Advancing keratoconus treatment: the impact of bioengineered porcine constructs on corneal reshaping and visual acuity

There has been a significant development in the field of ophthalmology that holds promise for individuals grappling with keratoconus—a condition affecting millions worldwide. The recent study on the double crosslinked (BPCDX) bioengineered porcine construct presents a paradigm shift in keratoconus treatment, offering hope to those with visual impairments [1]. Keratoconus, characterized by corneal thinning and steepening, significantly impacts visual acuity. Traditional treatments, including rigid gas permeable contact lenses and corneal transplantation, have been effective, but the introduction of BPCDX opens new avenues. The pilot feasibility study conducted in India and Iran indicated that this cell-free, minimally invasive approach effectively reshaped the corneal stroma, showing promising results. [2]. Additionally, the study’s findings showcased notable improvements in corneal thickness, maximum keratometry, and visual acuity [1]. Remarkably, all initially blind subjects achieved a mean best-corrected vision of 20/36, highlighting the potential of BPCDX in restoring sight. The longevity of the implants, with a shelf life of up to two years, addresses challenges associated with donor dependency and tissue banking infrastructure [3]. However, the introduction of porcine-derived implants raises concerns in Muslim-majority countries where religious beliefs and dietary restrictions may influence acceptance. Cultural norms and interpretations of religious laws play a pivotal role, and stakeholders must navigate sensitivities surrounding porcine implants [4]. Acknowledging these considerations is crucial for widespread acceptance and implementation. Furthermore, the potential cost-effectiveness of bioengineered implants, derived from pig skin byproducts, could make this solution accessible to individuals in third-world countries, like Pakistan [5]. The ability to store these implants for an extended period simplifies logistics and facilitates distribution to those most in need, addressing the increasing prevalence of keratoconus in the region [6]. The study’s innovative surgical approach, utilizing a laser incision rather than traditional sewing, represents a step towards safer and simpler procedures [6]. The reduced reliance on immunosuppressive drugs post-surgery is a significant advancement, enhancing patient recovery and potentially lowering healthcare costs [6]. Moreover, a consideration that might prove beneficial in this situation is that in Islam, necessities overrule prohibitions. The Islamic Institute of Australia resonated these findings in stating that followers of the Muslim faith can gain benefit from porcine material only in extreme circumstances in which life and death are involved and in which no other alternative is available. Hence it is very important to define necessity in such situations. Moreover, it also incumbent to involve the patient in the decision making process. Depending upon the wishes and desires of the patient, the doctor should consider appropriate alternatives whenever possible [7,8,9]. In conclusion, the BPCDX study offers a notable approach for keratoconus patients globally, with implications for both advanced medical settings and resource-constrained regions [1]. The new model improves treatment outcomes and introduces a cost-effective and logistically feasible option for countries facing challenges in corneal transplantation [5]. As we acknowledge this advancement in medical science, it is crucial to engage in open discussions about cultural and religious sensitivities surrounding porcine-derived implants. Collaborative efforts between the medical community, religious leaders, and communities themselves will be instrumental in ensuring the widespread acceptance and adoption of this treatment.
