What is the worst thing that can happen after Laser Eye Surgery? [VIDEO]

The level of risk of Laser Eye Surgery broadly depends on two factors: Where you have the surgery, and the condition of your eyesight before having surgery.

As Professor Reinstein explains in the video below, there’s a range of competency in the Laser Eye Surgery field that means the chances of something going wrong can vary from clinic to clinic.

Rushed consultations, low-grade technology, a lack of expertise or experience; these are all things which heighten your risk and make choosing where to have your Laser Eye Surgery a crucial part of the process.

In the hands of an expert Laser Eye Surgeon using up-to-date technology, the chance of a slight complication occurring is around 1 in 1000, with the chance of a situation arising which the surgeon could not satisfactorily correct being closer to 1 in 30,000.

But we also need to consider you and your unique eyes and vision. There is no other way to do this than with a thorough consultation with an optometrist and a Laser Eye Surgeon, which will be carried out at any good laser eye clinic.

If, during your consultation, risk factors that could increase your chances of complications are discovered, your treatment plan would be adjusted accordingly and discussed with you in detail so you can make an informed decision.

In the short video below, Prof Reinstein puts the risks of Laser Eye Surgery into perspective and talks about the worst thing that can happen after surgery.

Prof Reinstein answers the question: What is the worst thing that can happen after Laser Eye Surgery?

As Prof Reinstein states, the reality of something going wrong is that there’s a very small chance of having a little bit of residual blurring, doubling, or something not right with the vision after surgery, that can’t be sharpened by wearing glasses.

In this case, the level of vision of the patient before the surgery will have been extremely blurry, and will still see vast improvements in clarity and acuity following the procedure.

And in addition to this, vision may well be completely restored by having a short enhancement procedure to fit it. All in all, the risk of it coming to this point is lower than one in a thousand—so less than 0.1%.

Managing the risks of Laser Eye Surgery

Laser Eye Surgery is incredibly safe, but no surgery is entirely without some level of risk. The fact is that an expert surgeon will have the knowledge to manage complications properly, and will often be able to correct any complications that do occur.

    What can happen if soap gets into my eyes or i accidently rub my eyes or splash water into them one month after laser surgery?

    • London Vision Clinic 10/03/2014 at 14:48

      Thank you for your questions surrounding laser eye surgery. If you have already had laser eye surgery, you should contact the clinic who treated you by phone, as we are unable to give you clinical advice if you are not a patient of ours, or if we do not know the specific details of your case. In theory, if a patient were to get soap in the eyes one month after laser eye surgery, it is unlikely that they would cause any problems. We would most likely advise them to flush their eyes with lubricating drops (plenty would have been supplied by the optometrist and surgeon). There is always someone on hand here at the clinic to answer your questions and help in any way, after surgery. You can resume showers within the first few weeks of surgery, so there are no problems with splashing water in the eyes. If you would like more information about laser eye surgery in general, please contact one of our Patient Care Coordinators on 020 7224 1005. We look forward to hearing from you.

    I recently had Smile Lazer with another clinic my prescription being -11 My correction should have bought me to -1.50 but the correction has regressed to -4. I am not at all happy and feel that my money has been wasted as I have endured thick glasses for years. Can any further corrections be made?

    • Bethany Kingsley 18/05/2016 at 16:23

      Hi Cheryll,

      It is possible, should you have sufficient corneal tissue to have further treatment yes. However, given that you have had the SMILE procedure you will not be able to have an enhancement with the same procedure. Please call us on 0207 224 1005 if you have any other questions.

    Hello. I got lasik in June of 2008. I have since noticed that during the past 6 to 9 months my eyesight is steadily worsening. What could be causing this? I have moved out of state and no longer live near my original place of treatment. Who should I seek for help? Thank you.

    • Bethany Kingsley 18/05/2016 at 12:49

      Hi Cassi,

      I would recommend you go for an eye check up. Depending on your age this could be the effects of Presbyopia. This is the process in which the lens inside the eye begins to lose it’s ability to change shape, and provide the ‘zoom’ required to focus from distance to near and back. Nobody is immune from this condition, and unchecked it inevitably means reading glasses, bifocals or varifocals. At the London Vision Clinic Laser Blended Vision is the treatment to rid patients of glasses when this process starts.

    • Bethany Kingsley 18/05/2016 at 12:44

      Hi Sara,

      Without assessing your eyes we wouldn’t be able to say. What was your prescription initially and may I ask your age? Feel free to send the information to as this will be more secure.

    • Bethany Kingsley 22/06/2016 at 07:26

      Hi Aaryan,

      As we specialise in laser eye surgery we would not be able to help in regards to your headaches. Have you contacted a more general medical unit or being to your GP to ascertain the cause of the headaches?

      Hi Aaryan,

      London Vision Clinic

  7. Aaryan 22/06/2016 at 10:13

    So my headache is not related with my lasik operation

    • Bethany Kingsley 22/06/2016 at 10:35

      Hi Aaryan,

      Unfortunately, we do not have enough information regarding your situation and your treatment. I would advise that you revisit the ophthalmologist who performed your surgery or visit a general medical unit to ascertain the cause.

  8. Aaryan 22/06/2016 at 11:30

    Is there any solution for my eyes pain from which I am suffering from last 1 year.

