KERAVISION (KERA)
10/25/99

On Saturday, October 23nd, 1999, at the meeting of the International Society of Refractive
Surgeons (ISRS), a panel was conducted called:

                                                            
On Trial:  LASIK VS. PRK VS. ICRS For Low Myopia (-0.5 to -4D)

Afterwards, a poll was conducted among the attendees.
 
                                            


There may have been about 500 people listening to the debate, although it not clear how many 
took part in the survey. After presentations were made, the physicians in the audience
were asked several questions based on what they are currently doing in their practice
and what they may do in the future.

    myopia?

5.) Based on the presentations, which do you believe is the best treatment for low myopia?
