The last few decades have witnessed smaller incision cataract surgery. Now extending the same logic of early healing, lesser chances of complications and faster recovery to glaucoma surgeries, we are now witnessing increasing number of smaller incision glaucoma filtration surgery. Ex-Press Mini shunt is one such example.
The Ex-Press Mini Glaucoma Shunt was originally developed by Optonol, Ltd. (Neve Ilan, Israel) for implantation under the conjunctiva for controlling intraocular pressure (IOP). This biocompatible device is almost 3 mm long with an external diameter of approximately 400 microns. It is a non-valved, MRI compatible, stainless steel device with a 50 micron lumen. It has an external disc at one end and a spur-like extension on the other to prevent extrusion.
