Glaucoma Surgery
Glaucoma surgery serves as an essential treatment option for patients who do not achieve adequate intraocular pressure control through medications or laser therapies. Trabeculectomy is one of the most established surgical procedures for glaucoma, wherein a small flap is created in the sclera to facilitate the drainage of aqueous humor, thus lowering intraocular pressure. This procedure has shown considerable success in managing various types of glaucoma but can be associated with risks such as infection and over-drainage. In recent years, the PreserFlo MicroShunt has emerged as an innovative alternative to traditional filtration surgery. This small, device-based approach allows for controlled drainage of aqueous fluid, reducing complications associated with conventional trabeculectomy.
Microshunt : Preserflo Surgery
The PreserFlo MicroShunt surgery is an innovative and minimally invasive approach designed to manage glaucoma through controlled aqueous humor drainage. This procedure involves the implantation of a small, flexible device that facilitates the outflow of fluid from the anterior chamber of the eye to the subconjunctival space. Unlike traditional filtration surgeries, the PreserFlo MicroShunt is engineered to provide a more gradual and consistent reduction in intraocular pressure, significantly decreasing the risk of complications such as over-drainage and hypotony. The microshunt’s design allows for a smaller incision and less tissue disruption, resulting in quicker recovery times and less postoperative discomfort for patients. As a cutting-edge advancement in glaucoma treatment, the PreserFlo MicroShunt presents a promising option for patients seeking effective long-term management of their condition while preserving their quality of life.
