What you need to know about YAG laser (for secondary cataract)?
The YAG laser is a simple, painless, and short procedure performed in the ophthalmologist’s practice to remove secondary cataract. This is a simple and safe laser treatment commonly used to improve your vision after cataract surgery.
During the cataract surgery, the natural lens inside the eye that had become cloudy is removed. A new artificial lens is inserted into the lens capsule. This capsule can thicken after surgery and may become cloudy, interfering with the light that reaches the back of the eye. When this happens, your vision may become blurry and you may be disturbed by bright light or lights at night. The symptoms may be similar to the initial ones of cataract.
Capsule thickening can occur shortly after cataract surgery, but it more commonly appears a few years after the surgery. YAG laser capsulotomy is the only way to treat this. Secondary cataract does not affect the eye in any way.
In a YAG laser capsulotomy, the doctor uses a special laser to create a small incision in the center of the capsule, allowing light to pass through.
What happens during a YAG laser capsulotomy?
The treatment will be performed as a quick procedure in the doctor’s practice. You will be administered some eye drops to dilate your pupil and anesthetic eye drops to numb the surface of the eye. The laser is similar to the slit lamp used to examine your eyes during a routine check-up, except that it has a special laser attached. The doctor will place a special contact lens on your eye before applying the laser beam. This lens allows the doctor to visualize the capsule more clearly in order to apply the laser and make a small incision in it, to improve vision.
The treatment is painless due to the anesthetic drops and lasts approximately 20 minutes.
When do you know that you need YAG Laser investigation?
The symptoms that require investigation with the YAG Laser are decreased vision, blurred vision, the same symptoms that the patient reports before cataract surgery.
The risks of this procedure
Complications after this treatment are very rare.
Sometimes the pressure inside the eye increases immediately after laser treatment. If this happens, you may need additional treatment before you can go home.
In extremely rare cases, some patients may develop a fluid accumulation in the macula (a part of the eye responsible for detailed central vision). This is called macular edema, which causes blurring or distortion of vision. Another extremely rare complication is retinal detachment, when the thin light-sensitive membrane at the back of the eye separates from the wall of the eye.
If you have the following symptoms, it means you urgently need an examination and possibly treatment:
- excessive pain
- the sudden appearance of floating particles (black spots caused by small pieces of debris floating in the vitreous humor of the eye)
- loss of vision
- flashing lights
- the growth of a red spot on the eye.
If you experience any of these symptoms, contact your ophthalmologist immediately.
