title: Current developments in measurement of corneal topography.
abstract: Significant developments in the measurement of corneal topography have taken place since the early Placido devices. These developments have arisen as a result of two key factors: increased computer processing power and also improved algorithms that are capable of deriving corneal shape without making any fundamental assumptions. These developments are reviewed and attention is drawn to some of the key areas where current topographical devices are somewhat limited.
