hen 1 mm error in measurement means a possible 3 D difference in the patient‘s refraction, accuracy is top priority. QUANTEL MEDICAL’ s new ultrasound biometer, the AXIS II, provides accuracy and more :

● AXIS II can store all the data obtained for up to 20 patients in its internal memory. The echograms can be reviewed and the I.O.L. calculations done at your convenience that evening, the following day... ● The results may be printed out with a choice of format or downloaded to your computer as preferred.

● The A scan echogram is made up of 1 500 points which is 3 times more than a standard biometry and gives you 3 times more accuracy. ● AXIS II gives you the possibility to zoom and reposition the markers in the presence of pathology which may have affected the readings. ● All the difficult-to-measure eyes are catered for : dense cataract, long eyes, pseudo-phakic eyes assuming the specific speeds for PMMA, acrylic and silicone lenses. And the sound speeds may be varied by the user to cater for new materials. ● Acquisition can be made using the contact method, probe handheld or fixed on the tonometer holder. But also using the immersion method, to insure no corneal compression and guarantee measurement along the optical axis .

Biometry probe with extension handle (optional).

● You can input the information on up to 40 lenses that you use regularly (or not so regularly) to have it at your finger-tips. ● All the latest formulae are included - and you can compare the results of one with the other, which is particularly useful for longer and shorter eyes. ● The Haigis formula uses three constants for even greater accuracy. The user is offered the possibility to optimize his constants at the following website : http://www.augenklinik.uni-wuerzburg.de. This service requires a password.
