NCT01352442

Brief Summary

The purpose of this study is to determine if the AcuFocus Corneal Inlay ACI 7000PDT will provide an effective method of for the correction of presbyopia in patients who have normal distance vision but need correction such as glasses or contact lenses to see clearly at near.

Eligibility Criteria

Age45 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects must sign and be given a copy of the written Informed Consent form.
  • Subjects must be emmetropes needing a magnitude of +1.00D to +2.50D of reading add.
  • Subjects must have distance corrected near visual acuity worse than 20/40 and better than 20/100 in the eye to be implanted.
  • Subjects must have distance visual acuity correctable to at least 20/20 in both eyes.
  • Subjects must have a preoperative spherical equivalent of plano defined as Plano to -0.75D with no more than 0.75D of refractive cylinder as determined by cycloplegic refraction in the eye to be implanted.
  • Subjects must have a stable refraction twelve months prior to ACI implantation: i.e. MRSE within 0.50D over prior twelve months as determined by subject history.
  • Subjects who are soft contact lens wearers must discontinue their contact lenses for at least one week prior to ACI pre-operative examination.
  • Subjects must have a minimum central corneal thickness of ≥ 500 microns in the eye to be implanted.
  • Subjects must have a corneal power of ≥ 41.00D and ≤ 47.00D in all meridians in the eye to be implanted.
  • Subjects must be ≥ 45 years and ≤ 60 years of age at the time of subject eligibility visit.
  • Subjects must have an endothelial cell count ≥ 2000 cells/mm2 in the eye to be implanted.
  • Subjects must be willing and able to return for scheduled follow-up examinations for 12 months after surgery.
  • Subjects must demonstrate tolerance to monovision blur in the eye to be implanted as determined by loose lens blur tolerance or monovision contact lens trial.

You may not qualify if:

  • Subjects with a difference of \>1.00D between the spherical equivalent manifest refraction and the spherical equivalent cycloplegic refraction.
  • Subjects with anterior segment pathology, including cataracts, in the eye to be implanted.
  • Subjects with residual, recurrent, active ocular or uncontrolled eyelid disease, or any corneal abnormality (including endothelial dystrophy, guttata, recurrent corneal erosion, etc.) in the eye to be implanted.
  • Subjects with ophthalmoscopic or topographic signs of keratoconus (or keratoconus suspect) or keratoectasia in the eye to be implanted.
  • Subjects with dry eye as determined by objective testing; anesthetized Schirmer's test result \<10 mm or a tear break-up time (TBUT) less than 10 seconds are excluded.
  • Subjects with distorted or unclear corneal mires on topography maps of the eye to be implanted.
  • Subjects with macular degeneration, retinal detachment, or any other fundus pathology that would prevent an acceptable visual outcome in the eye to be implanted.
  • Subjects who have worn RGP or PMMA contact lenses within the last 6 months.
  • Subjects who have undergone previous intraocular or corneal surgery, including PRK, LASIK, CK, LASEK, and cataract surgery in the eye to be implanted.
  • Subjects with a history of herpes zoster or herpes simplex keratitis.
  • Subjects who have a history of steroid-responsive rise in intraocular pressure, preoperative IOP \> 21 mmHg, glaucoma, ocular hypertension, or are glaucoma suspects.
  • Subjects with an abnormal threshold visual field.
  • Subjects with a history of diagnosed diabetes, diagnosed 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 medication(s) other than artificial tears for treatment of any ocular pathology including ocular allergy.
