Maculogix are the manufacturers of the AdaptDX Pro – a fully automated dark adaptometer. This innovative piece of technology measures how quickly eyes can adjust from being in bright light to darkness and vice versa, and is an invaluable tool for the detection and diagnosis of macular degeneration.

What is macular degeneration?

Macular degeneration, also known as age-related macular degeneration or AMD, is a common progressive eye disease most often seen in people over the age of 60. It is a leading cause of permanent vision loss and any sight that has been compromised will not be able to be restored. AMD occurs when the cells in a part of the retina called the macula degenerate, usually with age, but this degeneration is also likely to happen more quickly in patients with poor lifestyle choices, such as those who are overweight, who smoke and who have high blood pressure and other cardiovascular diseases.

There are a range of symptoms associated with macular degeneration. These include:

- Reduction in central vision

- Distortion of straight lines in your central vision

- Trouble recognizing faces

- Difficulty reading, driving or watching tv

- Problems seeing in dark environments

- Generally blurred vision

One symptom is an increase in the amount of time it takes for the eyes of someone with the disease to adjust when walking from a bright environment into a dark one. This is known as dark adaptation and is something that is taken into account when diagnosing AMD.

What is the Maculogix AdaptDX Pro?

AdaptDX Pro allows your eye doctor to perform darkness adjustment testing in a standard room rather than a darkroom. This is because the cups that are placed over the eyes form a perfectly light-proof seal, shutting out all traces of light and showing how well your eyes adjust to pitch black darkness.

What to expect from your appointment?

Once the AdaptDX Pro headset is placed over your head and adjusted to fit you, and the eyecups have been altered to block out all light, you’ll be asked to look into the device and wait. Every time you see light, you’ll be asked to push down on a button that you will be holding in your hand. The technology within the headset attached to the cups tracks the way that your pupils react to light changes in real time, then provide this information as data, which your eye doctor can then use to decide if you should receive a diagnosis of macular degeneration. The test is simple, painless and takes just a few minutes.

If you are concerned that you may be experiencing some of the symptoms associated with macular degeneration and would like more information about the condition, or to talk to someone about Maculogix AdaptDx Pro testing, please get in touch with our office today.

$Corneal Refractive Therapy$

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

EnChroma Lens Technology

If you find it difficult to tell colors apart, you may be color blind. Color blindness, or color deficiency, is estimated to affect around 8% of men and about 1% of women, but for those affected, it can significantly impact the quality of their day-to-day life. Contrary to popular belief, being color blind doesn’t mean that you can’t see any color at all. Instead, patients simply struggle to differentiate between certain colors. The vast majority of people who are color blind find it impossible to tell the difference between varying shades of red and green. You may hear this referred to as red-green color deficiency. However, this doesn’t only mean that they mix up red and green. They can also mix up colors that have some green or red light as part of their whole colors, for example purple and blue. This is because they are unable to see the red light that forms part of the color purple.

As you can probably imagine, this type of visual impairment can be a problem for things like traffic lights, taking medications and even looking at signs and directions. For example, someone who is color blind may find that the green on a traffic light may appear white or even blue.

EnChroma lens technology is specifically designed to counteract red-green color deficiency and enable patients to better identify the difference in these colors or shades. They do this by selectively filtering out the red and green wavelengths of light at the exact point where the color sensitivities overlap before hitting the retina, creating far greater contrast between the colors so that the patient can distinguish between them successfully. Most cases of color blindness respond well to EnChroma’s innovative spectral lens technology, giving patients the ability to experience life in bright, vibrant technicolor.

EnChroma lenses are made from leading edge, Trivex material, and this helps to give them the best possible quality and clarity of vision. These lenses are also extremely light, strong and offer patients 100% protection against UV light, helping to keep your eyes healthy as well as improving your vision.

If you or someone you know is color blind or color deficient and could benefit from EnChroma lenses, contact us today to learn more about how they can help!

Optikam

Eye care professionals use Optikam’s technology to capture more than 3 million eyewear measurements every year. The OptikamPad iPad app is a total dispensing solution that enables eye care professionals to successfully assist patients at all stages of the eyewear dispensing process, providing them with a unique and custom patient experience.

Optikam Posture Devise (OPD)

You may be surprised to learn that wearing glasses can and likely will affect your posture. Glasses lenses are most accurate when you look directly through their center. This means if your glasses are sitting too low or have slipped down your nose, you may find that you are subconsciously tilting your head back and this can affect your overall posture.

