1. Lasik is a two step vision correction treatment that’s been really effective in the treatment of nearsightedness, hyperopia and astigmatism.

The Benefits

  • The treatment of laser eye surgery is done with local anaesthesia (eye drops)
  • The primary endeavour, developing the flap, will require about thirty seconds for every eye, whilst the next period, reshaping the cornea, requires around 15 seconds
  • There isn’t soreness
  • Many have advanced eyesight, with no eyeglasses, about a couple of hours in the aftermath of surgery

The LASIK process

  • The corneal flap is made with the Intralase Laser
  • The flap is subsequently folded back so the excimer laser can easily reshape your cornea
  • The speed and accuracy using the Allegretto (excimer) Laser enables very small quantities of tissue (100 times leaner than the typical human hair) to be taken off, reshaping the cornea
  • The flap is then carefully repositioned exactly where it closes naturally with no stitches necessary
  • Your complete treatment is completed using anaesthetic eye drops and a mild oral sedative

2. The IntraLase Laser is the initial step in lasik eye surgery Sydney and is used to make a flap without using a blade

The advantages

  • A blade-free method of making the corneal flap that has replaced the microkeratome (a mechanical machine that utilises a metal blade)
  • Creation of the flap simply demands close to thirty seconds each single eye
  • Less risky, much more accurate while offering much better vision

3. Photorefractive Keratectomy (PRK) utilizes the excimer laser to correct the form of the cornea.PRK is a laser eye correction procedure of which will not entail making a corneal flap. Nonetheless, it will take longer for the eye to recoup and there is more uncomfortableness compared to with a LASIK process.

The drawback

  • A number of patients aren’t suited to LASIK and need a different treatment to repair their vision
  • A really narrow or wrongly shaped cornea often indicates patients are not fit for lasik eye surgery

The PRK Method

  • The surface cells of the cornea are taken away and the frontal surface of the cornea is reformed to alter the refractive fault.
  • The soft contact lens bandage is situated on the cornea to help the recovery process.
  • Regrowth of the corneal surface typically takes 3-4 days
  • Similar to LASIK the procedure is carried out working with anaesthetic eye drops and a mild oral sedative
