Filter by:This is a monocentric retrospective, open-label clinical study in patients after unilateral or bilateral implantation of hydrophobic acrylic monofocal toric intraocular lens PODEYE TORIC and executed only with standard of care examinations. The investigational device is CE approved. The investigational device and all study products, including the devices used for the study examinations, have been used within the intended use specifications from the manufacturer. In addition, there were no invasive or other burdening examinations. The investigator is an accredited and experienced cataract surgeon and researcher. The primary endpoint is to determine rotational stability in a minimum of 120 eyes of patients with PODEYE TORIC IOL implantation after cataract surgery. Patients will be enrolled for the documentation and evaluation of retrospective data up to 6 months postoperatively.
This is an observational, prospective follow-up post-marketing study of CE marked medical devices aimed at treating astigmatism in patients with cataracts. The main objective is to evaluate the response of the intrastromal arcuate incisions procedure for the correction of low corneal astigmatism with the Catalys femtosecond laser using the Cassini Ambient equipment with iris registration in cataract surgery.
The purpose of this study to evaluate the overall performance of PRECISION1™ for Astigmatism contact lenses with MyDay® Toric contact lenses.
This study aimed to compare the clinical performance of two daily disposable toric contact lenses.
This is a single-center, prospective PMCF study whereby patients undergoing routine cataract surgery will have monolateral implantation of hydrophilic monofocal toric intraocular lens Ankoris.
we aimed to analyze the effects of cataract surgery using a 1.8-mm steep-axis clear corneal incision (CCI) on the posterior corneal surfaces based on the keratometry from the rotating Scheimpflug imaging device (Pentacam HR) in candidates for toric intraocular lens (IOL) implantation
The purpose of this study is to compare the clinical performance of PRECISION1™ for Astigmatism (P1fA) contact lenses with 1-DAY ACUVUE MOIST® for ASTIGMATISM (AMfA) contact lenses.
To evaluate patient reported outcomes associated with quality of vision before and after treatment with Contoura Vision Topography-Guided LASIK.
This study is a 6-month, prospective, multicenter, randomized (1:1:1), subject-masked and evaluator-masked, bilateral clinical investigation of the TECNIS IOL Models C1V000 and C2V000 versus the TECNIS Eyhance™ Model ICB00 IOL. The study will be conducted at up to 15 sites in EU, AU, NZ and/or AP and will enroll up to 225 subjects to achieve approximately 67 bilaterally implanted subjects in each lens group. Allowing for 10% lost-to-follow-up, this will achieve approximately 60 evaluable subjects in each lens group at 1, 3, and 6 months. The eye implanted first will be considered the primary (monocular) study eye.
The primary objective of this PMCF investigation is to systematically collect safety and effectiveness data with the VISUMAX 800 laser in clinical daily routine SMILE use for the purpose of post market surveillance.
