Introduction:
Orthokeratology, also known as Ortho-K or corneal reshaping therapy, is a non-surgical vision correction procedure that involves wearing special contact lenses while you sleep, which are then removed when you wake up. The lenses reshape the cornea, the clear outer layer of the eye, to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Orthokeratology has been gaining popularity in recent years as a safe and effective alternative to traditional vision correction methods like glasses, contact lenses, and even laser eye surgery. In this ultimate guide to orthokeratology, we will explore everything you need to know about this revolutionary treatment.
The purpose of this blog post is to provide a comprehensive overview of orthokeratology, including how it works, who can benefit from it, the fitting process, risks and side effects, maintenance and care of lenses, cost, and insurance coverage. By the end of this guide, you should have a better understanding of whether orthokeratology is the right vision correction option for you.
What is Orthokeratology – what are the benefits of orthokeratology?
Orthokeratology lenses are worn overnight, then taken off in the morning, which gives you the ability to enjoy clear vision during the day without the need for glasses or contact lenses. This can be particularly advantageous for athletes or individuals who work in dusty or dirty environments, where glasses or contact lenses can be cumbersome or hazardous. Furthermore, orthokeratology has been shown to be an effective method of myopia control, which means it can slow down the progression of nearsightedness in children and young adults.
Is orthokeratology effective?
Orthokeratology has been around for many years, but has only recently begin to take off as mainstay option for vision correction. Early orthokeratology lenses were rigid and uncomfortable to wear, but modern lenses are made of breathable materials and are much more comfortable. In recent years, advances in computer technology have also allowed for more accurate and precise corneal mapping, which has improved the success rate of the procedure.
How does Orthokeratology Work:
Explanation of the Cornea and Its Role in Vision:
The cornea is the clear, dome-shaped layer that covers the front of the eye. It plays a crucial role in focusing light onto the retina, which is the layer of cells at the back of the eye that transmits visual information to the brain. When the eye does not focus light on the retina, the outcome are refractive errors like myopia, hyperopia, or astigmatism, it can cause blurry vision. Traditional vision correction methods like glasses and contact lenses work by compensating for unfocused light, but orthokeratology takes a different approach by reshaping the cornea itself!
How do Orthokeratology Lenses Reshape the Cornea:
Orthokeratology lenses are gas-permeable contact lenses that are worn while you sleep. The lenses gently reshape the cornea by applying pressure to the front surface of the eye. This pressure causes the cornea to temporarily flatten, which can reduce or change its refractive power and corrects the underlying refractive error. Over time, with regular nightly use of the lenses, the cornea retains its new shape, resulting in clear vision during the day without the need for glasses or contact lenses.
Benefits of Corneal Reshaping for Vision Correction:
One of the primary benefits of orthokeratology is that it provides temporary correction of refractive errors without the need for surgery such as LASIK, that can cause permanent changes, or daily use of corrective eyewear. The procedure is non-invasive, making it an attractive option for those who may be hesitant to undergo surgical vision correction. Additionally, orthokeratology has been shown to be an effective method of myopia control, which can reduce the risk of developing serious eye conditions like retinal detachment, glaucoma, and cataracts later in life. Orthokeratology can also be a great option for people who lead active lifestyles or work in environments where glasses or contact lenses may be inconvenient or unsafe.
Who Can Benefit from Orthokeratology:
Can orthokeratology correct myopia?
Orthokeratology can effectively treat a range of refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The procedure works best for people with mild to moderate myopia, but it can also be considered for those with more severe myopia.
Advantages of Orthokeratology Over Other Forms of Vision Correction:
One of the main advantages of orthokeratology over other forms of vision correction is that it provides temporary correction without the need for glasses or contact lenses during the day. This can be particularly advantageous for people who find traditional corrective eyewear cumbersome or uncomfortable. Orthokeratology can also be an effective method of myopia control, which means it may be especially beneficial for children and young adults who are at risk for developing severe nearsightedness.
Age Restrictions and Candidacy for Orthokeratology:
While orthokeratology can be an effective method of vision correction for many people, it may not be suitable for everyone. Candidates for orthokeratology typically have mild to moderate myopia or astigmatism, and they must be willing to wear the lenses most nights. There is no strict age limit for orthokeratology, but the procedure is generally not recommended for very young children, as their eyes are still developing. Additionally, people with certain eye conditions, such as keratoconus or severe dry eye syndrome, may not be good candidates for orthokeratology. The doctors at Prpic Eyecare Centre can evaluate your eyes and help determine if orthokeratology is a good fit for you.
How Can I Fit for Orthokeratology Lenses?:
Initial Consultation and Eye Exam
The first step in getting started with orthokeratology is to schedule an initial consultation with an optometrist who is experienced in fitting orthokeratology lenses. During this visit, the optometrist will conduct a thorough eye exam to evaluate your vision, eye health, and suitability for the procedure. They may also ask you about your lifestyle and habits to ensure that orthokeratology is a good fit for you. It is essential to rule out any contraindications to the procedure plus ensure good candidacy. Prpic Eyecare Centre have partnered with Precision Technology Services for manufacturing of custom lenses, and is equipped with advance technology, including a corneal topographer, which increases the likelihood of success for the procedure.
Lens Fitting and Trial Period:
If the optometrist determines that orthokeratology is a good option for you, they will take measurements of your eyes and use this information to design custom orthokeratology lenses. These lenses will be fitted to your eyes, and you will wear them every night while you sleep. You will then undergo a trial period, during which the optometrist will monitor your progress and make any necessary adjustments to ensure that the lenses are providing the desired level of vision correction.
Follow-up Appointments and Adjustments:
After the trial period, you will have follow-up appointments with your optometrist to ensure that the orthokeratology lenses are continuing to provide effective vision correction. These appointments may include additional measurements and adjustments to the lenses to ensure that they are providing the desired level of correction. It is important to attend all scheduled follow-up appointments to ensure the best possible outcomes with orthokeratology. In addition, you should inform your optometrist if you experience any discomfort or changes in vision while wearing the lenses, as this may be an indication that adjustments are necessary.
Risks and Side Effects of Orthokeratology:
Possible Risks and Complications of the Procedure:
Like any medical procedure, orthokeratology carries some risks and potential complications. These can include infection, corneal abrasion, and corneal ulceration. Additionally, some people may experience halos or glare around lights, particularly during the early stages of treatment.
