If you are wondering how to correct an astigmatism, the treatment options are outlined below. To restore a patient’s vision, a change needs to be made so that the light can be focused properly once more. This can be done either by using external corrective lenses (glasses or contact lenses) or through surgery (laser eye surgery or lens implants with toric – astigmatism correcting intraocular lenses).

This is a surgical procedure to insert a lens into the eye – known as an intraocular lens (IOL). The IOL will correct the astigmatism and help the patient regain superior vision.

The above steel beam span calculator is a versatile structural engineering tool used to calculate the bending moment in a aluminium, wood or steel beam. It can also be used as an i beam load capacity calculator by using it as a bending stress or shear stress calculator. It is able to accommodate up to 2 different concentrated point loads, 2 distributed loads and 2 moments. The distributed loads can be arranged so that they are uniformly distributed loads (UDL), triangular distributed loads or trapezoidal distributed loads. All loads and moments can be of both upwards or downward direction in magnitude, which should be able to account for most common beam analysis situations. Bending Moment and Shear Force calculations may take up to 10 seconds to appear and please note you will be directed to a new page with the reactions, shear force diagram and bending moment diagram of the beam.

Often astigmatism is hereditary. However, it also occurs when eye surgery has left scars on the cornea or if you have sustained an injury to your eye. Conditions such as keratoconus that affect the shape of the cornea will also result in astigmatism

It occurs when a shaped cornea or lens stops the eye from focusing light properly. In this article we will explain how to correct astigmatism by ensuring that light entering the eye is properly focused.

OCL Vision offers customised flap creation in laser eye surgery, helping you achieve optimal results from your procedure.

Patients undergoing laser eye surgery report better vision as early as 24 hours following the procedure, which takes around 15 minutes total for both eyes. One eye can be corrected immediately after the other.

Contrary to what you may have heard, astigmatism can be treated with laser eye surgery. This is a quick and non-invasive procedure that uses a laser to change the shape of the cornea, thereby altering the path of the light that enters the eye. The laser procedure will also correct your long- or short-sightedness if this is present.

Astigmatic corneas can be rugby-ball shaped – this is called regular astigmatism and is the most common kind. Alternatively you may have a cornea which curves in different directions and has some areas thicker than others – this is called irregular astigmatism and is much rarer. Usually, astigmatism is present from birth, and is identified during routine eye tests.

A patient with astigmatism experiences a refractive error, caused by the shape of the cornea or the lens. Typically, their eyes will be shaped more like an oval than a perfect sphere. This means that their vision will be blurred or distorted because the light rays are not coming together and focusing in the right place as two points of focus exist.

In normal vision, the cornea and the lens work together to refract the light that enters the eye through the pupil. The eye is shaped so that the refraction, or bending of the light, happens in exactly the right way to focus the light perfectly and produce an accurate image on the retina.

If you have astigmatism you may have trouble reading, particularly if the print is small. You may also squint and suffer from headaches and fatigue. While some cases of astigmatism are very mild and need no treatment, others are more severe and will require treatment to correct the patient’s vision.

More invasive than laser eye surgery, clear lens extraction can nevertheless be a good option for patients who are undergoing cataract surgery at the same time, or for those who are not eligible for laser eye surgery.

One of the most powerful functions is using it as a beam deflection calculator (or beam displacement calculator). This can be as a simply supported beam or to find the deflection of a cantilever beam. Being able to add section shapes and materials, this makes it useful as a wood beam calculator or as a steel beam calculator for lvl beam or i beam design. For now, this functionality is available in SkyCiv Beam.
