Minimally Invasive Glaucoma Surgery (MIGS)

Glaucoma is one of the more common vision stealing diseases that we see in our practice. It is an insidious disease in that there are no symptoms until the progression is very advanced and vision that is lost cannot be recovered (unlike cataracts). Generally thought to be a problem of too high pressure in the eye, the common factor in all the glaucomas is the damage to the optic nerve that gradually constricts the vision until it becomes as if you were looking through a straw.

Although controlling systemic issues, such as blood pressure, is important, the main thrust of glaucoma therapy is to lower the ocular pressure. This has been shown to markedly slow down the progression of glaucoma. Until recently we have had drops, laser and traditional glaucoma surgery as methods of treating this problem. Now, we have MIGS!

Minimally Invasive Glaucoma surgery can be done in eyes that have had prior cataract surgery or at the same time as cataract surgery. Using special lenses to verify placement, a tiny stainless steel tube is placed in the eye, bypassing where the obstruction to fluid drainage is occurring and lowers the pressure. Pts are unaware of the device and it requires no further intervention. Recovery is swift and the complication rate is much lower than traditional surgery. The iStent device is reported to lower pressure as much or more than the best single medical agents available.

Dr. Davis is currently being trained in this procedure and Precision Eye Care will be offering this new and innovative therapy starting in April of this year.
