Clinical Investigation of the Modified Rayner Monofocal Aspheric 600C (With Axis Marks) Intraocular Lens

Inclusion Criteria: * Male or female aged ≥21 years of age. * Cataract for which phacoemulsification extraction and posterior IOL implantation has been planned for the operative eye. * Best corrected distance visual acuity (BCDVA) projected to be better than 20/30 (+0.18 logMAR) in the operative eye after cataract removal and IOL implantation. * Calculated IOL power requirement within the range +8.0 to +34.0D * If present, subject must have corneal astigmatism of \<1.50 D in the operative eye. * Expected dilated pupil size ≥ 5.0 mm in diameter to visualise the axis markings * Subject must provide written informed consent. * Subject must be able to return for scheduled follow-up examinations for 24 months after surgery. Exclusion Criteria: * History of ocular trauma or prior ocular surgery in the operative eye. * Microphthalmia * Corneal decompensation or endothelial insufficiency * Pseudo exfoliation * Pars planitis * Subjects with diagnosed degenerative visual disorders in the operative eye (e.g.,macular degeneration or other retinal disorders) that are predicted to cause future visual acuity losses to a level of 20/30 (+0.18 logMAR) or worse. * Inability to achieve secure placement in the designated location e.g. absence of a secure peripheral anterior capsule, zonule laxity or dehiscence; posterior synechiae to the capsular bag * Active ocular disease in the operative eye, e.g., clinically significant dystrophy, chronic severe uveitis, proliferative diabetic retinopathy, or chronic glaucoma. * Concurrent participation in another drug or device investigation. * Patients who are expected to require retinal laser treatment. * Females who are pregnant, nursing or plan to become pregnant during the study.
