Filter by:Glaucoma is a common eye disease that can lead to blindness. The only known way to reduce the rate of disease progression is by reducing the pressure in the eye (the intraocular pressure, IOP). Selective laser trabeculoplasty (SLT) is an ophthalmic laser intervention with the purpose of reducing the IOP. SLT can be performed in different ways, with four of the treatment protocols being evaluated in the Optimal SLT (OSLT) trial. SLT is a repeatable procedure, but scientific evidence is scarce regarding more than one repetition. In this trial, patients included in the OSLT trial will be invited to the extended trial (OSLT-R), for further follow-up and re-treatment with SLT, if needed.
The purpose of this study is to prolong observational follow-up up to 36 months of patients already implanted with a novel interposition supraciliary implant.
Glaucoma is the second most common blindness disease in the world, second only to cataracts. The current treatment of glaucoma is mainly to reduce intraocular pressure.At present, two commonly used surgical methods are trabeculectomy and implantation of drainage valve. These methods are superior to drug treatment in reducing intraocular pressure, but the effect duration of these two methods is not long, and there may be serious complications and failure. Compared with traditional glaucoma surgery, MIGS may have better safety.The XEN45 gel implant is a collagen tube with a length of 6 mm and a diameter of 45 µm, which creates a new channel for drainage of aqueous humor by connecting the anterior chamber and the subconjunctival space. The implant is composed of porcine gelatin cross-linked with glutaraldehyde, and has good biocompatibility and tolerance. Therefore, after the advent of XEN45 products, more and more studies have shown that this treatment has excellent safety and effectiveness in reducing intraocular pressure in patients with open-angle glaucoma. Considering that the XEN45 gel stent has been in the market for a relatively short time, we conducted this prospective study to investigate the effect of XEN45 surgery in the treatment of primary open-angle glaucoma, in order to support ophthalmologists in formulating the best surgical plan for patients. The promotion of this surgical method.

Open angle glaucoma (OAG) is considered a common cause of irreversible vision loss worldwide. It is an optic neuropathy associated with progressive loss and degeneration of the retinal ganglion cell layer (RGC) and its axons (retinal nerve fiber layer; RNFL), which lead to neuroretinal rim excavation and corresponding visual field defects.
A prospective, nonrandomized, open label study to evaluate the safety and IOP lowering effectiveness of the Streamline Surgical System, in patients with mild-to-moderate open angle glaucoma undergoing cataract surgery.
Glaucoma is a progressive optic neuropathy that results in a loss of contrast sensitivity and visual field if not detected and treated. When glaucoma patients undergo cataract surgery, they are often not ideal candidates for many existing presbyopia correcting IOLs as they reduce contrast sensitivity because of the splitting of light and are more likely to have visual disturbances secondary to diffractive steps in the IOL design. This is largely because of a higher rate of ocular surface disease and meibomian gland dysfunction in this patient population due to the chronic utilization of topical drops. As a result of this, patients with glaucoma currently receive aspheric monofocal IOLs during cataract surgery, which are lenses with minimal loss of contrast sensitivity but only one point of focus (typically targeted for distance). This necessitates the use of glasses for near and intermediate vision and has an impact on quality of life for these patients. The Vivity Extended Depth of Focus (EDOF) IOL is a new technology that maintains uncompromised distance vision and provides improved intermediate vision correction, reducing the need for glasses. This lens uses a new optical system with no diffractive steps in the IOL; trials in non-glaucomatous patients have shown the rate of visual aberrations to be comparable to an aspheric monofocal IOL which are currently the standard of care in patients with glaucoma. There is no published data on outcomes of this IOL in patients with primary open angle glaucoma (POAG) or ocular hypertension (OHT). Studies are required to evaluate the clinical success of this new lens technology in glaucomatous patients. This will be the first study in Canada to report clinical outcomes of the Vivity IOL in this patient cohort.
Primary open-angle glaucoma (POAG) is a chronic eye disease in which the only validated treatment is to lower intraocular pressure (IOP). It is the 2nd leading cause of blindness worldwide. The iStent® inject and inject W is an implantable device that is part of a new entity of so-called minimally invasive glaucoma surgery whose goal is to lower IOP with minimal tissue disruption in order to avoid the complications of conventional glaucoma surgery. This surgery is used in conjunction with cataract surgery in France. The primary objective is to study the 1-year efficacy and safety of combined cataract and iStent inject and inject W in the management of POAG in an observational, retrospective, controlled study of a cohort of POAG patients undergoing cataract surgery only.
The purpose of this study is to evaluate the long-term safety and effectiveness of the OMNI® Surgical System in subjects who were treated under protocol #06213
The objective of this study is to evaluate the effectiveness (Intra-Ocular Pressure lowering) and safety of Direct Selective Laser Trabeculoplasty (DSLT) in ethnic Chinese subjects with Primary Open Angle Glaucoma or Ocular Hypertension.
