Overview
Brief Summary
A cataract is the clouding of the natural lens in the eye and is very common as when getting older. A cloudy lens makes it difficult to see. A cataract is treated by removing the cloudy lens and replacing it with an intraocular lens (known as an IOL). The goal of this clinical trial is to determine if the Eyedeal® IOL can be safely implanted in a subject's eye and if it can replace efficiently the natural lens.
Subjects will be asked to attend a total of seven visits for this study for a period of 12 months after surgery.
Detailed Description
To investigate the safety and performance of the Eyedeal® PX65AS1 intraocular lens (IOL) * To evaluate the safety profile with regards to best-corrected visual acuity, and adverse events * To evaluate the performance with regards of best corrected distance VA after the device implantation The Eyedeal® IOL (PX65AS1) is a foldable single-piece ultra-violet absorbing posterior chamber intraocular lens (IOL). It is an optical implant to replace the human crystalline lens in the visual correction of aphakia in adult patients after cataract removal. The Eyedeal® PX65AS1 IOL lens is made of a high refractive index soft cross-linked polyolefin. The Eyedeal® PX65AS1 IOL lens has an aspheric optic with symmetric optic design and spherical neutral and correct lens's own spherical aberration supporting haptics to provide proper position of the IOL optic within the capsule.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Adults (22 years of age or older at the time of surgery) of any gender and race, diagnosed with age related cataracts in one eye.
- •Preoperative best corrected distance visual acuity (BCDVA) of 20/32 or worse.
- •Projected postoperative BCDVA 0.20 logMAR or better in the study eye, as determined by Investigator's medical judgment.
- •Calculated spherical power targeted at emmetropia at distance in the study eye.
- •Calculated lens power within the available range for the Eyedeal® Model PX65AS1 IOL (+0.50D - +34.00D).
- •Planned cataract removal by phacoemulsification procedure.
- •Clear intraocular media other than cataract, in the study eye.
- •Pharmacologically dilated pupil size of at least 6.0mm.
- •2.0 D or less of preoperative astigmatism in the study eye.
- •Willing and able to complete all required postoperative visits.
Exclusion Criteria
- •Any type of cataract (e.g., traumatic, congenital, polar) other than those noted in inclusion criteria.
- •Ocular conditions which could affect the stability of the IOL (e.g., pseudoexfoliation, zonular dialysis, evident zonular weakness or dehiscence, etc.) in the study eye.
- •Any anterior segment pathology likely to increase the risk of complications from phacoemulsification cataract extraction (e.g., chronic uveitis, iritis, iridocyclitis, aniridia, rubeosis iridis, clinically significant corneal disorders, (Fuch's, or anterior basement membrane dystrophy, etc.) in the study eye.
- •Mature cataract that is likely to prolong phacoemulsification and/or lead to intraoperative complications prior to attempted IOL implantation.
- •Any visually significant intraocular media opacity other than cataract in the study eye.
- •History of any clinically significant retinal pathology or ocular diagnosis (e.g., diabetic retinopathy, ischemic disease, macular degeneration, retinal detachment, amblyopia, optic neuropathy, microphthalmos, aniridia, neuro-ophthalmic disease, fixation problems etc.) in the study eye that could alter or limit final postoperative visual prognosis.
- •History of any intraocular, retinal, corneal or refractive surgery in the study eye (including LASIK, PRK, LRI, etc.).
- •History of cystoid macular edema in the study eye.
- •History of serious corneal disease (e.g., herpes simplex, herpes zoster keratitis, etc.) in either eye.
- •Severe dry eye that, in the opinion of the investigator, would impair the ability to obtain reliable study measurements.
Outcomes
Primary Outcomes

SAFETY OUTCOME MEASURE - Best Corrected Visual Acuity
Time Frame: 12 months
The safety of the Eyedeal® Model PX65AS1 IOLs (Xi'an Eyedeal Medical Technology Co., Ltd.) will be measured by the following criteria: Loss of BCDVA measured in accordance with ISO 11979-7:2018-Appendix E
SAFETY OUTCOME MEASURE - Evaluation of Patient record
Time Frame: 12 months
