Summary

This Study determines the most precise method for measuring post-operative refraction following implantation of the asymmetric multifocal LS-313 MF30 comparing the results of Refraction of the different Autorefractor Keratometers with the subjective measurements for distance and near.

Detailed description

This is a post market study without invasive interventions. The patients have been treated with cataract surgery and MIOL Implantation at least 3 months ago. They will be invited for only one follow up visit to measure the postoperative refraction with different Autorefractor-Keratometers, a Manual Refractometer, the test device "iTrace" and with determination of the subjective refraction for distance and near with the appropriate corrections at the Department of Ophthalmology in Neubrandenburg, Germany.

Conditions
