Laser Iridotomy

Laser iridotomy is a procedure performed to treat or prevent angle closure, a condition in which the cornea comes into close contact with the peripheral iris resulting in an obstructed anterior chamber angle. The procedure can potentially relieve the obstruction and prevent or reverse elevated intraocular pressure.

Laser iridotomy is performed under topical anaesthesia. Your surgeon makes a small hole on the outer edge of the iris with the help of a focused laser beam. This opens up a passage for the movement of fluid between the anterior and posterior chambers of the eye, allowing the angle between the iris and cornea to open up. Laser iridotomy may be associated with complications such as:

  • Short period of blurred vision
  • Bleeding
  • Swelling of the cornea (clear covering of the eye)
  • High pressure in the eye
  • Closing of the hole
  • Glaring or double vision
  • Recurrence of the condition
  • Occurrence of another type of glaucoma
