A SCAN IMMERSION MODE FOR BEST ACCURACY :

---

It is a tool to measure IOL Power for implantations during cataract surgery.

It first measures the axial length of the eye then calculates IOL Power with keratometry readings.

     We have immersion mode A-Scan which prevents corneal indentations (which usually occurs in routine A-Scan machines causing error) & hence giving a more accurate reading. Immersion mode is now standard technique to achieve emetwsia
