Decoding Your Astigmatic Prescription made easy
WELCOME TO INSIGHT OPTHALAMOLOGY !!
The refractive power of the astigmatic eye varies in different meridians. The image is formed as a Sturm's conoid.If the principal meridians are at 90° to each other, this is called regular astigmatism. If the principal meridians are at 90° to each other but do not lie at or near 90° and 180°, the term oblique astigmatism is used. If the principal meridians are not at 90° to each other, this is called irregular astigmatism and cannot be corrected by
spectacles.
Compound hypermetropic astigmatism - rays in all meridians come to a focus
behind the retina
Simple hypermetropic astigmatism - rays in one meridian focus on the retina,
the other focus lies behind the retina.
Mixed astigmatism - one line focus lies in front of the retina,
the other behind the retina.
Simple myopic astigmatism - one line focus lies on the retina, the other
focus lies in front of the retina.
The video gives tips and tricks on how to read and astigmatic prescription and how to correctly understand an astigmatic prescription.

-6 SPH, +2 CYL at 90º Correction power needed for vertical is -6 Correction power needed for horizontal is -4 Same type of correction on both, so it's Compound Astigmatism And the correction is -, so the defect is +, this eye is Myopic And there is more power vertically than horizontally, so overall it's: WTR Compound Myopic Astigmatism Something the video does not cover: how are prescriptions of bioblique astigmatism written and decoded?
