CAPSULAR CATARACT Meaning and
Definition
-
Capsular cataract is a medical condition characterized by the clouding or opacification of the lens capsule, which is the thin, transparent membrane that surrounds the lens of the eye. This condition typically occurs as a result of aging or certain medical conditions, such as diabetes or uveitis.
The lens capsule plays a crucial role in maintaining the overall shape and clarity of the lens, allowing it to properly focus light onto the retina. However, in cases of capsular cataract, the lens capsule becomes stiff and loses its elasticity, leading to the accumulation of damaged lens proteins and the formation of cloudy or opaque areas.
Symptoms of capsular cataract may include blurry or cloudy vision, sensitivity to light, increased difficulty seeing at night, and the presence of halos or glare around lights. The severity of symptoms can vary depending on the extent of opacification in the lens capsule.
Treatment for capsular cataract typically involves surgical intervention, such as a procedure known as phacoemulsification. During this surgery, the cloudy lens is removed and replaced with an artificial intraocular lens (IOL) that can restore vision and improve visual clarity. Post-operative care often involves the use of eye drops and regular follow-up visits with an ophthalmologist to monitor healing and address any complications that may arise.

Etymology of CAPSULAR CATARACT
The word "capsular" comes from the Latin word "capsula", meaning "a small box or case". It evolved through French into English, referring to anything that relates to or is enclosed in a capsule or a small container.
The word "cataract" has a different etymology. It comes from the Latin word "cataracta", which means "waterfall". The word was used in ancient Roman medicine to describe a condition where there is a "waterfall-like" opacity or clouding of the lens in the eye.
When we combine these two terms, "capsular cataract" specifically refers to a type of cataract that affects the capsule surrounding the lens of the eye.
