If the zonules are weak,such as from extreme age, pseudoexfolation syndrome,
or old injury, the zonules may not be strong enough to hold the capsule in
place during surgery. If that happens, the zonules "unzip", and the capsule
becomes free-floating. Then it must be removed, or it floats around. If the
cataract is still inside the capsule, it too is remains in the eye unless it
is removed before the capsular bag falls back into the vitreous cavity.
Don't know why there would be blood in the eye - it is not caused by the
capsule or zonules separating.
Pressure will go up int the eye after surgery in complicated cases. Once the
capsule tears, or the zonules rupture, vitreous presents to the anterior
chamber, and must be removed (anterior vitrectomy) using specialized
instruments. The extra manipulationin the eye, plus having to leave some
viscoelastic (the gel used during surgery0 in the eye can raise pressure to
high levels the next day.
You cannot replace the capsule; it is attached to the eye by the zonules
(fibers) that cannot be reattached.
There must have been some bleeding into the vitreous of the eye for some
reason, or a choroidal hemorrhage, which is beneath the retina and occurs
due to the low pressure in the eye when it is opened for surgery, and in
elderly people especially can cause bleeding in the choroid. It is not
caused by instruments damaging that area, just having fragile blood vessels.
Choroidal hemorrhages generally reabsorb (ie 1 month) but sometimes require
a retina specialist to drain them.
Lots of things can happen during surgery, and are part of the risks
involved. Of course, if the surgeon really did something bad, that is one
thing. In general, these complications can occur with any surgeon at some
point.
If there is no capsular support for a posterior chamber lens, the options
for implant later are: anterior chamber lens (a tried and true backup lens
for cases such as this), or a sutured-in [posterior chamber lens, where the
IOL is sutured through the wall of the eye where the capsule would have held
it before. This entails much more manipulation in the eye, with its
attendant risks. The A/C IOL is preferred for its rapid speed of
implantation, with very little open-time for the eye and virtually no
manipulation. Manipulation in the eye can also increase risk of corneal
decompensation.
A second opinion would be a good idea, but the doctor may not know all the
details of the surgery and the complications.
