Choosing the Right Procedure

The following table indicates which procedures are used to correct specific refractive errors. The range of diopter values for each procedure is listed in the following overview. For detailed information, please click on the individual procedure.

Corneal procedures / Laser	Nearsightedness	Farsightedness	Astigmatism
LASIK	up to -10 dpt.	up to +3 dpt.	yes
