Do you or someone you know have glaucoma? For those with this eye condition, worry can be common.

Luckily, advances in eye care technology and more minimally invasive glaucoma surgery options are helping to reduce the anxiety surrounding the diagnosis and treatment of this often chronic disease. See your options here from eye specialist in singapore → Dr Chelvin Sng :

It is important to understand, though, that the results vary on an individual basis. Nonetheless, successful outcomes from minimally invasive techniques allow for some long-term relief from debilitating symptoms caused by damage to the optic nerve due to glaucoma. In this blog post, we’ll cover everything you need to know about these forms of minimally invasive glaucoma surgeries to help you make informed decisions when discussing treatment options with your ophthalmologist!

What is Minimally Invasive Glaucoma Surgery (MIGS)?

Minimally Invasive Glaucoma Surgery (MIGS) is a type of eye surgery used to help treat glaucoma. MIGS reduces intraocular pressure, improving vision and preventing further vision loss.

This type of surgery involves using tiny instruments and specialized tools to open up the eye’s drainage canals, allowing fluid to drain more easily. This relieves pressure in the eye and helps reduce future damage.

And generally, there are two types of Minimally Invasive Glaucoma Surgeries: These include, Minimally Invasive Glaucoma Surgeries that drain internally and those that drain externally.

MIGS procedures that internally drain fluids offer a safe and effective treatment option for patients with mild to moderate glaucoma. These procedures involve implanting a special device at the angle of the eye, bypassing the trabecular meshwork known to impede drainage.

The implant allows fluid to flow much better internally into the blood vessels while still providing vision improvement through cataract surgery. At the same time, these MIGS implants allow patients to reduce their intake of glaucoma medications with minimal additional risk than routine cataract surgery alone.

Even when glaucoma is well controlled with eyedrops, MIGS can provide an extra layer of protection by allowing for improved drainage within the eye. Externally draining MIGS (micro-invasive glaucoma surgery) is a minimally invasive option for treating more advanced stages of glaucoma.

These procedures involve the placement of a small device in the eye, which creates a space called a bleb where fluid can drain from the eye. This is seen by many as an effective way to reduce eye pressure.

As such, it has rapidly gained popularity among ophthalmologists and other specialists due to its minimal invasiveness and relatively low risks of surgical complications. Compared to trabecular bypass MIGS, externally draining MIGS is often preferred when it comes to more advanced cases of glaucoma.

This is because they provide greater efficacy when it comes to relieving intraocular pressure and thereby reduce the risk of further damage to the optic nerve associated with this condition. While this is true, careful consideration must be taken when deciding on any type of MIGS procedure, particularly those which drain externally.

Surgery should only be considered after extensive consultations with medical professionals and a thorough evaluation of all potential risks and benefits involved in each case. Through this process, patients can make an informed decision about which treatment best suits their condition and needs.

Ultimately, these procedures are an excellent way for those suffering from mild to moderate glaucoma to improve their sight and overall health without relying heavily on medications. They generally require no stitches or blades and can be performed without a full-scale incision. When choosing an appropriate technique for a patient, ophthalmologists consider factors such as age, medical history, the severity of glaucoma, anatomic features of the eyesight that may affect visualization during surgery, other factors related to ensuring successful outcomes for each individual case.

How Successful is MIGS for Glaucoma Patients?

MIGS has been proven to be highly effective in managing the disease and reducing vision loss due to ocular hypertension. Clinical trials have demonstrated that MIGS can produce a significant decrease in intraocular pressure over 24 months with a concurrent reduction in the usage of prescription eye drops.

These results indicate that MIGS is an effective method of treating glaucoma, as intraocular pressure and medication use are two major factors leading to vision loss from this condition. Furthermore, MIGS does not require the same level of invasive surgery as traditional options such as trabeculectomy, thus limiting the risks associated with open-angle glaucoma surgeries.

Additionally, MIGS procedures involve smaller incisions than those usually required for traditional approaches, resulting in minimal scarring or damage to surrounding tissues. Therefore, MIGS is considered less risky than most other treatments while achieving comparable results in eye pressure control and prevention of further vision loss.

While MIGS cannot restore sight already lost due to glaucoma or other conditions, current scientific evidence suggests it can be used to delay future vision loss by controlling ocular hypertension through minimally invasive means. Furthermore, its comparatively low-risk profile makes it a great choice for many patients who may be reluctant or unable to undergo more involved surgical interventions such as trabeculectomy or cataract surgery. However, it’s still important to consult your doctor about all available options so you can make an informed decision about your treatment plan before proceeding with any procedure.

Are There Any Risks?

MIGS carries some risks, just as any other form of surgery does. Most commonly, these are associated with the implanted devices and the possibility of infection or device malfunction. However, these risks are generally outweighed by the benefits associated with MIGS.

The most important thing for glaucoma patients to consider is that the long-term success of any minimally invasive surgery depends upon consistent follow-up care. Even after a successful procedure, it is critical for glaucoma patients to continue to monitor their intraocular pressure and receive regular eye examinations.

Closing Thoughts

MIGS is a safe and effective method of controlling ocular hypertension. It carries many benefits over traditional treatments, including minimal scarring, smaller incisions, and reduced risk of infection or device malfunction.

To ensure success, patients must receive regular follow-up care and continue monitoring their intraocular pressure. With ongoing monitoring and care, MIGS can be a great option for many glaucoma patients.
