Can I Have Laser Eye Surgery if I Have Prism?

If you have a “squint” or strabismus, you may be familiar with an optical element called a ‘prism’.

Prisms are built into glasses to enhance visual comfort in people who have strabismus, particularly if you experience double vision and symptoms such as eye strain and headaches.

Somewhat a unique advantages of glasses, prisms work by moving the image of an object either vertically or horizontally, depending on the direction and the power of the lens, and therefore redirecting the eye’s alignment.

This means that Laser Eye Surgery, as it is chiefly concerned with correcting refractive errors such as shortsightedness and longsightedness and does not realign the eyes, cannot replicate the action of prism glasses.

That’s the bad news. However, there’s also some good news. Despite being unable to rid you of the need for prism glasses, the chances are if you have strabismus and use prisms, you are still suitable for Laser Eye Surgery.

Having Laser Eye Surgery if you use prisms

In the video below, expert Laser Eye Surgeon Mr Glenn Carp explains how you can have the treatment if you use prisms, although you may still need prism glasses if you have double vision with contact lenses or without the prism in your glasses.

Mr Carp explains how Laser Eye Surgery is able to deal with refractive error but not the prism effect, and gives a few options for dealing with this.

Laser Eye Surgery has a lot to offer people who have vision problems. Therefore, as Mr Carp explains, Laser Eye Surgery may still be able to help you eradicate refractive errors, despite not being able to affect eye alignment.

This is unfortunate as it means you may still require glasses after Laser Eye Surgery in order to correct the prism effect. However, if this is the case for you, there is the option of undergoing muscle surgery around the eye to correct the strabismus, thereby negating the effect or the need for a prism.

In this way, Laser Eye Surgery can be used in combination with muscle surgery to be a viable and effective solution to strabismus and prisms.

Of course, the only way to know for sure if you are suitable for Laser Eye Surgery and what your options are is to speak with the experts and have a thorough and detailed assessment.
