The best and worst times to have Laser Eye Surgery

A bit like when you decide it’s time to move house and upgrade to a better one, for many people, there often also comes a time when they decide to ditch their glasses and upgrade to better vision.

But just like the house moving process, this isn’t a decision that comes at the snap of your fingers. First, you have to pay the mortgage off, remodel a few rooms, finish that extension, get enough time off work to do all the above, and not to mention find the perfect home and neighbourhood to move to.

In other words, some times are just more suited than others to make the change.

Inanimate objects and other people are difficult enough to manage. But trying to get complex and dynamic living organisms like the body to do what you want is even more challenging.

Ageing, disease, hormones, and genes affect us all differently, and finding those ideal moments for making a change to something like your eyesight is a skill in itself.

One reason for this is the body is somewhat happy chugging away in the background, autonomously regulating systems and repairing and growing while you go about your day none the wiser.

This can be while, on one level, you may feel ready for something, your body can have a completely different idea. And when it comes to Laser Eye Surgery, this scenario can sometimes be the case without even knowing it.

So, instead of getting all psyched up for your new vision and then going to the clinic to be told to come back again next year, we’re going to fill you in on some of the best and worst times to have Laser Eye Surgery.

The bad times: During pregnancy

Hormonal imbalances during pregnancy are more commonly associated with morning sickness and mood swings. But they also have a significant — albeit not so disruptive — effect on your vision.

During pregnancy, many women experience a reduction in their visual acuteness, tipping themselves and their prescriptions off balance. This often comes in the form of myopia or nearsightedness, causing blurry vision over a distance. But it can also be a shift to hyperopia or farsightedness.

And as if carrying a person-to-be with poor vision wasn’t enough, hormone imbalances are also known to cause dry eyes. All in all, this means Laser Eye Surgery is off the cards for those who are pregnant until at least a few months after nursing, when vision is once again stable.

When your eyes are still changing

While our bodies are still growing in our teens and early twenties, our eyes continue to grow and change along with them. Much like with pregnancy, this means your prescription and quality of vision can all the while be fluctuating, courtesy of your beloved hormones.

One of the main prerequisites for Laser Eye Surgery is having a stable prescription. And so if you are of an age in which these changes are still happening, you will typically be unsuitable for treatment — at least temporarily.

Luckily, our hormones and body do balance out over time. And so if you’re over 18 and your vision has been stable for over a year, you should have no problem with having the procedure. Simply bring your current glasses or contact lens prescription along to a consultation to confirm you’re ready for treatment.

If you have a dry eye condition

Due to our fast-paced digital lifestyles, dry eye syndrome is becoming an increasingly common condition. Unfortunately, as Laser Eye Surgery has a tendency to cause a little post-op dry eye, this means people with the condition can often be deemed unsuitable for treatment.

Post-op dry eye occurs as the procedure disrupts the nerves on the outer surface of the eye, resulting in a decreased sensitivity and a period of reduced tear production. But this is only typically the case for LASIK and older procedures, and so all is not lost for dry eye sufferers.

ReLEx SMILE — a new and revolutionary key-hole procedure — aims to make post-op dry eye a thing of the past. The SMILE treatment is minimally-invasive, can be performed in a fraction of the time of LASIK, and has an equally swift recovery.

SMILE, therefore, makes Laser Eye Surgery a suitable option for many who thought they were unsuitable: including those with dry eyes, thinner corneas, and very high prescriptions.

The good times: When you’re at the end of your tether

Maybe you’re just getting over an infection caused by contact lenses. Or maybe you’ve lost your second pair of glasses in the space of a month. Or maybe you’ve finally got around to booking that scuba diving holiday — whatever it is, there often comes a point when glasses and contact lenses have outlived their use.

Of course, they have their place, but in reality, they’re only meant to be a temporary form of vision correction. You may have even thought about Laser Eye Surgery in the past, but quickly dismissed it due to cost or fear.

But when you’re at the end of your tether, and you begin to do some proper research on the treatment, chances are you’ll find it’s a lot less costly and intimidating than you once thought.


There is never a better time to have Laser Eye Surgery than now. The sooner you have the surgery, the more years you have to enjoy the unique benefits it has to offer.

Having it now also brings the added bonus of being young and with eyes that tend to heal and stabilise a lot faster. That means the potential mild side effects are less of a concern, and the body is more effective at adapting to your new improved vision.

