12 RISKS AND COMPLICATIONS
The below mentioned side effects are common to cataract surgery.
We know that cataract surgery is one of the safest procedures.
Patients undergoing Prelex are younger and healthier than those
undergoing cataract surgery so the complications are less common.
Corneal Edema or hazy cornea
The fluid used in the surgery may enter into the clear cornea
making it milky causing blurry vision. The inner lining of the cornea is
a pump that actively removes water out of the cornea to keep it clear.
Use of excessive energy or ultrasound in the eye can cause reversible
shock to these cells. Touching the inner surface of the cornea can
permanently damage the cells.
Pre-existing problems with this function of the pump can
predispose to this condition. Cornea edema resolves, with time aided
by the use of hypertonic saline.
Inflammation or Uveitis
Whenever any part of the body is violated it mounts a defense. So
does the eye, which considers the surgery an attack. White blood cells
are liberated into the anterior chamber. Pigment released from the
colored iris, and blood cells add to this mixture. Effects include;
blurred vision, redness and pain. Nonsteroidal anti-inflammatory and
steroid drops aid in resolution. People with a deeply pigmented iris
may take longer to resolve.
Zonular Dialysis/Implant shift
When the support of the lens bag is weak the lens can move from
its well-centered position. Effects could vary from minor glare to
