¿Qué es la vitrectomía?

Vitrectomy is one of the most complex surgical techniques in intraocular microsurgery. It was developed by German-born Robert Machemer, who emigrated to the United States and performed the first procedure in April 1970.

The surgery involves working inside the eye with specialized instruments that perform multiple functions, such as cutting the vitreous, removing membranes, coagulating the retina, repositioning the retina, and sealing retinal holes.

What does the treatment achieve?

  • Removal of abnormal blood vessels that grow on the retina and severely affect vision.
  • Repositioning of the retina back into place.
  • Removal of diseased or cloudy vitreous: when the vitreous (the transparent substance filling the back of the eye) becomes opaque, it can be replaced with a clear solution, allowing light to once again pass through to the retina.
  • Other applications: removal of foreign bodies inside the eye, elimination of bacteria in severe infections, or obtaining samples from within the eye for complex diagnoses.

Are there possible complications?

As with any surgical technique, complications may occur, although they are less frequent in the hands of experienced surgeons.

How is the procedure performed?

Like most microsurgical eye procedures, vitrectomy is usually done under local anesthesia on an outpatient basis, and patients typically do not experience pain.

Overall, more than 85% of patients benefit from this surgery.

What post-operative care is required?

After surgery, relative rest is recommended. In some cases, patients may be instructed to maintain a specific head position, as advised by their surgeon.
