What is an anterior vitrectomy? The goals of anterior vitrectomy are to remove the vitreous from the anterior chamber, to clear any vitreous from the entry incisions and to allow an IOL to be placed.
What is an anterior vitrectomy?
The goals of anterior vitrectomy are to remove the vitreous from the anterior chamber, to clear any vitreous from the entry incisions and to allow an IOL to be placed. The bottle height should be greatly lowered, to 15 to 20 centimeters above the eye, before placing the infusion into the anterior chamber.
What is a pars plana vitrectomy mean?
Overview. Pars plana vitrectomy (PPV) is a commonly employed technique in vitreoretinal surgery that enables access to the posterior segment for treating conditions such as retinal detachments, vitreous hemorrhage, endophthalmitis, and macular holes in a controlled, closed system.
What is pneumatic retinopathy?
Pneumatic retinopexy is a procedure to repair a detached retina and restore vision. Unlike other procedures to treat a detached retina, it often takes place in an office setting. The retina is a layer of cells at the back of your eye. These cells use light to send visual information to your brain.
How do you perform anterior vitrectomy?
The first step is to use a dispersive viscoelastic, such as Viscoat or Vitrax, to levitate any mobile lens fragments up toward the cornea. Next, completely fill the anterior chamber with viscoelastic. Even though vitreous has already prolapsed forward, injecting viscoelastic should not exert traction on the retina.
What kind of gas is used in vitrectomy?
Typical gases used are perfluoropropane or sulfur hexafluoride. The gases are mixed with air to neutralize their expansive properties to provide for a longer acting (than air alone) retinal tamponade. The retinal tamponade acts to hold the retina in place or temporarily seal off holes in the retina.
Can I drive with gas bubble in eye?
You cannot fly in an airplane or drive above 1000 feet elevation if you have an air or gas bubble in your eye. Talk to your doctor about the duration of this restriction. When can I shower and wash my hair? You may shower or bathe when you get home, but avoid getting water in your eye during the first 2 weeks.
When is anterior vitrectomy performed?
If lens material becomes dislocated into the vitreous cavity, an anterior vitrectomy can be performed followed by the anterior removal of residual cortex; this technique should not produce vitreoretinal traction.
