Corneal Mapping
The Orbscan® anterior segment analysis system measures the shape of the cornea and allows the surgeon to determine if you are suitable for laser eye treatment and that your eyes are healing
Corneal Thickness
It is vital to check if your cornea is thick enough for Zyoptix. If you wear contact lenses, you may need to manage without them for up to 4 weeks (depending on the type of lenses), to eliminate any corneal swelling from the lenses and to make sure the surgeon can get an accurate measurement.
