Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Status post bilateral cataract or refractive lens surgery (with or without LRI) and implantation of Tecnis™ Multifocal IOL or Crystalens™ HD 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
* 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)
