Types of Eye Surgeries for the New Vision

per 2 31 decIn Sydney, Expert Eye-Surgeons offer variety of eye-surgery procedures. The surgery procedures to correct different types of eye-problems and diseases are done by using laser based technique. The types of laser eye-surgery procedures are becoming very popular because of their great results and benefits. These procedures are called by different names such as Vision correction surgery, refractive laser surgery and laser eye surgery. Almost laser based eye surgery procedures work by reshaping the cornea which is a clear front part of the eye. It is done so that light traveling through it is properly focused onto the retina located in the back of the eye. Some surgeries also involve replacing the eye’s natural lens. Let’s discuss (in brief) different types of laser eye surgery procedures performed by eye-specialists in Sydney.

•    Laser in-situ keratomileusis is a procedure which is commonly known as (in short) LASIK. This is a procedure used to correct vision in people who are nearsighted, farsighted, and/or have astigmatism. It is performed to correct vision by reshaping underlying corneal tissue so that it can properly focus light into the eye and onto the retina.

•    Photorefractive keratectomy is a surgery procedure commonly known as PRK in short. In this is performed to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism. This procedure involves a process where eye surgeon uses a laser to reshape the cornea. This laser is used on the surface of the cornea.

•    LASEK is a short for laser epithelial keratomileusis. This procedure is a variant of PRK and is performed to treat nearsightedness, farsightedness, and astigmatism. In this surgery an epithelial flap is created and then epithelial cells are loosened using an alcohol solution. Then a laser is used to reshape the cornea and once the procedure is done the flap is replaced and secured with a soft contact lens while it heals.

•    RLE is short for refractive lens exchange. This procedure is also known as clear lens extraction. It is done to remove the natural lens of the eye and replace it with a silicone or plastic lens. This procedure is done to correct extreme farsightedness or nearsightedness. It involves making a small incision at the edge of the cornea and then natural lens of the eye and replaces it with a silicone or plastic lens.

PRK Treatment and Expert Eye-Surgeon in Sydney

PRK is a short form for Photorefractive Keratectomy. This treatment is type of refractive surgery which is performed to correct refractive-errors such as myopia (nearsightedness), hyperopia (farsightedness12) and astigmatism. This procedure is done by using laser technique. And all laser eye or vision correction surgeries work by reshaping the cornea which is a clear front part of the eye. Cornea is reshaped so that light traveling through it is properly focused onto the retina located in the back of the eye. However there are different surgical techniques to reshape cornea but in PRK treatment in Sydney, an eye surgeon uses a laser to reshape the cornea. This laser delivers a cool pulsing beam of ultraviolet light. This laser is used on the surface of the cornea unlike LASIK procedure. In LASIK, laser is used underneath the cornea. The procedure has advantages:

• There is less depth of laser treatment than LASIK procedure

• The procedure is suitable for patient with a thin cornea

• There is no risk of corneal flap complications

• This procedure has reduced risk of compromised corneal thickness

• This procedure is highly accurate in correcting many cases of nearsightedness

As everything has its own advantages and disadvantages, patients undergone the PRK treatment procedure may have mild discomfort, including minor eye irritation and watering, for one to three days following the procedure. And some patients may still require glasses after PRK. Typically, PRK patients experience sensitivity to light in the first 24 to 48 hours. And, within the first six months after surgery, other potential side effects may include loss of best vision with or without glasses and mild halos around images. Patients may need mild glare which can be permanent. This need depends on a patient’s pupil size in dim light. Finding highly expert eye-surgeon can eliminate the risks or complications. Eye-surgeons conduct consultation sessions, they do eye-tests and examinations and after evaluating complete medical history and current health-conditions and severity of refractive-error, they suggest the treatment procedure. It is very important to hire extremely knowledgeable and highly expert eye-surgeon in Sydney which is not a daunting task. Many sources are available to find the best eye-clinic in the locality or city and get the best eye-surgeon to handle the case and perform the surgery-treatment.

What You Need to Know about LASIK

perfect 29 decMany people around the world go for different types of vision correction treatments to regain their normal vision and get rid of the troublesome glasses or contact lenses once and forever. Out of all the available procedures for vision correction, the one that is the most popular is the laser eye correction treatment. Many clinics in cities such as Sydney and Adelaide are offering this treatment and helping thousands of people who are suffering from certain types of vision related problems such as long sightedness, short sightedness or astigmatism. And there are many reasons behind the ever growing popularity of this lased based treatment, including the fact that is very precise and effective.

