Laser surgery and refractive errors
Excimer laser is now safe and reliable alternative to the spectacle and contact lens correction of refractive errors of the eye. The essence of excimer laser surgery is a change of curvature of the cornea of the human eye by ablation of particular amount of tissue at a particular place on the front surface of cornea. In myopia the central cornea is flattened, aggravated in farsightedness and adjusted only in a particular axis in astigmatism cases. This is how correction of refractive error and change of dioptric power of the optical system of the whole eye (change of refraction) as a final result is achieved.
HOW DOES THE EYE WORK
In a healthy, perfectly focusing eye, light passes into the eye through the iris and pupil into a point of sharp focus that ideally should centre on your retina. Photoreceptors on the retina translate the light signal into electric impulses. The optic nerve sends messages to your brain, which translates the message into a picture – we understand this as ‘vision’. In other words the eye works in exactly the same way as a digital camera, but the picture is displayed on the camera’s screen.
What is a refractive error
The eye’s ability to refract or focus light sharply on the retina is based on two main anatomic features: the overall length of the eye and the curvature of the eye’s surface or cornea.
In most eyes, the correct balance of these two features does not exist. This is what we call a refractive error.
Myopia – shortsightedness – the image focuses in front of the retina
Hyperopia – long-sightedness the image focuses behind the retina
and with Astigmatism two focal points fall in two different positions on the retina
Myopia or shortsightedness (negative refractive error)
Myopia is a condition in which an image of a distant object becomes focused in front the retina, either because the eyeball axis is too long, or because the refractive power of the eye is too strong. This condition makes nearby object appear in focus and distant objects out of focus.
Excimer laser eye surgery is recommended for refractive errors in the range of - 0.5 – 12.0 D.
Hyperopia or longsightedness (positive (+) refractive error
Hyperopia is the refractive error in which an image of a distant object becomes focused behind the retina, either because the eyeball axis is too short, or because the refractive power of the eye is too weak. This condition makes close or distant objects appear out of focus.
Excimer laser eye surgery is recommended for refractive errors in the range of +1.0 to + 6.0 D.
Astigmatism (cylindrical refractive error)
Astigmatism is a condition in which an abnormal curvature of the cornea can cause two or more focal points to fall in different locations on the retina - making close or distant objects appear blurred or double. Unless the astigmatism is irregular, the range for the excimer laser eye surgery is not limited but most often +/- 7.0 Dcyl.

I had excimer laser surgery in 1998 and I must say that I have to date had no problem with the eyes and I'm happy. I want to thank, you helped me improve my quality of life.
Hudák Róbert
Hello Mr. Juhás, I would like to thank you once again for your work. I underwent operation (I had myopia -2.5 Diop .-) last year in October. I have no complications and in these days or weeks, I feel that it has really stabilized. I see exactly as I "wanted".
Tatiana Špačková, Trenčín
Hello Mr. Doctor. Firstly, I would like to thank you and say how grateful I am for the solution that you suggested to my friend and also regarding my eye laser operation. You're very nice person; really, I have never met with such helpfulness from the doctor. Best regards.
Jana Sivakova, Bratislava
Hello Doctor, in the first place I want to thank you for arranging of my stay and surgery. Accommodation was great and I think the operation was also successful. Thanks again.
Sincerely,
Mária Zelemova
Hello, I want to thank you for surgery that after 100 years I can see again and for that you have exceptionally agreed with special date and time of surgery. I am very grateful and as I did not manage to thank you personally, when it was over, let me do it at least via e-mail. Thank you very much for this "miracle".
Sincerely,
Maroš Kulhavy
I would like to thank Prof. Juhás and nurse Mrs Catherine and to all operational staff for repairing my eyes. Now I can devote to the dance and enjoy reactions of viewers without any problems. We have already started teaching Latin and salsa dances here in the UK. We already have first students and we hope it goes better and better. So I wish you all the best.
Sincerely, your patient

Mr Professor. First I want to thank you for a professional approach and surgery of my son. He had great vision problems since childhood, wore thick diopters and now need not to wear any glasses. Once again I thank you and your team, wish you good health and success in treating your patients.
Sincerely,
Andrea Labusová
Hello Doctor,
so now I can tell that I was so afraid of the operation over the weekend and I had no tearing of hair, no climbing on the wall as you told me . I was sleeping most of the time during the weekend, had no pain. I am grateful to finally see. I wanted to tell you personally but on Tuesday when I was at the first check I have not met you. Many thanks :-)) I hope you have a nice day :-))
Radovan Uhler
Thank Oftum and God for the opportunity to operate my eyes, I do not wear glasses already 7 months:) The first four days were a bit painful, but then no longer. I began to see properly after a month. Greetings to the doctor and nurse you are nice, professional and witty!
Jozef Durbak
You were fantastic. When I opened my eye next day, I thought that was a miracle. And it was. Thank you, thank you, thank you .......
Monika Urbánková
I underwent surgery on 9.12. and I'm very happy. I encourage all who think of surgery. My experience is excellent, no major pain after surgery and my vision was comparatively better immediately after surgery and now is excellent. I recommend.
Martin Dudik
My operation was on 30.10.2009, now it has been a year after, and as a sportsman, I am thrilled that I do not have to wear those glasses. The world is a little nicer.
Katarína Kramárová
Today it's exactly one year since I was operated in Oftum center in Bratislava and it is a wonderful feeling not to be constrained by glasses or lenses. This way I would like to thank the specialist staff who carries out their job fantastically.
Peter Švec
My surgery was 9/11/2008 and there is nothing better than being without glasses and have a good vision. I hereby wish to thank all the staff for performing good job. Thank you
