简要总结
The objective of this study is to evaluate the safety and effectiveness of the investigational Omega Refractive Capsule (model VI)
详细描述
This study is a prospective, interventional, randomized, controlled, paired eye, subject-masked design.
Subjects will be randomly assigned to which eye will receive the Omega Refractive capsule VI with an FDA approved intraocular lens. Fellow eyes will serve as controls and receive an FDA approved IOL (no Omega capsule).

入选标准
- •40 years of age or older at the time of surgery diagnosed with bilateral cataracts
- •Able to understand and sign an informed consent
- •Willing and able to complete all study visits and assessments required for the study
- •Calculated lens power within the available range
- •Corrected distance visual acuity is equal to or worse than 20/40 in each eye with or without a glare source present
- •Bilateral cataracts eligible for extraction by phacoemulsification and capsular bag fixated IOL implantation
- •Potential postop visual acuity of 20/25 or better in the judgment of the surgeon
- •Preoperative corneal astigmatism of 4.0 D or less with normal corneal topography
- •Clear intraocular media other than cataract
- •Preop endothelial cell density of 2000 cells/mm2 or more
排除标准
- •Subject's best corrected vision is light perception or no light perception in either eye
- •Cataract opacification preventing adequate Binocular Indirect Ophthalmoscopic retinal and macular examination.
- •Orbital abnormalities, such as thyroid related orbitopathy, causing significant exophthalmos.
- •Eyelid abnormalities causing lagophthalmos.
- •Significant anterior blepharitis or meibomian gland dysfunction
- •Corneal abnormalities or conditions, other than regular topographic corneal astigmatism
- •Krukenburg's spindle (linear pigmentary deposits on the corneal endothelium)
- •Abnormalities of the iris including trans-illumination defects
- •Pupil abnormalities (abnormally shaped, fixed or non-reactive)
- •Pharmacologic dilation less than 7 mm
- •Axial length <22.5mm
- •Lens thickness <4.1 mm
- •Anterior chamber depth <2.5mm
- •Prior ocular surgery
- •Epiretinal membrane
- •Macular edema
- •Retinal tears including operculated holes
- •Amblyopia
- •Glaucoma of any kind
- •Pseudoexfoliation syndrome
- •History of uveitis/iritis
- •Diabetic retinopathy
- •Acute, chronic or uncontrolled systemic or ocular disease that may confound the results of the study (including rheumatologic conditions such as Rheumatoid arthritis, ankylosing spondyliltis, Sjögren's syndrome, and neurologic conditions such as optic neuritis or multiple sclerosis).
- •Prior or anticipated use of tamsulosin or silodosin (e.g., Flomax®, Flomaxtra®, Rapaflo®) or similar medications
- •Average Keratometry <38D or > 48D by topography
- •Any pathology of the zonules including evidence of zonular weakness, zonular instability, zonular damage, or coloboma effecting zonules.
- •History of ocular trauma
- •Pregnant, lactating, or has another condition with associated fluctuation of hormones that could lead to refractive changes
