Types of Cataracts
Nuclear Cataracts
Nuclear cataracts affect the centre of your lens and can cause nearsightedness early in its development. In some cases, it may also temporarily improve your distance vision, but as it develops, it can cause your lens to turn a yellowish or brownish colour.
Cortical Cataracts
Cortical cataracts develop as wedge-shaped streaks around the outer edges of your lens. These wedges can grow over time, eventually affecting your entire lens.
Posterior Subcapsular Cataracts
Posterior subcapsular cataracts develop at the back of your lens, creating a small opaque area directly in the path of light reaching your retina. This form of cataract can develop quickly, causing glare from lights and reducing your near vision.
Congenital Cataracts
Congenital cataracts form when you’re born or during childhood. This type of cataract can be genetic but can also develop if you have conditions like myotonic dystrophy, galactosemia, neurofibromatosis type 2, or rubella.
