minimally invasive glaucoma surgery

The implant is inserted through the trabecular meshwork, thus bypassing resistance of aqueous flow through the tissue. These devices (the Xen Gel Stent and PRESERFLO [formerly InnFocus] Microshunt) have shown excellent pressure lowering with improved safety over trabeculectomy in studies done outside the United States. The procedure can be performed alone or in conjunction with cataract surgery. Medical and surgical management of glaucoma, cataract and diseases of the anterior segment, comprehensive ophthalmology, cataract surgery, combined cataract and glaucoma surgery, minimally-invasive glaucoma surgery, trabeculectomy, glaucoma drainage device surgery. Open angle glaucoma (OAG) is a disease affecting an estimated 2.8 million people in the United States as of 20101, accounting for an approximate cost of $1.5 billion per year.2 Initial therapy for OAG typically consists of medications that can aid in decreasing aqueous humor production or increasing aqueous humor outflow. Order booklets about glaucoma for your patients. We appreciate support from corporations who believe in our A As an alternative to traditional glaucoma treatments, minimally invasive glaucoma surgery (MIGS) has shown promise for the future management of glaucoma… (2018 update: See note below regarding the CyPass Micro-Stent). During the last 25 years, glaucoma management has been based in the use of pharmaceutical therapies and incisional surgery. [42], The Trabectome, or trabeculectomy ab interno, is a microsurgical device cleared by the U.S. Food and Drug Administration since 2006, used in patients with open angle glaucoma to excise a strip of trabecular meshwork, the tissue primarily responsible for the increased resistance of aqueous outflow in glaucoma. Traditional glaucoma filtration surgeries, such as trabeculectomy and glaucoma drainage implants (GDI), have well-established efficacy in lowering intraocular pressure (IOP), but it comes at the cost of a very high rate of complications. Several operations have been devised using tiny equipment and devices to cut through the trabecular meshwork without damaging any other tissues in the ocular drainage pathway. Free shipping . Abstract Micro- or minimally invasive glaucoma surgeries (MIGS) have been the latest addition to the glaucoma surgical treatment paradigm. Minimally … This article appeared in the While all types of glaucoma surgery share the same goal of lowering eye pressure, MIGS has been specifically developed with the goal of reducing the risk of complications associated with traditional glaucoma surgeries. The 6-millimeter stent is placed through the trabecular meshwork, with one end of the stent sitting directly underneath the conjunctiva, past the outer wall of the sclera. Previously, laser cyclophotocoagulation was reserved for advanced glaucoma that could not be controlled despite trabeculectomy or tube shunts. … Minimally invasive glaucoma surgery (MIGS) has become a reliable standard of care for the treatment of glaucoma when combined with cataract surgery. At five years, the CyPass Micro-Stent group experienced statistically significant endothelial cell loss compared to the group who underwent cataract surgery alone. Aqueous humor is produced in the portion of the eye known as the ciliary body. Using tiny tubes with very small internal openings, the front of the eye is connected to the suprachoroidal space between the retina and the wall of the eye (Glaukos shunts) to augment the drainage of fluid from the eye. [10] The device has also been shown to offer better IOP control than cataract surgery alone up to one year of follow-up in a large randomized controlled FDA study, although the effectiveness was significantly reduced by 2 years. These procedures are currently targeted at patients with mild-to-moderate glaucoma. Minimally invasive glaucoma surgery (MIGS) devices can be are employed in any glaucoma surgery that avoids conjunctival dissection, and includes an ab interno incision for the treatment of patients … What are MIGS? Please enter your question in the Search box below. The ciliary body contains 72 protrusions known as ciliary processes, from which the aqueous is produced. [31] The Hydrus Microstent takes advantage of this property by mechanically dilating and holding open Schlemm’s Canal. They are utilized much earlier in the disease process and when combined with cataract surgery … Offer more modest results than traditional glaucoma surgery, but with the benefit of a safer risk profile. New developments in Micro-Invasive Glaucoma Surgery (MIGS) allow patients to have glaucoma and cataract surgery during one procedure, and most patients with a cataract and open-angle glaucoma … mission to educate glaucoma patients and speed a cure. [34] The XEN Gel Stent was FDA