Glaucoma Drainage Implant for Penetrating Trabeculectomy
Glaucoma Drainage Implant for penetrating trabeculectomy Material
Glaucoma Drainage Implant for penetrating trabeculectomy is
produced with biomaterial ethoxyl methacrylate
ester/methylmethacrylate copolymer(2-HEMA-co-MMA), which is
nontoxic, has no immune ewsponse, has good biological
compatibility, and cannot be absorbed by tissue. As materials of
intraocular lens, it has been clinically applied in ophthalmology
for more than ten years, and is universally accepted as good
intraocular implantion material by ophthalmology circle.
Glaucoma Drainage Implant for penetrating trabeculectomy has two
kinds: type FPT(for penetrating trabeculectomy) and type FNPT(for
nonpenetrating trabeculectomy). The overall length of type FNPT is
4.5mm, and the width of slot is 0.7mm. The length of side of type
FPT is 3.5mm.There are 4 holes on the Glaucoma Drainage Implant,
which used for fixation on sclerotic bed and osmosis of aqueous
humor. To implant the Glaucoma Drainage Implant into resected deep
sclerotic bed to form a cavity which is called aqueous humor "pond"
or "depressurizing room" the upper bottom of linguiform one is
exposed to the outside of sclerotic valve, that is made for aqueous
humor being drained from the "pond", "cavity" to the underside of
conjunctiva, and promoting the formation of new aqueous humor
channel, and thus to achieve the goal of reducing intraocular
pressure.
Characteristics of Glaucoma Drainage Implant for penetrating trabeculectomy
1. Raw material: Hydrophilic acrylate. .
2. Which has good biological compatibility, and cannot be absorbed
by tissue. .
3. Prohibit the growth of fibrocyte, and prevent the formation of
filter channel cicatricle. .
4. To impel the formation of new aqueous humor drainage channel. .
5. Distributary of aqueous humor is formed after the implantation
of drainage device.
6. It is safe for long-term usage, and intraocular pressure can be
effectively controlled. .
7. To increase the success rate and reliability of Glaucoma
operation.
