Vitrectomy Eye Surgery
Vitrectomy eye surgery was established in 1970 by Robert Machemer. The procedure involves the removal of
vitreous from the eye. Vitreous, also known as vitreous humor, is a gel-like liquid found between the lens and the
retina of the eye. Vitreous is clear but has a very similar texture to egg white. It provides cushioning support for the eye without restricting
access of light into the eye.
Since 1970, Vitrectomy eye surgery has been developed
extensively and now includes additional surgical steps making it effective in correcting retinal problems in addition to vitreous
problems.
Retinal Detachment and Intraocular Infection (an infection inside the eye) are the most common
conditions treated with this type of eye surgery.
After the vitreous is removed it is gradually restored as the eye secretes aqueous and nutritive fluids.
Scar tissue, blood and other debris can also be removed from the eye with this procedure. Blurred vision can be caused by erroneous debris
collected in the vitreous.
Other conditions affecting the eye that may need Vitrectomy eye surgery are:
§ -
Injury or infection
§ -
Problems related to an earlier surgery
§ -
Pre-retinal membrane fibrosis
§ -
Retinal detachment
§ -
Haemorrhaging in the eye
§ -
Complications from diabetic retinopathy
§ -
Macular hole
Vitrectomy eye surgery - procedure
Vitrectomy eye surgery is generally completed under a
local anaesthetic using a microscope with a special lens providing the surgeon with a clear view of the back of the eye. Three
very small surgical instruments, a light rod, an infusion port and a Vitrectomy cutting device are placed in minute incisions made in the pars
plana of the eye (located between the iris and retina). The purpose of the instruments is to light up the inside of the eye, to keep the eye’s
shape during surgery and to remove the vitreous humour.
The infusion port replaces lost fluids in the eye maintaining pressure inside the eye during and after
surgery.
After the Vitrectomy eye surgery
An eye patch will have to be worn until the eye is able to blink normally. Once the
eye patch is removed you will have to use
antibiotic and anti-inflammatory
drops.
Any swelling can be reduced with ice compresses. Aching, pain or soreness may be treated with Tylenol or
other over-the-counter pain killers. You need to contact your surgeon if there is no relief.
Redness in and around the treated eye and a bruised appearance near the corner of the eye is quite
common.
While sleeping you will be required to wear a plastic eye shield for 7 days after
surgery. There will be restrictions on your activity such as lifting heavy objects, bending over and
stooping. Question your doctor about any precautionary steps that you should follow.
Vitrectomy eye surgery - rates of recovery
Your recovery from Vitrectomy eye surgery will depend on the amount of damage to your eye prior to the
surgery and how successful the procedure is. Your surgeon is the only person able to advise on the possible rate of recovery. All surgeries
involve risk. Please consult your doctor any questions or concerns that you have before the surgery.

is part of the uvea, choroidea, one of the three layers that comprise the eye. It is about 4 mm long and located near the point where the iris
and sclera touch.- source Wikipedia
