Corneal Refractive Therapy

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. 


Am I a candidate for corneal refractive therapy?

You may be a candidate for corneal refractive therapy if you:

  • Have a myopia prescription within specific parameters

  • Have a prescription for hyperopia, presbyopia or astigmatism within specific parameters

  • Have stable vision, which means that your prescription hasn’t changed during the last two years

  • Are not a suitable candidate for laser vision correction

  • Have a job that makes it impractical or unsafe to wear glasses or contact lenses

  • Enjoy hobbies that make it impractical or unsafe to wear glasses or contact lenses

  • Have healthy eyes and are generally in good health

Dry Eye Advanced Diagnostic Testing

Dry eye is a common ocular condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, redness, blurred vision, and even damage to the surface of the eyes. Understanding the causes and symptoms of dry eye is crucial provide early detection and effective treatment.
 

The Importance of Dry Eye Advanced Diagnostic Testing

 

Early detection of dry eye is crucial for preventing further progression of the condition and improving patient outcomes. Without proper diagnosis and treatment, dry eye can cause significant discomfort and affect daily activities. Additionally, chronic dry eye can lead to corneal ulcers, infections, and even vision loss. By accurately identifying and addressing dry eye in its early stages, optometrists can provide timely interventions and prevent complications.
 

TearLab

 

One of the advanced diagnostic tools available for dry eye is TearLab. TearLab is a non-invasive test that measures the osmolarity of tears, which is an indicator of tear film stability. This test provides valuable information about the quality and quantity of tears, allowing healthcare professionals to accurately diagnose and monitor dry eye. By analyzing the osmolarity of tears, TearLab helps identify the severity of dry eye and guides treatment decisions. It is a quick and painless procedure that can be performed in a clinical setting.
 

InflammaDry

 

Inflammation plays a significant role in dry eye, and identifying the presence of inflammation is crucial for effective treatment. InflammaDry is a diagnostic tool that detects elevated levels of matrix metalloproteinase 9 (MMP-9), an inflammatory marker, in tears. By measuring MMP-9, InflammaDry helps optometrists differentiate between inflammatory and non-inflammatory dry eye. This information is essential for tailoring treatment plans and determining the most appropriate therapies for each patient.


TearCare: Understanding Dry Eye and Its Causes

Dry eye is a common condition that affects millions of individuals worldwide. It occurs when the eyes do not produce enough tears or the tears evaporate too quickly. This can lead to discomfort, irritation, and even vision problems. TearCare offers a breakthrough treatment option for long-lasting relief from dry eye.
 

What is TearCare?

 

TearCare is a revolutionary treatment option that offers long-lasting relief for dry eye sufferers. This innovative technology utilizes wearable eyelid warming devices to precisely deliver heat to the meibomian glands, effectively unclogging them and promoting healthier oil production. The treatment is performed in-office by a trained eye care professional and typically takes less than 15 minutes.
 

TearCare targets the root cause of the problem - meibomian gland dysfunction. By restoring the proper function of these glands, TearCare helps to stabilize the tear film, improve tear production, and alleviate the symptoms of dry eye. This breakthrough solution offers a safe and effective alternative to medications and artificial tear drops, providing long-lasting relief for those suffering from dry eye.
 

How TearCare Works to Treat Dry Eye

 

TearCare works by gently applying heat to the eyelids, stimulating the meibomian glands and promoting the release of healthy oils. The wearable eyelid warming devices are designed to maintain a consistent temperature, ensuring optimal results. The heat helps to liquefy any hardened oils or debris clogging the glands, allowing them to function properly again. This treatment can also help reduce inflammation and improve overall eyelid hygiene.


Low Level Light Treatment

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.


Cosmetic Services

We all want to look our best and in the last decade, we have seen a significant increase in the number of people seeking cosmetic services in order to enhance their appearance. With our eyes being our most distinguishing feature, we want to make the most of them. Thankfully there is now a range of cosmetic services that can help to rejuvenate our eyes and the area around them to keep them fresh, young and wrinkle-free. 

Let’s take a look at some of the services on offer.
 

Pigment removal

The brown pigment spots that appear on the face are often referred to as age spots and are a result of sun exposure. With age, the repeated exposure to UV rays causes melanin, a compound that is responsible for pigmentation and protecting the skin begins to clump together to form an area of hyperpigmentation. Whilst they aren’t any cause for concern, many people feel that they look unsightly. Luckily, there are a number of different treatments that you can get to remove them including topical creams, laser therapy, and chemical peels.

