Abstract
The purpose of this editorial is to provide guidance to prospective authors conducting precision (repeatability and reproducibility) studies in terms of basic concepts, terminology, statistical methods, sample size considerations, study design, use of 1 eye or 2 eyes, and worked examples. A number of bodies in the scientific world have devised their own terminology and statistical recommendations, some of which are similar and others markedly different. An example is the International Organization for Standardization (ISO), an independent nongovernmental membership organization and the world's largest developer of voluntary International Standards.
ISO has published more than 20 500 International Standards covering almost every industry, including ophthalmology. Examples include standards relating to contact lenses, contact lens care products, intraocular lenses, intraocular implants, spectacle lenses, and ophthalmic instruments. The ISO standards might differ markedly even within ophthalmic instruments, an example being differing statistical methods for tonometry and topography.
The purpose of this editorial is to provide guidance to prospective authors conducting precision (repeatability and reproducibility) studies in terms of basic concepts, terminology, statistical methods, sample size considerations, study design, use of 1 eye or 2 eyes, and worked examples
