Laser Eye Surgery Perth
TYPES OF LASER EYE PROCEDURES
As one of the five senses, the human eye has become integral to everyday living and functioning, helping people to interact and engage with their environment. When issues arise, this can limit sensations and restrict your daily abilities. Thankfully, modern medicine advances have allowed us to offer an even better solution to glasses and contact lenses – laser eye surgery.
Laser eye surgery, also known as refractive or vision correction surgery, is a surgical procedure undertaken by those seeking to correct or improve their eyesight and finally dispose of their glasses or lenses. There are a number of different laser eye treatment options available at WA Laser Eye Centre, suitable for those who may be short-sighted, long-sighted or have age-related eyesight issues. Using the most advanced technology available in today’s market, our leading surgeon Dr Robert Paul will help you understand your vision treatment options and assist you with finding the most suitable laser solution.
After your free consultation with our centre, you will be informed as to which type of refractive surgery we believe will greatly benefit your lifestyle and improve your eyesight. If you have concerns about wearing glasses, or are suffering from eyesight related issues, please do not hesitate to contact us today.
LASIK Eye Surgery
Laser Insitu Keratomileusis, also known as LASIK, is the most common form of refractive surgery performed to correct refractive eye errors as it not only has a short recovery period, but it has also been shown to be effective for those with myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism (blurry vision due to unfocussed light on the retina). Other advantages of undergoing LASIK surgery include no scarring, rapid visual recovery, little discomfort and the ability to perform surgery on both eyes at the same time.
LASIK is a two-step procedure. Firstly, a specialised laser called a Femtosecond laser is used to create a corneal flap which is gently folded back. Next, a second laser called an Excimer laser is applied smoothly, reshaping the cornea and correcting the refractive error. Once this is completed, the flap is replaced to cover the newly reshaped corneal tissue and the healing process begins. The eye heals rapidly and the flap becomes adhered within a few minutes assisting with the healing process. To learn more about this procedure, please click here.
PTK Eye Surgery
Photo-Therapeutic Keratectomy is a type of laser surgery performed specifically to treat cornea injury or disease issues such as scars on the cornea or other types of corneal surface disease. Unlike LASIK, this type of surgery is used when more traditional methods have failed and it does not include laser vision correction. Instead, PTK might be undertaken if the patient has Recurrent Erosion Syndrome (RES). Our Perth laser vision centre can answer any questions you may have regarding this specific treatment option.
Corneal Ring Segments
Intrastromal corneal ring segments (ICR) are clear, micro-thin prescription inserts made of biocompatible plastic. A laser is used to first create a channel before placing the rings between the layers of corneal tissue, causing the central cornea to flatten, correcting mild near-sightedness and astigmatism. Kerarings are used for patients with Keratoconus, an eye disease that causes a thinning and bulging of the cornea. One of the main advantages of corneal ring segments is the fact that they are minimally invasive and very effective. For more information about this laser eye surgery, please contact us today.
PRK stands for Photorefractive Keratectomy, a procedure which involves first manually removing the surface layer of cells on the cornea called the epithelium before the Excimer laser is applied to correct the refractive error. A contact lens is placed over the eye for protection and to assist with the healing process. Patients undergoing PRK can expect to notice an improvement in their vision once the surface epithelium has healed – usually within 48-72 hours, with continued improvement over several weeks.
Other terms are often used to describe modifications to the PRK procedure. Modern treatment technologies have rendered most of these techniques outdated, however PRK continues to be an effective treatment option for some individuals who are not suited to LASIK. Some alternative terms for PRK include:
Laser Assisted Epithelial Keratomileusis is very similar to PRK, however, after the Excimer laser is applied the surface layer of cells are replaced over the cornea and a contact lens is applied to assist with the healing process. Healing times are also similar to PRK.
This procedure is similar to LASEK, however the main difference is the way the flaps are produced. With epiLASIK, the surface layer of cells are removed using a blade. This type of treatment is certainly not for everyone. If this is suggested as a solution for you, please do not hesitate to ask why. Often, epiLASIK is more suitable for those with thin corneas or insufficient tissue for a LASIK flap.
TEMLA, also known as Trans-Epithelial Minimal Laser Ablation, is a type of laser surgery which involves no blades. First, The Excimer laser is applied to remove the surface layer before the laser reaches the permanent layer of the cornea (the stroma). Although associated risks are very low, visual results can be more variable due to the variation in epithelial thickness.
Advanced Surface Laser Ablation is another term for standard PRK.
