Editorial brief only. This is not finished article copy and must not be published.

Complete the article in original language, verify every medical claim against the listed sources, and obtain a real clinician review before changing its status.

Primary keyword

posterior subcapsular cataract

Audience

Patients told they have a specific cataract type and want to understand it

Editorial angle

Explains why two people with 'cataract' can have very different symptoms and timelines, with a type-by-type table the current results lack.

Facts to source and verify

Nuclear cataract hardens and yellows the centre of the lens and can temporarily improve near vision ('second sight'); cortical cataract starts as spoke-like opacities at the edge of the lens and causes glare; posterior subcapsular cataract forms at the back of the lens, affects reading and bright-light vision early and is linked to steroid use and diabetes; congenital cataract needs early assessment in babies to prevent amblyopia
