Secondary Outcome Measures:
  • Use of spectacle correction and vision-related quality of life [ Time Frame: 3 months postoperatively ]

Enrollment: 26
Study Start Date: December 2010
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Tecnis Multifocal IOL
    Presbyopia correcting IOL
    Device: crystalens Accommodating IOL
    Presbyopia correcting IOL

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 18 years of age or older
  • Status post bilateral cataract or refractive lens surgery (with or without LRI) and implantation of Tecnis™ Multifocal IOL or Crystalens™ AO Accommodating IOL
  • Best-corrected ETDRS equivalent visual acuity of 20/30 or better in each eye
  • Naturally dilated pupil size (in dim light) > 3.5 mm (with no dilation medications) for both eyes
  • Clear intraocular media (no posterior capsular opacification, or status post YAG capsulotomy)
  • Availability, willingness, and sufficient cognitive awareness to comply with examination procedures

Exclusion Criteria:

  • Ocular disease which could potentially limit uncorrected visual acuity or visual performance.
  • Use of systemic or ocular medications that may affect visual outcomes
  • Acute or chronic disease or illness that would increase risk or confound study results (e.g. diabetes mellitus, immunocompromised, etc.)
  • Uncontrolled systemic or ocular disease
  • History of ocular trauma
  • History of ocular surgery other than that required for inclusion in this study
  • 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 worse than 20/30
  • 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 or abnormally shaped pupils)
