The purpose of this study is to investigate the efficacy and safety of the Ahmed valve implant (AVI) and the Molteno single-plate implant (MSPI) in eyes with refractory glaucoma during a follow-up period of 24 months.
The purpose of this study is to compare the safety and efficacy of the Ahmed Valve and the Baerveldt Tube in treating refractory glaucoma. Eligible patients will be recruited from multiple study centers and randomized to a glaucoma drainage device for implantation. They will be followed long-term based upon outcome measures including intraocular pressure, glaucoma medication use, visual acuity, complications of the surgery and further treatments required.
This study will determine the effectiveness of Mitomycin-C use in the glaucoma surgery Ahmed valve implantation. Approximately 100 patients will be enrolled, with half receiving the Mitomycin-C treatment and the other half receiving placebo treatment.
The objective of this study is to compare the long-term safety and efficacy of the Ahmed and the Baerveldt implants in patients who are undergoing aqueous shunt implant surgery for glaucoma. Eligible patients will be randomized. Outcome measures include intraocular pressure, visual acuity, visual field, number of glaucoma medications, glaucoma reoperations, and complications, including suprachoroidal hemorrhage, endophthalmitis, choroidal effusion, diplopia, corneal edema, and...
This triple-blind, stratified, randomized clinical trial includes 100 eyes of 100 patients aged 18 to 85 years with refractory glaucoma. Eligible subjects undergo stratified block randomization; eyes are first stratified to one of four subgroups: group 1:patients with previous failed trabeculectomy, group 2: uveitic glaucoma, group 3: neovascular glaucoma and group 4: other indications like aphakic glaucoma or glaucoma associated with vitreoretinal procedures. In each su...
The management of neovascular glaucoma (NVG) is a challenge for the ophthalmologist and surgery is frequently needed to control IOP. The success rates of a drainage device is usually lower in NVG than in other forms of glaucoma. Triamcinolone intra-vitreous injections acetate has been used to treat macular edema secondary to diabetic retinopathy and central retinal vein occlusion and also to control inflammation in ophthalmologic surgeries. In the present study we will c...
The purpose of this study is to evaluate survival and success rates of dental implants placed with immediate loading protocol in extraction sockets. All patients were monitored for 1 year after implants placement.
Outcomes of subjects with uncontrolled glaucoma with a single existing aqueous tube shunt implant undergoing a second aqueous shunt to transscleral diode laser cyclophotocoagulation.
In the management of open angle glaucoma, frequently more then one procedure is necessary to control the intra ocular pressure. There is still no consensus whether this second intervention should be a second trabeculectomy or a shunt device. In the present study we compare a second trabeculectomy versus Ahmed silicone shunt device in open angle glaucoma patients with previous trabeculectomy without proper IOP control.
This is a prospective, open, single arm, multi-center clinical study in China. The primary objective of this study is to demonstrate the safety and effectiveness of the PERCEVAL S heart valve when used to replace a diseased native or malfunctioning prosthetic aortic valve in the indicated Chinese population for tissue heart valve replacement and suitable to the PERCEVAL S valve. The secondary objectives are to collect all relevant device and subject demographics, procedu...
The purpose of the study is to provide evidence of safety and effectiveness of the study valve. The rationale is to offer a replacement mitral valve for patients with anatomy that is too small for the currently commercially available valves ranging in size from 16mm to 37mm.
To assess the therapeutic effect of hinged 8-figure plate by comparing with the traditional 8-figure plate through a randomized controlled clinical trial by assessing the differences between preoperative and postoperative data. The hypothesis is that the hinged 8 plate provides low complications that this treatment is as good as the traditional one.
Comparison of Ahmed Glaucoma Implant (AGI) against trabeculectomy with mitomycin C in patients with uncontrolled open angle glaucoma
This is a study to evaluate immediate implants.
The surgical treatment of wrist fractures (distal radius bone) has been changed by the introduction of a new plate design, the locking plate. This results in improved fixation and stabilisation of the fracture fragments allowing early movement. This type of plate has been increasingly used throughout the world but questions have been raised regarding the potential complications of the surgery, particularly nerve and tendon injury. The Norfolk and Norwich Hospital has treated ...
This study evaluates the use of short dental implants to support mandibular overdenture together with the use of laser therapy for treatment of patients with atrophic ridges. All participants will receive laser therapy; half of participants will receive two short implants and the other half will receive four short implants.
The purpose of this study is to determine the efficacy and safety of tubularized incised plate urethroplasty versus foreskin graft tubularized incised plate urethroplasty in primary hypospadias. This study only included patients with width of urethral plate ≤ 7 mm, width of glans ≤ 14 mm, and urethral plate depth shallow o moderate.
Reconstruction of the aortic valve using the tri-leaflet repair technique is non-inferior with regard to effective orifice area (EOA) to surgical aortic valve replacement (SAVR) with a biological prosthesis (St. Jude Trifecta GT) as gold- standard.
Immediate tooth replacement with implants into extraction sockets has become a common clinical procedure regarding implant survival, osseointegration and esthetics. Basically, when there is a labial bone plate loss after extraction 2 stage GBR procedure would be carried out to allow adequate amount of bone formation to be reconstructed and receive the dental implant. The challenge is when there is a partial or complete loss of labial plate of bone resulting from severe ...
A prospective single arm study evaluating feasibility and safety of a catheter-based transapical implantation of the Ventor Embracer™ aortic valve bioprosthesis in patients with severe aortic valve disease, specifically aortic stenosis, who are at elevated risk for standard surgical valve replacement.
Glaucoma drainage devices are usually placed in the superior quadrants. The superotemporal quadrant is usually the site of choice. However, when the upper fornix is scarred and especially when conjunctiva is two fibrotic to enable adequate coverage of tube with a scleral or other patch graft, some surgeons place the tube in one of inferior quadrants.
The study is a prospective randomized longitudinal clinical study to compare pre-adapted patient-specific orbital implants utilizing an office-based 3-D printer versus standard non-adapted orbital implants (the latter being the traditional approach and current standard of care).
Randomised within subjects cross-over study (n=94) exploring the cognitive and physiological processes associated with portion control. Participants will eat a self-served lunch using a portion control plate vs. a conventional (control) plate on two separate occasions under a controlled laboratory environment. Portion size, meal micro-structure, attention, memory and satiety markers will be analysed. The portion control plate is a prototype designed in collaboration with the co...
The anterior-inferior clavicle plate position will have a lower rate of soft tissue irritation that limits activity and/or requires hardware removal compared to superior plate position.
Until now it has not been investigated whether placement of implants in SS patients is less successful than compared to non-SS patients. The risk factors and the efficacy of dental implants in dry mouth patients are not known because of the lack of scientific evidence. The aim of this study is to investigate changes in marginal peri-implant bone loss and the clinical performance of dental implants in SS patients compared to implants in healthy patients.
