AmnioGuard

Super Strength, Powerful Properties.

AmnioGuard® is an ultra-thick, cryopreserved amniotic membrane graft that suppresses inflammation, promotes healing, and provides durable tensile strength to avoid surgical challenges associated with reconstructive procedures.1-4

Technology

Seeing a Difference.

Our biologic ocular transplantation tissue grafts help your patients heal better and faster. BioTissue’s CryoTek® cryopreserved amniotic membrane grafts are the only amniotic membrane products cleared by the FDA for their therapeutic properties in repairing and healing ocular surface inflammation.5

01

AmnioGuard helps achieve complete epithelialization, without wound dehiscence and excellent prosthesis fit at final follow-up with no clinically significant complications.3

02

AmnioGuard serves as an excellent alternative to other homologous tissue grafts for ocular surface reconstruction and management of Anophthalmic socket contracture.3

03

AmnioGuard has been shown to help promote superior stability in post-glaucoma treatment and optimal healing in post-oculoplasty surgery.1

Frequently Asked Questions

Can AmnioGuard be used as an alternative to commonly used Autograft and Allograft?

AmnioGuard is a beneficial alternative to other commonly used grafts. However, it could be used in combination with a mucosal graft to deliver a premium outcome. In contrast to Autograft such as mucosal graft, other allografts available are dehydrated in nature and don’t retain the tensile strength and many of the key biologics responsible for facilitating healing.

How can AmnioGuard be used in the ocular surface reconstruction procedures?

AmnioGuard can be either sutured (using an 8-0 Vicryl suture) or glued (fibrin glue), or both to the surrounding conjunctiva and underlying sclera. Fibrin glue can shorten the surgery time and decrease conjunctival inflammation and discomfort.

What are some of the disadvantages of autologous substitute graft?

The disadvantages of autologous substitute grafts include an undesirable cosmetic appearance, foul discharge, graft harvesting, donor-site morbidity, and contraction of the graft.
