Introduction and background

The corneal endothelium, a monolayer of specialized cells located at the posterior surface of the cornea, plays a crucial role in maintaining corneal clarity and transparency by regulating hydration and ion transport [1]. Corneal endothelial dysfunction, often resulting from aging, trauma, or disease, can lead to corneal edema, opacification, and loss of vision. Current treatment options, such as corneal transplantation, face limitations, including donor scarcity, graft rejection, and potential complications [2]. Corneal endothelial regeneration holds significant promise for addressing the limitations of traditional treatments. Restoration of endothelial function can alleviate corneal edema and improve visual outcomes without invasive surgical interventions. However, achieving effective and long-lasting endothelial regeneration remains a considerable challenge in ophthalmology [3].

Nanoparticle-mediated cell delivery is a novel and promising approach for enhancing corneal endothelial regeneration. By leveraging the unique properties of nanoparticles, such as their small size, high surface area-to-volume ratio, and tunable surface characteristics, researchers aim to efficiently deliver therapeutic cells to the target site within the cornea. This strategy can improve cell survival, integration, and therapeutic efficacy while minimizing off-target effects and immune responses [4]. This comprehensive review aims to provide an in-depth analysis of the advancements in nanoparticle-mediated cell delivery for corneal endothelial regeneration. By examining the current understanding of corneal endothelial dysfunction, the importance of regeneration, and the role of nanoparticle-based approaches, this review seeks to elucidate the potential of this innovative therapeutic strategy. Furthermore, by discussing critical studies, mechanisms of action, challenges, and future perspectives, this review offers valuable insights for researchers, clinicians, and stakeholders invested in developing novel treatments for corneal endothelial disorders.

Review

Current treatment modalities for corneal endothelial dysfunction

Corneal Transplantation Techniques

Several corneal transplantation techniques are employed to address various corneal conditions, each tailored to suit specific patient needs. Penetrating keratoplasty (PK) involves the transplantation of a full-thickness cornea obtained from a donor. This procedure entails the removal of a circular piece of the damaged cornea from the center of the eye, which is then replaced with the donated cornea. The new cornea is secured using tiny stitches, forming a star-like pattern around the edges [5]. Descemet stripping endothelial keratoplasty (DSEK) and Descemet membrane endothelial keratoplasty (DMEK) are selective transplantation procedures targeting the endothelial layer. Both involve the removal of the patient’s Descemet membrane, followed by the transplantation of donor corneal endothelium and stroma. DMEK utilizes a thinner layer of donor tissue compared to DSEK, offering advantages in surgical outcomes and visual recovery [6].

Anterior lamellar keratoplasty (ALK) techniques selectively replace diseased tissue in the front corneal layers while preserving the back endothelial layer. Superficial ALK is employed to replace only the superficial layers. At the same time, deep ALK is utilized for more profound stromal damage, replacing the removed portion with healthy donor tissue [6]. Descemet’s stripping-only technique is suitable for mild-to-moderate cases of Fuchs’ dystrophy, involving the removal of central guttae without inserting new tissue. This approach allows healthy peripheral endothelial cells to migrate across the posterior cornea to the center, effectively restoring corneal clarity without needing donor tissue transplantation [7]. These innovative corneal transplantation techniques offer tailored solutions for different corneal conditions, enabling surgeons to customize treatments based on the specific needs and severity of each patient’s condition. Corneal transplantation techniques are shown in Figure 1.

The constraints of current treatments for corneal endothelial dysfunction encompass several challenges, including the scarcity of donor corneas, the intricate nature of surgical procedures, and the heightened risk of graft failure associated with traditional corneal transplantation methods [8]. Moreover, immune rejection and complications related to cell culture present substantial hurdles to the success of corneal endothelial cell therapy, necessitating further research to establish robust identification of functional corneal endothelial cells and enhance the therapy’s safety and efficacy [9]. Furthermore, the demand for highly specialized infrastructure, lifelong postoperative care, and the limited accessibility to treatment due to cost constraints and the scarcity of donor tissue exacerbate the difficulties encountered in managing corneal endothelial diseases [9]. These limitations underscore the urgent need for developing new treatment modalities capable of surmounting these challenges and offering more effective and accessible solutions for patients grappling with corneal endothelial dysfunction.

Need for Alternative Therapeutic Approaches

In corneal endothelial dysfunction, alternative therapeutic approaches are pivotal for addressing limitations and enhancing treatment outcomes. Emerging innovations such as corneal endothelial cell therapy, regenerative medicine techniques, and gene therapy modalities present promising alternatives to traditional treatments such as endothelial keratoplasty [10-12]. These innovative approaches are designed to overcome challenges such as the scarcity of donor tissue, the risks associated with graft rejection, and the need for specialized expertise inherent in conventional transplantations [11]. By focusing on cell-based therapies, regenerative medicine strategies, and gene editing techniques such as CRISPR, researchers are paving the way for more effective and targeted interventions in treating corneal endothelial diseases [12]. Furthermore, advancements in growth factor injections and novel pharmaceutical agents such as TTHX1114 growth factor by Trefoil Therapeutics exemplify the potential for non-invasive treatments that could significantly benefit patients with corneal endothelial diseases [10]. These alternative therapeutic modalities offer novel avenues for treatment and promise to improve patient outcomes by providing safer, more efficient, and potentially curative options for individuals suffering from corneal endothelial dysfunction.
