Observation of Rotation of an Intraocular Lens

Observation of Rotation of the MC 6125 AS Intraocular Lens

The purpose of this study is to assess the axial IOL rotation after surgery with an MC 6125 AS IOL.

At the end of surgery the orientation of the IOL is documented with a short video clip via the operating microscope unit. Follow-up examinations are performed 1 hour, 1 week and 6 months after surgery. Rotational stability of the IOL is assessed using retroillumination images with a method to avoid bias from cyclorotation or head tilt.

Inclusion Criteria:

• Uni or bilateral age-related cataract necessitating phacoemulsification extraction and posterior IOL implantation

Exclusion Criteria:

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