LASIK is basically a combination of microsurgery and excimer laser procedure that has been developed specifically for the purpose of correcting a wide range of refractive problems related to vision. In most of the cases, patients are not required to wear contact lenses or glasses after the treatment as they are able to see clearly without using external vision aids. You might be a little surprised to know that exciemer laser was actually developed by a person of Indian origin in the USA. The person who discovered this laser was Rangaswamy Srinivasan. By working in tandem with eye specialists in the early 1980s, he was finally able to etch the cornea of the eye. And it was this experiment that actually led to the development of LASIK procedure.

LASIK surgery, as a treatment for vision related problems first came into being in the early 1990s. According to the latest figures, more than 25 million people around the world have undergone this surgery. As far as the market for refractive surgery is concerned, it exceeds more than $4 billion and is expected to grow at an exponential rate in the next few years. Refractive surgery includes all those laser based procedures which are performed to treatment certain vision related problems such as myopia, hypermetropia, astigmatism and prebyopia.

Among the most popular refractive errors procedures, the ones that top the list are LASIK and LASEK. There is one big difference between the two procedures. In LASIK, the main focus is on the stroma corneal tissue which is thinned out using advanced lasers. LASEK, on the other hand, concentrates mainly on the epithelial tissue which is made smaller with the help of advanced lasers. Both these procedures do not take more than 20 minutes for both eyes. There are best clinics available in Sydney for Laser Eye Surgery.

Monovision Treatment in Sydney

A procedure in which one eye is used for distance vision and the other eye for near vision is known as Monovision. Actually this procedure is beneficial in a way where treatment adjusts each eye to a specific purpose (aexpert-tools_face-brush_model-shot_143308s mentioned in first line of the blog) and the human-brain soon adjusts to the vision asymmetry and converts it to perfect vision! This is the reason why most people (belong to age group of 40 and above) choose monovision treatment. The treatment is performed by use of laser technique. Laser based treatments have become popular due to higher success rate and great results.

The Monovision procedure uses laser correction technology. In this procedure, laser is used to correct presbyopia which is the age-related condition that generally requires patients to wear bifocal glasses. Actually, what happens is this method works because human brain learns to adapt to which eye sees at which distance. And because this type of laser surgery is a permanent solution, people prefer to go under this procedure. People belong to age group of 40 and above are common candidates for this procedure. Those are above 40 years and are nearsighted can undergo LASIK for its treatment. People who have developed presbyopia can be benefited from monovision as well. LASIK treatment for Monovision in Sydney is a refractive surgery technique. It involves use of the excimer laser (a laser-device) to remodel the curve of the cornea. It is used to surgically correct myopia, farsightedness, astigmatism and presbyopia in a rapid and safe manner.

Expert eye-surgeons perform the types of surgery methods for presbyopic patients. A range of treatments is available for patients. Experts or Consultants discuss each and every important detail and all the options available with patients before they perform any treatment. People can gather important information related to monovision treatments, benefits, about the procedure, side effects and precautions etc on internet. They can use this source to find out the available experts and eye-doctors and surgeons offering variety of treatments and procedures. They can find out the eye-clinic center in their locality or area, or city. In Sydney, expert-doctor informs and educates patient about the surgery or procedure but if you have any query or confusion without hesitation ask your doctor. Your medical history and current health conditions will be evaluated before you under go any such laser eye-surgery procedure.

Laser Treatment To Correct Myopia

Myopia is a type of refractive error. It is also known as Short-Sightedness. It can be treated with imagesdifferent medical-treatments and procedures. One of the most effective and efficient treatments is based on Laser Technique. This type of refractive error can be treated by laser treatment. Again, there are types of laser treatments available (and done for different eye-problems). All laser myopia treatments in Sydney for eye-problems are performed and problem is corrected by reshaping cornea. Let’s understand what laser eye-surgery procedure involves. The first step in procedure is to lift back a thin layer of the cornea. And then, ultraviolet light and high energy pulses from the excimer laser reshape the internal cornea. For information, treating high levels of near-sightedness, astigmatism and moderated amounts of far-sightedness is also possible. How? It is possible simply by adjusting the laser. It is completely an expert’s or eye-surgeon’s job. Well, coming back to the procedure, the next step after the tissue has been reshaped is replacing the flap in its original position. Then it is left to heal naturally. Healing process is fast. The advantageous things are:

• Number one: It corrects vision problems

• Number two: It helps patient having clear vision without using eye-glasses or contact lenses (in most cases). It actually can eliminate the need to wearing eye-glasses or contact lenses

