This study will be a prospective, multicenter clinical trial in which a total of 400 subjects will be enrolled. All subjects will be followed over a 36 month time frame with a maximum of 15 clinical sites participating. Qualified subjects will provide informed consent for entry into the study.
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 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 (LASIK)has been made. The Raindrop is expected to provide presbyopic subjects with improvement of near and intermediate vision.

Number of Participants With Improvement in Uncorrected Near Visual Acuity (20/40 or Better) in the Implanted Eye
75% of participants should achieve uncorrected near visual acuity in the implanted eye of 20/40 or better as compared to preoperative baseline
Time frame: 24 Months
Number of Participants With no or Minimal Loss of Best Corrected Visual Acuity in the Implanted Eye
Less than 5% of participants should lose more than two lines of best corrected distance and near visual acuity in the implanted eye; and less than 1% of participants with preoperative best spectacle corrected visual acuity (BCDVA) of 20/20 in the implanted eye should have best corrected distance and near visual acuity worse than 20/40 in the implanted eye at 6 months postoperative and all subsequent visits.
Time frame: at 6 months postoperative and all subsequent visits
Number of Participants With Induced Manifest Refractive Astigmatism in the Implanted Eye
Less than 5% of participants should have postoperative manifest refractive astigmatism in the implanted eye that increases from baseline by greater than 2.00 D at 6 months postoperative and all subsequent visits.
Time frame: At 6 months postoperative and all subsequent visits
