Laser eye treatment, or Lasik, surgery helps people see better without glasses. Some people have reported that after surgery, they have floaters--sometimes visible, moving flecks or spots in their vision. Floaters are a side effect of laser eye surgery.

Definition

Normally the vitreous humor that fills the eyeball is transparent. Sometimes there are tiny specks or spots that move around in the gel of the eye. You can see a shadow of this small particle when light hits your eye.

Causes

During laser surgery, the surgeon cuts into the cornea to create a flap that is pulled aside. At the end of the surgery, the flap is closed. Sometimes this flap does not adhere properly to the eye, and it develops wrinkles that cause floaters.

Problems

Floaters are usually not a problem unless there are so many of them that it affects your eyesight. If there are flashes of light that appear with the floaters or blood is present, there is a possibility of retinal detachment. Contact your surgeon if you have these symptoms.

Time Frame

Due to natural processes within the eye, floaters can eventually be absorbed. They may slowly diminish in size as time goes on. You will also become less aware of them over time.

Further Surgery

The vitreous humor can be removed from the eye along with the floaters in a procedure called a vitrectomy. The surgeon then refills the eye with clear fluid. This is usually done only if there is blood or scar tissue that affects sight.
