Treatment of Presbyopia
The objective of this study is to evaluate the safety and effectiveness of the PresbyLens corneal inlay to be implanted in subjects with presbyopia for the improvement of near vision. The ReVision Optics corneal inlay is a 2.0mm, 30 micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require a +1.50 to +2.50 of reading add. Subjects must have a manifest refraction spherical equivalent of -0.50 to +1.00D with no more than 0.75 of refractive cylinder. Subjects must have had no previous refractive surgery in the eye to be implanted. The PresbyLens will be implanted in the non-dominant eye

Detailed Description:
The loss of near vision and the ability to perform tasks that require near vision is part of the normal aging process. This natural transformation in the eye occurs as a result of the loss of accommodation of the crystalline lens, a condition known as presbyopia. Presbyopia, characterized by a progressive, age-related loss of accommodation (i.e., the lens ability to focus clearly over a wide range of distances), is most prevalent of all visual deficiencies, affecting 100% of the population over the course of a normal life span. Loss of accommodation begins early in life and, for an emmetropic eye, generally culminates in a complete loss of functional near vision.
ReVision Optics has developed the PresbyLens for the correction of near vision. The PresbyLens is a 2mm corneal inlay, as small as a pinhead, thinner than a human hair and about 1/500th of a droplet of water. The inlay is the same refractive index as the human cornea. The inlay is placed in the non-dominant eye,centered over the pupil after a corneal flap (LASIK)has been made. The PresbyLens is expected to provide presbyopic subjects with improvement of near and intermediate vision.
Eligibility| Ages Eligible for Study: | 35 Years to 65 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | Yes |
| Sampling Method: | Probability Sample |
Presbyopic subjects needing from +1.50 to +2.50D of reading add will be enrolled. Subjects must have a manifest refraction spherical equivalent of -0.50 to +1.00D with no more that 0.75D of refractive cylinder. The inlay will be implanted in the non-domnant eye. Bilateral implants of this device are not allowed.
Inclusion Criteria:
must be presbyopic adults, needing from +1.50 to +2.50 or reading add must have uncorrected near visual acuity worse than 20/40 and better than 20/200in the eye to be implanted must have an uncorrected distance visual acuity of 20/25 or better in both eyes must have a distance visual acuity correctable to 20/20 in both eyes must have a near visual acuity correctable to 20/20 in both eyes must have a manifest refraction spherical equivalent between -0.50 and +1.00D in the eye to be implanted with no more than 0.75D of refractive cylinder must report stable vision, i.e. no change in distance vision and or MRSE within 0.50D over prior 12 months must discontinue hard or rigid gas permeable lenses for at least 3 weeks and discontinue soft lenses for at least 1 week prior to baseline examination must have a minimum central corneal thickness of >500 microns in the eye to be implanted must have a mesopic pupil < 7.0mm and photopic pupil >3.0mm in the eye to be implanted subjects aged 45 years or younger must have an endothelial cell count
Exclusion Criteria:
Subjects with a difference of >0.75 between the manifest refraction spherical equivalent and the cycloplegic refraction spherical equivalent Subjects with anterior segment pathology, including clinically significant cataracts, in the non-dominant eye Subjects with residual, recurrent, active ocular or uncontrolled eyelid disease, or any corneal abnormality (including endothelial dystrophy, guttata, recurrent corneal erosion, etc.) in the non-dominant eye Subjects with ophthalmoscopic signs of keratoconus (or keratoconus suspect) in the non-dominant eye Subjects with clinically significant dry eyes, as determined by either the presence of greater than mild symptoms of dryness or discomfort or SPK greater than grade 1 Subjects with distorted or unclear mires on topography maps of the non-dominant eye Subjects with macular degeneration, retinal detachment, or any other fundus pathology that would prevent an acceptable visual outcome in the non-dominant eye Subjects who have undergone LASIK surgery in the non-dominant eye Subjects with a history of herpes zoster or herpes simplex keratitis Subjects who have a history of steroid responsive rise in intraocular pressure, pre-operative IOP>21 mm Hg, glaucoma or are a glaucoma suspect Subjects with a history of diagnosed diabetes, autoimmune disease, connective tissue disease, or clinically significant atopic syndrome Subjects on chronic systemic corticosteroids or other immunosuppressive therapy that may affect wound healing, and any immunocompromised subjects Subjects who are using ophthalmic mediation(s) other than artificial tears for treatment of any ocular pathology Subjects using systemic medications with significant ocular side effects Subjects who are pregnant, lactating, or planning to become pregnant during the course of the study Subjects what are participating in any other ophthalmic drug or device studies during the time of this clinical investigation Subjects with known sensitivity to planned study concomitant medications
