Cataract Surgery

What is a Cataract? A cataract is a clouding of part of the eye known as the lens through which light enters the eye. When normal, the lens is clear and is located just behind the iris (coloured part of the eye). There are many causes for cataracts. These include:
          
• age
• genetics
• trauma
• diabetes
• sun exposure
• cigarette smoking.
• certain drugs such as steroids
         
Cataracts are treated with surgery when they get to the point of affecting a person's life by limiting vision.
                                    
Can cataracts come back? No, the cataract cannot regrow. However, sometimes the posterior capsule becomes opaque and needs to be divided with the YAG laser. This usually only occurs once, so you will not need to have this done again.

When Dr. Bozdech performs cataract surgery he uses the Alcon's AcrySof SN60WF artificial foldable lens which had been shown to reduce the risk of  postoperative posterior capsular opacification as compared to other implants available on the market. Furthermore, the AcrySof SN60WF lens is especially designed and patented to reduce the harmful effects of visible and ultraviolet light on the retina which is particularly important in the prevention and progression of macular degeneration. In suitable cases a Toric lens may be offered in order to correct pre-existing astigmatism. This refractive procedure is done to reduce spectacle dependence for distance vision.  
           
Dr. Bozdech performs most of the cataract surgeries under topical anesthesia, meaning that the eyes are frozen with drops and ointment only (rather than the needle - the old way of doing cataract surgery).  In a small percentage of cases a needle or general anesthesia may still be necessary depending on special circumstances (patient cooperation and anticipated surgical complexity). The advantage is that one can avoid needle associated complications which can result in double vision or blindness.
