Active clinical trials for "Cataract"

Retrospective/Prospective Study on Visual Performance of a Monofocal Intraocular Lens (IOL). The objective is to compare best corrected distance visual acuity (CDVA) between 1-3-month and 12- month follow-up.

The objective is to evaluate refractive stability (spherical equivalent change ≤ 0.50D from 1-month to 3-months).

The aim of this study is to determine the principal factors that influence endothelial cell loss three month post cataract surgery. Methods: Multi center observational Cohort study, inclusion period from 12/01/2022 to 10/06/2022. One hundred and seventy-five eyes of hundred and four patients who have appointment for cataract surgical indication were included. The percentage of corneal endothelial cell loss was quantified using specular microscopy before and 3 months after the surgery. 14 variables (pre-operative and intra-operative) that could be associated to endothelial cell injury were selected. A bivariate analysis of relationship between these factors and endothelial cell loss at 3 months was performed by simple linear regression (Wilcoxon and Fischer tests). Multivariate analysis was performed by multiple linear regression in order to identify the factors independently related to endothelial cell loss.

This will be a single arm, open-label, prospective study of patient-reported outcomes of patients with bilateral implantation of the Panoptix or Panoptix Toric implant.

This study investigate the change of the corneal endothelial cells in patients with type 2 diabetes after phacoemulsification with intraocular lens implantation.

The principal objective of the study is to determine the visual acuity at far, intermediate and near distances tested with optotypes at different distances from the eyes and tested with defocus addition lenses of patients implanted bilaterally with the POD 26P AY FineVision. Secondary objective will be to test the glare and contrast sensitivity.

The purpose of this study is to assess the axial IOL rotation after surgery with an MC 6125 AS IOL. At the end of surgery the orientation of the IOL is documented with a short video clip via the operating microscope unit. Follow-up examinations are performed 1 hour, 1 week and 6 months after surgery. Rotational stability of the IOL is assessed using retroillumination images with a method to avoid bias from cyclorotation or head tilt.

Refractive outcome after cataract surgery mainly depends on the prediction of the intraocular lens that is implanted in the eye during surgery. Aim of this study is to measure the position of the lens capsule during surgery and to use this measurements to improve post-operative refractive outcomes.

The management of childhood glaucoma (CG), childhood cataract (CC) and other birth defects affecting the eyes requires frequent hospital attendances and often multiple surgical and medical interventions, and are often associated with poor vision. Chronic medical conditions and vision impairment can affect quality of life (QoL). The QoL of children with the above conditions has not previously been evaluated.

Congenital cataracts (CC) are the leading cause of childhood visual disabilities and treatable childhood blindness worldwide1. CC patients have a wide range of presentations of lens opacities and are generally categorized into several groups based on the etiologies, anatomical positions, or shapes of lens opacities. Cataractous eyes of CC patients are also frequently complicated with other anterior segment abnormalities due to their close anatomical relationships and similar developmental origins. Lens opacities in different positions may be related to specific anterior segment abnormalities; for example, anterior polar cataracts are associated with greater corneal astigmatism (CA). However, no studies have systematically related the position of lens opacities to specific anterior segment abnormities, mainly due to the small number of CC patients, a lack of proper equipment, and a lack of awareness of these important relationships.