    • Bethany Kingsley 22/06/2016 at 11:49

      Hi Aaryan,

      I’m afraid we cannot give clinical information regarding your situation as we have no records for you and we would need to see you directly. Again, you would need to ascertain the cause of the eye pain and I would recommend contacting your surgeon to discuss.

      Thank you,

      Hi Tina,

      I am sorry to hear you are experiencing these issues. Every patient is different and it is important to ascertain the exact cause of the dryness to prescribe the most effective drops. I recommend you visit your surgeon or an ophthalmologist to get more precise information. Please do not hesitate to contact the clinic on 0207 224 1005 if you have any further questions.

    I had my eye surgery about a year ago but I have always been worried about hitting a ball with my head.
    I know there is always a risk when you hit a ball too hard with you head but I was just wondering, is there reason to be worried or can I hit a ball without danger to my vision??

    • Bethany Kingsley 01/11/2016 at 14:17

      Hi Ariel,
      Thank you for your comment. It is always important to avoid a blow to the head or be hit. It depends on the amount of force that you would be hitting the ball with. Having a ball on the head should not affect the vision, however, it is important to understand that if you are partaking in activities the risk of hitting the eye with the ball increases. Please call the clinic on 0207 224 1005 if you have any questions.

    • Bethany Kingsley 03/11/2016 at 07:40

      Hi Angelica,
      Considering you just had a procedure I would recommend you go for a check up and contact the clinic that did the treatment for you.

      Hi Gautham,
      We would need to fully assess your eyes, we cannot give medical advice when you are not a patient of ours. I would recommend you seek a second opinion if you are concerned. Try finding a specialist in Laser Eye Surgery in your area and visit them.

    I did a lasik surgery 4 years ago! Eyes were fine since then and I just had some sore/pain in eyes sometimes afterwards which could get better by eye drops. But, about 8 months ago I started to see trails following moving objects(for example if I move my hand I can see a trail following the motion, this happens all of the time especially in dim light). I contacted 4 different eye doctors and didnt get a proper answer for the cause. Only the last doctor told me that my Cornea has a irregular surface, and he thinks it can be a reason for this issue!Now my question is how the cornea can change its shape in time after a eye surgery which seemed to be succesful 4 years ago! Why my cornea has changed its shaped after 4 years? Please help! I am worried to do a second lasik to solve this and still in future get new changes in cornea!Really need your advice! im a female 28 years old. thanks

    • Bethany Kingsley 29/03/2017 at 11:30

      Thank you for your comments. The eye can changes shape with time. It is important to have an examination to ensure the changes are normal, a full specialist examination can determine the nature of the change. The most accurate way to determine the true nature of the changes is by using high frequency ultrasound, this is a specialist technique developed by Professor Reinstein. This can examine the nature of the shape change and assist in diagnosing the cause. The ‘trails following moving objects’ – known as illusionary palinopsia -are not associated with an irregular corneal surface. We would certainly reccomend a full ophthalmological and neurological work- up.

      • Nana1988 30/03/2017 at 10:17

        Hei Doctor,

        Thank you for the reply. So the full ophthalmogical test can reveal if this issue is due to Palinopsia or not? If it is Palinopsia, would there be any treatment for that? Thank you for the information you provid!

        • Bethany Kingsley 30/03/2017 at 16:11

          A full medical work up, will help to determine if the symptoms are related to and physical shape changes e.g. distortion of corneal shape, if related to distortion as suggested by the previous ophthalmologist there may be some treatment options to address the corneal changes, or reduce further changes.

  14. Kamal 12/02/2018 at 15:14

    I want to ask that can Myopia increase after two or three years of lasik even in early age?
    Is that possible?

    • Bethany Kingsley 15/02/2018 at 11:14

      Hi Kamal,
      Thanks for your comment.
      Occasionally an enhancement procedure may be required to correct this drift in vision after treatment, but many patients find this is not necessary and their vision remains consistent. Presbyopia, can set in when you reach your 40’s onwards, this can bring on the need for reading glasses. In this case, you may be suitable for Laser Blended Vision, which would tailor your eyes, one near-mid and the other, mid-distance.
      Kind Regards,
      London Vision Clinic

  15. Muugii 17/05/2018 at 01:35

    I had my lasik surgery 2 months ago. So i played basketball recently. Is that activity influence to my vision? Am worried after played basketball and left vision started blured. can i play basketball and football in the future? Is that activity influence to my vision?

    • Bethany Kingsley 17/05/2018 at 08:51

      Hi Muugii,
      Thanks for your comment. You should be able to resume usual activities within a few weeks after treatment, and for high impact sports, we recommend waiting 1 month. If you think your vision seems blurry, you should always see your eye doctor immediately.
      Many Thanks,
      London Vision Clinic

  16. Michelle Grundy 21/06/2018 at 06:25

    Had Lasek 4 weeks ago and vision still blurry. Consultant says it needs time to heal but I haven’t seen any improvement and I’m concerned it might be permanent.

    • Bethany Kingsley 25/06/2018 at 15:04

      Hi Michelle, thanks for your comment. Unfortunately, we are unable to comment fully without seeing you for a consultation. Individual recovery is unique to each patient and the healing and recovery process can differ. We would suggest you speak to your surgeon for further advice.
