Influence of an Capsular Tension Ring on the Rotation of an Intraocular Lens (Aspira®-aA Also Known as MC 6125 AS)

Influence of an Capsular Tension Ring on the Rotation of an Intraocular Lens (Aspira®-aA Also Known as MC 6125 AS)

The purpose of this study is to observe the axial IOL rotation after surgery with a capsular tension ring (CTR) and a MC6125 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
