What Is ReLEx SMILE Laser Eye Surgery?

ReLEx SMILE (small incision lenticule extraction) is a keyhole procedure which eliminates the need for a corneal flap (as in standard LASIK Laser Eye Surgery). It also eliminates the prolonged healing time associated LASEK / PRK.

This minimally-invasive procedure provides more accurate and safer laser eye treatments and allows us to treat higher prescriptions and those with dry eyes.

ReLEx SMILE can be performed in considerably less time than standard LASIK Laser Eye Surgery, and can significantly reduce post-operative discomfort & dry eye (in some cases eliminating them completely).

ReLEx SMILE is most often suitable for patients who are short-sighted – particularly those who are contact lens intolerant or have thin corneas and who may have been found unsuitable for standard Laser Eye Surgery.

London Vision Clinic was the first UK Laser Eye Surgery clinic to offer ReLEx SMILE. Professor Dan Reinstein explains why this is such an important development:

“Laser Eye Surgery is already an extremely safe and very effective surgical procedure. With over 20 million treatments carried out to date, it is also the most popular elective procedure in the world. ReLEx SMILE represents the next-generation in vision correction treatments”

Why choose ReLEx SMILE:

  • Minimally-invasive “keyhole” approach
  • Knowledge Dispels Fear

      Can people with psoriatic arthritis undergo this procedure?

      • Bethany Kingsley 22/08/2016 at 07:55

        Hi Krish,

        Thank you for your questions. Patients with Psoriatic Arthritis can potentially be suitable. It is on a case by case basis, and we would most likely need you to have a consultation with an inflammatory specialist to work in conjunction with your laser eye surgeon. Please call the clinic on 0207 224 1005 or email info@londonvisionclinic.com if you have any further questions.

      I am a -10 shortsighted 70yr old and have recrntly had an operation to correct a lazy left eye through a new procedure requiring a cut in the vitreous humor to adjust the muscles. However, I cannot see very well out of that eye and have double vision when reading. With these problems in mind, would I be suitable for eye surgery?
      Many thanks.

      • Bethany Kingsley 23/09/2016 at 16:41

        Hi Heidi,
        Thank you for your email. As you have an amblyopic left eye, you would not be able to achieve total independence from glasses.

        The double vision may exclude you from surgery but we wouldn’t know that until we had done a thorough examination to determine your suitability.We would need to go through some questions to give you some more information. Please call the clinic on 0207 224 1005 to speak to one of our Patient Care Coordinators.

      Would someone that is blind in one eye be considered for this procedure?

      • Bethany Kingsley 06/01/2017 at 09:43

        Hi Cody,
        Yes, someone who is blind in one eye could be a possible candidate for Laser Eye Surgery. You would have to have a full suitability consultation and of course the surgeon will go through all of the risks involved. Please call the clinic on 0207 224 1005 if you have any further questions.

      Hi I am suffering from keratoconus. Am I suitable for relex smile…

      • Bethany Kingsley 08/03/2017 at 07:52

        Hi Sunil,

        If you have Keratoconus, then it is unlikely that you would be SMILE. You would most likely need crosslinking to strengthen the Cornea. We offer a newer procedure called PiXL as well as conventional crosslinking. If you would like to find out more, please call 020 7224 1005.

      Can laser be done with Reis bucklers dystrophy

      • Bethany Kingsley 02/08/2017 at 06:08

        Hi Jean,
        Are you looking to improve the erosions or refractive correction? If your refraction then laser eye surgery may not be suitable for you. The dystrophy causes recurrent erosions. It may be that therapeutic surgery will be recommended for the recurrent erosions. Unfortunately, without examining your eyes, we are unable to give you a definitive answer as to
        Whether you would be suitable. Please feel free to contact the clinic on 020 7224 1005.

    7. Padma Aon Prakasha 23/08/2017 at 10:59

      Hi, I Am astigmatic, short sighted, and was refused previous Lasik eye surgery a few years ago. Would SMILE be appropriate for me?

      • Bethany Kingsley 04/09/2017 at 06:21

        Hi Padma,
        We would need to know a little more about why it was that you were unsuitable. The best way to get these questions answered would be to chat with one of our experienced Patient Care Coordinators on 020 7224 1005.

