Pachymetry
Precise Corneal Measurement
Our hospital is equipped with a Pachymeter, an essential device for measuring corneal thickness. This non-invasive tool utilizes ultrasound technology to provide our ophthalmologists with accurate and reliable measurements.
Knowing the exact thickness of the cornea is critical for diagnosing conditions like Glaucoma, managing corneal swelling (edema), and determining if a patient is a suitable candidate for refractive surgeries like LASIK.
Why is Pachymetry Important?
1. Glaucoma Assessment
Eye pressure (IOP) measurements can be influenced by corneal thickness. A thin cornea may lead to underestimation of pressure, while a thick cornea may lead to overestimation. Pachymetry allows us to correct these readings for an accurate diagnosis.
2. Refractive Surgery (LASIK/ICL)
Surgeries like LASIK involve reshaping the cornea. It is vital to ensure sufficient corneal thickness remains after surgery to maintain the eye's structural integrity. Patients with thin corneas may be advised alternative procedures like Trans-PRK or ICL.
3. Corneal Disease Management
It helps in monitoring conditions that cause the cornea to swell with fluid, such as Fuch's Dystrophy or post-surgical edema.
Common Questions about Pachymetry
No. The test is quick and painless. We use numbing eye drops before touching the cornea with the ultrasound probe. The entire process takes only a minute for both eyes.
The measurement itself takes only a few seconds per eye. Including preparation, the entire procedure is usually completed within 5-10 minutes.
Yes. Pachymetry does not require pupil dilation, so your vision will remain normal, and you can drive home immediately after the test.
