Laser eye surgery is used to reshape the cornea, the eye’s outermost lens, which is responsible for bending and focusing light within the eye to help create the images we see.

The procedure uses a strong beam of light to correct the cornea’s focusing power.

Laser eye surgery has been used since the 1990’s and is well-recognised for its ability to decrease or completely eliminate the need for glasses or contact lenses.

Recent technological advances with laser eye surgery have enabled the laser to now reshape the cornea without disturbing the eye’s surface.

There are three types of laser eye surgery performed at KindSIGHT, being PRK (photorefractive keratectomy), LASIK (laser assisted in situ keratomileusis) and SMILE (small incision lenticule extraction).

PRK (Photorefractive Keratectomy)

PRK (Photorefractive Keratectomy) is a type of laser eye surgery used for mild to moderate vision correction. It is one of the original laser eye surgeries offered for vision correction. It is also often referred to as ASLA (Advanced Surface Laser Ablation) or Advanced PRK.

The procedure involves gently removing part of the surface layer of the eye. The laser is then applied directly to the cornea for reshaping.

The PRK laser is a ‘cool’ excimer laser that doesn’t burn or damage surrounding tissue.

The PRK Eye Surgery Procedure

  • The eye is first numbed with anaesthetic eye drops
  • An alcohol solution or specialised brush is then used to remove the outer layer of cells before tailored computer-controlled laser pulses reshape the cornea.
  • A clear contact lens is then placed over the eye for four to five days to enable the surface layer of cells to heal.

  • The PRK procedure usually takes around 15 minutes and both eyes can be treated at the same time.

While recovery from PRK is slower than with other laser eye surgery procedures, vision will gradually improve over a few weeks.

LASIK (Laser Assisted in Situ Keratomileusis)

LASIK (Laser Assisted in Situ Keratomileusis) is the most common type of laser eye surgery performed today.

LASIK involves the use of two lasers, the first to create a small flap in the cornea and the second to reshape the cornea.

LASIK’s advanced eye-tracking technology is based on that used at NASA and enables surgeons to accurately track the eye during surgery at several hundred times per second.

The first LASIK laser is an ultra-short pulse, or femtosecond laser that creates a very fine, uniform flap. The second LASIK laser is a ‘cool’ excimer laser that ablates the unwanted areas. Neither burn nor damage the surrounding tissue.

The LASIK Eye Surgery Procedure

  • The eye is first numbed with anaesthetic eye drops
  • A flap is created by the first laser which is then lifted and pulled back to allow the surgeon to place tailored, computer-controlled laser pulses directly onto the cornea.

  • After reshaping, the flap is folded back into place over the cornea where it re-attaches almost immediately and heals on its own within days.

  • The LASIK procedure usually takes five minutes and both eyes can be treated at the same time

Final vision correction with LASIK is usually achieved immediately, however, on rare occasions it may take a few weeks for the eyes to stabilise.

Worldwide, cataract surgery is the most frequently performed surgical procedure. In Australia, more than 200,000 cataract procedures are performed every year.

Cataracts can be removed at any stage and you do not have to wait for them to ‘ripen’ before having surgery. Because cataracts will continue to progress over your lifetime, if not treated they will eventually cause blindness.

No matter how mature your cataracts are, it is always ‘possible’ to remove them.

The decision to proceed with cataract surgery ultimately comes down to whether you perceive that the benefit of having the operation outweighs the small risk associated with treatment. The eye surgeons at KindSIGHT are only too happy to discuss this in detail with you.

The timing of surgery is different for everyone.

Making the decision to have your cataracts removed usually depends on the following:

  • The degree your sight is affected
  • Your most common daily activities or vision requirements
  • If you only have sight in one eye
  • If you have any other eye disease

SMILE (Small Incision Lenticule Extraction)

SMILE (small incision lenticule extraction) is the latest advance in laser eye surgery, taking laser eye surgery to a whole new level.

It is minimally invasive with one laser used to cut a precise disc of tissue which is removed through a tiny laser incision.

SMILE is a minimally invasive, single-step process, with one laser used to cut a precise disc of corneal tissue which is subsequently removed through a tiny laser incision.

The entire SMILE procedure is performed within the cornea without having to cut the eye’s surface in order to achieve reshaping.

The SMILE laser is a femtosecond, or ultra-short pulse laser that doesn’t burn or damage surrounding tissue.

The SMILE Eye Surgery Procedure

  • The eye is first numbed with anaesthetic eye drops
  • The laser is then used to shape the disc, known as a lenticule.
  • The same laser is then used to make an incision of less than 4mm to remove the lenticule.

  • The SMILE procedure usually takes around 30 seconds and the incision heals on its own within days. Both eyes can be treated with SMILE at the same time.

Final vision correction with SMILE is achieved immediately and there is a very fast recovery with limited down time following the procedure.
