Synopsis:

Basic knowledges about refraction of the eye. Techniques of the subjective refraction perform testing frame or the phoropter.Techniques of the examination near vision.

Requirements:

Credit requirements:

1. Attendance at class, two absences allowed

2. Practical verification of subjective refraction

3. Completion of 6 protocols during the exercises

Exam requirements:

1. Written part - verification of the most important knowledge. The condition for admission to the oral part is a 50% success rate in the test.

2. Oral part - the student draws one triplet of questions from a known combination of questions.

Syllabus of lectures:

1. Optotypes, examination distance, history, observation, symptoms, refraction chart, examination procedure

2. Examination rim, vertex distance, pupillary distance, rim vs. foropter, rules of monocular refraction

3. Advantages and disadvantages of objective refraction, use of objective refraction values

4. Determination and procedure for measuring hypermetropia, best sphere, haze

5. Detection and measurement procedure of myopia, best sphere

6. Jackson's cylinder - determining the axis of astigmatism, determining the magnitude of astigmatism

7 .Alternative methods of measuring astigmatism

8. Sphere check, fine spherical correction, red-green monocular test

9. Accommodative balancing - Humphriss test, bichromatic polarization tests, line test

10. Near point of accommodation, accommodative width

11. Basics of near and intermediate refraction, addition

12. Classification of ocular dominance, tests for ocular dominance

13. Infinity check, tolerance test, recording values

14. Case reports

Syllabus of tutorials:

1. History, observation, symptoms, presentation of optotypes, all

2. Examination rim, pupillary distance, vertex distance, examination distance, refraction card

3. Detection and measurement of hypermetropia, haze, best sphere

4. Detection and measurement of myopia, best sphere

5. Working with Jackson's cylinder

6. Determining the axis and magnitude of astigmatism using Jackson's crossed cylinder

7. Examination of astigmatism - the fogging method

8. Sphere check, fine spherical correction, CZ monocular test

9. Humphriss method of accommodative balance

10. Near point of accommodation, accommodative width

11. Examination of refraction at near and intermediate distance, addition

12. Tests for ocular dominance, use of ocular dominance

13. Infinity check, tolerance test, recording of values

14. Final refraction
