WHY CHOOSE US?

Astigmatism, what are my options?

Astigmatism is an eye condition that affects the clarity of vision making it more difficult to focus on objects at both near and far distances.

Astigmatism

What is it?

In a normal eye, the cornea is round like a soccer ball. In astigmatism, it usually looks more like an Aussie rules football since the curve of the cornea is not the same in the horizontal and vertical plane. This distortion causes the incoming light rays to focus at multiple points in front or behind the retina, which results in blurred vision.

Although astigmatism can exist as a problem by itself, it usually occurs together with myopic (short sight) and hyperopic (long sight) prescriptions.

Signs and symptoms of astigmatism may go unnoticed, but more significant degrees of astigmatism will cause symptoms such as: blurred vision in the distance and/or when reading, squinting, fatigue and headaches.

Astigmatism

Treatment

The astigmatism treatment depends on the degree of severity but commonly include glasses or toric contact lenses that help focus the light properly. However, since laser eye correction gently changes the curve of the cornea, it now provides outstanding results for anyone with a suitable astigmatic prescription.

Astigmatism Treatment and laser eye surgery

Laser eye surgery can be the perfect treatment choice for astigmatism sufferers.

With Excimer laser correction, the oval shaped astigmatic cornea is made rounder by removing more tissue in one plane of the cornea than the other. And because laser eye surgery corrects nearsightedness and farsightedness as well as astigmatism all in one simple procedure, it’s the ideal solution for astigmatic patients.

NewVision Clinics offers the best surgery outcomes for astigmatism treatment

Astigmatism is commonly measured in several different ways by spectacle refraction, manual keratometry, topography and wavefront. These can all produce slightly different readings.

At NewVision Clinics we take all these multiple measurements into account when calculating the astigmatism treatment parameters for patients. Unlike many other laser eye surgery clinics, we not only treat the spectacle astigmatism but we also take into account the corneal astigmatism to produce exceptional visual outcomes. (For more on this see ASSORT).

Lasik Treatment

LASIK (Laser-Assisted-In-Situ-Keratomileusis) eye surgery is a safe and painless procedure.

Over 80% of patients having laser eye surgery will undergo this treatment, and over 35 million people have enjoyed its results worldwide. The result of our LASIK eye surgery Melbourne wide is simply fantastic.

PRK Treatment

Prior to the development of LASIK, Photorefractive Keratectomy or PRK Surgery was the first procedure. It has undergone many advances and innovations since its introduction more than 20 years ago.

Treatments

How do they compare?

The total time for each procedure is between 15-20 minutes for both eyes, although the laser treatment itself lasts only seconds. Long-term results are equally as good with either method although good quality vision is reached quicker with LASIK. For this reason LASIK surgery is the preferred choice for correcting vision for most patients.

LASIK Treatment PRK Treatment
Prior to the treatment, a hinged flap on the cornea is created either with a laser or a microkeratome. Prior to the treatment, the epithelial layer of the cornea is gently brushed away.
After treatment, the flap is replaced and the epithelium quickly repairs itself. After treatment, a ‘bandage’ contact lens is placed onto the eye. The epithelium grows back within days.
Healing is rapid. Healing takes longer to achieve.
Excellent vision is reached within a few hours and you can return to work the following day. Excellent vision is expected within a month although most patients can drive within 5 days and return to work in a week.
