To determine the effectiveness of the ARTISAN Aphakia Lens in individuals whose eye condition requires an anterior chamber lens to provide the focusing power previously accomplished by their natural lens.
Implantation of the ARTISAN® Aphakia Lens may be indicated in the following conditions:
1. Patients who are 22 years old or older at the time of the baseline visit of either sex and of any race who have a visually significant cataract (if preoperative phakic eyes) or IOL replacement surgery (in preoperative aphakic of pseudophakic eyes), subluxated capsule, weakened zonules or otherwise compromised capsular bag prohibiting implantation of a standard posterior chamber IOL such as in Marfan’s syndrome, ecotpia lentis or other pathology.
2. Patient must agree to comply with the visit schedule and other requirements of the study.
FELLOW EYE IMPLANTATION of patients will be allowed following stabilization of the first eye. Although the second eye will be under the same study inclusion/exclusion criteria and follow-up requirements as the first eye, data from the second eye will not contribute to the cohort population or the primary analysis. The following are criteria for fellow eye implantation:
1. A minimum of one week and a maximum of 6 months following the initial implant.
2. No adverse events of sight-threatening complications caused by the lens in the initial eye.
The physician should determine whether any of the following circumstances may create an undue risk when considering implanting an ARTISAN® Aphakia Lens. Investigators considering implantation in such patients should explore the use of alternative methods of correction and consider lens implantation only if alternatives are judged not to meet the needs of the patient:
1. Patients that are not able to meet the extensive postoperative evaluation requirements
2. Mentally retarded patients
3. When the patient has no useful vision or vision potential in the fellow eye
4. History of corneal disease (e.g., herpes simplex, herpes zoster keratitis, etc.), corneal dystrophy, degeneration, opacities or abnormalities that may affect vision.
5. Abnormality of the iris or ocular structure which would preclude fixation, such as aniridia, hemiiridectomy, severe iris atrophy, rubeosis iridis, or other compromising iris pathology
6. Patients with an anterior chamber depth less than 3.2mm. In case of aphakia or pseudophakia, measure the distance from the endothelium (corneal apex) to the iris plane.
7. Patients with uncontrolled glaucoma
8. High preoperative intraocular pressure( >25 mmHg)
9. Chronic, recurrent or active uveitis or history of the same
10. Pre-existing macular pathology that may complicate the ability to assess the benefit or lack of benefit obtained by the lens
11. Patients with an active retinal detachment
12. Retinal disease that may limit the visual potential of the eye such as retinopathy of prematurity or Stargardt’s retinopathy
13. Optic nerve disease that may limit the visual potential of the eye
14. Uncontrolled Diabetes mellitus
15. Pregnant, lactating, or plans to become pregnant during the course of this study
