Corrective and preventive actions (CAPAs) in eye bank.

This case series highlights the challenges in eye banking and the importance of a quality assurance program. Three cases triggered corrective and preventive actions (CAPAs) to improve the processes. Case 1 emphasized training to prevent retrieval failures. Case 2 stressed the need for blood samples and comprehensive documentation. In Case 3, mishandling led to policy revisions and staff training. CAPA involved identifying concerns, root cause analysis, action plans, implementation, checks, and closure. Errors can occur in man, machinery, process, and policies. Continuous CAPA ensures continuous quality improvement and safe corneal tissue transplantation, benefiting patients in need.

P25-A123†Indo - German GIZ collaboration - impact and way forward in global eye banking.

PURPOSE: Geographical imbalance in cornea supply is a key feature of global eye banking. Most countries of South Asia particularly India suffer from donor cornea shortage which limits the number of keratoplasties, thereby aggravating the already high burden of removable blindness. The purpose of the project is to identify and cross-pollinate best practices from two leading eye banking institutions in India and Germany, and thereby improve service delivery of both systems. The project is supported by the GIZ Hospital Partnerships funding program on behalf of the Federal Ministry for Economic Cooperation and Development (BMZ) with a co-financing by the Else Kröner-Fresenius Foundation (EKFS). It started in 2021 and will last upto 2023. METHODS: A joint expert group from both organisations conducted a series of workshops to identify the areas of intervention and specific practices to be introduced at the Indian partner's region. The overall increase in cornea collections and transplants, documented systemic improvement measures and research output were defined as the key outcomes. RESULTS: Interim results are presented here. Two interventions identified were expansion of catchment area of cornea collection in India, and improved information management system to monitor the progress and efficiency of the collection centres. Under the former intervention, the hub-and-spoke model from the German partner was introduced to the most populous state of India through establishment of two new cornea collection centres (spokes) for Hospital based Cornea collections. In six months these centres have supplied 79 donor corneas leading to 63 transplants at the hub. Under the latter intervention, the specifications of a baseline data capture and operations management system which can be used in low resource settings are being developed. CONCLUSION: The initiative has shown how best practice from one geography can be adapted and successfully implemented in another geography , Furthermore, the public knowledge resources created in the project can be used by other eye banks to advance eye banking in their respective countries.

Effect of transfer of donor corneal tissue from McCarey-Kaufmann medium to Optisol-GS on corneal endothelium.

PURPOSE: The purpose of this study is to evaluate the effect of transfer of donor corneal tissue from McCarey-Kaufmann (MK) medium to Optisol-GS on corneal endothelium. METHODS: This was a prospective, randomized comparative study. Twenty paired human donor corneal tissues of optical quality were retrieved. One tissue of the pair was preserved in Optisol-GS preservative medium (Group A) and other tissue of the pair in MK medium (Group B) at the time of corneoscleral disc excision. Within 12 h of retrieval, each cornea was evaluated using slit-lamp biomicroscopic examination and specular microscopic analysis. Group B corneas were transferred to Optisol-GS medium within 48-53 h of retrieval. Specular analysis of the paired corneas was repeated 3 h after transferring to Optisol-GS. On day 7 of storage, specular analysis of both the tissues was repeated. RESULTS: The average age of the donor at the time of death was 29 years (16-68 years). The reduction in endothelial cell count, from baseline, in Groups A and B was 5.5% and 5.8% (P = 0.938) on the 3rd day and 8.2% and 12.6% (P = 0.025) on the 7th day, respectively, postretrieval. The coefficient of variation (CV) increased by 36% (P = 0.021) and hexagonality reduced by 19% (P = 0.007) on day 7. All tissues retained an endothelial cell density higher than the accepted critical level for penetrating keratoplasty. CONCLUSION: Significant endothelial cell loss was noted while transferring tissues from one medium to another, necessitating the need for reevaluation of transferred tissues before utilization.
