The flattening effect of a corneal incision may depend on whether it has been performed on the right or the left eye. [J Refract Surg. 2016;32(9):598-603.].

The CorT based on total corneal power measurements corresponds better, both in variability and closeness, with manifest refractive cylinder than the CorT based on anterior corneal power measurements. This total CorT would be fundamental when planning toric intraocular lenses or limbal relaxing incisions or other corneal astigmatic surgery.
