraocular lens and correct mainly the distance vision. Nowadays there are many types of intraocular lenses which allow the surgeon to implant a lens that addresses your visual health and your specific needs in terms of vision. Since your eye is different from your neighbor`s, your personal needs have become the prime target.
Intra-Ocular Lenses to Correct Astigmatism (Toric Lenses)
If you have astigmatism the surface of your eye is more oval than round. This condition alters the quality of your vision. This irregularity is fairly frequent and deforms both close-up and distance vision. People who have astigmatism generally wear glasses or contact lenses to be able to see clearly. As a rule after a cataract surgery people have fairly good distance vision. Unfortunately for people having astigmatism on top of the cataract, the surgery will give good results only if the astigmatism is corrected. Now this can be done with implanting a toric lens in the eye.
Multifocal Lenses to Correct Nearsightedness
Even if the distance vision is well corrected after a cataract surgery, close-up vision will be blurred without an additional bifocal to correct this particular case of nearsightedness or presbyopia. Nowadays the multifocal intra-ocular lenses will provide good vision for both distance and close-up.
Kirkland and District Hospital
All these lenses are now available at the KDH. Supplementary tests will be needed to validate your condition and accurately calculate the lens that fits your eye. For more information contact the Specialist Clinic at 705-568-2110.