    8. Larissa 21/09/2017 at 15:15

      I was told I am not suitable for LASIK becuase my cornea are on the thin side and was recommended to do PRK. Would I be a candidate for SMILE? Does SMILE have the potential side effect of cornea wavyiness/bumpiness like LASIK? My RX is -7 and -7.5

      • Bethany Kingsley 21/09/2017 at 16:22

        Hi Larissa,
        Thanks for your comment.
        We would first need to know your corneal thickness measurements, however the best way to get your questions answered is to chat with one of our experienced Patient Care Coordinators on 020 7224 1005.

      I have a turn in my left eye that was noticed when I was 3yo, and have been wearing glasses full time ever since. My vision is very poor for my age, and my left eye is considerably worse than my right. I would be willing to try anything make my eyes ‘straight’ as I hate how noticeable my condition is and how it looks in photographs etc. My condition is hereditary and was passed down to me by my mother, who also had a lazy eye, but hers was corrected surgically when she was 11, 39 years ago. I’ve been told over the years that there’s nothing can be done. I find this hard to understand and accept given the advances in ophthalmics and am hoping you may have a procedure that would help me??

      • Bethany Kingsley 09/01/2018 at 10:33

        Hi Rachel,
        Laser Eye Surgery is unfortunately not able to refine the vision further, due to the underdeveloped pathways from when you were a child. While laser eye surgery cannot specifically treat a lazy eye, suitability for laser surgery with an aim of improving overall vision will depend on the best corrected visual acuity of the lazy eye. Many patients with mild lazy eyes can have successful outcomes after laser surgery. If you would like further information about your options, call 020 7224 1005 to speak to a Patient Care Coordinator.
        Many Thanks,
        London Vision Clinic

    10. Jess Wright 09/03/2018 at 17:18

      I’m very interested in the SMILE procedure. I suffer with dry eyes and find I can only tolerate contact lenses for a few hours. Would I be a potential candidate for SMILE? I am short sighted -2 and -2.5.
      Kind regards

      • Bethany Kingsley 12/03/2018 at 10:04

        Hi Jess,

        Being a minimally invasive procedure, ReLEx SMILE makes it possible to treat patients with contact lens intolerance, very high prescriptions, drier eyes, and thinner corneas. To find our your suitability, you would need to come in for a full eye health examination, in your initial consultation. To find out more, please call our team of Patient Care Coordinators on 020 7224 1005.
        Kind Regards,

      Hi,my dyopters are -8 and -6 myopia with astygnatism.I have glases since I was 9yo,can I have this surgery?I am 32.Thanks

      • Bethany Kingsley 13/03/2018 at 09:01

        Hi Daniela, we can now operate and correct Astigmatism, however, it restricts the treatable parameters. So, to find out what your best corrected vision could be, we would need you to come in for a full eye health examination.
        If you would like to know more, call our Patient Care Coordinators on 020 7224 1005.

    12. D B 10/07/2018 at 10:50

      Hello, I came for an examination a few years ago but was told due to being long-sighted (+3 and +2.5 with some astigmatism) I wasn’t suitable for your treatments at the time. Would this procedure be more suitable?

      • Bethany Kingsley 16/07/2018 at 11:01

        Hi DB, we are able to treat both long and short-sighted patients with astigmatism. It is difficult to comment further without seeing you so would suggest that you get back in touch with us by calling 020 7224 1005. Your Patient Care Coordinator will be able to discuss your options with you in more detail, and should you wish to come for another consultation, they can arrange this.
        Kind Regards,
        London Vision Clinic

      Hi, does ReLEx SMILE use a laser that can be programmed with aspheric treatment profiles? My low light vision is not great and elsewhere in your site you say “lasers using ‘aspheric treatment profiles’ will be safer with respect to night vision. Some laser systems are so well designed that they can even improve contrast sensitivity and night vision in some patients.”

      • Chloe Lay 03/01/2019 at 13:06

        Hi David, thanks for your comment.
        ReLEx SMILE treatment aims to reduce night vision disturbances/low light vision concerns by treating a larger optical zone. This is something which your Optometrist will be able to discuss with you in more detail during your full eye health examination. Should you have any further questions, you can call us on 020 7224 1005.
        Best wishes,
        London Vision Clinic

      Hi. My eye-sight was fine for most of my life. Never needed any glass ever and now I’m 56 and I need reading glasses and glasses for distance.
      I don’t think I have any “problems” with my eyes apart from now being near and far sighted.
      I have a fear of sharp thing and eyes so the least invasive proceedure would be best. Do you think I would be a candidate for the new generation of eye surgery? ReLEx SMILE?

      • Chloe Lay 23/04/2019 at 16:12

        Hi Mark,

        We recommend that you call to speak with one of our Patient Care Coordinators on 020 7224 1005.
