Laser Vision Correction
Laser Vision Correction, or Laser Eye Surgery as it sometimes is referred to, is the most commonly performed elective procedure in the world today. Laser vision correction refers to procedures that reshape the cornea with laser energy to correct nearsightedness, farsightedness, and astigmatism. These procedures can be customized to provide a unique treatment for each patient resulting in the best possible vision.
Laser Vision Clinic Central Coast is located within Central Coast Day Hospital at Erina and part of the Presmed Australia group of day hospitals. LVCCC is a state-of-the-art laser refractive facility. LVCCC is only an hours drive North of Sydney and post-operative follow up appointments can be arranged in Sydney. We provide the following kinds of highest quality bladeless laser vision correction procedures:
ReLEx® SMILE is the new laser technique for the gentle correction of vision defects. Unlike conventional LASIK, this procedure creates no flap and involves the use of only one laser (the femtosecond laser). Instead of vaporising corneal tissue to correct the underlying short-sightedness and astigmatism, ReLEx® SMILE removes a small piece of corneal tissue called a lenticule through a small keyhole incision of less than 4 mm.This opening is up to 80% smaller than those of the earlier LASIK treatment. No flap means a smaller risk of infections and quicker healing. And because no switch of equipment is needed during the treatment, the overall time of the treatment is also shorter.
LASIK is a safe, reliable and painless way to improve vision and reduce or eliminate the need to wear glasses or contact lenses. LASIK changes the way light is bent, or refracted, as it passes through the cornea so that it focuses properly on the retina and objects can be seen clearly.
CCDH’s LASIK surgery uses two computer-guided lasers instead of one as in previous generations of LASIK. The first ultrafast laser, a femtosecond laser creates a thin corneal flap of precise dimensions by sending microscopic laser pulses onto the cornea. This flap is then folded back to allow the second laser, an excimer laser, to correct your vision based on the exact specification bar measurement of your eyes. The flap is then gently replaced and aligned back to its original position, where it heals naturally without stitches. The entire procedure takes less than 15 minutes for both eyes. Patients experience a virtually painless procedure with potential for 6/6 or better vision and unparalleled safety. The problems experienced with use of the microkeratome to make a flap have been greatly reduced by this technology.
Conventional LASIK corrects your vision based on your prescription for contacts or glasses. Your level of vision correction is determined using the familiar “which is better, this or that?” vision test. This type of LASIK can correct the main types of refractive error: nearsightedness, farsightedness and astigmatism.
Wavefront-guided LASIK, sometimes called custom LASIK, creates a personalised map of existing higher order aberrations to correct refractive error and the more subtle vision problems. In some cases, existing higher order aberrations are severe enough to require this special treatment. Higher order aberrations may include subtle blurring, less clear visual contrast and even mild glare, halos or starbursts around lights at night
ASA (Advanced Surface Ablation) / PRK (Photorefractive Keratectomy)
ASA / PRK procedures are very effective for treating low to moderate amounts of short-sightedness and astigmatism. It is a straightforward and surgically less complicated procedure where the protective layer of the cornea is gently removed. The laser is then applied to reshape the corneal surface to the desired requirements. Following the cool laser treatment a contact lens is placed over the eye to protect it during the first few days of healing. Although the procedure is painless it is quite normal to feel some mild to moderate discomfort for one or two days following treatment. The effects of ASA / PRK are not instantaneous as there is an ongoing healing process with the cornea. Although the patient is able to see, vision will not immediately be clear and may take up to two weeks to recover. For this reason, it is recommended that two weeks be left between treatment of each eye.
