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

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 ...

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 ...

Phase N/A

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 ...

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.

Phase N/A

Tranexamic Acid To Reduce Bleeding in Patients Treated With New Oral Anticoagulants Undergoing Dental Extraction

Interventional phase IV, randomized, double-blind, placebo-controlled trial: Feasibility: a 3-day regimen of tranexamic acid mouthwash in patients treated with direct oral anticoagulants Efficacy: reduction of bleeding events after tooth extraction compared to placebo Safety: any non-oral bleeding or thrombo-embolic events


The Impact of Immediate Implant Placement on Alveolar Ridge Preservation Techniques

Hypothesis/Aims Primary hypotesis Placing an immediate implant into a fresh extraction site plus a bone substitute filling and a matrix covering could negatively modify the healing patterns and thus the tissue morphology of the ridge site with regard to: clinical hard tissues dimensions (bone width and height, bone volume) clinical ...

Phase N/A

A Clinical Assessment of the Full Range of Functional Vision With Three Tecnis Multifocal IOL 1-Piece Models in Bilateral Cataract Extraction

This will be a multi-center, parallel comparison clinical study design with two treatment groups. One hundred (100) qualified study patients will receive a +2.75D (ZKB00) Tecnis Multifocal 1-Piece IOL in their dominant eye. Of these study patients, 50 patients will receive the +3.25D (ZLB00) Tecnis Multifocal 1-Piece IOL in their ...
