CATARACT SURGERY Meaning and
Definition
-
Cataract surgery is a medical procedure performed to remove a cataract, a clouding of the lens in the eye that affects vision. The surgery involves extracting the affected lens and replacing it with an artificial lens to restore clear vision.
During cataract surgery, the patient typically receives local anesthesia or sedation to numb the eye and reduce discomfort. The surgeon makes a small incision in the cornea, the clear front part of the eye, to access the lens. Advanced techniques, such as phacoemulsification, may be used, where high-frequency sound waves are used to break the cloudy lens into fragments, which are then removed through suction. Alternatively, in cases of more severe cataracts, the entire lens may be removed through a larger incision.
After the cataract is removed, the surgeon places an intraocular lens (IOL) inside the eye to replace the natural lens. These IOLs are made of clear plastic or silicone and are designed to restore the eye's focusing power, leading to improved vision. Different types of IOLs are available, including those that correct common vision-related issues like astigmatism or nearsightedness.
Cataract surgery is considered a safe and effective procedure, with a high success rate in improving vision and quality of life for patients with cataracts. It is commonly performed on an outpatient basis, allowing the patient to go home on the same day as the surgery. The recovery period is relatively short, with most patients experiencing improved vision within a few days to weeks after the procedure. However, it is essential to follow the post-operative instructions provided by the surgeon to ensure proper healing and optimal visual outcomes.

Etymology of CATARACT SURGERY
The word "cataract" derives from the Latin term "cataracta", which originated from the Greek word "kataraktēs", meaning "waterfall". This term referred to a rush of water or a strong downpour. The association between waterfalls and eye conditions may have stemmed from the visually impaired experiencing blurred vision, similar to the way water blurs one's ability to see clearly.
The word "surgery" comes from the Latin term "chirurgia", which is a combination of the Greek words "cheir" (hand) and "ergon" (work). Therefore, "surgery" essentially refers to the manual or handwork performed to treat a medical condition.
