NCT04775849

Brief Summary

The investigational device is an approved femtosecond laser (FSL) device with an integrated imaging system to perform certain steps of the cataract procedure. The FSL will perform anterior capsulotomy and lens fragmentation in individuals suffering from age-related cataract with need of cataract surgery. The laser will be reduced to image the Berger space. If not visible, the space will be enhanced with BSS and Volon A to visualize the BS. Cataract surgery will be performed in subjects who have signed an informed consent form. Macula thickness will be measured with Spectralis OCT on screening date. Postoperative examinations will be implemented in accordance with the approved investigational plan on subjects and includes: visual acuity, slitlamp examination and retinal oct imaging.

Outcome Measures

Primary Outcomes (1)

  • The primary objective is a Berger Space larger than 400μm

    The number of patients with visible Berger space and the capacity (volume) of the visible Berger Space will be determined by using the intraoperative OCT recording

    intraoperative

Secondary Outcomes (2)

  • Difference of central macular thickness between time points

    Baseline to 1day, 1 week, 3 weeks

  • Intraocular pressure in different timepoints

    Baseline to 1day, 1 week, 3 weeks

Study Arms (1)

Intraoperative Berger Space Imaging

EXPERIMENTAL

Intraoperative OCT imaging of the space between the posterior capsule and the anterior hyaloid

Device: Femtosecond Laser

Interventions

Femtosecond Laser assisted Cataract Surgery will be performed uni- or bilateral

Intraoperative Berger Space Imaging
