Release of Proinflammatory Cytokines (IL-1β, IL-6) and Total-prostaglandin (PG) Following Femtosecond Laser-assisted Cataract Surgery Compared to Manual Cataract Surgery

Intraindividual Comparison of Proinflammatory Cytokines (IL-1β, IL-6) and Total-prostaglandin (PG) Following Femtosecond Laser-assisted Cataract Surgery Using a Low-energy, High-frequency Femtosecond Laser-Device Compared to Manual Cataract Surgery

Patients with bilateral age related cataract will be included in the study. Manual cataract surgery (MCS) will be performed in one eye and laser cataract surgery (LCS) in the corresponding eye. LCS will be performed with an approved femtosecond laser (FSL) device with an integrated imaging system.

After surgery aqueous humour will be collected and screened with Enzyme-linked Immunosorbent Assay (ELISA) Kits for Interleukin-1β; Interleukin-6 and PG.

Inclusion Criteria:

• Bilateral age-related cataract necessitating phacoemulsification extraction and posterior intraocular lens implantation.
• Pupil dilation of ≥ 6.5mm
• Age 40 and older

Exclusion Criteria:

• Corneal abnormality
• Pseudoexfoliation
• Preceding ocular surgery or trauma
• Uncontrolled glaucoma
• Proliferative diabetic retinopathy
• Iris neovascularization
• History of uveitis/iritis
• Microphthalmus
• Recurrent intraocular inflammation of unknown etiology
• Blind fellow eye
• Uncontrolled systemic or ocular disease
• Pregnancy
• Lactation
