What is a Molteno implant?

Implanted in thousands of patients worldwide, the Molteno3 Glaucoma Drainage Device has been clinically validated to deliver consistent, long-term reduction in intraocular pressure (IOP) in cases of advanced or complex glaucoma.

How long does a Baerveldt implant last?

Studies show that if Baerveldt implants are still functioning successfully after five years, most continue to function long after that as well.

How long does glaucoma implant surgery take?

What is glaucoma implant surgery? This type of surgery is used to treat several types of glaucoma, including congenital glaucoma, neovascular glaucoma, and glaucoma caused by an injury. It’s done in a hospital and usually takes 1 to 2 hours.

Can a Baerveldt implant be removed?

Strabismus surgery with preservation of the filtering bleb related to a GDD can reportedly be successful in many cases [3]; however, complete removal of the fibrous capsule surrounding the implant and involved adjacent structures might be required in some severe cases [4].

How does the Ahmed glaucoma valve work?

The Ahmed valve is one type of aqueous shunt implantation that drains the aqueous humor fluid from inside the eye to a small capsule (often called bleb) behind the eyelid. Draining the fluid continuously by this method reduces pressure on the optic nerve and can prevent further loss of vision.

What is baerveldt surgery?

The Baerveldt shunt is a glaucoma drainage device that is implanted into the eye to reduce intraocular pressure (IOP) by draining aqueous humor fluid. Aqueous humor is not the same as tears — in patients with glaucoma, the buildup of aqueous humor fluid causes high intraocular pressure (IOP) that can damage vision.

How long do glaucoma implants last?

Overall, GDD implantation successfully controlled glaucoma in 86, 85, 81, 78, 79, 76 and 73% of eyes at 1, 2, 3, 4, 5, 7 and 10 years, respectively. At last follow-up IOP was successfully controlled in 67% of eyes. The success rate of the Ahmed implant was 68%, and of the Baerveldt implant 56% at last follow-up.

How long does a baerveldt shunt last?

Success rates for the Baerveldt procedure have been reported in the 70-80% range after 5 years, and many patients achieve long-lasting results. These rates are higher than for some other aqueous shunt procedure types because the Baerveldt plate size covers a larger surface.

How successful is Ahmed valve?

Moreover, the overall success rate of Ahmed valve implantation ranges from 63% to 100% at one year, while the maximal long-term follow-up success rate has been reported to be 49% at five years [6].

How long does an Ahmed valve last?

How Successful is the Ahmed Valve? Research studies are ongoing, but success rates for aqueous shunt procedures are within the 60-80% range after 5 years. However, every patient’s eye anatomy and stage of glaucoma is different.
