Evolution of eye banking in India - A review

Corneal blindness ranks third among the causes of blindness worldwide, after cataract and glaucoma. Corneal transplantation offers us a means to address this, and is currently the most commonly performed transplantation procedure worldwide - restoring the gift of sight to many an eye. Eye banks play a very important role in these procedures. India was quick to develop its own eye bank in 1945 soon after the launch of world's first eye bank in 1944. The evolution over the past six decades has been tremendous, placing India on the top, with one of the largest eye-banking system in the world. As of 2023, around 740 members are registered under the Eye Bank Association of India. The highest-ever collection of 71,700 donor eyes was achieved in 2017-2018. The overall tissue utilisation rate ranged between 22 - 28 % for voluntary donations and 50% for hospital-based corneal retrieval programs. Though India has an excellent infrastructure and readiness for corneal transplantation surgery, the need of the hour is to create a strong and independent nodal system. It shall take care of the logistics and factor in technological advances - surgical and otherwise. Public awareness, a national corneal grid, and reducing the red-tape barriers, shall improve availability of grafts nationwide. This review aims to detail the evolution of eye banking in India, to provide a comprehensive understanding, and help the stakeholders focus on the road ahead to attain our targets faster.

Optometry students' perspective on optometry in suburban Western India: A qualitative study

PURPOSE

Optometry has been an established profession in India for 60 years. Despite this, students who choose this course may have misconceptions and unrealistic expectations about the profession. The goal of this study is to understand the perceptions about optometry among optometry students, prior to and during their studies.

METHODS

A snap-shot narrative qualitative study using a semi-structured open-ended questionnaire was designed to understand the perception of optometry. Optometry students and educators from three suburban colleges were invited to participate. Forty-one participants took part in 24 in-depth interviews and 5 focus groups; of those 32 were undergraduate optometry students and 9 were optometry educators. Interviews and focus groups were audio-recorded, transcribed, coded, and analyzed.

RESULTS

Three major themes emerged: retrospective perception of optometry, current perception and strategies to improve awareness level. All the participants mentioned that there was a considerable lack of awareness about optometry in society. None of the students stated that they chose optometry as their first choice of professional education. Most students expressed that they were provided with ample exposure during the curriculum to understand the scope of optometry. Various strategies were recommended to improve the level of awareness of optometry.

CONCLUSIONS

The current study highlights the lack of awareness and knowledge of optometry among the students while enrolling in the course. Knowledge about the scope of optometry practice among optometry students improved after extensive education and clinical exposure. Improving the awareness level of the profession will improve the quality of students entering the profession.

Imagining eye care in India (2018 Lalit Prakash Agarwal lecture)

India has done well in eye care delivery by recognizing visual impairment and blindness as a major medical challenge. Major contributions have come from ophthalmologists (mass cataract surgery in the early 1900s; major participation of non-government organizations), policy makers (National Program for Control of Blindness and Visual Impairment 1976; systematic development under the World Bank assisted India Cataract Project, 1995–2002), and the industry (manufacturing of affordable surgical instruments and medicines). Although the country could boast of higher cataract surgical coverage and near-total elimination of trachoma, there is increasing prevalence of diabetic retinopathy and undetected glaucoma. India is in the crossroad of adherence to old successful models of service delivery and adoption of new innovative methods of teaching and training, manpower development and skill-based training, relevant medical research and product development. In the absence of these new approaches, the initial gains in eye care could not be furthered in India. A new approach, that will combine the best of the “old” tradition of empathy and the “new” technology of analytics, is required to imagine the future of eye care in India.

The injection of DisCoVisc into the anterior chamber improved corneal preservation and transplantation for cornea blind patients

PURPOSE

In this study, we aimed to provide a new method of corneal preservation by injecting DisCoVisc into the anterior chamber of eyeballs and evaluate its efficiency for corneal transplantation.

METHODS

Three pairs of eyeballs (n=6) were preserved by DisCoVisc viscoelastic agent, and the corneas were stored for 1 to 6 days. Then, the structure and morphology of cornea were analyzed by hematoxylin-eosin (H&E) staining, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, and transmission electron microscopy (TEM). The corneas preserved by this method were transplanted into 15 patients with corneal disease and the efficacy was assessed.

RESULTS

Epithelial cells and endothelial cells were intact and a normal morphology was preserved in both fresh corneas and corneas stored for 1-6 days by DisCoVisc viscoelastic agent. Corneal endothelial cells did not appear apoptosis in fresh corneas and corneas stored for 1-3 days, whereas a few apoptosis positive cells were shown on the 4^th day. The results of TEM showed that all corneas had active corneal endothelial cells with normal nuclei and homogenous nucleoplasm. Desmosomes and hemidesmosomes were closely connected. Mild nuclear pyknosis and autophagic cell death were only found from the 6^th day, and mitochondria appeared a little bubble from the 5^th day. Visual acuity in 11 of the 15 patients receiving transplantation of the preserved corneas was improved by more than 0.5. Average corneal endothelial cell counts, areas of corneal endothelial cells, and CV% of average area were not affected during the 6-month follow-up. Compared to the values obtained one-month postoperatively, the values of corneal thickness were significantly reduced in the three-month and six-month periods.

CONCLUSIONS

Corneal preservation technology with the injection of DisCoVisc viscoelastic agent may effectively extend the preservation time of corneas for five days, which could be used for patients as penetrating keratoplasty surgery.
