A Clinical Trial to Evaluate the Safety & Effectiveness of the Raindrop

Status Terminated

Clinical Trial 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. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D with no more than 0.75 D of refractive cylinder. The Raindrop Near Vision Inlay will be implanted in the non-dominant eye.

Clinical Trial Description

Presbyopia is 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 suffer limitations from the patient perspective. For example, reading glasses can easily be lost or not conveniently available. Multifocal contact lenses suffer from visual symptoms and instability due to potential rotation and movement of the contact lenses on the surface of the cornea. And, successful monovision is generally limited to patients with a history of successful use of contact lenses for monovision, and even in these eyes, monovision is associated with a substantial decrease in stereo acuity and contrast sensitivity.

ReVision Optics has developed the Raindrop Near Vision Inlay for the correction of near and intermediate vision. 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 Raindrop Near Vision Inlay is expected to provide low induction of visual symptoms and improvement of near and intermediate vision in emmetropic subjects with presbyopia. This technology may also demonstrate potential clinical utility in bilateral pseudophakic subjects. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
