The first glaucoma drainage implant was developed in 1966. [2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants.
Reoperation after failed trabeculectomy or tube shunt is very challenging. Trabectome surgery is a minimally invasive alternative to a repeat filter or shunt. Studies of patients undergoing trabectome surgery after a failed tube shunt have shown a statistically significant reduction in intraocular pressure after one year [42].
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few ...
During the last 25 years, glaucoma management has been based in the use of pharmaceutical therapies and incisional surgery. [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.

Primary congenital glaucoma is a rare eye condition that is present at birth or develops early in childhood. It occurs due to improper drainage of the eye's fluids, which leads to increased pressure inside the eye, known as intraocular pressure .
Secondary glaucoma indicated after congenital cataract surgery is found between 6 and 24% of the cases noted, whereas, secondary glaucoma caused by primary IOL implantation was observed as 9.5%. [5] Additionally, for patients with aphakia and secondary IOL implantation, 15.1% of the cases were determined. [ 5 ]
