Primary outcomePrimary: Mean Manifest Refraction Cylinder (MRCYL) for Eyes Implanted With HMTIOL — -0.50; -0.57 diopter

Summary

The purpose of this study was to evaluate the safety and effectiveness of the HARMONI® Modular Intraocular Lens System with a toric optic (HMTIOL) in subjects with pre-existing corneal astigmatism in need of cataract surgery.

Eligibility Criteria

Key Inclusion Criteria

  • Planned removal of visually significant bilateral cataract by manual phacoemulsification cataract extraction
  • Pre-existing corneal astigmatism in at least 1 eye of 0.75 to 2.50 diopter (D)
  • Target dioptric lens power within the range of 16 - 26 D
  • Willing to discontinue contact lens wear for the duration of the study
  • BCVA projected to be ≤0.2 logarithm minimum angle of resolution (LogMAR)
  • Stable cornea
  • Dilated pupil size at least 7.0 millimeters (mm)
  • Able to understand and provide informed consent.

Key Exclusion Criteria

  • History of any intraocular or corneal surgery in study eye (including refractive)
  • Pregnant or lactating
  • History of any clinically significant retinal pathology or ocular diagnosis in study eye that could alter or limit final postoperative visual prognosis
  • History of ocular conditions which could affect the stability of the IOL in study eye
  • Any anterior segment pathology likely to increase the risk of complications from phacoemulsification cataract extraction in study eye
  • Any visually significant intraocular media opacity other than cataract in study eye
  • Uncontrolled glaucoma in study eye
  • Uncontrolled systemic disease
  • Severe dry eye that would impair the ability to obtain reliable study measurements
  • Systemic medication that may confound the outcome or increase the intraoperative and postoperative risk to the subject.
