Clinical Evaluation of Fitting Investigational Contact Lenses

24. maj 2018 opdateret af: Johnson & Johnson Vision Care, Inc.
This study is a non-randomized, open label, bilateral, non- dispensing clinical trial with only one visit. The Eye Care Providers will be provided with a fitting guide and will determine the initial study lens selection. Each subject will wear either the investigational contact lenses or marketed contact lenses for approximately 30-90 minutes. This study aims to evaluate the ECPs impression of the fitting guide for a novel multifocal lens and also their success in fitting the lenses.

  3. Healthy adult males or females that are at least 40 years of age and no more than 70 years of age.
  4. The subject must either be wearing a presbyopic contact lens correction (e.g., reading spectacles over contact lenses, multifocal or monovision contact lenses, etc.) or if not respond positively to at least one symptom on the "Presbyopic Symptoms Questionnaire".
  5. The subject is a current soft spherical or toric contact lens wearer (defined as a minimum of 6 hours of wear per day at least two days of the week for a minimum of 1 month prior to the study).
  6. The subject's distance spherical equivalent or spherical component (if fit with a toric lens) of their refraction must be in the range -1.25 D to -3.75 D in each eye.
  7. The subject's refractive cylinder must be 0.00 D to -1.50 D in at least one eye and no greater than -1.50 D in either eye.
  8. The subject's refractive cylinder axis must be 90°±30° or 180°±30° in each eye.
  9. The subject's ADD power must be in the range of +0.75 D to +2.50 D in each eye.
  10. The subject must have best corrected visual acuity of 20/20-3 or better in each eye.
  11. The subject must have a wearable pair of spectacles if required for their distance vision.

Exclusion Criteria:

  1. Ocular or systemic allergies or disease, or use of medication which might interfere with contact lens wear.

  3. Currently diagnosed with diabetes.
  4. Infectious diseases (e.g. hepatitis, tuberculosis) or an immune-suppressive disease (e.g. HIV).
  5. Clinically significant (Grade 3 or 4) corneal edema, corneal vascularization, corneal staining, tarsal abnormalities or bulbar injection, or any other corneal or ocular abnormalities which would contraindicate contact lens wear.
  6. Entropion, ectropion, extrusions, chalazia, recurrent styes, dry eye, glaucoma, history of recurrent corneal erosions.
  7. Any previous, or planned, ocular or intraocular surgery (e.g., radial keratotomy, PRK, LASIK, lid procedures, cataract surgery, retinal surgery, etc.).
  8. A history of amblyopia, strabismus or binocular vision abnormality.
  9. Any ocular infection or inflammation.
  10. Any ocular abnormality that may interfere with contact lens wear.
  11. Use of any ocular medication, with the exception of rewetting drops.

Intervention / Behandling
Eksperimentel: etafilcon A Toric Multifocal
Subjects who are habitual contact lens wearers with Presbyopic correction or Presbyopic symptoms, at least 40 years of age and no more than 70 years of age, will be fitted, according to the fitting guides, with either the Multifocal Contact Lens or an Toric Multifocal Contact Lens if refractive cylinder power of the eye is between -1.00 to -1.50. The Intervention is approximately 30-90 minutes of wear time during a 1-day visit.

Tidsramme
The Average Number of Fitting Modifications to Optimize Vision
Tidsramme: 15 minutes post lens insertion
The eye care practitioner (ECP) followed the fitting guides to assess the vision provided by the study lenses and determined if a lens change (modification) was needed. The ECP modified the lenses based upon the subject's responses in accordance with the fitting guide. Up to two modifications per subject was allowed. The number of modifications required by the ECP to optimize vision was reported.
