A-Scan Test in Bellandur, Bangalore – Nelivigi Eye Hospital
A-Scan, also known as Amplitude Scan, is an essential ultrasound-based diagnostic test used to measure the internal structures of the eye. At Nelivigi Eye Hospital, Bellandur, we use advanced A-Scan technology to ensure precise eye measurements for cataract surgery planning, IOL power calculation, and the evaluation of several eye conditions.
As a NABH-accredited centre equipped with modern diagnostic systems, our A-Scan testing ensures accuracy, comfort, and reliable results for every patient.
What Is an A-Scan?
A-Scan is a non-invasive ultrasound test that helps measure:
- Axial length of the eye
- Lens thickness
- Corneal and internal structural distances
- Characteristics required for IOL (Intraocular Lens) power calculation
How Is A-Scan Conducted?
The procedure is performed using a high-frequency ultrasound probe that gently touches the surface of the eye or hovers close to it (depending on the method).
The device sends sound waves into the eye and measures the echo to calculate internal dimensions.
These measurements help the doctor plan surgeries with accuracy and make diagnostic evaluations more precise.
Is A-Scan Painful?
No.
A-Scan is completely painless and safe. It is a non-surgical procedure, and patients usually feel no discomfort as:
- Numbing drops may be used
- The test lasts only a few minutes
- No injections or cuts are involved
Why Is A-Scan Important for Ophthalmologists?
A-Scan provides critical measurements that help your eye specialist:
- Calculate the exact IOL power needed for cataract surgery
- Detect and evaluate various internal eye abnormalities
- Plan post-operative outcomes with greater precision
- Understand axial length differences in conditions like high myopia
- Monitor structural changes in certain eye diseases
When Is A-Scan Recommended?
Your ophthalmologist may suggest A-Scan if you:
- Are preparing for cataract surgery
- Have high refractive errors
- Show signs of abnormal eye growth
- Need IOL power calculation
- Require detailed internal eye measurement for diagnosis
