Keratopachymetry (Corneal Pachymetry) in Moscow: Why It's Necessary and How It's Performed
An accurate assessment of the anterior segment of the eye is essential for proper and safe treatment. Modern corneal diagnostics allow for early detection of pathologies and the prevention of complications.
We'll explain in detail how this ophthalmological examination is performed and why it's essential for patients.

When do we recommend corneal pachymetry?
We prescribe this test in strictly defined cases requiring a detailed tissue examination. For clarity, we provide a basic list of medical indications.
When corneal pachymetry is necessary:
- Before planned laser vision correction surgery
- If keratoconus is initially suspected
- If glaucoma is diagnosed and there is a risk of complications
- After eye injuries
- During a comprehensive vision diagnosis
Each item on this list requires the utmost responsibility from the specialist. Analysis of the indicators allows the doctor to choose the appropriate patient management strategy.
Suspected keratoconus and other corneal changes
Sometimes tissue thinning is asymptomatic and unnoticeable. If a doctor suspects keratoconus, the procedure becomes absolutely mandatory. Timely corneal pachymetry helps confirm or refute this serious diagnosis.
Preparation for laser vision correction and other surgeries
Before any surgical intervention, the surgeon needs to know the precise parameters of the eye tissue. Safe laser vision correction is physically impossible without these calculated data. This examination is also always relevant if complex refractive surgery is planned.
Monitoring for glaucoma and elevated intraocular pressure
Evaluation of the ocular membrane structure directly affects the tonometer readings. If the patient has glaucoma, it is crucial for the doctor to adjust for individual tissue density values. In this condition, intraocular pressure is measured solely based on these figures.
How is the examination carried out in our clinic?
The patient sits in a comfortable chair, while the medical staff adjusts the device. The entire procedure takes minimal time and is painless. Our main goal is to make the diagnostic test as comfortable as possible.
Contactless and Ultrasound Methods
Depending on the clinical task, contact or remote measurement is used.
- Rapid, contactless diagnostics are ideal for initial screening.
- In turn, classic ultrasound pachymetry requires a light touch with a special transducer.
How long does the procedure take and is any preparation necessary?
The entire process takes just a couple of minutes for both eyes. The patient does not require any complicated preparation for the examination. If you regularly wear contact lenses, our ophthalmologist will inform you in advance of the need to temporarily stop wearing them.
How to behave correctly during the measurement process
During the optical scan, it's important to look directly at the illuminated mark and try not to blink for a few seconds. This ensures the images are distortion-free.
If the doctor uses ultrasound, do not close your eyes after administering the anesthetic to ensure the drops are distributed evenly. You can drive immediately after this contactless procedure.
With the use of anesthetic, mild discomfort should completely subside within ten minutes.
When are the results ready and how do we interpret them?
A modern device instantly displays digital values on a computer monitor. Your doctor immediately analyzes the test results. The specialist will consider:
- Age
- History
- Other test results
General information
What does a keratopachymetry result show?
The numbers reflect the density of the transparent layer of the eye at the central and peripheral points. The doctor doesn't simply look at the values; they compare them with the established physiological norm.
Corneal Thickness in Micrometers: Why is it Important?
The generally accepted unit of measurement for this structure is micrometers. The normal thickness of the cornea in the very center is approximately 500-550 units. The doctor always evaluates these micrometers taking into account the patient's individual anatomy.
When the result requires a doctor's attention?
Any deviation from the norm may indicate hidden edema or tissue degeneration. In such situations, the ophthalmologist immediately prescribes additional tests. It is strongly recommended not to interpret the numbers in the report independently.
