Details and patient eligibility

About

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.
