Stay tuned as we progressively expand on each of these topics.

What are Orthokeratology Lenses?

Orthokeratology lenses (Ortho-K lenses) are unique, gas permeable contact lenses that have gained global recognition for their effectiveness in correcting refractive errors. Unlike standard lenses that are typically worn during the day, Ortho-K lenses are worn overnight while you sleep.

A remarkable science behind these lenses is the process they employ to correct vision – a process akin to orthodontics for the eyes. They work by gently and temporarily reshaping the cornea – the clear, outer layer of the eye – to correct myopia (nearsightedness), hypermetropia (farsightedness), and astigmatism. Essentially, these lenses operate in a non-surgical, reversible way to manipulate the eye’s structure and correct vision.

Ortho-K lenses’ nightly use and their removal upon waking provide the wearer with clear vision during the day without the need for glasses or conventional contact lenses. This quality of life improvement is especially significant for those who lead active lifestyles or work in environments where glasses or contact lenses may be inconvenient or even unsafe.

Dr. Edward Boshnick, a pioneer in the field of Ortho-K lenses, has utilized this revolutionary technology to provide thousands of patients with improved vision. His dedication to this specialized field and his commitment to patient care have solidified his reputation as a trusted source of Ortho-K lenses.

Understanding the functioning of these lenses is as fascinating as it is intricate. In the next section, we will delve into the science that enables Ortho-K lenses to reshape the cornea and provide improved vision.

The Science Behind Orthokeratology

Orthokeratology, or Ortho-K, harnesses the concept of corneal reshaping to correct vision. This revolutionary technology operates on the same principle that enables braces to straighten teeth over time. However, unlike the months or years required for orthodontics, Ortho-K lenses perform their reshaping work as you sleep, providing clear vision upon waking.

The cornea, the eye’s clear front layer, is responsible for focusing most of the light entering the eye. When the cornea’s shape is perfect, light accurately focuses onto the retina at the back of the eye. However, in cases of myopia, hypermetropia, or astigmatism, the cornea’s shape causes light to focus either in front or behind the retina, resulting in blurred vision.

Ortho-K lenses gently mold the cornea’s shape to allow light to focus correctly onto the retina. These lenses are custom-made using precise measurements from a corneal topography scan, ensuring a perfect fit. As the cornea is highly flexible and adaptive, the changes imposed by Ortho-K lenses are temporary and reversible, making this method a safe and non-surgical alternative to other vision correction procedures such as LASIK.

But how can changes to the cornea occur overnight? The answer lies in a process called corneal epithelial remodeling. The epithelium, a soft, outer layer of the cornea, is highly adaptive and can change its shape under the gentle pressure of Ortho-K lenses. These lenses create a tear film layer beneath the lens and the corneal surface, generating hydraulic forces that reshape the cornea.

Dr. Edward Boshnick’s expertise in Ortho-K is grounded in a deep understanding of this science. His proficiency in using state-of-the-art corneal topography devices ensures that patients receive Ortho-K lenses that are perfectly tailored to their individual needs.

The benefits of Ortho-K lenses extend beyond their primary function of correcting refractive errors. In the next section, we will explore these benefits in more detail.

Orthokeratology offers a range of benefits that contribute to its rising popularity. These advantages span across age groups, accommodating both adults and children in their pursuit of clear, unaided vision.

1. Myopia Control in Children: Myopia, or nearsightedness, is a growing concern among children worldwide. Studies have shown that Ortho-K lenses can effectively control the progression of myopia in children, making them an essential tool in proactive eye care.

2. Freedom from Daytime Eyewear: For many, the appeal of Ortho-K lenses lies in their promise of clear, unaided vision during the daytime. Once the Ortho-K lenses have done their work overnight, users can enjoy a full day of clear vision without the need for glasses or contact lenses. This benefit is particularly advantageous for athletes and those who work in challenging environments where eyewear can be a nuisance.

3. Non-Surgical Alternative to LASIK: While LASIK surgery offers a permanent solution to refractive errors, not everyone is a suitable candidate for the procedure. Furthermore, the thought of surgical intervention can be daunting for some. Ortho-K provides a safe, non-surgical, and reversible alternative to LASIK, delivering comparable results without the risks associated with surgery.

