Intraocular Lens Surgeries
Sometimes there can be damage done to the fibers that hold the natural lens capsule in place. These zonules surround the capsule 360 degrees and things like Pseudoexfoliation Syndrome or trauma can cause it lose a few fibers. There is no problem if it is only a few, but a focal loss can cause the IOL to shift in the direction opposite to the area of weakness.
The IOL on the left will cause tremendous astigmatism, glare and haloes because of seeing the edge of the IOL. Treatment for this is surgical and necessitates suturing of the IOL to sides of the eyeball wall, to act where the lost zonules cannot. Keeping the present IOL is usually preferable as the recovery is much faster. If the IOL cannot be sutured back into place, then it can be exchanged.
In an IOL exchange, the IOL is removed from the eye and replaced with a different IOL. The difficulty of the surgery depends on where the original IOL was placed and how long it has been scarred into place. Some IOLs do not match well to every cornea and some multifocal IOLs can be intolerable for some patients. In cases where conservative management fails and the patient is unhappy with the visual outcome, it is best to remove the IOL and replace it with a different IOL catered better to the patient’s desires.
If you are suffering with an IOL that you feel is compromising your vision perhaps a IOL surgery is an option. Come see us at Orlando Eye Institute. We will first see what we can do to help with your symptoms. It may be something as simple as treating dry eye syndrome. If necessary, however, the IOL can always be removed and replaced.
