Minimally invasive glaucoma surgery: MIGS

MIGS_TUBO_XEN
A set of very safe and non-aggressive techniques.
Indicated in cases of ocular hypertension and glaucoma.
Can be combined with cataract surgery.

¿Qué son las MIGS (Minimally Invasive Glaucoma Surgery)?

The term MIGS (Minimally Invasive Glaucoma Surgery) includes over a dozen minimally invasive surgical techniques, aimed at relieving the intraocular pressure of glaucoma. To do so, they are based on implanting drainage micro-devices or laser procedures that allow the aqueous humour to exit, hence preventing this liquid from accumulating inside and ending up damaging the optic nerve.

At the Miranza clinics, we offer you the latest innovations in the field of MIGS, which is applied safely and expertly. These procedures have been developed over the last few years as an alternative to traditional glaucoma surgery, such as trabeculectomy, which achieves a greater reduction in intraocular pressure, but can lead to a higher probability of intra- and postoperative complications.

One of the main advantages of MIGS is that we can use it at the same time as performing a cataract surgery, thus increasing the hypotensive effect. Moreover, we solve two vision problems in a single surgery, without making additional incisions and avoiding having to undergo two postoperative procedures.

Enfermedades oculares que tratan las MIGS

We indicate minimally invasive surgical techniques for glaucoma in cases of intraocular hypertension or mild glaucoma that do not respond to drug treatment, or if, for various reasons, you cannot receive this medication. MIGS helps us to prevent the disease from progressing, hence turning surgery into an option at increasingly earlier stages thanks to the safety it provides.

In any case, if you have more advanced glaucoma and this is not the ideal technique for you, you should know that conventional glaucoma surgery is currently less aggressive thanks to technological advances.

The drainage tubes we insert to allow the aqueous humour to exit, barely 1 mm in diameter, are biocompatible and do not require sutures to stay in place.

Compared to classic glaucoma surgery, MIGS is a shorter operation (around 10 minutes) and allows for a 2 to 3 times faster recovery. After the surgery, which is performed on an outpatient basis and under topical anaesthesia, you will soon be able to resume your daily activities, while following the prescribed treatment with antibiotic and anti-inflammatory drops to prevent a possible infection and promote the healing process.

In general, MIGS techniques entail fewer complications than classic surgeries, hence reducing the chances of bleeding or damage to nearby eye structures. Furthermore, the risk of a sudden drop in intraocular pressure (hypotonia) with MIGS is also much lower. Nonetheless, it is important that you have follow-up check-ups to ensure that intraocular pressure remains stable, both in the immediate postoperative period and in the long term, since glaucoma is a disease that requires ongoing control.
