Clinical Trial of the Femtosecond Laser System VisuMax for Refractive Correction of Hyperopia by Means of Lenticule Extraction

This is a feasibility and clinical evaluation study of the VisuMax femtosecond laser for refractive correction of hyperopia using the small incision lenticule extraction (ReLEx smile) method. In ReLEx the VisuMax femtosecond laser creates two interfaces that define a refractive lenticule of stromal tissue. In ReLEx FLEx, the upper interface ...

The Impact of a Known Bioactive Agent on the Resolution of Alveolar Socket Preservation

The current pilot research project explores the addition of a known Bioactive Agent: Platelet Derived Growth Factor (PDGF) into the completed "socket graft" to test its impact on healing responses. Histomorphometric and qualitative assessments will be utilized on microscopic slide material derived from cores trephined as the initial step in ...

A Clinical Study on the Efficacy and Safety of Lando Absorbable Collagen Membrane in Oral Bone Repair

This is a randomized, paralleled, control trial to validate the effectiveness and safety of Lando absorbable collagen membrane for oral bone repair.

Phase N/A

A 14 Weeks Longitudinal Study to Investigate the Effect of Leukocyte- Platelet Rich Fibrin Plug on the Quality of the Newly Formed Bone in Ridge Preservation Procedure Following a Tooth Extraction. It is a Clinical Radiographic and Histomorphometric Study.

This 14 weeks longitudinal study will be conducted from March 2018 to June 2020, with a 40 participants. No subjects will receive placebo medication at any point in the research procedures. The proposed sample population will be recruited from the patient population of the University of Kentucky College of Dentistry ...

Intra-operative Feed Back on Traction Force During Vacuum Extraction: Safe Vacuum Extraction Alliance

The most common indications for vacuum extraction are dystocia and/or fetal asphyxia. The safety of assisted vaginal delivery with vacuum extraction has been discussed since its introduction almost fifty years ago. Serious complications such as asphyxia, intracranial hemorrhage and seizures are overrepresented at vacuum extraction compared to spontaneous vaginal delivery. ...

Music Listening for Cataract Surgery

Cataract surgery is the most frequent surgical procedure performed in Europe, usually done under topical anaesthesia. Restlessness and hypertension are the most frequent medical complications during surgery, potentially leading to surgical complications. Since the surgery is ambulatory and requires the patient's cooperation, heavy intravenous sedation should be avoided. However, this ...

VisuMax Femtosecond Laser Small Incision Lenticule Extraction for the Correction of High Myopia

Laser refractive surgery (LASIK and PRK) has been established for 25 years to treat myopia (short-sightedness). Over this time, the technology has been significantly improved to enable safe treatment of myopia up to -15D. Improvements including changing the shape of the lens of corneal tissue removed to better match the ...

Phase N/A

Is the Direct Inferior Alveolar Nerve Block Required for Third Lower Molar Extraction?

The objective is to compare the anesthetic efficacy of an infiltrative anesthetic technique placed buccally between the first and second mandibular molars plus infiltration of the third molar's lingual mucosa with the direct inferior alveolar nerve block plus buccal nerve block for the extraction of lower wisdom teeth. All using ...

Phase N/A

A Study Comparing Two Monofocal Aspheric Hydrophobic Acrylic Intraocular Lenses: the Alcon CLAREON and the Abbott Medical Optics PCB00

This is a bilateral randomised controlled study to compare visual performance, refractive outcome, forward light scatter, patient satisfaction and objective measurement of glistenings following insertion of two monofocal, aspheric, hydrophobic acrylic intraocular lenses (IOLs). A new product is compared with an established one.

Evaluation of a Device That Separates Blood Cells From Serum/Plasma

A new blood collection tube has recently been developed; the tube separates serum/plasma from the whole blood while the blood flows into the tube. This is accomplished by a filter set inside the tube; the filter set may be impregnated with an anti coagulant agent, such as sodium citrate (blue ...
