Cataracts are an age-related ocular problem that is responsible for more cases of adult blindness worldwide than any other medical condition. In their earliest stages, they cause blurred vision and noticeable cloudiness of the patient’s lens and can progress to complete blindness if they are not treated. Although most cases of cataracts are due to advanced age, they can affect younger patients, particularly those with high myopia or diabetes.
Symptoms and Diagnosis
The most common early symptoms of cataracts are blurring and yellowing of a patient’s vision, dulling of colors, and the experience of glare at night or under bright light. Those who require vision aids such as glasses or contacts may also find that their prescription changes as the condition progresses. In order to definitively diagnose a patient with cataracts, his or her doctor must perform a comprehensive eye exam to rule out other abnormalities, then use a slit lamp microscope to evaluate the stage of the condition.
The only known treatment for cataracts is the removal of the patient’s natural lens so that it can be replaced with an intraocular lens implant. Most eye doctors recommend that patients have cataract surgery as soon as they begin to notice symptoms.
The surgery required to remove cataracts is a simple procedure that can be performed under local anesthesia right in the doctor’s office. Typically most patients have one eye treated at a time, and each surgery can be completed within just 20 minutes.
During this surgery, an eye surgeon will remove the patient’s lens through a small slit made with a femtosecond laser. Recent innovations in medical technology have allowed for much quicker recovery, and most patients begin to notice improvements in their vision within just a day.
Choosing the Right Lens
Each intraocular lens implant comes with its own strengths and weaknesses, making it extremely important that patients discuss their unique needs with their doctors prior to undergoing surgery. Patients who require mono-focal or multifocal lenses can choose implants that correct their nearsightedness or farsightedness in addition to removing their cataracts. Those suffering from presbyopia can also have specialty lenses implanted to treat the issue.