approved on Nov 22, 2016. Text Size. The destruction of these ciliary processes with a diode laser, known as cyclophotocoagulation, can be used to decrease the amount of aqueous humor produced, thereby reducing the intraocular pressure. [6][23][24][26] Data from a large randomized controlled pivotal study (The COMPASS Clinical Study) has reported positive efficacy after 2 years of follow-up and will be submitted to FDA for approval. While they are very often effective at lowering eye pressure and preventing progression of glaucoma, they have a long list of potential complications. More information: Read the Novartis press release. The rate of reoperation for complications was 22% in the tube group and 18% in the trabeculectomy group. This term refers not to a single surgery, but rather to a group … Currently, all therapy for glaucoma is directed at lowering eye pressure, but the fundamental problem in glaucoma is the degeneration of the optic nerve fibers necessary for vision. Stay up-to-date with the latest news about glaucoma, treatments, and research. It can be done at the same time as cataract surgery (a surgery to remove a cloudy eye lens), and may be safer than more invasive surgeries for glaucoma. $46.91. 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. It stands for minimally invasive glaucoma surgery. These procedures may be discussed in a future article. University of California, San Francisco, UCSF Medical Center One of the new and exciting prospects in the treatment of glaucoma is called MIGS, or Minimally Invasive Glaucoma Surgeries. The trabecular meshwork can either be destroyed (Trabectome or Trab360) or bypassed using a tiny snorkel-like device (the iStent).

It stands for minimally invasive glaucoma surgery. Clinical data from a randomized controlled study demonstrates efficacy of the device at 1 and 2 years. Most of the restriction to fluid drainage from the eye rests in the trabecular meshwork. Increase; Decrease; Normal; Current Size: 100%. MIGS procedures work by using microscopic-sized equipment and tiny incisions. Standard glaucoma surgeries, trabeculectomy and external tube-shunts are major and sometimes necessary surgeries. [40], Endocyclophotocoagulation is indicated for the treatment of both open and closed angle glaucoma and is performed in eyes which have already undergone cataract surgery or performed concomitantly with cataract removal. Minimally invasive glaucoma surgery (MIGS) The new technologies and devices, known as MIGS, aim to lower IOP with a higher safety profile than fistulizing surgery (trabeculectomy/drainage … [14], In early 2014, the NeoMedix received a warning letter from FDA regarding marketing practices. [21], It has a microlumen of 300 microns and is designed to augment outflow to the suprachoroidal space in order to control intraocular pressure; it is indicated for the treatment of primary open-angle glaucoma. Studies have found a decrease in intraocular pressure to the mid-teens following the procedure, which has a favorable safety profile. [1], MIGS procedures offer an excellent safety profile, with minimal incidence of complications, especially when compared with other forms of glaucoma surgery.[1][2][6]. [1] MIGS procedures involve a minimally invasive approach, often with small cuts or micro-incisions through the cornea that causes the least amount of trauma to surrounding scleral and conjunctival tissues. Yes It includes different types of implants, stents or procedures used in conjunction with or without cataract surgery to help lower the pressure of the eye for patients with mild to moderate glaucoma. MIGS objective, like all glaucoma surgeries, is to achieve lowering of IOP by either increasing aqueous humour outflow, the fluid that is produced by the eye and fills the space between the cornea and the lens, or decreasing the production of aqueous humour. [5] MIGS procedures can provide the patient sustained IOP reduction while minimizing the risk and complications associated with glaucoma interventions and decrease the dependence of glaucoma medications. [11][12] Safety of the iStent was comparable to cataract surgery alone which is much better than conventional trabeculectomy. [19], The CyPass Micro-Stent is the first MIGS device developed for lowering of IOP through the suprachoroidal space (virtual space between the choroid and sclera created by implantation of the device), a part of the uveoscleral outflow pathway for aqueous humor. They sometimes produced severe inflammation that could reduce vision. MIGS comprises a group of surgical procedures which share common features. [1][2] While MIGS procedures offer fewer side effects, the procedures tend to result in less intraocular pressure (IOP) lowering than with trabeculectomy or glaucoma tube shunt implantation. Alcon's decision and