Changes in Prostaglandin Levels in Laser Cataract Surgery (LCS) Subject to Laser Prevalence

Intraindividual Comparison of Prostaglandin E2 (PGE2) and Total-prostaglandin (PG) Following Femtosecond Laser-assisted Cataract Surgery Using a Low-energy, High-frequency Femtosecond Laser-Device in Regard to the Sequence of Anterior Capsulotomy and Lens Fragmentation

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.

Cataract surgery will be performed in subjects who have signed an informed consent form. Aqueous humor will be collected and screening will be performed for Total Prostaglandin and Prostaglandin E2 via en-bloc Enzyme-linked Immunosorbent Assay (ELISA)-Kit.

Exclusion Criteria:

• Preceding ocular surgery or trauma
