Orthokeratology: The Temporary Solution to Vision Problems

Ortocheratologia: la soluzione temporanea ai disturbi visivi

If you are looking for a temporary solution to vision problems, you may want to consider orthokeratology, an effective therapy that does not require surgical intervention on the eye.

This treatment involves the use of customized, rigid or gas-permeable contact lenses during the nighttime. These lenses alter the shape of the cornea for a period of time even after their removal, ensuring the patient has clear vision throughout the following day.

Why is it performed?

Orthokeratology is a technique used to correct vision problems such as myopia, astigmatism, hypermetropia, and presbyopia. It is particularly effective for correcting myopia up to 5 diopters, astigmatism under 3 diopters, and hypermetropia between 2 and 3 diopters. Additionally, it seems to be particularly effective in preventing the progression of myopia in children and adolescents.

However, it is not a treatment suitable for everyone. To achieve the desired results, it is essential that the vision problem is not too severe, that the patient’s cornea is sufficiently soft to be shaped by the lens, that the tear film is in optimal condition, and that the patient does not have any specific allergies or sensitivities to the eyes. Only a specialist, after a thorough examination, will be able to determine if the patient is an ideal candidate for this treatment.

Orthokeratology works by using rigid, gas-permeable lenses worn at night, which shape the patient’s cornea. This way, during the day, the patient can see clearly without the need to wear any corrective lenses.

What does it involve?

Orthokeratological lenses represent an innovative solution for correcting vision problems without the need for glasses or contact lenses during the day. This type of lens works by slowly shaping the surface of the cornea through controlled pressure applied during the night. While sleeping, orthokeratological lenses correct the shape of the cornea, and their effect lasts even after the lenses are removed.

However, orthokeratological lenses are not suitable for all patients. Potential complications of orthokeratological lenses can range from eye discomfort and blurred vision to temporary corneal edema or infectious keratitis. However, these side effects can also occur with traditional contact lenses and are usually caused by poor lens hygiene.

In general, the use of orthokeratological lenses has the advantage of being temporary and reversible. If issues occur, the therapy can be stopped, and the patient can return to their initial condition. In any case, it is important to follow the optometrist's instructions and keep the lenses clean and in good condition to minimize the risk of complications.

Preparation for orthokeratology

In order to begin using orthokeratological lenses, it is necessary to undergo a thorough eye examination. This check-up is essential to assess the shape and curvature of the cornea and to design lenses tailored to the patient's characteristics.

It is important to emphasize that the eye examination should not only be done before starting the night lens therapy but also afterwards. In particular, after the first uses of the lenses, further check-ups are necessary to assess the eye's reaction to the therapy and, if needed, make appropriate adjustments to the lenses to optimize the treatment.

Additionally, it is crucial to carefully follow the optometrist's and the orthokeratological lens manufacturer's instructions regarding the daily usage duration and the frequency of lens replacement. This way, the risk of complications can be minimized, ensuring an effective and safe treatment.

How long does their effectiveness last?

Orthokeratological lenses work similarly to traditional corrective lenses, but with a prolonged effect that can last up to 24-48 hours after removal. The results may vary depending on the malleability of the patient's cornea. In some patients, the results may be noticeable after the first use, while in others, a longer period may be required to notice the effects. In general, the best results are typically achieved after about 1-2 months of consistent lens use. After that, if the desired results are achieved, the specialist may decide to reduce the frequency of lens use while maintaining the achieved outcome.

It is important to emphasize that it is essential to consult a specialist for a thorough eye examination before starting to use orthokeratological lenses and to conduct further check-ups during and after lens use to assess their effectiveness and consider any necessary adjustments.
