This video shows an eye suffering from severe pseudoexfoliation syndrome of the lens. This has caused glaucoma and will make his cataract surgery difficult. In this movie, you can see the white PXF material on the surface of the lens – it looks radially oriented because the iris rubs against the lens at this point….
This video shows a cluster of Elschnig pearls that have formed behind the lens after cataract surgery. These grape-like clusters form from residual lens epithelial cells that migrate along the remaining capsular bag. They can be seen with a microscope and are usually visually insignificant. When epithelial cells form in the central visual axis, this…
This video shows a cataract lens that has dislocated backwards after blunt trauma. You can even see a veil of vitreous coming around the lens into the anterior chamber. This cataract will be difficult to remove, as an anterior approach is unsafe (there is too much zonular dehiscence such that the lens might fall into…
In this video, you can see the normal suture lines that form in the lens with normal eye development. In the front of the lens is a “Y” while in the back, the “Y” is inverted (like a mercedes sign). This is a subtle finding and easier to see in a young eye. Certain types…
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. Download this video To download this video, right click…
In this video you can see what a typical cataract looks like under the microscope in real life. The central nucleus has turned brunescent (yellowish) such that this patient is suffering from decreased vision that is exacerbated by bright lights. The lens is constructed with three components and has a configuration similar to a “peanut…
This video shows a hypermature morgagnian cataract. As you can see, the cortex has liquefied and turned milky, while the central nucleus has turned brown and sunken to the bottom of the capsular bag.

This video shows an anterior polar cataract sitting on the front surface of the lens. The forward placement of these opacities cause less visual disturbance than you might think from it’s appearance.
