SPECULAR MICROSCOPY

Specular microscopy is a non-contact diagnostic eye imaging service that evaluates the health and density of corneal endothelial cells. These cells maintain corneal clarity by regulating fluid balance. Therefore, accurate assessment helps your ophthalmologist detect early endothelial damage, monitor disease progression, and plan eye surgery more safely.

WHAT THIS SERVICE DOES

This test captures a magnified image of the corneal endothelium, the innermost corneal layer. It measures endothelial cell density, cell size variation, and cell shape. In addition, it assesses corneal thickness. Consequently, doctors gain objective data that routine slit-lamp examination cannot provide.

The results guide clinical decisions in patients at risk for corneal decompensation. Moreover, serial scans allow reliable monitoring over time.

WHEN SPECULAR MICROSCOPY IS RECOMMENDED

Ophthalmologists request this test when corneal endothelial health may affect vision or surgical outcomes. For example, it is commonly used in the following situations.

1. Preoperative assessment for cataract surgery
2. Evaluation before intraocular lens exchange or implantation
3. Monitoring of Fuchs endothelial corneal dystrophy
4. Assessment after eye surgery or trauma
5. Long-term contact lens use evaluation
6. Investigation of unexplained corneal edema

HOW THE TEST IS PERFORMED

The procedure is quick and non-invasive. First, you sit in front of the imaging device and place your chin on a support. Next, you look at a fixation target while the camera captures the corneal image within seconds. During the scan, nothing touches the eye. As a result, the test remains comfortable and low risk. Most sessions are completed in a few minutes.

PATIENT COMFORT AND SAFETY

Specular microscopy uses safe light-based imaging and requires no eye drops, needles, or contact instruments. Because there is no contact, infection risk is extremely low. Most patients feel no discomfort. In addition, normal activities may be resumed immediately after the test.

WHY ENDOTHELIAL HEALTH MATTERS

Healthy endothelial cells keep the cornea clear. When cell count drops or cell shape becomes abnormal, the cornea may swell and vision may blur. Therefore, early detection helps guide treatment timing and surgical planning. Accurate measurements also help reduce postoperative complications and improve long-term visual outcomes.
