Course content
Lecture Lecutres provides theoretical and practical preparation to the realisation of the practical-experimental activities in the frame of practical tutorial and seminars INTRODUCTION Refraction - development and changes of refraction during life SPHERICAL AMMETROPIA Myopia (classification, symptoms, aetiology, correction) Hypermetropia (classification, symptoms, aetiology, correction) - influence of correction on the vision Astimgatismus (TABO, classification, symptoms, aetiology, correction) EYE EXAMINATION BY OPTOMETRISTS Basics steps of the routine examination of the vision functions PRACTICAL METHODS OF REFRACTION MEASUREMENT Objective refraction (retinoscopy, refractometry, keratometry; interpretation of results) - basics steps of subjective refraction measurement (best sphere and fine correction, astigmatismus, binocular refraction) Practical training Small groups (pairs) on separate refraction lines. Each group is separately monitored. Monitoring of output competencies using recorging form. Observation of the red fundus reflex, training of direct ophthalmoscopy; demonstration of the fundus observing by a nonmydriatic camera Retinoscopy: Spot and strip retinoscopy - spherical refractive error measurement Strip retinoscopy - determination of the main meridians of astigmatismus,measurement of the relevant refractive error Monocular examination of refractive error Measurement of PD Individual adjustment of the trial frame Best sphere - maximal "+" and minimal "-" method Best sphere - monocular fogging method Fine spherical adjustment (duochrome test, max. +/min -) Examination of astigmatismus - crosscylinder method Examination of astigmatismus - clock-dial and fogging method Complete monocular examination of refraction Binocular examination of refractive error: Binocular refractive balancing - Humphriss method Binocular rafractive balancing - double-row test Binocular refractive balancing - alternative tests Binocular refraction by polarised optotypes Fine binocular spehrical correction, visual comfort evaluation, correction checking Seminar Individual consultation and practical training. Take part on the training of students of higher years.

Learning outcomes
To familiarize with refraction errors and their management. The next aim is to practical training in the areas of monocular vision examination.
Knowledge and practical skills. Student should: to define the refractive errors, to describe their symptoms, aetiology, classification, possibilities of correction; to understand influence of correction on the vision, accommodation and vergence system, to explain principles of measurement of refraction; to measure visual acuity; to realise practically the investigation of monocular and binocular refraction (in adults); to observe red reflex, to do retinoscopy; to measure reading add; to understand basics of refraction surgery, to be able to explain the basic method of laser refractive surgery (PRK, LASIK), to know the risks of laser refractive surgery.
No prior requirements.

Assessment methods and criteria
Student performance

Active attendance in the exercise lessons, skills within the scope of the course topics.
