Corneal refractive therapy, also known as CRT, is a simple, painless treatment for refractive eye errors like myopia and has two core benefits. First, it can be used to help patients see clearly during the day without using glasses or contact lenses, giving them the freedom and flexibility that they need to live life to the fullest. Second, CRT has been shown to help slow the progression of myopia, keeping prescriptions under control and potentially reducing the likelihood of patients developing serious eye health problems associated with high myopia in the future. 

Here’s everything that you need to know about corneal refractive therapy and what it means for you. 

Understanding refractive eye problems

Refractive eye problems like nearsightedness, farsightedness and astigmatism are extremely common, with nearsightedness – also known as myopia – being the most common of all. Patients with myopia can see nearby objects clearly, but those further away become progressively more blurred. Refractive eye errors occur when the shape of the clear dome covering the front part of the eye, called the cornea, impair the light-bending and focusing process in your eyes. This leads to the light ending up in the wrong place inside the eye, and the message that is sent to our brain from our eyes is muddled, causing blurred vision. 

What is corneal refractive therapy?

Corneal refractive therapy was initially developed as a treatment to correct and slow the progression of nearsightedness. However, it has also been found to be effective at controlling other refractive errors, including farsightedness, astigmatism and an age-related refractive condition called presbyopia.

CRT is a non-invasive, painless and straightforward method of correcting patient vision so that they don’t need to wear contacts or glasses, and they don’t need laser vision correction surgery to see clearly. CRT uses special contact lenses that are worn overnight and apply light pressure to the cornea in order to reshape it so that light is refracted correctly, and the image sent from the eyes to the brain is clear. The cornea is able to retain this new shape even after the contact lenses are removed the next morning, meaning that you can continue to see clearly for several hours. The more consistently you wear your CRT lenses overnight, the longer your eyes will learn to retain their new shape and eventually, patients can enjoy up to 48 hours of clear vision without using prescription lenses. However, the effects aren’t permanent so if you stop wearing the lenses, your vision will gradually return back to normal over the course of a few days. 

Slowing the progression of myopia with corneal refractive therapy

Another key benefit of CRT is that it can actually help to slow the progression of myopia. Most people who are nearsighted find that their eyesight gets progressively worse as they get older. This deterioration may not be rapid, but it can end in patients requiring high prescriptions. Studies have found that patients who have high myopia are more likely to develop serious eye problems in the future, including glaucoma, macular degeneration, cataracts and a detached retina. Regular use of your corneal refractive therapy lenses could help keep your prescription stable and lower your risk of developing these problems. 

Dry eye is a common condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. There are several factors that can contribute to dry eye, including environmental factors, hormonal changes, and certain medications. Additionally, conditions such as meibomian gland dysfunction and blepharitis can also lead to dry eye.

The Role of Meibomian Gland Dysfunction and Blepharitis in Dry Eye

Meibomian gland dysfunction occurs when the meibomian glands, which are responsible for producing the oily layer of tears, become blocked or do not function properly. This can result in the tears evaporating too quickly and not providing enough lubrication for the eyes. Blepharitis is an inflammation of the eyelids that can cause redness, itching, and a gritty sensation in the eyes. Both meibomian gland dysfunction and blepharitis can contribute to dry eye by disrupting the natural tear film.

Recognizing the Symptoms of Dry Eye

Dry eye can cause a variety of symptoms, which can vary in severity from person to person. Some common symptoms of dry eye include:

• Dryness: The most common symptom of dry eye is a feeling of dryness or grittiness in the eyes. This can make it uncomfortable to wear contact lenses or spend long periods of time looking at a screen.

• Redness: Dry eye can cause the blood vessels in the eyes to become more prominent, leading to redness and irritation.

• Itching: Some people with dry eye may experience itching or a burning sensation in their eyes.

• Excessive tearing: Dry eye can also cause excessive tearing. This is the body's response to the irritation caused by the lack of lubrication in the eyes.

If you are experiencing any of these symptoms, it is important to consult with an optometrist for a proper diagnosis and treatment plan.

