Orbscan II™

Orbscan II™

Only approximately 5% of laser eye surgery providers like Correctvision Laser Institute use an Orbscan™ that measures both front and back corneal surfaces. This gives a complete assessment of the cornea. The other 95% of laser eye surgery providers will only perform traditional corneal topography.

Topography machines map only the front surface of the cornea. Unlike the topography machines showing only the front surface of the cornea, Orbscan™ shows both front and back surface of the cornea. Some early conditions of the cornea like Keratoconus (where laser surgery is not advisable) show changes in the back surface of the cornea, which is detected only by Orbscan™. The ability to evaluate the back surface of the cornea allows your surgeon to better assess your cornea for surgery. This is important for safety reasons. It also shows changes in the whole cornea after the surgery giving valuable information to the surgeon prior to an enhancement.

This instrument also measures 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™ measures thickness in any part of the cornea.
