Active clinical trials for "Lens Subluxation"

This is a single-centre, observational cohort study with the following objectives: Firstly, the investigators aim to evaluate the vision-related quality of life and mental health status in congenital ectopia lentis patients. Secondly, the investigators target to investigate the correlations between genotype and clinical phenotype in patients of congenital ectopia lentis. Thirdly, to explore the metabolic profiles in the aqueous humor (AH) of patients with congenital ectopia lentis. Lastly, this study aims to explore the longitudinal changes of ocular biological parameters and complications in patients with postoperative congenital ectopia lens in the Chinese population.

To analyze the postoperative visual effects, and to compare the safety and efficacy of different surgical treatment with of Marfan Syndrome with subluxation lens.

The purpose of this study is to report the intraoperative performance and postoperative outcomes of the Cionni-modified capsule tension ring implantation in eyes with subluxated lenses.

Overall aim of the study is to compare the safety and efficacy of two different surgical methods to treat Late In-the-bag intraocular lens dislocation.

To perform a retrospective investigation of the CT Lucia 601 IOL implantation in the sulcus

To compare the safety and efficacy of a new multi-functional cataract-assisted surgical instrument with that of traditional cataract-assisted surgical instrument in cataract surgery with subluxation of lens.

To study the efficacy of an ocular bandage contact lens for the treatment of dry eye after complicated and combined cataract surgery

The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.

A prospective randomized study on patients with late in the bag intraocular lens (IOL) dislocation, after cataract surgery. To obtain normal visual function, these patients needs surgery. In this study the investigators will look for advantages and dis-advantages after two different surgical approaches to late in-the-bag IOL dislocation.

To report the Ultrasound Biomicroscopic findings following Cionni Ring bag fixation and in-the-bag IOL Implantation. To assess the relationship of the Bag and Cionni ring positioning in relation to surrounding ocular structures, in pediatric eyes