A tonometer refers to the equipment that is used in tonometry – a test that measures the pressure inside your eyes, also known as intraocular pressure or IOP for short. Tonometry is rarely performed at your average comprehensive eye exam unless you are at high risk of or have been already diagnosed with glaucoma. Fortunately, tonometry can be used to detect changes in eye pressure before they cause any symptoms, enabling prompt action to be taken before your vision is affected.

About Glaucoma

Glaucoma is a common eye condition that occurs when the optic nerve, which connects the eye to the brain, becomes damaged. It’s normally caused by fluid building up in the front part of the eye, which causes the pressure inside the eyes to build. As the pressure increases, the optic nerve becomes increasingly damaged, and this prevents messages from being transmitted between your eyes and brain effectively. As a result, the patient’s vision becomes compromised. Without treatment, the level of vision loss will continue to increase. Unfortunately, any vision that has been lost as a result of glaucoma cannot be restored.
 

Most of the time, glaucoma develops very slowly which means that many people don’t realize that they are affected until some damage to their vision has already occurred. However, occasionally glaucoma can develop quickly, and symptoms do occur.

Glaucoma symptoms can include:

• Red eyes

• Intense headaches

• Tenderness around the eyes

• Eye pain

• Seeing rings/halos around lights

• Blurred vision

• Nausea and vomiting

If you notice any of these symptoms, it’s important that you make an appointment with your eye doctor right away so that you can be assessed. You are likely to have a tonometry test as part of this assessment.

As technology continues to advance, so does the field of the optometric industry. The development of innovative tools and techniques has allowed for more accurate and comprehensive examinations. One such technology is Optos, a revolutionary system that utilizes ultra-widefield retinal imaging technology to provide optometrists with a detailed view of the entire retina.

How Does Optos Work?

Optos technology is based on the principle of ultra-widefield retinal imaging, which allows for a wider and more detailed view of the retina compared to traditional imaging techniques. The Optos system consists of a specialized camera that captures high-resolution images of the retina using scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT) technologies. SLO provides a wide-field view of the retina, while OCT allows for cross-sectional imaging, providing valuable insights into the various layers of the retina.

The Optos camera is designed to capture images through a process called optomap, which captures up to 200 degrees of the retina in a single image. This wide-field view provides optometrists with a comprehensive picture of the retina, enabling them to detect abnormalities that may not be visible with traditional imaging techniques. The optomap image can be instantly viewed and analyzed by your eye doctor, allowing for a more efficient and accurate diagnosis.

Common Eye Conditions Detected by Optos

Optos technology has the capability to detect a wide range of eye conditions, including but not limited to, diabetic retinopathy, macular degeneration, glaucoma, and retinal tears or detachments. Diabetic retinopathy is a condition that affects individuals with diabetes, causing damage to the blood vessels in the retina. Optos can capture detailed images of the retina, enabling optometrists to detect any signs of diabetic retinopathy and initiate appropriate treatment.

Macular degeneration is another common eye condition that can be detected using Optos. This condition affects the macula, the central part of the retina responsible for sharp, central vision. Optos allows for a comprehensive view of the macula, identifying any changes or abnormalities that may indicate the presence of macular degeneration.

Glaucoma, a condition characterized by damage to the optic nerve, can also be detected using Optos. The wide-field view provided by Optos allows for a thorough examination of the optic nerve and the surrounding structures, facilitating early detection and intervention.

Finally, Optos technology is particularly effective in detecting retinal tears or detachments. These conditions can lead to sudden vision loss and require immediate medical attention. Optos allows for a comprehensive view of the retina, identifying any signs of retinal tears or detachments and initiate prompt treatment.

Dry eye is a common condition that affects millions of people worldwide. It occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, irritation, and even vision problems. If you are suffering from the discomfort of dry eye, MiBo Thermoflo can offer you a revolutionary solution.

Understanding the Causes of Dry Eye

Dry eye is a condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. There are several factors that can contribute to this condition, including environmental factors, certain medications, and aging. Environmental factors such as dry or windy climates, air conditioning, and excessive screen time can all worsen dry eye symptoms. Additionally, certain medications like antihistamines, decongestants, and diuretics can decrease tear production. Aging is also a common cause of dry eye, as tear production naturally decreases as we get older.

