Materials and Methods
A spot survey was carried out on ophthalmologists attending the annual conference of the All India Ophthalmological Society at Bhubaneshwar in January 2005 using a structured 34-point questionnaire answered at-the-venue (Appendix 1).
Roughly 15% of the attending ophthalmologists (n=300) were randomly given the questionnaire on the spot.
The results were evaluated using t-test and X2 tests.
