Ultrasound A-Scan
Precision Diagnostics with Ultrasound A-Scan
Our advanced eye hospital utilizes this non-invasive technology for precise eye diagnostics. By emitting sound waves, the A-scan provides essential data for accurate diagnoses and tailored treatment plans.
The A-scan is the gold standard for Biometry, which measures the length of the eye (axial length). This measurement is the most critical factor in calculating the power of the Intraocular Lens (IOL) to be implanted during cataract surgery.
Key Applications & Benefits
Why do we perform it?
- Cataract Surgery Planning: To calculate the precise power of the artificial lens (IOL).
- Diagnosing Eye Conditions: Helps in diagnosing masses or tumors within the eye.
- Monitoring Myopia: Tracking the elongation of the eyeball in progressive nearsightedness.
Patient Benefits
- Non-Invasive: Uses safe sound waves, no radiation.
- Quick: The test takes only a few minutes per eye.
- Painless: Causes no discomfort to the patient.
- High Accuracy: Ensures better visual outcomes after surgery.
Common Questions about A-Scan
It works like sonar. A probe sends sound waves into the eye, and the echoes reflect off the back of the eye. The device measures the time it takes for the echo to return to calculate the eye's length.
No special preparation is needed. If you wear contact lenses, you might be asked to remove them beforehand. The test is quick and you can drive home afterward.
Yes, ultrasound technology is extremely safe and has been used in medicine for decades. It does not involve any harmful radiation.
