Proprietary Technology

The FORMULA/5™ Process

The FORMULA/5™ processing method is designed to retain extracellular matrix (ECM), natural growth factors, and other regulatory proteins to support the full healing cascade.

FORMULA/5™ Process

The Most Gentle Drying Process in the Industry

FORMULA/5™ preserves the natural ECM structure, including collagen, glycoproteins, and elastin. Our proprietary process:

  • Ensures minimal manipulation
  • Uses no harsh chemicals
  • Provides the most gentle drying process in the industry
  • Engineered to meet stringent FDA regulations and AATB standards
  • Delivers a product that stores easily, transports safely, rehydrates quickly, and handles well at application
iPatch™ and xPatch™ with FORMULA/5™

Key Product Attributes

  • Bioresorbable — naturally absorbed during healing
  • Retains growth factors — FORMULA/5™ preserves the biological healing profile
  • Bi-directional application — either side can face the ocular surface
  • No preparation required — ready to apply at point of care
  • Air-dried processing — gentle ambient drying, no heat dehydration
  • Reduced scar tissue formation — anti-fibrotic properties of amniotic membrane
  • Naturally non-immunogenic — derived from immune-privileged placental tissue
  • Semi-permeable protective barrier — allows nutrient exchange while protecting the surface
  • Stores at room temperature — no freezer, no special storage requirements

Clinical Applications

Common Clinical Applications

Human amniotic membrane is a biocompatible allograft shown to provide substantial benefit in treating conjunctival and corneal disease.

Keratitis

Corneal inflammation supported by the anti-inflammatory properties of amniotic tissue.

Corneal Ulcers

Biological scaffold and barrier coverage for non-healing stromal and epithelial defects.

Neurotrophic Keratopathy

Support for corneal healing where nerve function is compromised.

Recurrent Corneal Erosion

Fostering epithelial healing, reducing inflammation, and promoting the adhesion of the corneal epithelium to the basement membrane.

PCED

Persistent corneal epithelial defects that have failed conventional medical therapy.

Chronic Dry Eye

Adjunct therapy for patients with moderate-to-severe dry eye and ocular surface disease.

Application Instructions

Placing the Allograft

iPatch™ is designed for simple, no-prep placement at the point of care.

  1. 1Remove allograft from the inner pouch using dry toothless forceps.
  2. 2Place the dry allograft directly on the ocular surface. Avoid exposing to moisture or humidity until placed. Gently flatten the allograft over the defect using toothless forceps or a sterile eye spear sponge.
  3. 3If needed, hydrate using sterile isotonic solution once placed on the defect.
  4. 4Cover with a bandage contact lens.

Clinical Applications

Common Surgical & Clinical Applications

Human amniotic membrane is a biocompatible allograft shown to provide substantial benefit across a broad range of surgical and wound care applications.

Pterygium Surgery

Used as a graft to cover the exposed sclera after removal of a pterygium, significantly lowering recurrence rates.

Corneal Ulcer & Defect Repair

Applied to promote healing of non-healing corneal ulcers, persistent epithelial defects (PEDs), and infectious keratitis.

Conjunctivochalasis

Amniotic membrane is used to reconstruct the ocular surface after the excision of redundant (loose) conjunctiva, especially in refractory cases.

Strabismus Surgery

Used in complex or revision strabismus surgeries to reduce postoperative scarring and restrictive adhesions.