Meibomian gland dysfunction (MGD) and blepharitis are two common conditions that can contribute to the development of dry eye. MGD occurs when the meibomian glands, which are responsible for producing the oily layer of tears, become blocked or dysfunctional. This can lead to an inadequate amount of oil in the tears, causing them to evaporate too quickly. Blepharitis is an inflammation of the eyelids that can disrupt the normal functioning of the meibomian glands.

Millions of people suffer from eye and vision-related problems. For some, the solution is as simple as wearing prescription eyeglasses or contact lenses. However, others face challenges that aren’t as easy to rectify. That’s where Lumenis comes into play.

Managing Symptoms

According to recent statistics, roughly 22% of the U.S. population suffers from dry eye disease along with MGD. That combination leads to an array of uncomfortable symptoms.

Dry eye occurs when a person’s eyes don’t produce adequate tears to keep them lubricated or when tears don’t work the way they should. MGD is a condition that affects the small glands in the eyelid responsible for making the oil layer for tears.

Having to deal with one of these problems is bad enough. However, living with both can prove debilitating for some people. Thanks to OptiLight, people with the two conditions get much-needed relief. Here are the ways this advanced technology helps:

• Reduces inflammatory mediators, which, thereby, prevents inflammation

• Improves tear breakup time that, in response, decreases osmolarity

• Alleviates abnormal blood vessels that commonly cause inflammation

• Restores meibomian glands so they function properly

• Decreases demodex mites that cause infection and the accumulation of bacteria on the eyelids

In the realm of eye care, surgical co-management has emerged as a collaborative approach that aims to provide patients with comprehensive and seamless treatment. This concept involves the joint efforts of optometrists and ophthalmologists, each bringing their unique expertise to the table. By working together, these eye care professionals strive to enhance patient outcomes and deliver exceptional care.

The Role of Optometrist and Ophthalmologist in Surgical Co-Management

Surgical co-management is built upon the unique skill sets and areas of expertise of optometrists and ophthalmologists. By understanding their respective roles, you can appreciate the synergy that this collaborative approach fosters.

Optometrists are primary eye care professionals who specialize in the examination, diagnosis, and non-surgical treatment of vision disorders. Their responsibilities in surgical co-management include:

• Performing comprehensive eye examinations and evaluations

• Monitoring and managing pre-existing eye conditions

• Providing pre-operative and post-operative care

• Educating patients on surgical procedures and aftercare

• Collaborating with ophthalmologists to ensure continuity of care

Ophthalmologists are medical doctors who specialize in the diagnosis, treatment, and surgical management of eye diseases and disorders. Their role in surgical co-management encompasses:

• Evaluating patients' candidacy for surgical interventions

• Performing complex surgical procedures

• Providing specialized medical and surgical care

• Collaborating with optometrists to ensure seamless patient care

• Monitoring and managing post-operative complications

• By combining the expertise of optometrists and ophthalmologists, surgical co-management ensures that patients receive comprehensive and coordinated care throughout their treatment journey.

How Surgical Co-Management Works

Surgical co-management is a well-orchestrated process that involves several key steps. Understanding how it works can help you navigate this collaborative approach with confidence.

• Initial Evaluation: The process typically begins with an optometrist conducting a comprehensive eye examination. During this evaluation, the optometrist assesses the patient's visual needs, identifies any potential issues, and determines if a surgical intervention is necessary.

• Referral and Consultation: If surgery is recommended, the optometrist refers the patient to an ophthalmologist for further evaluation and consultation. This step ensures that the patient receives specialized medical advice and a thorough assessment of their suitability for the proposed surgical procedure.

• Pre-operative Care: The optometrist plays a crucial role in providing pre-operative care, which may include managing any existing eye conditions, ensuring the patient understands the surgical process, and addressing any concerns or questions they may have.

• Surgical Procedure: The ophthalmologist performs the necessary surgical intervention, leveraging their specialized training and expertise in surgical techniques.

• Post-operative Care: After the surgery, the patient's care transitions back to the optometrist, who closely monitors the recovery process and provides post-operative care and management. This may involve follow-up appointments, monitoring for any complications, and ensuring the patient adheres to the prescribed treatment plan.

