Glaucoma tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant or the ExPress Mini Shunt and the later generation pressure ridge Molteno implants. These are indicated for glaucoma patients not responding to maximal medical therapy, with previous failed guarded filtering surgery (trabeculectomy). The flow tube is inserted into the anterior chamber of the eye, and the plate is implanted underneath the conjunctiva to allow a flow of aqueous fluid out of the eye into a chamber called a bleb. The ongoing scarring over the conjunctival dissipation segment of the shunt may become too thick for the aqueous
Minimally invasive glaucoma surgery vision and take extra time to recover. The surgery site can scar over time and the pressure can go back up. In early 2014, the NeoMedix received a warning letter from FDA regarding marketing practices. Minimally invasive glaucoma surgery Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. MIGS comprises a group of surgical procedures which share common features. MIGS procedures involve a minimally invasive approach, often with small cuts or micro-incisions through the cornea that causes the least
