Intracapsular cataract surgery removes the lens and the entire membrane wrapped around the lens (capsule).

When the whole lens capsule is removed, there is a greater chance of complications in the back of the eye:

• The gel in the eye (vitreous gel) may ooze into the front of the eye, which can then cause the retina to detach (retinal detachment).
• Extensive bleeding may occur in the back of the eye.

Compared to extracapsular surgery, intracapsular surgery has a greater risk of complications, including glaucoma, which may result in nerve damage and blindness.
