Active clinical trials for "Cataract"

This study is a prospective, open-label clinical study of the VERITAS Vision System. The study will be conducted at up to three sites, with minimum 55 eyes and up to 150 eyes to be treated. The investigator or designee will perform the cataract surgery with the VERITAS Vision System on the subjects. The data from the system log files, the questionnaire, the operative report and other medical records will be used to assess the clinical utilization of the VERITAS Vision System.

This study will be a prospective, multicenter, bilateral, comparative, three-way masked (Sponsor, subject and evaluator), randomized clinical investigation conducted at up to 15 sites. Up to 300 subjects will be enrolled to achieve approximately 270 bilaterally implanted subjects, resulting in approximately 244 evaluable subjects (122 per lens group) at 6 months. After informed consent is obtained and confirmation that all eligibility criteria are met, the eye(s) may be treated according to randomization. After signing the informed consent form, subjects meeting all eligibility criteria will be randomized in a masked fashion to a treatment group: either the investigational IOL Model ZFR00V or the control IOL Model ZCB00. Prior to randomization, the investigator will choose which eye to operate on first for each subject at his/her discretion based on his/her standard clinical practice (e.g., the eye with the worse cataract, poorer best corrected distance vision and/or more severe optical/visual complaints). All subjects are intended to have bilateral cataract surgery with the second eye surgery occurring after the 1-week postoperative exam for the first eye, but no more than 30 days after the first eye surgery. All subjects will be examined through 6 months postoperatively according to the visit schedule

The purpose of this study is to evaluate the intra-examiner repeatability and inter-examiner reproducibility in lens zonule length measurements using very high-frequency (VHF) digital ultrasound (ArcScan Insight 100).

The purpose of this study is to report the incidence and related risk factors glaucoma following cataract surgery (GFCS). and to provide evidence-based evidence for the development of standardized follow-up methods or diagnosis and treatment decisions.

Purpose: To compare two pediatric cataract surgery procedures: intraocular lens (IOL) optic capture without anterior vitrectomy (AV) and in-the-bag IOL implantation with AV. Setting: Ege University Medical School Hospital, Izmir, Turkey. Design: Prospective randomized control clinical trial. Methods: Patients were randomly assigned to two groups: optic capture without AV (Group 1) or in-the-bag implantation with AV (Group 2). The following variables were compared: visual acuity, intraocular pressure, refractive errors, IOL tilt and decentration, lenticular astigmatism, anterior-posterior synechia, inflammatory cell deposits on IOL and post-operative complications.

In pediatric/congenital cataract surgery; multiple surgical interventions are performed, which needs multiple general anesthesias. Here, we describe a new technique, to end the operation in one session.

The purpose of this research is to assess the rotational stability of the AcrySof IQ Vivity Extended Vision Toric IOL and Refractive Visual outcome.

Short and long-term analysis of the refraction correction and optical image quality of modern premium intraocular lenses (IOLs) with the establishment of a database for quality assurance and optimization the computation constants of the lens power.

Multicentric, retro- / prospective, open-label, observational PMCF study to investigate visual performance, contrast sensitivity and patient satisfaction after mono- or bilateral implantation of Isopure 1.2.3. intraocular lenses following cataract surgery. The study treatment itself is not part of this observational clinical investigation. Only patients that already have been implanted with the device under investigation qualify for this retro- prospective observational clinical study.

To evaluate the differences between three-Dimensional heads-Up surgery system and traditional surgery methods of cataract surgery
