Teach you to understand the computer optometry sheet

Whether it is amblyopia or myopia , Optometry is a necessary procedure
Next, I will teach you how to understand the optometry sheet .

At the top is the basic information , Including name, （name）, Gender （M/F）（male/female）, Date time （ This picture is 2012 year 7 month 29 Japan 12：05 Divide the printed optometry sheet , Usually in English .）, VD=12.00mm It refers to that the distance between the eyes of the mirror set by the computer optometry is 12mm.

The core area of the optometry sheet , There will be two sets of data , One group is the right eye <R> Diopter , The other group is left eye <L> Diopter ;

The right eye and the left eye have 3-4 Column （ This picture 4 Column ）、1-5 Different inspection results , The first three columns are respectively S( Sphericity , Namely myopia 、 Hyperopia )、C（ Astigmatism , That is, near scattered / Far scattered column specularity ）、A（ Astigmatism axis , That is, the direction of the non refractive meridian of the astigmatic prism ）. Remember that these three columns are spherical mirror degrees 、 Astigmatism and astigmatism axis , The fourth column has no column labels , be called “ credibility ”, That is, the value of inspection accuracy considered by the computer .

1~5 That's ok （ This picture shows the left and right eyes 4 That's ok ）, The first three lines do not carry “<>”, Indicates that the eye has been read 3 Secondary refraction data , Equivalent to testing 3 Infra light ; There is a line with “<>” Of , This line is called “ Computer suggested results ”. The computer thinks “<>” The result in is the correct optometry result .

No matter the sphericity or astigmatism , Numbers are preceded by symbols , Not “+” namely “-”. among “+” Represents hyperopia ,“-” Represents the nature of myopia .

PD Is the pupil distance , Is the distance between the centers of the pupils of both eyes . This is the parameter required for matching .

The computer optometry instrument used in this drawing is relatively high-end , With corneal curvature examination results , What you see R1、R2、AVE、CYL、mm、D、deg, Is to describe the radius of corneal base arc 、 Meridian refraction and other information , Not here , This is a popular science blog , Not a professional lecture hall , Better than more .

The bottom letter refers to the name of the instrument used for optometry （NIDEK ARK-510A）.

good , According to the explanation above , Interpret the patient's computer optometry results ：（ Here we only interpret the optometry results of the patient's right eye ）：
The first line is 675 Degree of myopia 、 union 50 Degree myopic astigmatism 、 Astigmatism axis 36 Degree axis , The confidence value is 9;
The second line is exactly the same as the first line ;
The third line is 650 Degree of myopia 、 union 50 Degree myopic astigmatism 、 Astigmatism axis 39 Degree axis , The confidence value is 9;
The fourth line shows the result of computer recommendation , yes 675 Degree of myopia 、 union 50 Degree myopic astigmatism 、 Astigmatism axis 36 Degree axis , credibility 9;
