Proper understanding of the optical system of the eye and the principles of clinical examination are important in evaluating visual functions and correcting refractive anomalies and/or vision loss. If we use equipment or methods without understanding which physical principles and procedures underly their use, we may introduce sizable errors into the outcomes of cataract and refractive surgeries. However, if we correctly understand how the technology and procedures interface with the optical system of the eye and the principle of optics, it is easy to enhance the accuracy and predictability not only of measurement, but also of surgical outcome. For more accurate correction, refractive and cataract surgeries should be based on proper understanding of optical properties of the eye. This paper reviews a number of problems associated with pre- and post-operative examinations in recent cataract and refractive surgeries; many approaches to overcoming these problems.
