Phase 4
Completed
- Conditions
- Aphakia
- Registration Number
- NCT01061281
- Lead Sponsor
- Innovative Medical
- Brief Summary
The purpose of this study is to compare the visual outcomes with bilateral implantation of Tecnis MF and Crystalens™ AO Aberration-free Accommodating intraocular lens (IOLs) 6 months after post cataract surgery.

- Target Recruitment
- 40
Inclusion Criteria
- Age 18 or greater
- Bilateral cataracts for which phacoemulsification extraction and posterior IOL implantation has been planned for both eyes
- Visual potential of 20/25 or better in each eye after cataract removal and IOL implantation
- Preoperative best-corrected distance visual acuity (BCDVA) worse than 20/40 Snellen
- Naturally dilated pupil size (in dim light) > 4.0 mm (with no dilation medications) for both eyes
- Preoperative corneal astigmatism of 1.0 D or less
- Clear intraocular media other than cataract
- Availability, willingness, and sufficient cognitive awareness to comply with examination procedures
Exclusion Criteria
- Use of systemic or ocular medications that may affect vision
- Acute or chronic disease or illness that would increase risk or confound study results (e.g. diabetes mellitus, immunocompromised, etc.)
- Subjects with diabetes mellitus
- Uncontrolled systemic or ocular disease
- History of ocular trauma or prior ocular surgery
- Amblyopia or strabismus
- Known pathology that may affect visual acuity; particularly retinal changes that affect vision (macular degeneration, cystoid macular edema, proliferative diabetic retinopathy, etc.)
- Diagnosed degenerative visual disorders (e.g. macular degeneration, or other retinal disorders) that are predicted to cause future acuity losses to a level of 20/30 or worse
- Subjects who may be expected to require retinal laser treatment or other surgical intervention
- Capsule or zonular abnormalities that may affect postoperative centration or tilt of the lens (e.g. pseudoexfoliation syndrome)
- Pupil abnormalities (non-reactive, tonic pupils, abnormally shaped pupils, or pupils that do not dilate at least 4.0 mm under mesopic/scotopic conditions)
- Contact lens usage within 6 months for PMMA contacts lenses, 1 month for gas permeable lenses or 1 week for extended-wear and daily-wear soft contact lenses
- Requiring an intraocular lens < 15.0 or > 26.0 diopters
