Specular Microscopy

Specular Microscopy is a test that measures the quantity and quality of corneal endothelial cells. This information is necessary to perform a surgery and to reach a suitable visual diagnosis for each patient.

Why the test is performed:

Corneal endothelial cells count is necessary when:

  • Testing the health of the cornea is required
  • Presence of dystrophies at a corneal level
  • Suspicion of corneal dystrophies
  • Corneal transplant patients
  • Corneal trauma
  • Bullous keratopathy
  • Recurrent epithelial erosions
  • Secondary intraocular lens transplant
  • Patients who are about to undergo phakic intraocular lens implant
  • Patients who already have an intraocular procedure, and will undergo cataract surgery

Before undergoing any surgical intervention that involves working inside the eye or in the cornea, it is necessary to evaluate its capacity to keep its transparency after the procedure.
This transparency is essential in order to have a good eyesight in the operated eye, and it directly depends on the cell population of the endothelial layer of the cornea. The better the endothelial layer is, the faster the recovery of the patient will be after the surgery, and the lower the risk of a secondary cornea transplant, or any other difficulty in the long or short term.

How to prepare for the test:

This is an easy to perform test that does not require a dilated eye. It lasts approximately 5 minutes.
The transparency of the cornea is essential to its performance.
