Cataract Eye Surgery in Johannesburg, South Africa
Cataracts are the leading cause of blindness worldwide and a common cause of vision loss in older patients. A cataract occurs when the eye’s lens becomes clouded and causes impaired vision. Though the precise cause of cataracts is unknown, most are associated with aging. Diabetes, family history, eye injuries, past eye surgeries, long-term exposure to UV or infrared light, and certain medications are also considered risk factors.
Types of Cataracts
There are three different types of cataracts: nuclear, subcapsular and cortical. The nuclear type gradually affects the entire lens from deep within the nucleus and is associated with aging. The subcapsular type is more common in younger patients and progresses at a faster rate. The cortical cataract creates white, cloudy areas that start on the edge of the lens and move to the center in a striped pattern. This type of cataract affects the lens cortex that surrounds the eye’s central nucleus.
Cataract surgery is the only treatment to fully correct this condition. A refractive test will be performed to evaluate the amount of nearsightedness, farsightedness, and astigmatism you have before surgery. Other measurements of your eyes will be taken to calculate the curvature of your cornea and the length of your eye. During surgery, the affected lens is removed and replaced with an intraocular lens implant (IOL). Johannesburg cataracts surgeon Dr. Guglielmetti offers premium IOLs that require little to no maintenance once implanted. Cataract surgery usually takes about 15 minutes and is an outpatient procedure.
Cataract Eye Recovery
You will be able to go home after surgery, but you will not be able to drive yourself. Dr. Guglielmetti will prescribe medicated eye drops and special post-operative sunglasses to protect your eyes during the healing process. You will also be given an eye shield to wear while sleeping or napping for at least seven days after surgery. Strenuous activity such as heavy exercise must be avoided after your procedure. Most patients experience blurred vision for a few days after surgery, but your vision will continually improve as you recover.
