A/An radial keratotomy is a surgical procedure to correct myopia by making incisions in the cornea to cause it to flatten.
Myopia or nearsightedness is treated with a type of refractive surgery called radial keratotomy (RK). RK, which was invented in Russia in the 1970s by Svyatoslav Fyodorov, a Russian ophthalmologist, was the first refractive surgical technique to become popular in North America.
In an RK surgery, the cornea is flattened by use of a series of small, deep incisions. As myopia is frequently caused by an excessive corneal curvature, this surgery will ideally aid to lessen nearsightedness and astigmatism.

How do nutritionist formulate health promoting guidelines to public?
Traditional education programs need to be updated in order to better the knowledge of nutrition specialists and their abilities to instruct a wide range of audiences to base their eating habits on dietary guidelines.
For instance, in addition to emphasizing the scientific foundation of the recommendations, courses must also highlight the social and behavioral components of promoting dietary changes. Curriculums should also include pertinent information from the agriculture and food sciences. This necessitates a careful balance. The practical aspects of nutrition and dietary change may be overlooked if the scientific underpinnings are given too much weight.
The rising body of research on diet has to be incorporated into programs by public health and other community-based nutrition specialists that actively promote health among target populations. Increase the degree of understanding of food, nutrition, and the connections between diet and health among all medical professionals. Establish a distinct program with ultimate responsibility for planning and developing a research and education agenda in human nutrition within the faculty of each health-care professional school. Create a program at the Public Health Service to aid in faculty members' nutrition education. For each of the accredited graduate programs in the healthcare professions, the objective should be to have at least one nutrition faculty member per health-care professional school.
