Brief Summary:
The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision.

Condition or disease Intervention/treatment Phase
Presbyopia Pseudophakia Device: Raindrop Near Vision Inlay Phase 3

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.

Presbyopia is also a natural outcome of pseudophakic subjects with monofocal or toric intraocular lenses. Treatment of pseudophakic presbyopia generally consists of reading glasses, contact lenses, or monovision LASIK which allows the patient to see near objects. All these options present limitations from the patient perspective.

ReVision Optics has developed the Raindrop corneal inlay for the correction of near vision. The Raindrop 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 or corneal pocket has been made. The Raindrop is expected to provide pseudophakic presbyopic subjects with improvement of near and intermediate vision.

Arm Intervention/treatment
Experimental: Raindrop
A single arm study to evaluate the effectiveness of a 2mm Raindrop Near Vision Inlay for the treatment of presbyopia in pseudophakic subjects. This corneal inlay is placed under a LASIK flap or in a corneal pocket, and is designed to change the anterior curvature of the cornea, resulting in the ability to reduce spectacle dependency for near and intermediate tasks.
Device: Raindrop Near Vision Inlay
To improve the near and intermediate vision in subjects who have previously undergone cataract surgery (pseudophakic subjects)

Primary Outcome Measures :
  1. Improvement in uncorrected near visual acuity [ Time Frame: 24 Months ]
    Seventy-five percent of eyes should achieve uncorrected near visual acuity of 20/40 or better.

  2. Preservation of best corrected visual acuity [ Time Frame: 24 Months ]
    Fewer than five percent of eyes should lose more than 2 lines of best corrected distance visual acuity after implantation

Secondary Outcome Measures :
  1. Improvement in uncorrected intermediate visual acuity [ Time Frame: 24 Months ]
    Seventy-five percent of eyes should achieve uncorrected intermediate visual acuity of 20/40 or better (measured at 80cm/32 inches)

  2. Adverse Events [ Time Frame: 24 Months ]
    Adverse events should occur in less than 10% of eyes and any single adverse event should occur in less than 2.5% of eyes.