• Ongoing Collaboration: Throughout the entire process, the optometrist and ophthalmologist maintain open communication and collaborate closely. This ensures that the patient's care is seamless, and any concerns or issues are promptly addressed by the appropriate healthcare professional.

In the ever-evolving world of vision correction, multifocal contact lenses have emerged as a game-changer for individuals seeking a seamless solution to address their presbyopia. As you navigate through life's various stages, your eyes may undergo changes that can impact your ability to focus clearly on objects at different distances. Multifocal contact lenses offer a convenient and effective way to combat this challenge, providing you with a versatile and comfortable option for correcting your vision.

What Are Multifocal Contact Lenses?

Multifocal contact lenses are specialized lenses designed to correct presbyopia, a condition that typically occurs as you age, making it difficult to focus on near objects. Unlike traditional single-vision lenses that correct either near or distance vision, multifocal contact lenses incorporate multiple prescriptions into a single lens. This innovative design allows you to enjoy clear vision at various distances, eliminating the need for separate reading glasses or bifocals.
 

How Do Multifocal Contact Lenses Work?

Multifocal contact lenses employ advanced optical technologies to provide seamless vision correction. These lenses feature distinct zones or concentric rings that correspond to different prescriptions for near, intermediate, and distance vision. As your eyes move and focus on objects at varying distances, the appropriate zone of the lens comes into play, ensuring a clear and comfortable visual experience.

There are two main types of multifocal contact lens designs:

• Simultaneous Vision Design: In this design, the lens incorporates multiple prescriptions simultaneously, allowing your eyes to utilize the appropriate zone based on the viewing distance. This design can take some time to adjust to, as your brain learns to interpret the different visual inputs.

• Alternating Vision Design: Also known as "segmented" or "translating" lenses, these lenses have distinct zones for near and distance vision. As you move your eyes or shift your gaze, the appropriate zone is positioned in front of your pupil, providing the necessary correction.

Eye Conditions That Multifocal Contact Lenses Can Treat

Multifocal contact lenses are primarily designed to address the following vision-related conditions:

• Presbyopia: As you age, the natural lenses in your eyes lose flexibility, making it challenging to focus on nearby objects. Multifocal contact lenses can correct this age-related farsightedness, allowing you to see clearly at all distances.

• Myopia (Nearsightedness): If you struggle to see distant objects clearly, multifocal contact lenses can incorporate a prescription to correct myopia, while also providing near and intermediate vision correction.

• Hyperopia (Farsightedness): For individuals with farsightedness, multifocal contact lenses can offer a solution by incorporating a prescription to improve distance vision, along with near and intermediate vision correction.

• Astigmatism: Some multifocal contact lenses are designed to correct astigmatism, a condition caused by an irregularly shaped cornea or lens, resulting in blurred or distorted vision.

Presbyopia is a natural and inevitable part of aging that affects the eyes' ability to focus on close objects. Unlike other vision conditions, presbyopia isn’t caused by the shape of the eye or structural abnormalities but is instead a result of the eye’s lens losing its flexibility over time.

What is Presbyopia?

Presbyopia is a refractive error, meaning it affects how the eyes bend (or refract) light to focus it on the retina. Unlike nearsightedness (myopia) or farsightedness (hyperopia), which are caused by the shape of the eyeball or cornea, presbyopia is due to the aging of the eye's lens. Over time, the lens becomes less flexible, making it difficult to focus on nearby objects. Presbyopia isn’t a disease or an abnormality—it’s simply a natural consequence of the aging process.

What Causes Presbyopia?

The lens inside the eye changes shape to focus light on the retina, allowing us to see clearly at varying distances. When viewing nearby objects, the lens thickens and curves to increase its refractive power.

As we age, however:

• Lens Stiffening: The lens loses elasticity, making it harder to bend and adjust for near vision.

• Weakened Ciliary Muscles: The muscles that help change the shape of the lens may lose their strength over time, further reducing the eye’s ability to focus on close objects.

• Structural Changes: The lens also grows thicker and less transparent with age, which contributes to reduced focusing ability.

These changes are gradual, typically starting in a person’s 30s and becoming noticeable by their early to mid-40s.
