Frequently Asked Questions
Wavefront Treatment & IRIS Recovery Questions
Q. How many measurements does the Wavefront take?
A. Our Wavefront measures 80,000 to 100,000 points of the eye. Please see this website: www.ophthalmic-devices.com/schwind , the part for your attention is the Schwind Corneal Wavefront Analyser. With our Schwind laser we also have active 6D video tracking of the eye, most places offer 3D. More information can be found here.
Q. I am retinitis pigmentosa(rp) patient. As I know this is a cornea disease. Is Wavefront helpful for rp?
A. Wavefront can only be applied in conjunction with standard laser eye surgery. It is therefore not a separate procedure altogether. I am sorry but it is not helpful for Retinitis Pigmentosa.
Q. What is the difference between Intralase Lasik and Wavefront Lasik? I cannot see a price guide for Intralase Lasik.
A. We only offer Intralase LASIK or Intralase LASIK Wavefront. LASIK involves creating a flap on the surface of the cornea which is gently lifted and the underlying tissue treated with the laser. This procedure is relatively popular as the recovery time is very quick (around 24 hours) with very little if any discomfort experienced during the first few hours. The Intralase is the femtosecond laser platform we use to create this flap hence Intralase LASIK, all laser LASIK. Wavefront is an addition to the surgery and is a mapping system. Using thousands of beams of light we are able to accurately map the surface of the cornea to determine if there are any imperfections or undulations across the treatment area. Using this system within the Intralase LASIK we can tailor the treatment to match your eyes unique shape and surgery specification.
Q. Is the Wavefront treatment performed at Optimax Customised Wavefront or Wavefront Guided? And is it the same Wavefront treatment that other laser eye surgeries use?
A. Optimax uses an advanced Wavefront diagnostic machine. The Wavefront is customised to the individual patient.
Q. Do you use 3rd Generation Wavefront technology or 2nd Gen?
A. Each company uses their own brand and manufacturer of laser and each manufacturer will have their own 'Generation' of technology. This reflects the upgrade in their technology for their particular Wavefront system. In comparison each company's level of technology is very similar and offers similar results. Technology should not be the only basis of your decision as this only has a slight bearing on the results that can be achieved. It is really all about the skill and technique of the surgeon who is performing the surgery. All of our surgeons are fully qualified ophthalmic surgeons and we can supply with you with their information, in terms of results, etc. to help you make your decision.
Q. What is Wavefront treatment and how much is it?
A. Wavefront is a type of treatment tailored to the individual optics of your eye. Standard treatment (without Wavefront) gives very high quality results for many patients, however people's eyes are not always 'standard'. Patients with large pupils who were previously unsuitable for Laser treatment due to poor night-time vision can no be successfully treated using this procedure. Wavefront could give you better vision than your glasses or contact lenses. The surface of the cornea is measured to detect imperfections to enable precise treatment on each section of the cornea. This means that your eye receives optimum treatment tailored to its individual shape. Wavefront especially benefits those, as mentioned above, with high prescriptions, large pupils and poor night-time vision. Night-time complications are reduced by improving contrast sensitivity of vision in low lighting. Optimax uses the most advanced Wavefront diagnostic machine available in the market place. The Nidek OPD (optical path difference) device measures the progress of 8,000 waves of light as they pass through the eye. These data points are used to program the laser to correct the corneal surface.
Q. My night vision is poor and when driving can be a bit scary - is there anything I can do to improve this?
A. We offer Wavefront which is an addition to the Laser treatment. The prescription of the surface of the cornea is measured detecting imperfections allows us to determine the correct treatment for every part of the cornea. This means that you receive the optimum treatment tailored to the individual shape of the eye. Wavefront enhances the procedure by improving treatment for those with poor night time vision or large pupils. This results in increased contrast sensitivity in low lighting and reduced night-time vision complication.
Q. About 30 years ago I had radial keratotomy on both eyes to correct my short sightedness (the Russian razor blade technique). One eye was successful but the other was not as the lens did not heal to form a true spherical segment. I manage quite well with reading glasses but it would be better if I could get the distorted lens corrected for distance. Can you take off the lumps and bumps as required to produce a spherical lens?
A. You should be able to have laser surgery to correct the distance vision and you should be fine to have Wavefront to remove those horrid lumps/bumps. However we would not be able to offer you any correction due to our policy of not treating someone who has been elsewhere. So keep trying other companies and you will find a company that can do the correction for you.
Q. I'm looking into having laser eye surgery but have heard rumours that your night vision isn't very good afterwards, is this correct? Also how long is the healing process and is it painful?
A. We at Optimax offer Wavefront Treatment which enhances an already effective procedure in the Lasik or Epi-Lasek. This treatment is very affective for those with large pupils whom experience glare/halos at night. By having Wavefront with the Laser Treatment the risk of night-time glare will be greatly reduced. The healing process for Laser treatment depends on which type of treatment you have, Lasik with Wavefront has a 1-2 day/s recovery and is pain-free, Epi-Lasek with Wavefront can take up to 1 week and there can be mild to severe discomfort for the first 2-3 days.
Q. I had laser treatment 4 years ago, my night vision is still very poor and I find it very dangerous to drive at night. Can this be rectified with further surgery?
A. Yes you maybe able to get the Wavefront treatment but you need to come in for a consultation first, please call customer service on 0800 093 1110.
Q. You said Wavefront is a customised treatment profile which matches the bumps etc. on the eyes' surface. What exactly are these bumps?
A. By bumps I mean natural undulations and imperfections on the surface from perfectly round. Most people don't have any bumps of importance and their vision is perfect with glasses. But if they do exist we can remove them and improve your vision over that which glasses can achieve.
Q. Do you do iris recognition?
A. Yes, All our lasers are equipped with very fast eye trackers (200Hz) which lock onto the pattern of the iris during treatment. This ensures that the treatment is accurately positioned on your eye and if you move your eye during surgery the laser follows it.
