Cataract is the cloudiness of the normally transparent natural lens of the eye resulting in diminished vision. The most common cause of cataract is the ageing process. The only effective remedy is surgery i.e Phacoemulsification with IOL (Intra Ocular Lens) implantation. In the first stages of a cataract, people may notice only a slight cloudiness as it affects only a small part of the lens, the part of the eye that focuses light on the retina. As the cataract grows, it blocks more light and vision becomes cloudier. As vision worsens, the surgeon will recommend cataract surgery, usually phaco, to restore clear vision. With advancements in cataract surgery such as the IOL patients can sometimes experience dramatic vision improvement.
Diagnosis / Preparation -
An A-scan measurement, which determines the length of the eyeball, will be performed. This helps determine the refractive power of the IOL. Other pre-surgical testing such as a chest x ray , blood work, or urinalysis may be requested if other medical problems are an issue.
