The story
In 1998, Lasik Vision Corporation was the first laser vision correction provider in North America to offer "affordable, value-pricing" and to promote it with direct-to-consumer advertising. At the time, this was a new approach for a medical services company and allowed it to capitalize on a larger mass appeal for the procedure. Wallerstein was the National Medical Director of LASIK Vision Corporation and oversaw medical standardization, and Cohen was the National Director of Professional Affairs and oversaw physician recruitment and training. By 2000, Lasik Vision Corporation, a publicly traded corporation, became the largest laser vision company in the world, as measured by procedure volume.
However, soon after its bankruptcy in 2001, Cohen and Wallerstein left LASIK Vision to implement a similar medical model in a group of privately owned facilities. These centres operate under the name LASIK MD. LASIK MD subsequently acquired the majority of the former Lasik Vision facilities in bankruptcy proceedings in Canada.
