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 (farsightedness) 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.
