Secondary cataracts These generally develop following eye surgery
, particularly associated with glaucoma or a retinal condition. Diabetes or prolonged steroid use may also cause secondary cataracts.
Traumatic cataracts These form as a result of an injury or trauma to the eye. You may develop traumatic cataracts right after the injury, or it may take several years for the condition to appear. Blunt trauma to the eye and chemical exposure are the two biggest risk factors for traumatic cataracts.
Congenital cataracts These develop at birth. In mild cases, you may not experience much in the way of vision problems. However, severe congenital cataracts may need to be removed in order to prevent other vision issues such as strabismus or amblyopia.
Radiation cataracts While very rare, it is possible that certain types of radiation, particularly ultraviolet light radiation, may cause cataracts.
