Glaucoma is a group of eye disorders that can occur in vision loss and blindness by damaging the nerves in the reverse of your eye called the optical nerve. This type of surgery is used to treat several types of glaucoma, including infantile glaucoma, neovascular glaucoma, and glaucoma caused by an injury. It’s done in a medical center and generally takes 1 to 2 hours.
In this operation, the surgeon implants a mini tube, or shunt, onto the white part of your eye. The tube helps additional fluid drain out of your eye, lowering your eye pressure, Generally, you’ll be awake during this surgery but you’ll get medicine to help you relax. You can generally go home the same day, but you’ll need someone to drive you home.
Glaucoma surgery can have any effect, just like any operation. For e.g, your eye may be swell and sore for a while.
Other possible chances of glaucoma surgery include
• Problems with the cornea
• Eye pressure that’s too low
• Vision loss
• Red spot
• You feel like that small object in your eye
The most ordinary type of surgery for glaucoma is known as trabeculectomy. It involves removing part of the eye- drainage tubes to allow fluid to drain more fluently.
Other types of glaucoma surgery include
• trabeculectomy – analogous to trabeculectomy, but an electric current is used to remove a small part of the eye- drainage tubes
• viscocanalostomy – part of the white external covering of the eyeball( the sclera) is removed so fluid can drain from your eye more fluently
• deep sclerectomy – the drainage tubes in your eye are widened, occasionally by implanting a mini device inside them
• trabecular stent bypass – a mini tube is placed into your eye to increase the drainage of fluid
After surgery, your eye might water and be red, and your vision may be slightly blurred for over 6 weeks but should return to normal.
Recovery from glaucoma surgery differs, based on the surgery. “ Visual recovery can be rapid with small meddling procedures, like minimally invasive glaucoma surgery( MIGS), because they don't gravely change the structure or shape of the eye.“ More traditional surgeries can drop the pressure mainly or occur blurriness from presbyopia associated with suturing. ”
“Still, recovery can be reduced by the inflexibility of glaucoma and other confliction factors, similar as blood thinners or the eye’s reaction to the procedure, Mostly people notice recovery in vision within a week after the surgery. Cases of monthslong recovery are also possible, although veritably uncommon.”
Avoid these conditions during the first weeks after surgery
• Exercise, similar to running, or lifting further than 10 pounds
• Bending, lifting, or straining
• Swimming or using a hot cask; depending on the surgery, there may be a lifelong safety in this regard
• Wearing applicable contact lenses; Occasionally the surgeon will place a specific contact to quicken mending.
• Wearing eye makeup or face cream.
Your opthalmologist will review your medical history and conduct a comprehensive eye examination.
Consultant may perform several tests, including
• Measuring intraocular pressure( tonometry)
• Testing for optical nerves damage with a widened eye examination and imaging tests
• Examine for areas of vision loss( visual field test)
• Measuring corneal consistency ( pachymetry)
• Examining the drainage angle( gonioscopy)
