Abstract

Purpose: Corneal diseases are the fourth reason for blindness around the world which can be treated with corneal transplantation as a gold standard approach. However, alternative strategies get more valuable to peruse due to the challenges of donor shortage and failing the corneal transplantation procedure. This study aims to find the trend of biological products introduced to the market for corneal regeneration. Methods: Biological products introduced by different companies were evaluated in this review. The available and underevaluation products introduced to market are reported in this review. This search was done by keywords related to corneal/product, corneal/biological scaffold, corneal/biological product, corneal/allograft, corneal/xenograft, eye drops, biological eye drops, and amniotic membrane/cornea. Results: Decellularized products of xenogeneic or allogeneic cornea and amniotic membrane matrixes were mostly employed as corneal scaffold. In addition, biological eye drops, gels, and (platelet-rich plasma) PRP are used in several reports as bioactive ingredients. Conclusion: Herein, the most important issue about biological products that researchers are involved in is preserving the most active ingredients after decellularization or extraction process with minimum modification along with reasonable final cost. Lay Summary: Although at first glance cornea appears as simple avascular collagenous tissue, corneal diseases are the fourth leading cause of blindness according to the WHO reports. Currently, corneal transplantation has been chosen as a gold standard treatment. In recent years, the rising growth of smart biomaterials can be considered as a turning point in modern medicine by using smart scaffolds, a hydrogel with self-healing properties that could be potentially loaded with a drug, autologous cells, or stem cells. Here, we review available and under evaluation products introduced to the market to some extent overcome the cornea transplantation side effects. © 2023, The Author(s), under exclusive licence to The Regenerative Engineering Society.
