MYOPIA

 

What is myopia?

Myopia is a vision impairment that manifests when far-away objects look blurry to the patient. Myopia starts to develop around 6-8 years of age and progresses as the patient grows, generally up to the age of 15-16, though it can progress after this point.

The factor that determines the total myopia that your child will have as an adult is the speed of progression of the myopia (dioptres which grow every year) and the number of years over which their myopia continues to progress.

What are the consequences of myopia for your children’s eye health?

In children, certain eye problems can be related to the degree of myopia as an adult. In other words, the more myopia someone has as a child, the greater the chance of developing eye diseases such as detached retina, glaucoma, myopic maculopathy, etc.

What is high myopia?

A person is considered to have high myopia when their degree of myopia reaches or surpasses six (6) myopia dioptres.

It is a good idea to use myopia correction methods such as orthokeratology, which have been shown to slow down the progression of myopia in growing children.

Can I see equally well with contact lenses as with glasses?

Yes, vision with contact lenses is just as good as with glasses.

Children with high degrees of myopia are likely to see better with contact lenses.

The ALEXA AR Toric design also allows users with astigmatism to enjoy excellent vision when their myopia is corrected with orthokeratology.

What are the advantages of using contact lenses in children and teenagers?

Contact lens use in children and teenagers has certain advantages that directly influence their personal development:

1. Quality of vision.. Contact lenses provide broader peripheral vision than glasses, allowing children to see the things around them more easily. If your child has high myopia, they are likely to see better with contact lenses than with glasses.

2. Freedom.. Contact lenses are ideal for doing sport as they allow the wearer to focus on the game and not worry about breaking their glasses. Contact lenses and sport are an excellent combination.

3. Self-esteem.. Numerous studies seem to indicate that children who wear contact lenses have higher self-esteem and more confidence.

4. Responsibility.. Children must commit to taking care of their contact lenses and following all the hygiene measures. This is beneficial to their personal development and allows them to feel that the adults in their life trust them.

5. Myopia control. Orthokeratology contact lenses have been shown to stop the progression of myopia, protecting the future visual health of children.

What is the minimum age for wearing contact lenses?

There is no minimum age for using contact lenses. This will depend on the responsibility and maturity of the child. Wearing contact lenses requires great care and excellent hygiene, as these are absolutely essential for safely handling contact lenses.

At early ages, it is important to use myopia correction methods that are capable of controlling the myopia, such as orthokeratology. This helps impact the progression of the myopia, preventing it from progressing to a higher degree.

It is most common for children to start handling contact lenses at the age of six (6), as long as they are capable and mature enough to do so. At this age, once they have been taught how, children can become responsible for their contact lenses. In general, prior to this age, parents tend to responsible for helping them. Even so, it is important to remember that, particularly at the start, this should be done under adult supervision to ensure a safe procedure.

Are contact lenses safe for children?

Contact lenses are equally safe for all users, regardless of whether they are adults or children.

ALEXA AR are contact lenses that are customised to each user according to their vision parameters, thereby guaranteeing enhanced comfort and safety during use.

Of course, hygiene and care routines must be adequately followed to ensure safe use.

Washing and drying the hands before putting in or taking out your contact lenses, proper storage in contact lens solution (for reusable lenses) or disposal in the rubbish (for daily single-use lenses)… children are capable of learning and embracing these steps much faster than we can imagine. Once they get used to the routine, contact lens use won’t entail any issue for their eye health.

Do contact lenses break easily?

The estimated number of broken contact lenses is under 1%. The majority of breakages occurs when trying to remove contact lenses due to getting pinched by the fingernails or getting stuck on the lens case when putting them in.

What should I do if my contact lenses fall on the floor?

Check that they are intact and not broken. Next, you should assume that they have been contaminated. Clean them with a care solution and then rinse. If you cannot clean your lenses right away, place them in their lens case until you can clean them adequately.

If you have questions about the condition of your contact lenses, consult your optician-optometrist.

How do I use my contact lenses for the first time?

The first step toward using contact lenses is to visit your optician-optometrist.

• Your optician-optometrist will show you how to put them in and take them out and will supervise the fitting process. Follow the instructions of your optician-optometrist during all steps of the fitting process.

• At first, children may be somewhat nervous about putting in their contact lenses. However, they will quickly get used to the process and incorporate it into their routine. Be patient and make them feel safe and confident. Reassure them that they can do it. Children learn far faster than adults!

• Putting in and removing contact lenses requires some practice at the outset, and it is normal not to get it right the first time, but you will figure it out quickly!

