[Corneal graft activity in France (1990-2005): decreasing the gap between supply and demand].

OBJECTIVE
To evaluate changes in the balance between supply and demand for corneal grafts over the last 15 years in France in the light of the measures implemented and the 2005 national and regional audit.


MATERIALS AND METHODS
Corneal transplantation activities were estimated, mainly from a national prospective survey of ophthalmologists (1991-1994), annual surveys of ophthalmologists (1995-2000), tissue banks (1996-2005), and the national waiting list for surgery (since 2000).


RESULTS
In 2005, the main indicators available were consistent with a stabilization in the number of candidates added to the waiting list every year (4606 in 2005), accompanied by a large increase in the number of grafts procured (9264 in 2005). There was also a substantial increase in quality testing of these grafts, leading to a high rate of rejection (49.5% of the procured grafts). In addition, the number of grafts exported decreased to a very low level (213 in 2005). The percentage of malades registered on the waiting list who received grafts in the same year also increased (68.5% in 2005). Once the waiting list had been updated, 3016 malades remained on the list at the beginning of July 2006. The gap between supply and demand for corneal transplantation has therefore narrowed. Two actions made particularly large contributions to these changes: the creation in 2000 of 120 full-time staff positions in hospital coordination teams, which has had a major impact on procurement rates; and the organization of the tissue bank sector, making it possible to guarantee the quality and distribution of grafts.


CONCLUSION
Corneal procurement and transplantation activities seem to have reached equilibrium in France. A reliable estimation of demand, particularly at the regional level, has led the French agency in charge of tissue transplantation to modify the functioning of the national corneal transplant waiting list, with tissue banks now allowed access to declare transfers and the temporary registration of malades on the list to limit stagnation.
