Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Intraoperative Berger Space Imaging
Arm Description
Intraoperative OCT imaging of the space between the posterior capsule and the anterior hyaloid
Outcomes
Primary Outcome Measures
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
Secondary Outcome Measures
Difference of central macular thickness between time points
Difference in Central Macular Thickness (CMT) with time.
Intraocular pressure in different timepoints
Intraocular pressure changes with time.

5. Study Description
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.
