Abstract

The proper uses of ophthalmic and optical instruments play an important role in diagnosis and treatment of eye diseases. Precision and accuracy assessment are the major indicator for evaluation of instruments. The former consists of repeatability and reproducibility， while the agreement assessment decides its accuracy. There are so many studies focused on this field due to the rapid development of new techniques and instruments， followed by the arising of problems in method selection. This article introduces the main methods of precision and accuracy assessment. And we also provide the ideas of proper method selection in clinical practice and research with examples. Moreover， we discussed the influence of analytic approach with one eye or two， as well as sample size calculation.
