Interventions

Group 1: With optical coherence tomography (OCT), the center of the lens capsule is preoperatively determined. Postoperatively, the measurement is repeated and the position of the intraocular lens is

Exclusion criteria

Exclusion criteria: • Previous corneal procedures or intraocular procedures • Pronounced (> 5 Dpt.)

Design outcomes

Primary

MeasureTime frame
• Correlation of the preoperatively measured capsule bag equatorial position (center of the capsule bag) with the postoperative position of the intraocular lens (center point of the IOL). • Comparison between capsule and forehead depth measurements Data collection using optical coherence tomography

Secondary

MeasureTime frame
• Determination of corrected and uncorrected visual acuity (refraction) pre- and postoperatively, with Standard method (projector). • Descriptive analysis of patients who can not be measured with the OCT