It’s important to note here that even if you think you’re an ideal candidate for Laser Eye Surgery and that now is the perfect time, where you have it is not a decision you want to rush into.

The first thing you want to consider is finding the right clinic for you. We recommend taking your time to do some background research, booking several consultations with different clinics to scope out everything from their credentials and experience, to their staff and their policies.

You’re only given one pair of eyes, so researching Laser Eye Surgery isn’t really a time you want to skimp on homework and opt for the cheapest option available. But you also don’t want to waste all your lunchtimes and evenings trudging through fine print and deceptive marketing campaigns.

If you’d like to find out if now is a good time for you to have Laser Eye Surgery or book a consultation with us, leave us a comment or give us a call us on 020 7224 1005.

    I wanted to have my eyes do a lasik surgery, but Now I’m actually confused if any of PRK or lasek would be a better choice to get the myopia of my eyes corrected?!!! The degree of the myopia is 1D.

    Thank you!

    • Bethany Kingsley 18/05/2016 at 12:25

      Hi Aralia,

      Everyone’s eyes are different. At London Vision Clinic our aim is to get you the best possible results and that means assessing your eyes for 3.5 hours initially to determine what the best treatment plan for you would be. Unfortunately, just knowing your prescription doesn’t give us enough information. We would need to assess your suitability fully and ascertain whether the PRK, Lasik or ReLEx SMILE treatment would be the best option. Please let us know if you need any other information by getting in contact on 0207 224 1005 or via

        Hi again,

        First, THANKS for the quick reply! I had already asked similar question with even more explanation in another medical website and they paid NO attention to it!!
        Well, I had actually another quest in which if infections caused by sinusitis could harm eyes any ways, esp after getting eyes done a surgery which means they will get much more sensitive?_I been suffering from a chronic sinusitis too for ages now (sometime it gets kind of infected even if I use anti bioethics for it).


        • Bethany Kingsley 20/05/2016 at 14:23

          Hi Aralia,

          Thank you for your comment. The sinusitis infections you are experiencing will not affect surgery. We would obviously want to make sure you had no signs of infection at the time of surgery. Any sinusitis infection you got after surgery would affect your eyes in the same way. It certainly wouldn’t preclude you from surgery. Please let me know if you have any other questions.

    I am 18 years old my number iswas -10.5 and -2.5 cylindrical since past 4 years . Suddenly this year it increased by 1 and now it is -11.5 . Is laser eye surgery possible for me

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

      Hi Jessica,

      We do treat patients as young as 18, however, to confirm if you would be suitable we would need to see you for a consultation. We would need as many previous prescriptions as you can get. It is certainly possible but we would need to make sure that it was the best option for you at this stage. Please let us know if you have any further questions or call the clinic to speak to one of our Patient Care Coordinators on 0207 224 1005.

    Hi. I am 49 and generally fit and healthy. My vision has deteriorated over the last few years and I am now struggling with my 3rd pair of varifocals. Would laser eye surgery be suitable for someone like me whose prescription seems to be changing at a (what seems to me) fairly rapid pace?

    • Bethany Kingsley 20/06/2016 at 15:32

      Hi Lucy,

      Thank you for your comment. It sounds like presbyopia has set in for you. This is the natural ageing of the eye and unfortunately means we all need to pop on the reading glasses at some point. Laser Blended Vision, a treatment pioneered at the London Vision Clinic can treat patients with presbyopia. Please follow this link for more information. If you would like to discuss more, please call the clinic on 0207 224 1005.

    I want to have Lasik Eye Surgery because I am sick and tired of lens I want a permanent solution but on the other hand I am very scared of eye laser surgery. Would laser eye surgery be suitable for me? Is it secure? Should I go for it?

    • Bethany Kingsley 09/11/2016 at 07:19

      Hi John, Laser eye surgery is a very safe medical procedure in terms in comparison. I am unable to say whether it is suitable for you without any information, you may want to call the clinic and get more information about your eyes on 0207 224 1005. One of our Patient Care Coordinators will be happy to go through any questions for you.

    • Bethany Kingsley 09/02/2017 at 09:08

      Hi Karnvir,
      Unfortunately, we are unable to determine your suitability with this information alone. You would certainly not be able to proceed while the uveitis was active. We would need to see you first for a consultation and most likely require blood tests to fully determine your suitability for laser eye surgery. Please call the clinic on 020 7224 1005 for more information.

