Filter by:The Artisan lens (Artisan Aphakic, Ophtec BV) is an iris- claw lens designed for implantation in children with insufficient capsular support. In spite of less surgical manipulations and a relatively shorter operation time, the procedure carries the risk of corneal endothelial cell loss or dis-enclavation, particularly in children. However, most of the studies that studied iris-claw lenses in aphakic children were retrospective evaluated only a single technique; either anterior or retropupillary fixation, or comparable to other techniques of fixation. Thus the aim of this work is to prospectively compare the 2 techniques of iris-claw lens implantation and their effects on central endothelial cell density, the anatomical and visual outcome, as well as the complications' rate.
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.
To perform a retrospective investigation of the CT Lucia 601 IOL implantation in the sulcus
To compare the accuracy of four lens diameter measurement methods and to study the influencing factors of intraocular lens deviation after operation
The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
To study the efficacy of an ocular bandage contact lens for the treatment of dry eye after complicated and combined cataract surgery
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.
In this work, we evaluated the biometry data of lens subluxation inducing acute angle closure which were misdiagnosed as primary angle closure at the first visit, and compared with the data of chronic angle closure glaucoma, cataract, primary acute angle closure.
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.
