The newly developed wavefront sensor technology, specifically for the intraoperative use, by our engineers in Germany, is characterized by high reliability and accuracy.
Patented Flying-Spot technology
In contrast to the classical systems of the Hartmann-Shack and the Tscherning method, this new sequential method recently has not the well known risks of "overlappings" and "cross over".
Measurements of the phakic, aphakic and pseudophakic eyes
Where the dynamic range of Shack-Hartmann sensor technology is limited to the area -10.00 to 8.00 diopters, the new generation covers with a dynamic range of -20 to +20 diopters the requirements from the intraoperative use. The new "flying spot" technology achieves high reliability and accuracy in a wide dynamic range of 32 diopters.
Virtual cylinder - axis marking
The manual marking of the cylinder with a sterile pen or axis marker always carries the risk that the ink runs on the conjunctiva or bleaches intraoperatively that the orientation of the toric lens is impossible at the marks.
Eyetracker and video-overlay systems use reference points on the pupil, blood vessels in the conjunctiva or manual marks. Intraoperative mydriasis, bleeding or a small image section affect the reliability of the axis marking for IOL implantation.
Reliability of the virtual axis marking by intraoperative aberrometry only requires transparency of the dioptric apparatus. Intraoperative measurement excludes a confusion of preoperative obtained patient data.
