Laser Eye Correction Surgery

LASIK and transepithelial Photorefractive Keratectomy (transPRK) are the most common performed eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Dr Davey will decide which laser procedure is best suited and safest for your eyes for precise and best visual outcomes. Dr Davey uses the Schwind Amaris Laser which is a German engineered world leader in modern eye lasers.

When is laser eye correction surgery needed?

People with normal vision, their cornea bends or refracts light precisely onto the retina at the back of the eye. With people that are nearsighted (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, which results in blurred vision.

Glasses or contact lenses may correct the vision but reshaping the cornea will also provide the necessary refraction. There are several reasons why laser eye correction surgery may be needed, which includes under correction of the vision problem, overcorrection which may lead to straining the eye or eyes, problems experienced with the epithelial flap while it heals, or there is an infection.

There are many different causes of blurred vision. The common causes of vision problems include:

  • Refractive errors
  • Abrasions to the cornea
  • Trauma or injury to the eyes
  • Infectious retinitis
  • Age-related macular degeneration
  • Cataracts
  • Migraines

People with diabetes may also experience blurred vision when their high blood sugar levels fluctuate significantly.

What does surgery involve?

Dr Davey will first create a very thin, superficial flap in your cornea using a small surgical tool called a microkeratome or with the use of a femtosecond laser. Dr Davey will proceed by folding the hinged flap back to access the underlying cornea and then removes some corneal tissue with the use of an excimer laser. The excimer laser is used to reshape the cornea so that the light that enters the eye is more focused accurately on the retina for improved vision.

In the case where you are nearsighted, Dr Davey’s goal is to flatten the cornea, but if you are farsighted, a steeper cornea is desired. If you have an astigmatism vision, Dr Davey will use the excimer to smooth the irregular cornea into a more normal shape. The laser flap is laid back in place after the LASIK procedure, covering the area where the corneal tissue was removed. Lasik laser eye surgery requires topical anaesthetic drops and no bandages or stitches needed.

When should I see an ophthalmologist?

People that have a family history of eye disease, a history of eye injuries, diabetes or those
over the age of 65 should see their ophthalmologist regularly. In addition, the following
symptoms should be checked out by an eye specialist:

  • Changes in vision
  • Flashes of light
  • Floaters or specks in your vision
  • Lines that appear distorted
  • Darks spots in your vision
  • Decreased or blurry vision (even if temporary)
  • Double vision
  • Dry and itchy eyes

  • Eye pain
  • Eye or surroundings of the eye is red
  • Eye discharge or tearing
  • Bulging of one or both eyes
