Posterior Capsulotomy after cataract surgery
A posterior capsulotomy is a surgical laser procedure that may be necessary after
cataract surgery.
During cataract surgery part of the front (anterior) capsule that holds the lens
is removed. The clear back (posterior) capsule remains intact. As long as that capsule
stays clear one has good vision. But in 10 to 30% of people, the posterior capsule
loses its clarity. When this happens, an opening can be made in the capsule with
a laser (posterior capsulotomy) to restore normal vision.
Before the laser procedure, the ophthalmologist does a thorough ophthalmic examination
to make sure there is no other reason for vision loss.
A posterior capsulotomy is painless and takes five minutes. Eye pressure is taken
a half hour after the operation to make sure it is not elevated and accordingly
topical eye drops could be prescribed for a few days following the procedure. Vision
should improve within hours.
An image of a successful capsulotomy is as follows:
Potential but rare complications following laser posterior capsulotomy are increased
intraocular pressure and retinal detachment and other issues that will be discussed
in greater detail if you elect to have this laser treatment.
