Cataract
extraction and intraocular lens implantation has
been reported to be the safest operation performed
on any part of the human body; however, serious
complications occasionally occur. The techniques
of vitreous surgery which were first developed
to repair damage caused by severe diabetes can
be utilized to repair unusual complications of
cataract surgery. An example of this type of complication
would be rupture of a weak lens capsule which allows
a fragment of the cataract to fall back into the
vitreous cavity or onto the surface of the retina.
If this occurs, the safest means of removing the
intravitreal cataract fragment is with vitreous
surgery. Surgery is usually postponed until the
eye is no longer inflamed although some factors,
such as increased intraocular pressure, necessitate
more prompt surgery. Rarely, an intraocular lens
implant can become dislocated into the vitreous
cavity and this can also be repaired by vitreous
surgery techniques. Other complications include
cystoid macular edema which can be managed with
Diamox, subtenons' steroids and occasionally vitreous
surgery. With a Choroidal/Expulsive Hemorrhage
you need to wait for the blood to liquify then
perform vitreous surgery.
