Laser Eye Surgery For Very High Prescriptions

It’s a commonly held belief that Laser Eye Surgery is not an option for those with very high prescriptions, and that the only option is synthetic lens implants.

Whilst this can be the case at some clinics, it is usually a matter of the clinic lacking the technology or expertise to treat very high prescriptions, rather than of the patient being clinically unsuitable.

London Vision Clinic is different.

We’ve been treating patients with very high prescriptions for many years. We’re able to do this because of our world-class technology, the expertise of our surgeons, and the fact that we believe in giving every patient the best possible outcome – regardless of the amount of work it takes.

Our pioneering approach to developing ‘High Profile’ treatments has established London Vision Clinic as world-leaders in treating high prescriptions.

Professor Dan Reinstein, lead laser eye surgeon at London Vision Clinic, had this to say about the treatment of patients with high prescriptions with our ReLex SMILE procedure:

“Generally speaking, traditional Laser Eye Surgery can only correct prescriptions up to a maximum of between -8 and -10.

This is because in traditional Laser Eye Surgery, the surgeon cuts a circular flap from the surface of the cornea and removes tissue from the exposed cornea, reshaping it to remove refractive errors.

The higher the refractive error (ie the higher the prescription), the more tissue needs to be removed to correct it – therefore the cornea must be thick enough. Most people simply don’t have thick enough corneas to allow enough reshaping to be done to correct high prescriptions – making them unsuitable for traditional Laser Eye Surgery.

With ReLEx Laser Eye Surgery treatment at London Vision Clinic, people with thin corneas and those with prescriptions of higher than -10 can be treated, because we do not make a flap from the corneal surface.

Instead, we remove the tissue from the centre of the cornea through a tiny hole made at the side of the eye, leaving the front of the cornea intact.

ReLEx SMILE Laser Eye Surgery uses an extremely precise laser to create micro-pulses beneath the surface of the cornea. The patient feels virtually nothing during the surgery because the eye is numb from anaesthetic drops and any contact with the eye is very gentle.

What’s more, the technique can significantly reduce or even eliminates the common side-effect of post-operative dry eye, which people often experience temporarily after traditional Laser Eye Surgery.”

      Hi Gwen,

      Apologies for the delay getting back to you. To clarify, did you mean your prescription is -3.0?

      Kind regards,

    Hi, my prescription is -14.50 in both eyes and I also have astigmatism. Would I be suitable for treatment in any way?

    Thanks

      Hi Dominic,

      In order to assess your likely suitability for laser eye surgery, we would need to speak to you on the phone and ask you some more detailed questions about your eyes, and also about what you hope to achieve from treatment. Suitability can depend not only on your prescription itself, but also on other factors relating to your ocular anatomy and visual quality.
      As a first step, the best thing would be for you to call us on 020 7224 1005, or email details of your most recent glasses prescription to info@londonvisionclinic.com.

      We look forward to hearing from you.

      Kind regards,

      London Vision Clinic

    Hi, what’s the minimum age to do this procedure? I’m only 16 and have severe myopia already, what’s the highest prescription this can treat?

  5. Bilal 05/02/2017 at 11:10

    I am 22 years old, ill wait another year to research;
    my latest rx: R:-5.00/-0.75X7
    L: -4.50/-0.50X3

    I think my pupil diameter is 7.8mm
    I do have slight dry eye but its only noticeable when around air-con.

    I know a lot of factors effect suitability, but i just want to know, which treatment do people with my RX, get.

      Hi Bilal,
      I am afriad that we cannot diagnose treatments without seeing a patient. Based on your prescription I see no contraindicators to you have surgery at the stage. It would ultimately be up to the surgeon as to wat procedure would get you the best possible outcome in the safest possible way. If you have any further questions- please call the clinic on 0207 224 1005.
      Thanks,
      London Vision Clinic

    Hi my prescription is +8 with astigmatism. Will i be legible for laser surgery.

    • Bethany Kingsley 01/02/2018 at 10:10

      Hi David, your treatment is in the upper limits of what we can treat with a laser. We do have great experience treating high prescriptions and those previously deemed unsuitable, so we may find an alternative treatment more suitable for you. Give a Patient Care Coordinator a call to discuss more on 020 7224 1005.
      Many Thanks,
      LoVC

    Hi,
    I have a prescription of +7.5 with moderate astigmatism in my left eye and a low amount in my right eye. Would this be within the expected limits for treatment?
    Thanks

    • Bethany Kingsley 14/08/2018 at 12:03

      Hi Rebecca,
      Thanks for your message. I would recommend calling to speak with a Patient Care Coordinator on 020 7224 1005 to discuss your options and book in an initial consultation, where your suitability can be determined.
      Kind Regards,
      London Vision Clinic
