Glaucoma Valve Model FPT for Glaucoma Surgery
What is Graucoma?
Glaucoma is a common ophthalmic disease with high blinding rate.
Once definite diagnosis is made, operative treatment should be
provided early. Traditional filtration operation mostly adopts
Trabeculectomy to drain aqueous humor to the outside of eyeball(the
underside of conjuctiva) thus to reduce intraocular pressure.
Filter channel is cicatricle fiberization shall occur among partial
patients after Trabeculectomy, so as to the aqueous humor channel
is reblocked and the intraocular pressure is raised continuously,
and so as to the patients go blind. The design intention for our
developing this product is as follows:putting a drainage device
under the resected sclerotic value to form a frame to prevent the
adhesion between sclerotic valve and reticulum trabecula and
maintain the existence of functional liquid cavity, and effectively
drain aqueous humor from the inside of eyeball and liquid cavity to
the underside of conjunctiva, and thus achieve the goal of reducing
intraocular pressure and improve the reliability of Trabeculectomy.
Glaucoma Valve Model FPT for Glaucoma Surgery Material
Glaucoma Value Model FPT for Glaucoma Surgery is produced
biomaterial ethoxyl methacrylate ester/methyl methacrylate
copolymer(2-HEMA-co-NMA) which is nontoxic, has no immune response,
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 implantation material by
ophthalmology circle.
Glaucoma Valve Model FPT for Glaucoma Surgery Material Structure
and Working Mechanism
Glaucoma Valve Model FPT for Glaucoma Surgery has four holes. Used
for fixation on sclerotic bed and osmosis of aqueous humor, implant
the Glaucoma Valve Model FPT for Glaucoma Surgery into resected
deep sclerotic bed to form acavity 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 acheive the goal of reducing intraocular
pressure.
Characteristics of Glaucoma Valve Model FPT for Glaucoma Surgery
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.
