AMNIOTIC MEMBRANE
The Amniotic Membrane (AM) is a thin tough sac of membrane that protects the embryo during pregnancy against any injuries that can lead to fetal death. The AM is the only tissue designed by nature specifically as a universal transplant, it protects the baby and ensures there is acceptance by the mother’s immune system. The membrane itself consists of a combination of tissue layers with protective and therapeutic properties, making amnion a unique membrane in the human body. The AM is the inner avascular layer of the three-layered fetal membrane.
AM tissue has been an emerging alternative for clinicians to rapidly and effectively treat ocular surface conditions. As cited by the American Academy of Ophthalmology, “it’s an avascular fetal membrane lying deep to the chorion and is harvested in a sterile environment from placental tissue obtained during elective cesarean sections”.
OUR AMNIOTIC MEMBRANES
At Visionary Biologics, we strive to create the world's best dehydrated sutureless grafts. Due to their ease of use, long shelf life, and incredible results, dehydrated sutureless grafts have become an increasingly popular treatment by optometrists and ophthalmologists for conditions that may lead to corneal scarring or cause ocular discomfort.
Our dehydrated sutureless grafts are composed a flat disc of tissue without an uncomfortable stabilizing outer ring made of PMMA material. It should be stressed that at Visionary Biologics we screen all our harvested tissues for diseases before treating them with broad-spectrum antibiotics, this process is arguably the most thorough in the industry. We provide our dehydrated AM allograft products from human amniotic tissue in 3 different disc oriented sizes: Visi 9 (9mm); Visi 12 (12mm); and Visi 15 (15mm).
PROCESS OF PUTTING ON THE CONTACT LENS IN THE CLINIC/LAB
The application of the lenses is usually done by the optometrist or ophthalmologist. It can be while the patient is seated in an exam chair with head against the back rest or in a minor surgery room, lying down in a supine position. Here are the steps for insertion provided by the American Academy of Ophthalmology:
1. Remove the disk carefully from inner package—the dehydrated tissue is very thin and light in weight.
2. Place topical proparacaine on the ocular surface.
3. Place the AM disk onto the ocular surface.
4. Smooth the graft onto the ocular surface.
5. Place a few drops of sterile saline to rehydrate the membrane.
6. Place a bandage contact lens to cover the membrane and corneal surface.
Depending on the clinical condition, the AM typically dissolves over one week. Case studies suggest very positive patient outcomes when it comes to treatment. The convenience of non-invasive or suture-less methods far outweigh temporary discomfort upon the lenses' application.
