Laser Iridotomy

• A laser iridotomy involves the use of a laser to create a hole in the iris. This hole enhances drainage passages that are otherwise blocked by the portion of the iris that is affected by glaucoma.
  
  

Common Side Effects

• The single most common side effect of an iridotomy is briefly blurred vision, usually lasting about 30 minutes. Less common is swelling of the cornea, bleeding, and increased pressure in the eye.
  
  

Complications

• Other complications may include a closure of the new opening, which might require a second surgery. Other risks include a burn to the inner lining of the eye, and other types of glaucoma developing. Extremely rare are cases of pupil distortion or rupture of the lens capsule.
  
  

Long Term Side Effects

• Laser iridotomy patients may experience long term side effects, such as a worsening of the clouding of the lens present before the treatment, and glare from light entering the new opening. Some patients also complain of a horizontal line in their vision.
  
  

Important Considerations

• Closed angle glaucoma usually affects both eyes over time, and thus, the unaffected eye is usually also treated to prevent onset. Also, a continued need for glaucoma medications may occur even after treatment.
