Precise & Accurate

A-Scan precision and accuracy, under both cataract and immersion mode, are ensured by MEDA's mature technology and professional expertise in ophthalmic field.


Automatic measurements for 4 different eye types:

Normal, Cataract, Aphakic and Special.

Manual measurement also available.


Up to 8 groups of readings automatically measured per each scan, with averaging and standard deviation for a higher level of reliability.


Touch screen and footswitch equipped

to enable smooth operations.

Accurate Results

Automatic reading at single or multiple points

for corneal thickness;

Multiple measurements at single point for higher reliability;

Higher accuracy enabled by averaging readings.