• Follow the indications of your optician-optometrist regarding the number of hours of contact lens use per day. To ensure safe contact lens use, it is very important that you follow the instructions given by your optician-optometrist.

• Follow the indications of your optician-optometrist regarding contact lens care. To ensure safe contact lens use, it is very important that you follow the instructions given by your optician-optometrist.

And obviously, kids are still kids: A parent must always supervise the process and be present with the child to ensure they are calm and relaxed!

 

ORTHOKERATOLOGY

What is orthokeratology or Ortho-K?

Overnight orthokeratology, also called Ortho-K, is a non-surgical solution (does not require surgery) for correcting myopia in children, teenagers and adults. This treatment uses contact lenses while the person is sleeping to modify corneal curvature and correct their vision.

For whom is it intended?

Orthokeratology or Ortho-K is an ideal solution for children, teenagers and adults with the following conditions:

 

• Users with myopia, hypermetropia and astigmatism.

• Growing children with myopia.

• Users who want to be able to see during the day without using contact lenses or glasses.

• Users who want to practise sport with total freedom.

• Users who don’t want to undergo refractive surgery.

• Users not contraindicated for contact lens use.

When is orthokeratology contraindicated?

After completing a feasibility study for fitting the lenses, your optician-optometrist will let you know whether or not you are a suitable candidate.

This treatment is contraindicated in certain cases, for example, inflammatory or infectious conditions in the anterior chamber of the eye, dry eye syndrome, corneal irregularities, eyelid conditions and diabetes, as patients may have decreased corneal sensitivity and healing.

The most important factor for treatment is that the patient must be fully committed to the indications given by their optician-optometrist in order to guarantee treatment safety. Therefore, if a patient cannot or does not want to comply with these instructions, this treatment is strictly contraindicated.

How long does treatment last?

Orthokeratology or Ortho-K lenses work overnight while you are sleeping to ensure correct vision during the day with no need for glasses or contact lenses. For users to be able to see during the day, they must wear their orthokeratology lenses while they sleep.

How long does it take for orthokeratology lenses to take effect?

When starting orthokeratology treatment with your optician-optometrist, orthokeratology lenses start working from the first use. However, your treatment will stabilise, that is, your myopia will be fully corrected over the course of the entire day over the next 5-10 days, depending on your degree of myopia.

How long does the effect of orthokeratology lenses last?

With orthokeratology lenses, your myopia will be fully corrected throughout the entire day following overnight use. At night, when you go to bed, you must put in your lenses so they can continue working while you sleep.

Are there orthokeratology lenses for all prescriptions and refraction errors?

Orthokeratology lenses correct myopia. Depending on the lens design, they can also correct astigmatism and hypermetropia.

Consult your optician-optometrist so they can offer you options according to your refractive parameters.

How often should I change my orthokeratology lenses?

Each lens manufacturer defines a replacement period for their contact lenses. In the case of ALEXA AR®, lenses should be replaced with new ones every 12 months.

From what age can orthokeratology be used?

There is no minimum age for using contact lenses. This will depend on the responsibility and maturity of the child. Wearing contact lenses requires great care and excellent hygiene, as these are absolutely essential for safely handling contact lenses.

It is important to control myopia from an early age to monitor the progression of the myopia, preventing it from progressing to a higher degree.

It is most common for children to start handling contact lenses at the age of six (6), as long as they are capable and mature enough to do so. At this age, once they have been taught how, children can become responsible for their contact lenses. In general, prior to this age, parents tend to responsible for helping them. Even so, it is essential to remember that, particularly at the start, this should be done under adult supervision to ensure a safe procedure.

What if I don’t get enough hours of sleep?

Orthokeratology treatment takes effect during the initial hours of sleep. In general, you don’t need to sleep for a long time in order to ensure stable vision throughout the entire day. At TIEDRA, we have ALEXA AR® users who work shifts, such as nursing staff, who have irregular sleeping routines, but their vision treatment remains stable.

Are they uncomfortable when sleeping?

Orthokeratology lenses are worn at night, so you won’t even know you are wearing them.

 

What happens if I forget to wear my lenses for a night?

Throughout the day you will gradually lose a little of your vision. When you go to bed at night and put in your lenses, the treatment will start again, and you will wake up with fully restored vision.

 

Is orthokeratology or Ortho-K a safe treatment?

Scientific evidence shows that orthokeratology or Ortho-K is just as safe as any other type of contact lens.
