AstigmatismusRezept

AstigmatismusRezept is a term used to describe the written prescription that specifies corrections for astigmatism. In ophthalmology and optometry, astigmatism is a refractive error caused by an irregular curvature of the cornea or lens, which can lead to blurred or distorted vision at various distances. The prescription records the optical powers needed to compensate for this irregularity and to align vision across meridians.

A typical AstigmatismusRezept includes a spherical power (Sph) and a cylindrical power (Cyl) plus an axis value that defines the orientation of the astigmatic correction. It may also include a Pupillary Distance (PD) for proper lens centration and, if presbyopia is present, an additional reading power (Add). The Cyl value indicates how much cylinder correction is required, while the Axis value (0–180 degrees) specifies the meridian of strongest curvature that is corrected.

Corrections may be provided as eyeglasses with toric lenses, toric contact lenses, or as part of refractive surgery planning. The chosen medium depends on patient needs, comfort, and ocular health. An AstigmatismusRezept is usually valid for a period determined by the clinician and may be updated after a follow-up examination.

Obtaining an AstigmatismusRezept involves a formal eye examination, refraction testing, and often keratometry or corneal topography to quantify astigmatism. Accurate measurements and patient feedback are essential to ensure proper lens alignment and visual acuity. The prescription may be adjusted over time as vision changes.
