 Wavefront Guided treatment
What is it for?
Trying to improve on the optical imperfections of your eye beyond that which glasses alone can correct.
Wavefront Guided treatments usually result in better outcomes. However, it is worth noting that this is still an evolving field – in fact, some Wavefront Guided treatments actually work less well than
the standard treatments on the same laser. Asking your surgeon to provide data on
the relative benefit of Wavefront Guided treatment is recommended, as some clinics will charge extra for this.
What actually happens?
The measurement obtained from Wavefront Aberrometry (see above) is combined with the prescription in your glasses, using software that delivers a customised shape change to the cornea.
How does it feel?
You feel nothing.
How does it benefit you?
A small percentage of patients may benefit from a wavefront-guided treatment. In general, most patients would benefit more from a wavefront optimised or customised tissue removal ablation profile (the shape of tissue removed by the laser).
Customised Wavefront Optimised treatment
What is it for?
Tailoring the treatment to your eyes, accounting for more than just the prescription in your glasses. Customised Wavefront Optimised treatment planning software enables the highest level of customisation for each individual eye, based on night vision simulations, contrast sensitivity and other corneal and ocular parameters.
What actually happens?
Customised Wavefront Optimised treatment software goes beyond ‘generic’ Wavefront Guided treatments (see
above). In simple terms this is like the difference between a standard ‘off the
peg’ suit that you would find on the High Street and a bespoke suit that has been custom-tailored. Using specialised bespoke software, your surgeon can change the parameters of your treatment based on the Wavefront measurement to create an even better result than that obtained by simple Wavefront Guided treatment.
