A survey of 500 ophthalmologists in the Northeast United States on the subject of ophthalmic assistants yielded 332 answers which could be used. They indicated that 23% of ophthalmologists would hire an ophthalmic assistant immediately if they did not already have one, 32% would probably hire one, while an additional 29% would give careful consideration to the idea. On the other hand, 8% would definitely not hire one.