• Number three: It does not require any surgical equipments

• Number four: It is not associated with any bandages. No stitches are required

• Number five: A minimal of discomfort a patient may feel which can be eliminated using eye-numb-drops. It does not pain

• Number six: The laser eye surgery procedure is fast, rapid, safe and gives great results

The laser technology has marked highest success rate. The procedure is worth going under because it gives great results by correcting different types of eye-problems and refractive-errors. In Sydney, there are many eye-care-clinics and centers where expert eye-surgeons are offering variety of services including regular eye-examination or eye-check-up, different types of surgeries and procedures and all necessary medical assistance. People can gather information using internet. There are web-portals to get detailed information to contact experts or staff members, get appointment and consult problems with experts to get the proper treatment.

Cataract Surgery and Misconceptions

When one discusses about cataract, a lot of people find themselves short of clarity as there exist quite a few misconceptions as well as those old wives’ tales. There is no dearth of myths about this vision related complication with the top ones being that cataract grows on top of eyes and that it gets ripened up if not taken care of in time. In order to save you from such pieces of misinformation that are abound in the market these days, here is a short list of some common myths and facts related to cataract and cataract surgery that you must be aware of at all cost.

imagesMyth 1: Cataract tends to grow on top of human’s eyes

Fact: This can easily be touted as the most common and the biggest myth of all related to cataract. But as mentioned earlier, this is nothing but a huge misconception among people across the globe. Cataracts are basically a clouding of the eye’s lens. And as you must know, lens is located within the eye. So it is just not possible for cataract to grow or develop on top of one’s eyes. The eye lens is actually constituted of water and protein fibers. These are arranged in such a manner that they allow the passage of light through them pretty easily. However, with age these protein fibers get clumped together around in small portions. When this clumping gets big enough, it takes the form of a disease which we refer it to as cataract.

Myth 2: Cataract can easily be removed with the help of laser surgery

Fact: This is again one of the biggest myths surrounding cataract surgery in Sydney. What you ought to know is the fact that cataract just cannot be ‘removed’ with the help of even the most advanced forms of lasers available these days. This is because the so called clumping of protein takes places inside the lens, and not over it. So, it is practically not possible to remove the cataract. The advanced laser eye surgery done these days to treat cataract involves breaking up of the natural lens. This lens is then replaced by an instrument used in laser surgery called phaco probe. Once the natural lens is removed, it is then easily replaced with an highly advanced artificial lens within the eye where the natural lens was located. So this is how the actual procedure takes place.

Laser Surgery for Eye-Refractive-Errors

Laser Surgery for eye has become very purposeful for people suffering from different types of eye-problems, refractive-errors or eye-diseases. The most common form of laser eye surgery is Laser-assisted in Situ Keratomileusis. Generally it is known as LASIK, in short term. This laser treatment is performed on patients suffering from myopia (also known as nearsightedness), hyperopia (also known as farsightedness) and astigmatism. Different types of refractive surgery are performed by expert eye-doctor or eye-surgeons. Most of the laser treatments for eye work by reshaping the cornea. IN LASIK procedure, cornea is reshaped to enable light entering the eye to be properly focused onto the retina for clearer vision. Typically, the procedure is not associated with any pains. It is pain-free, in most cases. And it is so quick and fast that it can be completed within 15 minutes for both eyes. Till now, laser eye surgery procedures have marked great success in order to achieve effective results as it helps in improving vision or refractive error so that patient(s) can have correct vision. More importantly it helps in eliminating need to wearing eye-glasses or contact lenses. Depending on expert’s evaluation and patient’s refractive-error (if patient is not a good LASIK candidate) then number of other vision correction surgeries is available too.  For example: custom wavefront LASIK, Epi-LASIK, IntraLase “Bladeless” LASIK and LASEK. Other surgeries are PresbyLASIK and PRK. The procedure of laser surgery for eye involves following process:

Eye-surgeon uses a mechanical surgical tool to create a thin and circular ‘flap’ in the cornea. Then the hinged flap is folded back to access the underlying cornea. The underlying cornea is called thestroma. Some corneal tissue using an excimer laser is removed. This excimer is a highly specialized laser that uses a cool ultraviolet light beam to remove microscopic amounts of tissue from the cornea to reshape it. This is done so that it more accurately focuses light on the retina for improved vision. Once the laser reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed. And cornea is allowed to heal naturally. This process may require topical anesthetic drops to numb eyes and to eliminate the discomfort. This process is not associated with any bandages or stitches.
