Pre-operative assessment

This is where page introduction will go

The period before treatment is spent learning about what is going to happen. The first phase is to determine if you are have optical imperfections which can be dealt with successfully using excimer laser treatment.

It is essential that you discuss your needs and requirements and the likely outcome of your excimer laser treatment with Dr Delaney prior to surgery, in order that you have a realistic expectation of the likely outcome.

To assist you in this phase, we have a free initial assessment, carried out at Dr Delaney's Macquarie Street rooms - contact us should you wish to book a time.

Realistic Expectations

After thorough consideration of all the advantages and disadvantages of the treatment, a patient must make the decision to proceed with the excimer laser treatment, based on what they believe are realistic expectations of the outcomes of the treatment. If these expectations will not provide them with the vision they require then they should seriously question whether surgery is the best course for them to follow. What is a realistic expectation or requirement for one patient may be totally different for another. For example; a patient who does a lot of night driving for a living, will have different needs and requirements to a patient working at a computer screen or one working outdoors.

The criteria for excimer laser treatment

1. Stable refractive error
   No change in spectacle or contact lens prescription for the preceding one to two years.
   Myopia is not stable prior to age 18.
2. Freedom from certain eye disorders and medical problems.
   For example Herpes Simplex keratitis and rheumatoid arthritis.
3. Refractive error which falls within the treatment range of the laser.
4. You must not be pregnant

Dr Delaney then discuss the treatment with you, and as with all surgical procedures it will require your medical background, including age, general health, allergies and current medication.

Next, an instrument called a corneal topographer is used to measure many hundreds of points of the front surface of your eye and in doing so creates an accurate corneal map. Our automated equipment will test your vision, measure the shape of your eye, curve and thickness of the cornea, as well as your degree of myopia, hypermetropia and astigmatism. All this information is used by the computer controlled excimer laser at the time of surgery to provide a precise optical adjustment. This also allows Dr Delaney to assess the degree to which your eye needs correction and an accurate assessment of the degree of success that can be expected, including the selection of the appropriate technique.
