Before surgery, of course, the eye must be thoroughly examined organically. In addition, the eye is measured in order to calculate the refractive power of the lens, that is to be used. These include measurement of the corneal radii, the total refractive power of the eye, examination of visual acuity, axial length measurement, etc.
To optimize the overall result, further investigations are possible and useful.
Example from our current standard:
For the LASICAT treatment further investigations are added to allow a personalized reduction of corneal astigmatism (see also Cataract surgery / LASICAT).
