Comparison of Postoperative Visual Acuity and Spectacle Independence Between the Tecnis Multifocal Intraoculer Lens (IOL) and the Crystalens Accommodating IOL

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)
