Clinical trials

Glaucoma is a common and irreversible disease of the optic nerve. It is the second leading cause of blindness worldwide. Glaucoma can be treated with medication, laser therapy, or surgery; the latter is often necessary. Traditional surgeries are invasive and carry a high rate of complications (hypotony, endophthalmitis, cataracts, etc.). Consequently, several types of micro-invasive surgeries (MIGS) and less invasive but effective surgeries, LIGS, have been developed to reduce surgical risks while maintaining effectiveness in lowering intraocular pressure (IOP). PRESERFLO is a drainage system less than 1 mm thick that regulates the outflow of aqueous humor from the eye. It is made of a soft, flexible biomaterial that conforms to the curvature of the eye. This biomaterial does not trigger a negative immune response. PRESERFLO is an example of a recently developed, powerful LIGS procedure (with preliminary results demonstrating efficacy and safety). PRESERFLO is already in use in France (marketing authorization and CE marking obtained) and is covered by social security. This technique is highly effective in lowering IOP, but it may be associated with hypotony, although less frequently than with trabeculectomy. The use of a releasable suture placed inside the Preserflo to limit drainage and, consequently, reduce the risk of hypotony has been described with good results in preliminary studies. Nevertheless, it is necessary to evaluate the efficacy and safety of this technical modification in a randomized, prospective clinical trial to better understand whether this modification is beneficial for improving the treatment of patients with glaucoma.

Pseudoexfoliative glaucoma is a glaucoma secondary to pseudoexfoliative syndrome; cataract surgery is often more difficult, with more complications. Tran's cannula is a single-use irrigation system designed for cleaning, with the pseudoexfoliative material remaining in the trabecular meshwork. The main objective of this study is to evaluate the efficacy of the Tran cannula, in comparison with increased irrigation, in lowering intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma and treated for glaucoma, and with an indication for isolated cataract surgery.

Glaucoma is an irreversible optic neuropathy. It is the second most common cause of blindness worldwide. Glaucoma can be treated with topical medications (eye drops), laser or surgery. Traditional surgery is invasive and has a high complication rate (hypotonia, endophthalmitis, cataracts, etc.). As a result, several types of micro-invasive surgery (MIGS) have been developed to reduce the risks of surgery while maintaining their effectiveness in lowering intraocular pressure (IOP). The ELIOS laser system is the only ophthalmological excimer laser designed for the surgical treatment of glaucoma. The aim of the procedure is to ablate the trabecular meshwork and inner wall of Schlemm´s canal ab interno, with the creation of 10 microchannels of 210 um in the trabeculum using the ELIOS laser with a wavelength of 308 nm, in order to improve trabecular outflow to achieve a reduction in IOP. The ELIOS laser is an example of Microinvasive Glaucoma surgery (MIGS) with published results demonstrating efficacy and safety. The ELIOS laser is already in use in France (AMM / CE mark achieved). Its use as part of a prospective interventional study will enable us to collect data in order to treat patients more effectively and improve the quality of care provided to glaucoma patients.