If you are suffering from darker pigmentation then we strongly recommend that you make an appointment with a qualified dermatologist who will recommend the best course of treatment for you, based on your specific needs.
 


LASIK Procedure

If you are one of the thousands of people considering LASIK laser eye surgery, then you will probably be gathering as much information as possible about the treatment. By this point, you are probably aware of the benefits that LASIK offers, such as a reduced or eliminated need for glasses or contact lenses and greater convenience in your day to day life. However, for many patients, despite the advantages of LASIK, the thought of surgery on their eyes is still a cause of anxiety and fear. One of the best ways to alleviate this concern is to find out more about what the procedure entails.
 

Your consultation

Before you can be approved for any form of laser vision correction, including LASIK, you will need to attend a consultation appointment with your surgeon. During the consultation, he will perform an examination of your eyes and use your medical and ocular history to determine if you are a good candidate for the procedure. He will also speak to you about the expected outcome from your surgery, making you aware that while LASIK will dramatically improve your eyesight, there is no guarantee that you will not need to wear glasses in some situations, such as while driving in the dark. 
 

How LASIK Works

LASIK uses a cool, ultraviolet beam of light to reshape the patient’s cornea. Doing so will more accurately focus the light that enters the eye on to the retina, thus improving the patient’s vision. The way in which the cornea needs to be reshaped will depend on the visual needs of the patient. For example, a patient who is far-sighted will need their cornea reshaping to be steeper to experience better eyesight. Alternatively, a patient who is near-sighted will require their cornea to be flattened in order to improve their vision. LASIK can also smooth an irregular cornea into a more standard shape, meaning that the procedure can also be used to correct astigmatism.
 

The LASIK procedure

The LASIK procedure is very fast and straightforward. Although you will probably be in the surgical suite for around half an hour, the actual process only takes a couple of minutes per eye. The rest of the time will be spent preparing and ensuring that you are comfortable. Anesthetic eye drops are given to patients before their procedure so that the entire process is pain-free. If you are particularly anxious, it may also be possible for you to be slightly sedated – this should be discussed with your doctor at your consultation appointment.

Once you are in position, we will use a femtosecond laser to cut a thin, circular flap into the outer cornea. This can then be pulled back to reveal the underlying corneal tissue, known as the stroma so that it can be reshaped using the laser. The exact path that the laser needs to take, known as the topography, will have been pre-programmed ahead of the procedure and can be followed with complete precision and accuracy.

Once the reshaping is complete, the flap is replaced back over the eye and the surgery is complete. There is no need for sutures or bandages as the cornea will start to heal immediately and without any medical intervention.
 


LASIK Co-Management

LASIK co-management is an integral part of vision correction surgery that often goes unnoticed. It involves a partnership between your primary eye care professional and your LASIK surgeon. This cooperative approach ensures that you're provided with the best possible care before, during, and after your procedure.

 

LASIK co-management is the collaborative effort of your eye care team to ensure your vision correction procedure is safe and successful. It's a team approach where everyone plays a significant role in your eye health journey.

 

The Evaluation Process

 

The evaluation process in LASIK co-management is thorough and meticulous. It begins with a comprehensive eye examination by your primary care optometrist. This examination is meant to ascertain your eye health status and determine if you're an appropriate candidate for the LASIK procedure.

 

The evaluation process underscores the collaborative nature of LASIK co-management. Every step is carefully coordinated to ensure your eye health is prioritized and that you're receiving the best possible care.

 

The Importance of Consultation in LASIK Co-management

 

Consultation is a crucial aspect of LASIK co-management. It allows for patient education, addressing concerns and questions, and establishing a clear understanding of the expected outcomes.

 

During the consultation phase, your optometrist will explain the results of your eye examination and how it relates to your suitability for LASIK surgery. They will also discuss the risks and benefits of the procedure, giving you a balanced perspective to make an informed decision.

 

The consultation with your LASIK surgeon will delve into the specifics of the operation, including the technology used, the surgical process, and the anticipated recovery timeline. Having the opportunity to consult with both your optometrist and your surgeon ensures that all your concerns are addressed, allowing you to proceed with confidence.

