Vitrectomy
The transparent vitreous gel can be firmly attached to the retina. In this photo, the white circle highlights its main point of attachment to the retina. Before removing the vitreous, I gently separate it from the retina. This separation allows the white circle to cast its shadow onto the retina.
What is a Vitrectomy?
Vitrectomy refers to the surgical removal of the vitreous gel. This gel is the scaffold that allows the eye and retina to form properly when we are babies developing in the womb. It fills the cavity inside the eye between the iris and retina.
The vitreous gel is important for two reasons:
It may cause retinal problems as it naturally breaks down and turns into liquid, and
It must be removed to allow us to repair the retina.
How do you perform a vitrectomy?
To remove the vitreous, I use microscopic instruments through incisions made in the white of the eye. The gauge of the vitrectomy refers to the size of the instruments used. I utilise the smallest gauges (25g and 27g) currently available. These incisions are less than a millimetre in size, heal quickly and often do not require any sutures.
The vitreous is gently removed and replaced with a specially-designed salt solution. Within a short period, the eye replaces this with its own natural fluid.
As mentioned above, the vitrectomy is often only the first part of the operation. Following this, the epiretinal membrane is peeled, the retinal detachment fixed or macular hole repaired.
Some operations may require an air or gas bubble to help the retina to recover. This bubble prevents you from seeing well while it is inside the eye. Your vision will improve as it is naturally absorbed.
Where will my surgery take place?
If you require a vitrectomy, I operate at the Nuffield Health Bristol Hospital. Vitrectomy is usually performed as a daycase procedure under local anaesthetic. It can be combined with cataract surgery if necessary. General anaesthetic can be requested if preferred.
How long is the recovery for a Vitrectomy?
The recovery period following surgery is usually two weeks. Certain activities such as driving or flying should be avoided while the gas is present inside your eye.
