“…6 NEB is in a favorable location, which is an advantage for shorter tissue excision and preservation time. In our study, average DPT was 5.7 hrs (Figure 2), which is similar to that reported by Sharma et al 5 Other reports mentioned averageDPT of 2.8 to 3.9 hrs. 3,7,9 Cunningham et al 10 mentioned longer DPT of 18.5 hrs.…”

“…The motivated collection of cornea in eye banks in various parts of India ranges from 69 to 86% which is similar to our studies. [3][4][5] Some eye banks in India rely mostly on home deaths with collections from 71 to 75.2% of the tissues. [6][7][8] In our study, all HCRP donors (87.7%) were within 10 kilometers of the eye bank (Table 1) unlike in the study of Desar et al, where the distance to travel to get corneas was more than 60 km in one third of the donors.…”

Purpose: Corneal problems is one of the major causes of blindness in developing countries like Nepal. This study intended to analyze donor and tissue profile of Nepal Eye Bank (NEB). Material and Methods: This was a cross-sectional descriptive type study. Data of corneal tissues collected by NEB from January 2015 to December 2016 were used in the study. Data collected were demographic profile, cause of death, type of corneal donation (whether voluntary or motivated), quality and utilization of tissues. A comparison was made between voluntary and motivated donors. Results: 1244 corneal tissues were retrieved from 639 donors. Mean age of donors was 49.4 years. 57.7% of the donors were male. There were almost equal number of donor deaths due to cardiovascular disease, 27.2%, and respiratory disease, 26.7%, followed by hanging, 17.8%. Majority of donors were motivated (n = 561, 87.7%). Mean death to preservation time was 5.79 hours (hrs). Of the harvested corneas, 1040 (83.6.%) were suitable for transplant with a mean endothelial cell count of 2850 ± 520 cells/mm 2 ; 16.4% were of poor tissue quality and 2.7% were seropositive. 76.2% of total tissues were of optical quality. Utilization rate of transplantable tissues was 97%. Tissues from motivated donors were significantly "younger" (p=0.0001), had better endothelial count (p=0.0001), and were of better quality (p=0.026) than those from voluntary donors. Conclusion: Motivated eye donation is a major and effective source of cornea collection in the eye bank under study with "younger" and better quality corneas compared to voluntary donors.

“…Our study showed younger donors were more from hospital donations. 4 A study by N Sharma et al reported in a HCRP-based study, which had a higher proportion of donors in younger age (H=81.6% vs. V=21%,) (H=Hospital, R=Residence). 9 A study done by Jonathan H. Lass et al showed that the corneas received from a donor 66 to 75 years old experienced cell loss of 79% at 10 yrs.…”

BACKGROUND The voluntary eye donation is still the most popular methods of eye donation in our country. Since last three decades, the voluntary eye donation is promoted by a number of NGOs and Government of India. The meaning of voluntary eye donation is that an individual has prior knowledge about eye donation and also has the contact number of the eye bank. When they come across any death in their community, they will contact the eye bank for eye donation. As per Eye Bank Association of India, the incidence of total blindness is 8.9 million and 1% of this is corneal blindness. Each year, 25,000 to 30,000/new corneal blind patients are added. The voluntary eye donation is not sufficient in providing transplantable corneas to the corneal blind. As our concentration is mainly on voluntary eye collections, this is one of the main reasons that we are unable reach our target of sight restoration in the management of corneal blindness. In this study, we have analysed the voluntary eye donations procured from residence and hospital. The aim of the study is to compare corneas procured by hospital eye donations and residence eye donations to look into all factors that contribute to a transplantable cornea. MATERIALS AND METHODS The donor corneas retrieved from the year 2005-2010 were analysed. The hospital eye donations and residential eye donations were divided into two study groups. The factors analysed were number of corneas collected, donor age and gender, serology test result, death to preservation time (DPT), optical grade cornea, utilisation of corneas for transplantation and role of pledging in eye donation. Study Type-Retrospective study. Study Done-At Lions International Eye Bank, Bangalore. RESULTS The total number of donor eyes collected from the year 2005-2010 were 7362 of which residence collections was 50.73% and hospital collections was 49.26%. The 5-year period between from 2005 to 2010 in spite of not conducting a Hospital Cornea Retrieval Program (HCRP), we still had received a number of young corneas from hospitals. The transplantable grade corneas were 26.33% in hospital eye donations and 16.26% at residence. The death to enucleation time was less in hospital deaths when compared to that of residence collection.

Comparison of Hospital Cornea Retrieval and Voluntary Eye Donation Program in Eye Banking

Abstract: Most corneas retrieved through HCRP were of optical grade quality and efforts should be focused on HCRP to reduce the demand-supply deficit in cornea transplantation.