 

The Role of Communication

 

Effective communication is the backbone of successful LASIK co-management. It facilitates a seamless transition from your optometrist to your surgeon, creating a cohesive care plan that's centered around your specific needs.

 

This communication is not just between healthcare providers but also involves the patient. Regular updates on your progress, detailed explanations about each stage of the process, and addressing any concerns or questions you may have are all essential parts of the communication process.

 


Am I a candidate for LASIK?

If you already rely on wearing glasses or contact lenses to be able to see clearly, you may be frustrated with the effect that they have on your life. Regular vision tests, finding glasses to suit your face shape, having to remember to take eyeglasses with you wherever you go, prescription sunglasses, fiddly contact lenses… the list of inconveniences associated with conventional ocular solutions is extensive. 

LASIK is a modern, minimally-invasive procedure that can substantially reduce or eliminate your need to use eyeglasses or contact lenses, allowing you to enjoy life without limitations or inconvenience. The popularity and success of LASIK laser eye surgery have helped to make it the number one elective surgery across the globe. 
 

Candidacy for LASIK

LASIK has an extremely high success rate. According to the American Society of Cataract and Refractive Surgery, 96% of patients achieve 20/20 vision or better. However, it’s high success rate doesn’t make LASIK automatically the right solution for everyone.

Candidacy for LASIK is assessed by our doctors on a case by case basis so that you be certain that whatever treatment is recommended for you, it will give you the very best opportunity to improve your vision. During your consultation, our doctors will perform a thorough examination of your eyes and vision, ask you about your general health and talk you through both the procedure and aftercare.

The general guidelines for LASIK candidacy state that patients must:

  • be at least 18 years of age

  • have had stable vision with no prescription changes for a minimum of 12 months

  • have a current prescription for eyeglasses or contact lenses that falls between specified parameters (Our doctors will be aware of what these parameters are)

  • have no significant medical or eye-related problems such as glaucoma, macular degeneration or diabetic retinopathy

  • have no history of corneal disease

  • not be pregnant or nursing at the time of the procedure


iDesign Custom Lasik

If you thought that just laser eye surgery was impressive, then be prepared to be astounded by the arrival of iDesign custom Lasik. iDesign is the most advanced wavefront-guided laser treatment available. The system creates a uniquely accurate measurement of the entire optical system that can be relied upon completely without any guesswork. This is then used to create a highly detailed topography or map of your eye, making it easier for your surgeon to pinpoint the areas that need addressing with pinpoint precision. 
 

How accurate is iDesign?

iDesign is extremely accurate due to its diagnostic equipment that is able to determine 1,257 different micro eye prescriptions. Each one of these will measure the eye prescription to 0.01 of a dioptre strength – 25 times more than what a regular prescription for glasses or contact lens prescription is measured to. 
 

Who is iDesign suitable for?

While iDesign Custom Lasik can benefit almost any patient with refractive problems, it is particularly beneficial for people who have unusual corneas or have had eye surgery in the past. 
 

Is it painful?

Laser eye surgery is generally considered a pain-free procedure by the majority of patients. Anesthetic eye-drops are used to numb the outer area of the eye during the course of the surgery. Once these have worn off, some patients do experience some mild discomfort during the days following the procedure, but over the counter pain relief is usually sufficient to relieve this.
 


Limbal Relaxing Incisions

Astigmatism is a relatively common eye disorder that causes the vision to be blurred or distorted. It occurs when the lens part of the eye, known as the cornea, isn’t perfectly curved and instead resembles a football rather than a soccer ball. This means that the light entering the eye comes through at a distorted angle, making the object appear blurry and out of focus. There are several ways in which it is possible to treat astigmatism, including laser eye surgery and corrective lenses. However, another possibility is a solution referred to as limbal relaxing incisions.
 

What are limbal relaxing incisions?

Limbal relaxing incisions are microscopic cuts to an area in the eye known as the limbus. This helps to relax the curve in the cornea and improve its ability to focus light correctly. It can significantly improve your astigmatism and the overall quality of your vision.
 

Am I a good candidate for limbal relaxing incisions?

If you have astigmatism, are over 18, in good general health and have no major eye conditions, then chances are you are a good candidate for limbal relaxing incisions. Make an appointment with your eye doctor to discuss your candidacy further.