corresponding recommendation was based on an analysis of five-year post-surgery data from the COMPASS-XT long-term safety study. Sponsor opinions are not reflected on our website. Minimally invasive glaucoma surgery (MIGS) is a treatment approach focused on lowering eye pressure in order to prevent or reduce harm to the optic nerve. MIGS are a family of procedures characterized by the use of microscopic-sized equipment and tiny incisions that provide an … While they reduce the incidence of complications, some degree of effectiveness is also traded for the increased safety. [20] Cyclodialysis cleft procedures were initially used to access this pathway with significant IOP lowering, but the cleft was prone to high anatomic variability as well as early postoperative closure due to the lack of a permanent drainage implant with a standardized and uniform conduit. MIGS can be divided in procedures that lower IOP by using micro-stents and minimally invasive procedures. [1][2][3] Studies have shown that the iStent is an effective procedure, typically lowering intraocular pressure to the mid-teens. [11][12][13][14] Common complications include failure to implant the device, touching the iris with the device, and touching the undersurface of the cornea (endothelium) with the device. Dr. Walters is a member of the American Academy of Ophthalmology and the American Glaucoma … Reported adverse reactions include intraocular inflammation, bleeding, and cystoid macular edema (swelling of the retina). Cyclophotocoagulation traditionally has been performed using an external laser through the sclera, known as transcleral cyclophotocoagulation. By performing the procedure from an internal approach, MIGS procedures often reduce discomfort and lead to more rapid recovery periods. Dr Chelvin Sng (MBBChir, MA, FRCSEd) graduated from Cambridge University, UK, with triple first class honours and distinctions.She is amongst the first surgeons in Asia to be accredited in the use of several micro-invasive glaucoma surgery … [4] Increased intraocular pressure (IOP) is the main and only modifiable risk factor, attributed to the progression of the disease. It is called MIGS, the acronym for minimally invasive glaucoma surgery, and it is the biggest development in glaucoma surgical treatment in many years. [30] The Hydrus Microstent is the longest of the MIGS devices (8-millimeter long implant), and similar to the iStent it is designed to increase trabecular outflow. These procedures are FDA-approved but generally don’t get the eye pressure very low so are most useful in early to moderate stages of glaucoma. MIGS procedures involve a minimally invasive approach, often with small cuts or micro-incisions through the corneathat causes the least amount of trauma to surrounding scleral and conjunctival tissues. A Cochrane Review published in December 2019 did not find any published clinical trials to assess whether the InnFocus Microshunt is safer and more comfortable for patients than standard glaucoma surgery (trabeculectomy). Standard glaucoma surgeries — trabeculectomy and ExPRESS shunts, external tube-shunts like the Ahmed and Baerveldt styles — are major surgeries. [38][39] Recent advances have now allowed a diode laser to be combined with a camera (endoscope) allowing for direct visualization of the ciliary processes during the ablation (Endo Optiks, Beaver Visitec, Waltham, MA). The InnFocus Microshunt is a small tube, 8 mm in length, that is inserted in to the eye to help lower intraocular pressure and reduce the need for medications. The iStent Trabecular Micro-Bypass Stent, or simply iStent, is the smallest implantable medical device, designed to lower intraocular pressure by facilitating trabecular outflow of aqueous fluid. [27][28] The CyPass device has been CE-marked since 2009. We conducted a budget impact analysis of MIGS … These surgical treatment options vary from Minimally Invasive Glaucoma Surgery (MIGS), which is often done in conjunction with cataract surgery, to advanced incisional surgery like implantable tube-shunts … The XEN Gel Stent is an implantable transcleral microsurgical device that allows the aqueous fluid to drain from the anterior chamber into the subconjunctival space, a pathway utilized by traditional trabeculectomy and glaucoma drainage device surgeries. A new class of treatments called minimally invasive glaucoma surgery (MIGS) may reduce IOP and offer a better safety profile than more invasive procedures. Enter Minimally Invasive Glaucoma Surgery, or MIGS. [8][9], The iStent is the first MIGS device to get FDA approval for implantation in combination with cataract surgery. … The Hydrus Microstent is an implantable MIGS device for the treatment of primary open angle glaucoma; implantation of this device can be performed in conjunction with cataract surgery.
