入选标准

  • 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.

排除标准

  • 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.

结局指标

主要结局

Rotational Stability

时间窗: 180 Day

IOL rotation will be measured through retro-illumination photography between 0-3 hours post-operatively and this will be compared with images from Day 120-180 to determine degree of IOL rotation in accordance with ISO-11979-7:2014 requirements

Best Corrected Distance Visual Acuity (BCDVA)

时间窗: 180 Day
