How the eye works like a camera – and why laser eye surgery is the answer when it fails.

02 Dec 2014




We don’t often sit back and marvel to ourselves at just what an incredible organ the eye is. But if we consider just for a moment about how complex this vital little organ is in terms of how it actually operates, we should really be in awe at its sheer capabilities. It is essentially a camera which is given to us at birth, and an essential and indispensible tool which is completely invaluable to us right the way through our lives. Driving a car, playing sport, shopping for goods, interacting with people, enjoying holidays, cooking for the family....the list of daily pleasures (and let’s be honest, even the simple things that we take for granted), which are enhanced just by virtue of full and clear vision, as granted by our eyes, is almost endless.

Comparing the human eye and the man made camera.

When we compare the human eye to the man made camera, it sometimes seems like an almost too obvious comparison to make but the simple truth is that the camera and the eye operate in an almost identical manner. Both have a powerful lens function, whose purpose it is to control natural light in order to bring an object into focus. Similarly, both have an identical pupil function – in a camera this is the aperture, that small hole through which light passes, whereas in the eye this exact equivalent is known as the pupil. Both the eye and the camera also have a protective covering, designed to protect the lens – this is the cornea in the case of the eye and the lens cover where the camera is concerned. And finally, there is the all important imaging unit which is what converts information into picture form. In the case of the eye this is the retina, in the camera it is be the memory card or similar.
Because of the many similarities then between the eye and the camera, just as a camera may at some point breakdown and need repairing, the eye too will generally suffer from some vision problem or other, at some point in its life cycle. Thankfully though, just as a camera can for the most part be repaired back into perfect working order, so too can the eye!


Free initial consultation to determine suitability for laser surgery

Most eye complaints and vision related problems are very common and are therefore easily and readily treatable through laser eye surgery. So, if you have any vision concerns, do not for second think that this is something unusual because the opposite is actually the case. And to help you put your mind at ease, Optilase offers a free initial consultation with one of our laser Optometrists, who will conduct a thorough eye examination (to see what the problem is exactly) and determine whether you are a suitable candidate for laser eye surgery.

What eye conditions are treatable?

Myopia, or near sightedness as we more commonly refer to it, is one very common condition which affects very many people. The problem is caused by a refractive error (the eye does not bend light properly), which causes difficulty focusing on objects in the distance. The good news is that this condition is very successfully treated through laser eye surgery.
Hyperopia, or long-sightedness, is another very common condition affecting a high percentage of people, and this too is caused by a refractive error....but in this case, it is up close objects as opposed to those in the distance, that are blurred and out of focus. Again, this condition is quickly, easily and painlessly treated here at Optilase....just 10 minutes and you’re vision is perfect again!
Astigmatism, again caused by a refractive error, is another very common condition which can once again be corrected by us here at Optilase through laser eye surgery.
Whatever your vision complaint may be, just think of the camera analogy! Cameras will, from time to time, break down simply because there are so many complicated parts working in unison in order to provide the perfect picture. Essentially, wherever there are moving parts, whether it involves a man-made machine or a part of the human body, there will always be small issues which need fixing and correcting. The eye is really no different – and just as a camera can generally be very easily fixed nowadays, the same is true of the eye, thanks to the huge advancements in laser eye surgery!

So happy with my results! There was a very quick turnaround between my consultation and the surgery and they were so flexible with appointment times. There is a lot of waiting around on the day of surgery but once started it’s a very quick process! Would highly recommend to anyone considering!

Very happy so far, was a thoroughly professional experience from the consultation to the surgery to post op checks. Was slightly delayed on day of surgery but all worth it in the end. Would definitely recommend to anyone choosing to go down the laser eye surgery route.

I had laser eye surgery one week ago. It was by far the best decision I’ve ever made. I was extremely nervous about getting the procedure done, so I did get a second opinion on it. The service optilase offers was by far superior than anything else offered by other places. They were always happy to answer questions, and even got my optometrist, Michaela, to call me back to answer questions I had. On the day of surgery, I was in and out within an hour - super quick and efficient. The surgeon was very reassuring as were the whole team. By that evening there was a noticeable improvement in my vision, and by the next morning I had better than 20/20 vision. The precision of my vision now is indescribable: everything is so much clearer and life is just better! By far the best decision I’ve ever made. Thank you Michaela & Team Optilase for all of your help. I would highly recommend to anyone.

The staff were so friendly and helpful and made the whole process very easy. I got emails and phonecalls with all the information I needed and more from when I booked my first consultation until after the surgery. I had LASIK, which was quick and comfortable. My surgeon was kind and thorough and he took the time to chat before and after the procedure. It was all just generally easier and more pleasant than I expected and I’m so glad to have had LASIK here

Best decision I’ve ever made! The clinic in Ely place was incredible- from start to finish you are so well looked after and all the staff are so incredibly nice! Anyone wondering whether they should do it , go for it!! I can’t believe I waited so long!!

The support from the stuff is incredible. They are always willing to help and answer any questions you may have, both pre and post procedure. I had the PRK procedure and although I am only just at the 2 week mark I can say that my recovery will take longer than I expected so that was slightly disappointing. Though I am aware recovery times differ, I was surprised because I was consistently told 2 weeks recovery time.

Had a brilliant experience at Optilase, 2 weeks from my consultation I was in to get my LASIK surgery after being told I was not eligible in other clinics. The staff were so friendly and reassuring I really felt in safe hands.
