YAG Laser

Why (Purpose of the Procedure)

  • Although cataract surgery removes the cloudy natural lens and replaces it with a clear intraocular implant, the back layer of the lens (posterior capsule) is left to support the implant.
    • Over time, natural cell growth can make this capsule cloudy, interfering with clear vision.
    YAG laser treatment restores vision by removing this cloudiness without needing another surgery.

What (Condition Being Treated)

  • The YAG laser procedure treats a condition called posterior capsular opacification (PCO), also known as a “secondary cataract.”
  • This occurs when the thin membrane (posterior capsule) left behind during cataract surgery becomes cloudy over time, blurring vision again.

How (Procedure and Process)

    YAG laser capsulotomy is a quick, painless outpatient procedure done under topical anesthesia.
  • The eye is numbed with anesthetic drops.
  • A special laser (YAG laser) is precisely aimed at the cloudy posterior capsule behind the intraocular lens.
  • The laser creates a clear opening (a “window”) in the capsule to restore the pathway for light and improve vision.
  • After the procedure, intraocular pressure is monitored to ensure safety.
