Understanding the fundamental differences between cryopreserved and dehydrated amniotic membranes is crucial for effective clinical implementation. Research by Sandeep Singh, MD, FAAPMR and colleagues has demonstrated significant differences in efficacy between these 2 forms. Cryopreserved amniotic membrane preserves critical anti-inflammatory, antiscarring, and antiangiogenic factors essential for ocular surface regeneration. The cryopreservation process maintains the integrity of these therapeutic components, delivering them effectively to the ocular surface without degradation.

The key differentiating factor is the preservation of heavy chain hyaluronic acid and pentraxin-3 molecules in cryopreserved versions, which Dr Fahmy describes as the “secret sauce” of amniotic membrane therapy. These molecules are essential for delivering the regenerative properties that improve ocular surface health. In contrast, dehydrated amniotic membranes lose these critical therapeutic components during processing, significantly reducing their clinical effectiveness. This scientific understanding gives practitioners confidence when discussing treatment options with patients and justifying the choice of cryopreserved products.

Clinical experience supports the superiority of cryopreserved amniotic membrane, with Dr Fahmy observing more consistent and effective outcomes compared with dehydrated alternatives. The extensive research supporting cryopreserved amniotic membrane includes documented improvements in symptom relief, epithelial healing, and nerve regeneration. These improvements occur through restoration of the vital connection between corneal nerve cells and epithelial cells, normalizing the neural feedback loop and disrupting the inflammatory cycle that perpetuates ocular surface disease.
