Cataracts

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 as medications nor glasses cannot corrects this medical problem.
                       
Can cataracts come back? No,  cataracts 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 generally 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. Some patients receive a Toric lens to correct astigmatism, however this lens procedure is not covered by health care and has additional cost associated.
          
Dr. Bozdech routinely utilizes the most modern technique in cataract surgery called "Clear Corneal Surgery Under Topical Anesthesia". This means that most cases are performed under topical anesthesia, consisting of numbing drops and ointment only.  In otherwords, in layman's terms a "no needle surgery", unless circumstances dictate otherwise.  This completely prevents needle associated complications such bleeding behind the eye and needle -associated discomfort, inadvertent ocular perforation leading to blindness, reduced vision or double vision by damaging the muscles/nerves controlling  the eye movements.
                   
During cataract surgery Dr. Bozdech makes two very small corneal incisions 2.75 mm and the other around 1 mm.  Both incisions are performed through the cornea to avoid blood vessels and prevent conjuctival scarring.  Sometimes this approach can reduce prexisting corneal astigmatism. Another advantage is that this surgery can be performed successfully in people with bleeding disorders or on blood thinners in the event they cannot discontinue their medications preoperatively.
