Clinical Trial Summary

In order to determine the intraocular lens to be implanted during cataract surgery, keratometry and axial length must be measured in preoperative. The axial length is obtained by ocular ultrasound mode B. Keratometry is obtained by means of an automatic refractometer or corneal topography. Currently, ultrasound scanners are being developed with a topography module to combine axial length and keratometry measurement. The investigators want to evaluate the corneal topography module of the Zeiss® IOL Master 700 biometer.

Outcome
Type Measure Description Time frame Safety issue
Primary keratometry measurements to show that the keratometry measurements obtained using the topography module integrated in the IOL Master 700 are consistent with those obtained by a standard topography in patients operated for cataract surgery. The measures will be: K1 (steepest corneal meridian), K2 (flattest corneal meridian), Kmax (central corneal keratometry), the unit of measurement is the diopter. day 1
