Dr Nashua Naicker, lecturer and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, graduated on Thursday (April 18) with the degree Doctor of Philosophy in Health Professions Education.

A strong need to improve the general standing of optometry as a profession and to create lifelong learning opportunities for locally trained optometrists beyond what currently exists, is what led Dr Nashua Naicker to pursue a PhD in this field.

Dr Naicker, lecturer, and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, says he feels an overwhelming sense of relief with a keen sense accomplishment by achieving what he set out to through persistence in the face of adversity.

He graduated on Thursday (18 April) at the Faculty of Health Sciences April graduation ceremony with the degree Doctor of Philosophy in Health Professions Education through the Division of Health Sciences Education. “I am pleased and hope to change the narrative on this new path as an accredited researcher from ‘how long are you going to take to finish?’ to ‘what have you learnt in this journey?’. We are far too focused on chasing a timeline rather than focusing on the contribution that one makes and the self-development in this journey of discovery,” says Dr Naicker. 

His supervisor was Prof Alvin J Munsamy from University of KwaZulu-Natal (UKZN) and co-supervisor Dr CB Written from the UFS.  

Need for educational expansion

His research was focused on establishing a framework for postgraduate programmes in specialty fields of optometry for South Africa. The investigation was carried out with practising optometrists as the primary stakeholders and with optometric academics as the custodians for education and training in the country.

“With an overwhelming need for educational expansion found in this investigation, a conceptual framework was proposed as the innovation to take the profession forward in South Africa. Improving patient care from being upskilled and receiving professional recognition for the additional competencies and proficiencies that would be gained, was the motivating factors identified by optometrists to consider further education and training,” says Dr Naicker.

According to him, being in the educational fraternity for almost two decades and as a former education committee member of the professional board of optometry, he was able to see where the shortcomings were in the profession which set him on this path to pursue this research. With most optometrists in clinical practice and no clinical postgraduate qualifications available except pure research-based qualifications in SA, Dr Naicker explains that this hindered optometrists’ professional trajectory and career path opportunities into various special interest areas. 

“By developing a framework for horizontal articulation pathways towards coursework postgraduate qualifications in various clinical specialty fields, this would be the contribution in addressing the educational gap that would guide higher education institutions in their programme development process. The beneficiaries of this expansion would not only be the health professionals but the patients who access optometric care from the optometrists who would have advanced skills and competencies to deliver comprehensive eye care services.”

Stayed motivated

Dr Naicker says the journey to his PhD was challenging from the outset as the country went into hard lockdown due the COVID-19 pandemic just five weeks after he registered for his PhD. Working on a PhD was not a priority at the time when your survival and that of your loved ones was uncertain as thousands of people fell victim to the coronavirus. Further to this, he continues, multiple changes to his supervisory team and the overhaul and revitalisation of the administration and management of the UFS Division of Health Sciences Education, also impacted his progress in his doctoral research at that time. He had felt despondent after a year of being registered when stability arrived with supervisory assistance that re-ignited his drive to pick up the slack and keep moving forward.

“The words ‘push through it’ were verbalised to me by a stranger I met in passing.  While chatting about research I found those three words to be so profound and with such depth that they resonated with my experience of facing adversity but remaining vigilant to preservere and not drop the baton in the race against time to conclude my research. Gaslighting yourself and questioning your potential to complete a PhD only compounds your procrastination which was all too apparent. The goal is to rise above the self-doubt, brush off the devil with the fork sitting on your shoulder and just ‘push through it’.”

Dr Naicker, who is currently supervising four master’s of optometry students in their research undertaking, as well as undergraduate research projects, says he is in the process of publishing the research manuscripts generated from his PhD and is also part of a task team with the professional Board of Optometry for setting up the board exams for foreign-qualified optometrists. He would also like to work on research involving educating the educators of visually impaired learners.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
