Filter by:Prospective, open label, single arm, First in Human (FIH) clinical study to assess safety and efficacy of the CorNeat Keratoprosthesis, a synthetic cornea, for the treatment of corneal blindness
To evaluate the safety and probable benefit of the KeraKlear Non-Penetrating Keratoprosthesis when implanted in an eye with corneal opacity that is at high risk of complications with PK.
The introduction of surgical robots in the OR revolutionized a number of specialties (i. e. urology, gynecology, digestive surgery). Robots are currently used in many situations and the list of appropriate indications is growing rapidly. There are many potential advantages of robotics in eye surgery such as increased precision and maneuverability, better ergonomics, improved patient access to surgeons and surgical training. As a result, robotics might improve patient care. The Da Vinci© robot has been used for 10 years in experimental conditions to suture corneal lacerations, to perform corneal grafts, to remove ocular foreign bodies, lens capsules and vitreous. The authors reported a lack of precision resulting from poor visualization and the absence of microsurgical instruments. These elements were considered to be hurdles to further clinical investigation. The new Da Vinci Si HD© robot has been available since 2009 at the IRCAD center and more recently in Strasbourg University Hospital. It provides greater magnification and better resolution of the operative field than the previous model. We performed since 2012 various ocular surface surgeries on porcine eyes at the IRCAD center. The aim of the present trial is to perform the same procedures (amniotic membrane transplantations, pterygium surgeries, corneal grafts) in a clinical setting with the Da Vinci Si HD© system.
The purpose of this study is to determine if a new procedure, called laser-assisted lamellar anterior keratoplasty (LALAK), can achieve the same level of vision with a lower risk of potential complications after surgery compared to another corneal transplant procedure. The current procedure is called Intralase-enabled keratoplasty (IEK) and replaces the entire cornea. The LALAK procedure involves transplanting only the top layers of the cornea instead of the entire cornea. Only one eye will have this experimental procedure performed. If both eyes need to have surgery your doctor will help you decide on the best non-study option for your other eye.
The primary goal of the trial is to determine if laser-assisted lamellar anterior keratoplasty (LALAK) will reduce the risks of post-operative complications such as adhesions, glaucoma and cataract that are associated with pediatric penetrating keratoplasty (PK).
