Mopane 2006 Conference Abstracts


Held at the Mopani Camp, Kruger National Park, Limpopo Province, South Africa, August 6 - 9, 2006

Excerpt taken from the Conference Proceedings cover:

The International Organizing Committee, The Local Organizing Committee and the Optometric Science Research Group welcome you to Mopane 2006 and thank you for attending the conference. We hope you will find this conference very rewarding and will also enjoy sights and sounds of the Kruger National Park. About fifteen years ago, Professor WF Harris established the Optometric Science Research Group with the purpose of promoting the development of optometric research and science. Other early founding members included DJ Malan and Professor A Rubin. Since the OSRG was started several scientific papers (over 250) have been published in peer reviewed journals and more than fourteen postgraduate students have received masters and doctoral degrees. In 1996 the first Mopane Conference was held at the same venue and the theme was Refraction and Keratometry: The Mathematics and Statistics. In 2003 the second Mopane Conference was again held at Mopani Camp and the theme was Astigmatism, Aberrations and Vision. Both were very successful conferences but we hope that Mopane 2006 will be even better. Enjoy your stay and we hope to see you again at the next Mopane Conference!