4. Comfort: Traditional contact lenses can cause dryness and discomfort, especially in windy or dusty environments, or after prolonged screen time. With Ortho-K lenses worn during sleep, users can avoid these daytime discomforts associated with regular contact lens use.

5. Improved Quality of Life: Ultimately, Ortho-K lenses enhance users’ quality of life by providing the freedom to enjoy daily activities without the limitations imposed by eyeglasses or daytime contact lenses. They allow for unrestricted participation in sports, improved peripheral vision, and the ability to see clearly from the moment of waking.

Dr. Edward Boshnick’s practice at Global Vision Rehabilitation Center is driven by the goal of improving patients’ lives through advanced vision correction methods like Ortho-K. His expertise and patient-centric approach ensure that each patient benefits maximally from their Ortho-K experience.

In the following section, we’ll compare Ortho-K lenses with other popular vision correction methods.

Orthokeratology Lenses vs. Other Vision Correction Methods

Orthokeratology lenses stand out as a unique vision correction solution, especially when compared to other popular methods such as eyeglasses, regular contact lenses, and LASIK surgery. Let’s explore how Ortho-K lenses fare in comparison to these alternatives:

1. Eyeglasses: The most traditional method of vision correction, eyeglasses are a simple and cost-effective solution for refractive errors. However, eyeglasses can be inconvenient for sports, can distort peripheral vision, and do not slow the progression of myopia in children. Conversely, Ortho-K lenses offer an unobstructed field of view, are great for sports enthusiasts, and have been shown to control the progression of childhood myopia.

2. Regular Contact Lenses: Like Ortho-K lenses, regular contact lenses free the wearer from glasses. However, they must be worn during the day, which can lead to dryness, discomfort, and potential infection risk with improper handling. Ortho-K lenses are worn at night, reducing the chances of dry eyes and allowing for a glasses-free and contact lens-free day.

3. LASIK Surgery: LASIK provides a long-term solution to refractive errors by surgically reshaping the cornea. While LASIK has a high success rate, it is not reversible and carries the risks associated with surgery. On the other hand, Ortho-K is non-surgical and completely reversible. If you stop wearing your Ortho-K lenses, your cornea will gradually revert to its original shape.

Orthokeratology lenses bring together the best aspects of these vision correction methods while minimizing their drawbacks. They are particularly compelling for those who seek a non-surgical approach to vision correction that still allows for unaided daytime vision.

Dr. Edward Boshnick’s Global Vision Rehabilitation Center offers Ortho-K therapy as a prime choice for patients seeking an advanced, non-surgical solution to their vision problems.

In the next section, we delve into the ideal candidates for Orthokeratology.

1. Initial Discomfort: When you first start wearing Ortho-K lenses, you may experience slight discomfort or foreign body sensation. This feeling typically diminishes as your eyes adjust to the lenses, usually within a few days. If discomfort persists, contact your eye doctor as soon as possible to have your lenses checked and adjusted if necessary.

2. Visual Fluctuations: In the early stages of Ortho-K therapy, some people may notice fluctuations in their vision, especially towards the end of the day. This fluctuation usually resolves as the cornea adapts to the reshaping process and as your wear schedule is optimized.

3. Halos or Glare: Some Ortho-K wearers may notice halos or glare around lights, particularly at night. This is more common in the initial stages of Ortho-K therapy and tends to improve with time.

4. Infection: Though rare, there is a risk of eye infections with any type of contact lens wear, including Ortho-K. This risk can be significantly minimized by following proper lens care and hygiene protocols.

Proper care and regular follow-ups with your eye care professional can effectively manage these potential complications. Dr. Boshnick emphasizes the importance of regular cleaning and disinfecting of lenses, proper hand hygiene, and appropriate lens storage to all his patients. He also encourages immediate consultation if any signs of infection—such as redness, pain, excessive tearing, or sensitivity to light—occur.

To put it simply, potential complications should not deter you from considering Ortho-K as an effective and safe vision correction method. With the guidance of an experienced practitioner like Dr. Boshnick, you can enjoy the benefits of Ortho-K with peace of mind.
