Clinical trials

To analyze the difference between measured total corneal astigmatism and actual corneal astigmatism under different region modes and optimize the region setting.

This study evaluates the safety and efficacy of a viscoelastic-free method for Implantable Collamer Lens(ICL) implantation to treat high myopia. The subjects undergo randomization of ICL implantation using the viscoelastic-free method on one eye and undergoing standard method on the other one. The post-operative data are collected for analysis.

Comparison of Postoperative Outcomes in Patients with High Myopia Undergoing Cataract Surgery Implanted with Extended Depth of Focus Intraocular Lens (ICB00) and Monofocal Intraocular Lens (ZCB00)

Double-dose statin regimen achieves merely 6% of decrease in low-density lipoprotein cholesterol (LDL-C) levels, whereas the risk of side effects increased largely. The investigators' previous pilot study (NCT01686451) has suggested that red yeast rice was of similar lipid-lowering efficacy while was associated with less fatigue than statins. The purpose of this study is to evaluate the efficacy and safety of combined therapy with red yeast rice and low-dose atorvastatin in persons with mild atherosclerotic cardiovascular disease and who qualified for statin therapy according to national guidelines.

The aim of this study is to figure out whether anesthesia type have an influence on the prognosis of hip fracture surgery.30-day mortality and morbidity after the surgery are our main observational index,and according to literature and our experience,regional anesthesia may have a better prognosis after hip fracture surgery compared with general anesthesia.

The purpose of this study is to compare and evaluate the clinical outcomes of 6 kinds of Multifocal Intraocular Lenses: SN6AD1, SBL-3, LS-313 MF30, AT LISA tri 839 MP, ART, LS-313 MF30T.
