Your Suitable Prescription for Laser Eye Surgery

24 Dec 2019

Laser eye surgery is a widely popular treatment that helps to improve your eyesight, depend on visual aids and decrease things such as the dry eye. This type of surgery may free up for engaging in all kinds of activities, events and sports that you cannot even think of doing without wearing glasses or contact lenses.

Here are some questions that will help you to know if you are the right candidate for performing laser eye surgery. Also, you can consult with the doctor to know your eligibility criteria for the procedure.

  • Are you above 18 years?
  • Are you in good health condition?
  • Can you see properly when wearing glasses?

If you answer to these questions is “yes”, then this means you are suitable for the treatment. One of the reasons is that you may have extremely high of a prescription that cannot be treated with laser eye surgery. Also, you can also have very low of a prescription. There are certain factors you need to consider when determining if you are the right candidate for the treatment. One of them is the health condition of your eyes.

Reasons you are not suitable for laser eye surgery

The most suitable way to know is by performing a comprehensive consultation with an eye expert. This way, you can get a clear idea of whether you are suitable for a Laser Eye Surgery or not. Some reasons you might not be suitable for the treatment are the following:

  • Stability of your prescription – The reputed clinics may ask you to provide a stable prescription for at least twelve months to two years, before undergoing the procedure. So, teenagers and young people are not considered to be a suitable candidate for treatment.
     
  • The thickness of your corneas – LASIK is the most common procedure that requires a cornea which is not very thin or misshapen to perform safely. Laser Eye Surgery that has thin corneas might compromise the results leading to vision worsening. As it does not involve creating a flap-like LASIK, the new ReLEx SMILE treatment might provide an alternative in such cases.
     
  • The size of your pupil – If your pupils are abnormally large, undergoing LASIK surgery in London might increase the risk of experiencing side effects such as halos and glares. Hence, performing sufficient pupilometry testing in the screening phase is of vital importance.
     
  • Your age: Your age plays an important factor for some changes in your eye. So, laser eye surgery is not suggested for the ones who cannot be guaranteed long term results. However, there are other options too like PRESBYOND® Laser Blended Vision that are a better choice in this case.
     
  • You are pregnant or lactating – Some kind of hormonal shifts at the time of pregnancy may lead to fluctuation and trigger eye symptoms. The medications used both during and after the treatment might be risky for your child. Due to these reasons, it is advisable to wait for several months after lactation and pregnancy to undergo the treatment.
     
  • Your overall eye health – It is important for the doctors to know how stable your eye health is. Only then, they will be able to know how suitable you are for laser eye surgery. For example, when you have dry eye syndrome, cataracts or glaucoma, there are different eye conditions that may have an impact on your stability. Some of these are the following:
     
  • Blepharitis or eye infections – Your eyes should be completely clear of infection.
  • Increased internal eye pressure – Eye pressure should be kept under control.
  • Epilepsy, MS – This will depend on the status of your health condition.
  • Diabetes – It is okay if you can keep it under control with healthy retinas.
  • Very large pupils who have a higher correction.
  • Your prescription is low and you do not need astigmatism.
  • A prism or squint that cannot be corrected with contact lenses
  • Corneal dystrophy
  • Iritis
  • Herpes of the eye
  • Blindness in one eye or partial sightedness

Your overall health – Other than good eye health, it is also important to improve your general health condition. For example, you might not be suitable to undergo laser eye surgery when you suffer from:

  • Rheumatoid Arthritis, Lupus, SLE
  • Crohn’s or collagen disease
  • Keratoconus
  • Macular degeneration
  • Optic nerve damage

If you fall under any of these categories, then this does not mean you are not suitable. In general, the better and more stable your health condition might be, the greater your chances will be of becoming a good candidate.

Does your prescription fall under the treatable range?

With health bases covered worldwide, you can now find out if your prescription falls under the treatable range. In order to be eligible for LASIK, your prescription should fulfil the following criteria:

  • Near about 8.0 dioptres of nearsightedness
  • Almost 3.0 dioptres of astigmatism
  • Nearly 9.0 dioptres nearsightedness along with astigmatism
  • The amount of nearsightedness with or without astigmatism in the eye did not change by at least 0.5 dioptres during the year before your pre-operation examination.

If your prescription passes beyond these levels, then many reputed clinics would rule out laser eye surgery as a suitable option for you.  They might even suggest lens surgery such as implantable contacts to be an alternate option. However, there are other treatments available too at a laser eye surgery clinic in London that may be more suitable for your needs.

What will happen if your prescription is not meant for laser eye surgery?

Truly speaking, laser eye surgery may correct prescriptions only by up to a maximum of between -8 and -10. This is because the higher the prescription is, the more tissue will have to be removed to get it corrected.

The cornea consists of a restricted amount of tissue that should be thick enough to allow “high profile treatments” so that it can take place. However, most people do not have thick corneas to enable the necessary reshaping, and so, they are not suitable for traditional LASIK treatment.

Today, LASIK is considered to be one of the main options available for correcting different kinds of severe eye problems. When it is about treating presbyopia, there is PRESBYOND® Laser Blended Vision. On the other hand, when you need to treat high prescriptions, then there is the revolutionary ReLEx SMILE treatment.

SMILE can help in treating people with prescriptions that are higher than -10 and those who have thinner corneas. The main reason is your smile does not need to be a flap in the corneal surface for using an advanced one-step technique and a femtosecond laser for the entire treatment.

Thus, it is extremely important to find out if you are the right candidate for laser eye surgery. You may book an appointment with our friendly team of clinic coordinators or visit us for your no-obligation consultation.
