I happen to be a qualified Optician, and managed a laser clinic for a few years quite a few years ago.
I have the following advice:
1. DO NOT go on budget
2. DO NOT be done on a brand new machine
3. DO NOT believe the hype about how many procedures a company has done world wide
What is important is this:
The ammoutnt of experience has the particular (usually locum) doctor had, with the particular laser / equipement in that particular clinic.
Brand new lasers or brand new technology need to prove themselves a bit to a doctor and settle down in terms of thier performance and output. Statistically, you have a higher chance of regression when all the variables are new
COMPANIES like boots, optical express etc.. know nothing about laser surgery themselves - they are merley providing the space and framework to make it happen - they use specialist ophthalmologists - who are paid grandly for thier individual skills, and provide the equipement for them
What is important is
1. the advice they give you before - make sure you are seeing the doctor, not an optical assistant who had hald a days training
2. the experience of the specific Doctor
3. the immediate backup and aftercare (for a week or so) - are they available, when, how long - and willthe DR be availablefor you
4. the inclusion of long term after consultations
If this feels like a finacial procedure - you are in the wrong place. If it feels like a medical procedure - then you can feel more comfortable with your choice about where you went
I would be extreemly wary about paying bargain basement prices for this, or getting the procedure done in a rush (the very best doctors make you wait)
