- It is used when intraocular pressure cannot be reduced with medication.
- It eliminates the need for medications related to living.
- It is a procedure that prevents further damage to the optic nerves.
Trabeculectomy:
- This is a procedure in glaucoma treatment where a part of the trabecular meshwork and adjacent structures of the eye are removed to reduce intraocular pressure.
- It is the most common glaucoma surgery performed.
Ahmed Valve:
- It is used when traditional glaucoma surgery fails.
- It involves placing a silicone channel into a hole created to prevent further damage to the optic nerve.
- With the help of the channel, the eye pressure does not drop to zero, but it remains controlled and does not rise.
SLT (Selective Laser Trabeculoplasty):
- It is used in open-angle glaucoma.
- A low dose of laser energy is directed to blocked canals, and cells containing pigment (melanin) are destroyed.
- This helps to reduce intraocular pressure.
