入选标准

  • •Patients must be scheduled to undergo primary intraocular lens implantation for the correction of aphakia following extraction of a senile cataract.
  • •Patients must have a cataract causing reduction in visual acuity to a level of 20/40 or worse with BAT on medium setting.
  • •Patients must require Synchrony® Lens correction of 16D - 28D or, if participating in the control study, patients must require a Clariflex® (AMO®), Phacoflex® II models SI30NB (AMO®) or a SI40NB (AMO®).
  • •Patients must have ≤ 1.0 D of preoperative keratometric astigmatism.
  • •Patients must have clear intraocular media other than cataract(s).
  • •Patients must be age 50 or older at the time of implantation.
  • •Patient must be willing and able to return for all scheduled follow-up examinations and have signed a written informed consent form.

排除标准

  • •Patients with any anterior segment pathology (anterior segment or corneal abnormalities, chronic uveitis, iritis, corneal dystrophy, pseudoexfoliation, etc.).
  • •Patients with glaucoma, glaucoma suspect or ocular hypertension, i.e., IOP > 22 mmHg.
  • •Patients with previous retinal detachment or retinal pathology including age- related macular degeneration.
  • •Patients with diabetes, currently being treated systemically.
  • •Patients with systemic or ocular disease that may prevent the patient from achieving uncorrected distance visual acuity of 20/32 or better post operatively.
  • •Patients with congenital bilateral cataract.
  • •Patients who require chronic administration of any topical ophthalmic or systemic medication that may affect accommodation such as mydriatic, cycloplegic and myotic agents; tricyclic antidepressants, phenothiazines, benzodiazepines, first generation antihistamines, anticholinergic agents. The use of tamsulosin hydrochloride (Flomax®) is also excluded preoperatively due to floppy iris syndrome.
  • •Patients with best corrected visual acuity of 20/80 or worse in the fellow eye not attributable to cataract.
  • •Patients who are currently participating or have participated in an investigational study, other than this study, within the past 60 days.
  • •Patients who have had previous ocular surgery in the operative eye, including refractive surgery.