      • Karnvir Singh 11/02/2017 at 07:43

        actually i am in india and cannot come to london for blood tests and various other tests.
        if i get rid of uveitis then can i have the treatment for eyes .actually i want to get rid of the spectacles as early as possible but safely. i am 17 yrs of age so please guide me as i dont know about these things much
        thank you

        • Bethany Kingsley 16/02/2017 at 11:49

          Hi Karnvir, We would be unable to advise if you would be suitable following Uveitis without assessing your eyes for a thorough examination. I would advise that you seek specialist help closer to home. However, as you are under 18 you should wait until proceeding with surgery.

    I am 30 years old. I also have a issue with my eyes that I wake up with itchy wet red eye. it is painful. I get a burning sensation. It only happens maybe one a month or in two months.

    Is eye surgery suitable for me?

    Thank you

    • Bethany Kingsley 22/06/2017 at 07:25

      Hi Hassan,

      We would need to assess your eyes and determine the issue you are having, from the information you have given, it is possible you could be suitable for laser eye surgery. As I said, you would need to have a full assessment to determine your suitability.

  7. Wayne 19/02/2018 at 11:47

    Hi, I am considering laser eye surgery within the next month or so. I have never worn glasses, my eyesight is not terrible. Do I need to wear prescription glasses for a certain period of time prior to laser surgery so that you get an accurate/stable prescription?..Or can laser eye surgery go ahead without the need of a prior prescription?

    Many Thanks

    • Bethany Kingsley 19/02/2018 at 13:21

      Hi Wayne, thanks for your comment.
      We normally ask for the previous few years worth of prescriptions as a way to track how your prescription has changed, and see it stabilising.
      If you do not need glasses, you should not start wearing them. Laser eye surgery aims to eliminate or reduce someones need for glasses, so we would need to find out more about your and your eyes in this instance.
      If you would like to discuss further with one of our Patient Care Coordinators, call us on 020 7224 1005.
      Kind Regards,
      London Vision Clinic

    I had laser eye surgery somewhere like 1995, approx 23 years ago (45 years old now) , and now i am back on glasses and contacts. can i have second laser eye surgery. or should i go for lens replacement or if there is any other kind of eye technology which i can use.

    kind regards

    • Chloe Lay 09/04/2018 at 15:35

      Hi there,
      Thanks for your comment. Yes, it is normal for someone to need a top-up procedure, to tweak the results many years later. We have a treatment called Laser Blended Vision, which addresses the need for reading glasses. You can read more about it here – This treatment compared to lens replacement is less invasive, lower risk, and can often be much cheaper. If you would like to know more, please give us a call on 020 7224 1005.
      Kind Regards,
      London Vision Clinic

    I am in my early 60’s and, like most people I have had to wear glasses since my 40’s due to natural aging of the eyes. My prescription has been fairly stable for the last couple of years and so I have been giving some thought to laser surgery. However, I have been advised by my GP that my eyes will continue to change as I move through the next couple of decades and should I reach my 80’s or later, there is a much enhanced risk of cataracts, surgery on which would cause a need for further laser treatment. Added to this he pointed out that due to the continued aging, I would probably still need to wear reading glasses.
    In that case I might as well continue to wear varifocals and get the best lenses that I can afford.
    Is my GP scaremongering or is laser surgery not ideal for the over 60’s for the reasons he stated?

    • Chloe Lay 09/08/2018 at 08:48

      Hi Graham, thank you for your comment.
      Presbyopia is a gradual change once you get into your forties, yes, although it is completely unique to each individual in terms of the progression and degree to which it may alter your vision. Should you have laser eye surgery, there is no link to causing cataract formation. I would recommend calling us to have a chat with our Patient Care Coordinators to discuss the various options you have on 020 7224 1005.
      Kind Regards,
      London Vision Clinic

    I am in my early 70 s I have myopia presbyopia and have dry right eye. Am I a suitable candidate for eye correction surgery. Thankyou.

    • Chloe Lay 11/03/2019 at 16:02

      Hi Helen, we have treated patients of similar prescriptions before but we would need you to come in for a full eye health examination to determine your individual suitability. To find out more, you can call to speak with one of our Patient Care Coordinators on 020 7224 1005.
      Many thanks,
      Chloe at London Vision Clinic
