Orbscan™ and Ziemer Galilei™

Only approximately 5% of laser eye surgery providers like CorrectVision Laser Institute use  both Orbscan™ and Galilei™ that measures both front and back corneal surfaces. This gives a complete assessment of the cornea using Optical, Placido Disc, and Scheimpflug imaging technology. Many other laser eye surgery providers will only perform traditional corneal topography.

With traditional topography machines, typically only the front surface of the cornea is mapped. Orbscan™ and Galilei™ show both the front and back surfaces of the cornea. Orbscan™ and Galilei™  can detect changes in the back surface of the cornea, such as early corneal conditions like Keratoconus (a condition in which laser surgery is not advisable).   We have ability to evaluate the back surface of the cornea gives our surgeons the chance to better assess the cornea for surgical procedures, which can ultimately make treatment safer and more accurate by giving valuable information to our eye surgeon prior to any procedure.

These instruments also measure the thickness of the cornea. Unlike the ultrasound machines, which measure the thickness of the cornea only in the small area where the “probe” touches, Orbscan™ and Galilei™ measure the thickness in any part of the cornea.
