Laser Eye Surgery for Astigmatism - 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. NewVision Clinics has a number of options when it comes to laser eye surgery for astigmatism.
Astigmatism
What is Astigmatism?
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 for Astigmatism
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 short-sightedness and long-sightedness as well as astigmatism all in one simple procedure, it’s the ideal solution for astigmatic patients.
NewVision Clinics Offers the Best Outcomes for Laser Eye Surgery for Astigmatism
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.

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.
SILK Treatment
SILK™ (Smooth Incision Lenticular Keratomileusis) is a technologically advanced, keyhole laser vision correction procedure that may allow people to see the world free from glasses or contact lenses. With the SILK™ procedure most patients experience outstanding vision from day one with fast visual recovery – but results can vary from patient to patient.
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.
| PRK | LASIK | SILK |
|---|---|---|
| Prior to the laser treatment, the epithelial layer of the cornea is gently brushed away. | Prior to the laser treatment, a hinged flap is created on the cornea either with laser or a microkeratome. | Laser is used to create a lenticule within the cornea through a key-hole incision. |
| After the laser treatment, a bandage contact lens is placed onto the eye, while the epithelium grows back within a few days. | After the laser treatment, the flap is replaced, and the epithelium quickly repairs itself. | After the laser treatment, the lenticule is removed via the small key-hole incision to reshape the cornea. |
| Healing takes longer to achieve, compared to LASIK and SILK. | Healing is rapid, compared to PRK and SILK. | Healing is faster, compared to PRK. |
| Excellent vision is expected within a month although most patients can drive and return to work in a week. | Excellent vision is reached within a day, and most patients can return to work the following day. | Excellent vision is achieved within a week, and most patients can drive and return to work in less than a week. |
