Active clinical trials for "Refractive Errors"

Pediatric eye patients receive infrared photoscreener screening and skiascopy as a part of routine examination to compare ability to detect amblyopia risk factors.

The aim of this prospective study is to evaluate the clinical performance of habitual wearers of methafilcon A toric lenses after a refit with fanfilcon A toric lenses for 1-month of daily wear.

The aim of this work is to investigate the clinical performance and subjective acceptance of the comfilcon A asphere contact lens when compared to single-vision spectacles in subjects who have never worn contact lenses and who use digital devices (such as phones, tablets, laptops, desktop computers) for at least 4 hours per day on at least 5 days per week.

The clinical investigation objective is to evaluate safety and performance outcomes of trifocal IOL implantation to improve vision in patients with cataract and/or ametropia (hyperopia, myopia) and/or presbyopia. Retrospective data from preoperative status up to 12 month postoperative status will be collected from patients that were implanted with Medicontur's 640PM intraocular lens: Preoperative status: Preoperative Screening and Baseline Surgery: IOL implantation M1: 1 month +/- 2 weeks postoperative follow-up M3: 3 months +/- 1 month postoperative follow-up M12: 12 months +/- 3 months postoperative follow-up

LASIK is a refractive surgery technique widely used in France. Postoperatively, the classic treatment after LASIK consists of instilling drops to reduce dry eyes. REPADROP® is an innovative eye drops stimulating corneal innervation. To date no study has quantified the improvement in dry eye syndrome and thus the quality of life of patients using REPADROP®.

In this study, you will wear an invesetigational contact lens, Apioc-P or Apioc-PT, the way you wear your current contact lenses for approximately one month (no more than 35 days).

The primary objective of the study is to demonstrate that the lubricity of DAILIES TOTAL1® (DT1) lenses after 16 hours of wear is equivalent to the lubricity of unworn DT1 lenses.

The purpose of this study is to compare the subjective performance of two daily disposable contact lenses with respect to comfort and handling.

The purpose of the study is to investigate the corneal epithelial cell response associated with lens wear that results in solution-induced corneal staining (Phase1) and to determine the cell appearance in symptomatic and asymptomatic contact lens wearers (Phase 2).

The purpose of this study was to evaluate overall satisfaction with AIR OPTIX® COLORS as compared to FRESHLOOK® COLORBLENDS contact lenses.
