Activity Description: Through the use of a multi-tiered pricing model (in which higher revenues earned from wealthier patients cross-subsidize low-income patients), ASEMBIS of Costa Rica has created a financially self-sustaining network of eye care clinics that offer services from basic eye examinations to sophisticated surgical procedures, at a 40-70% discount from the market rate.

ASEMBIS's integrated network includes non-traditional health professionals for vision testing and preventive care, cost-efficient and high-volume clinics, and mobile rural clinics; in all treating over 350,000 patients in 2004.
