Mature cataract in the eye (Video)

This video shows a dense cataract in the eye. This lens has opacified to the point that it can be seen without a microscope, and is severely limiting vision.

We don’t see many cataracts like this in the U.S. as most people have surgery long before.

White cataract
This photo is of a dense white cataract. We don’t see many of these here in the US, as most people have theirs removed long before this stage. The lens is white and has a mother-of-pearl or marble appearance.
4+ Cataract
The slit-lamp beam hilights the surface of this lens and you can appreciate the refractive patterns.

  1. wish you could show a video on posterior subcapsular cataract. would be great as some of the med students still have difficulty detecting it.. Could you also do a video teaching us how to use the slit lamp to do specular reflection, direct illumination, transillumination, etc the various techniques mentioned in books(eg the AAO series of books)? That would have been a great help! thanks so much for the wonderful videos so far
