PROGRESSIVE CATARACT Meaning and
Definition
-
Progressive cataract is a medical condition characterized by the gradual clouding or opacity of the lens in the eye, leading to the deterioration of vision over time. It is a type of cataract that develops gradually, often in older individuals, and worsens progressively as the lens becomes increasingly opaque.
Cataracts in general are a common eye problem that affects the clarity of vision. They can occur due to aging, long-term exposure to ultraviolet light, certain medical conditions (such as diabetes), trauma to the eye, or as a result of certain medications. However, progressive cataracts specifically refer to cataracts that worsen gradually and require intervention as they impair vision.
The symptoms of progressive cataract may include blurred or hazy vision, increased difficulty seeing in low light conditions, glare sensitivity, or the appearance of halos around lights. Over time, these symptoms can escalate, leading to significant visual impairment or even blindness if left untreated.
Treatment for progressive cataract usually involves surgical removal of the clouded lens and replacement with an intraocular lens implant to restore clear vision. Cataract surgery is a safe and common procedure that can be highly effective in restoring visual acuity and improving the quality of life for individuals with progressive cataracts. Regular eye examinations are important for early detection and management of progressive cataracts to ensure timely intervention and optimal vision outcomes.