Optikam’s OPD measurement device is a cutting-edge tool that obtains eyewear measurements that take into account how the frame will be worn by patients, enabling the fit to be customized to their individual parameters. The ten measurements taken into account when determining each patient’s position of wear include:

- Monocular pupillary distance

- Multifocal seg heights

- Pantoscopic tilt

- Rear vertex distance

- Wrap (face form tilt)

- Near pupillary distance

This results in frames that not only look fantastic, but that also fit perfectly, remaining both comfortable and stable on the face without you needing to adopt an unnatural posture. The measurements obtained by the Optikam OPD measurement tool are immediately visible on your eye doctor’s tablet so that they can recommend which alterations to the frames are needed to ensure that the frames fit with precision and gives you the best visual experience.

Benefits of OptikamPad and Optikam OPD

Traditionally, the process of a comprehensive eye exam, choosing frames and fitting glasses requires fairly close contact with your eye doctor or other eye care professionals. However, with social distancing being a new process variable, many patients are looking for more virtual options. Fortunately, OptikamPad makes it possible for optical stores to dispense eyeglasses with minimal human contact. This is because the OptikamPad can take measurements from a further distance or even through plexiglass screens. It can even be placed on a stand and the app operated using a Bluetooth mouse, putting even greater distance between your eye care professional and you.

If you would like to find out more about Optikam OPD and OptikamPad, our knowledgeable team would be delighted to help. Please contact us with any questions or to schedule an appointment.

Neurolens

Neurolens are the first and only prescription lenses that include an element of contoured prism in their design. This prism is designed to bring the patient’s eyes into more equal alignment, and this should help to provide relief from the symptoms that are associated with several eye misalignment conditions, including digital eye strain and binocular vision dysfunction.

What is digital eye strain?

Digital eye strain is the name given to describe a group of symptoms that can occur when someone spends long periods of time using digital devices. Since using digital devices requires the eyes to work harder than normal and we don’t always position our devices the perfect distance away, it can lead to issues such as eye pain, dry and irritated eyes, eye fatigue, light sensitivity and blurred vision. Unsurprisingly, the number of people who are experiencing digital eye strain has grown significantly over the last few years and is expected to continue to do so.

What is binocular vision dysfunction?

Binocular vision dysfunction, also known as BVD for short, is another eye condition but is one that is very misunderstood. Binocular vision dysfunction occurs when the eyes aren’t perfectly aligned, causing your brain and eyes to work harder than normal in order to create a clear visual image and remain focused. This places pressure on the trigeminal nerve, which is the nerve that is responsible for the majority of the sensations that we experience in our head and back. BVD can often manifest as other things owing to the huge range of symptoms that are associated with the condition. These can include, but aren’t limited to:

- Blurred vision

- Headaches/migraines

- Double vision

- Motion sickness

- Vertigo

- Dizziness

- Anxiety

Many people don’t think to visit an eye doctor when they are experiencing these symptoms, but all can occur simply because the eyes are out of alignment.

What are Neurolens lenses and how do they help?

As well as containing your usual prescription, Neurolens lenses also contain a specific amount of contoured micro-prism. This micro-prism alters the position of images so that they are aligned in the same plane. This then reduces the pressure on the muscles around the eyes as well as bringing the eyes into alignment, easing the symptoms that the patient has been experiencing.

The amount of prism in Neurolens lenses is decided using the Neurolens eye-tracking device. This non-invasively measures the misalignment that the patient is experiencing, and this is used to form the basis for the patient’s Neurolens prescription. After this, it’s fairly normal for the amount of prism to need to be adjusted by infinitesimal amounts to achieve the optimal relief from your symptoms. Most patients who choose Neurolens treatment see a 50% improvement in their vision as soon as they start to have micro-prism incorporated into their prescription lenses. However, with careful adjustments, many patients see as much as an 80% reduction in the effects of digital eye strain and binocular vision dysfunction.

Tonometer

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. These 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.

What to expect from tonometry testing

There are various methods of tonometry testing, but many eye doctors use either Goldmann tonometry, which is the conventional technique to measure eye pressure, or electronic tonometry.

Goldmann tonometry testing is carried out using the Goldmann applanation tonometer, which is attached to a slit lamp microscope. This requires anesthetic eye drops to be used which numb your eyes, before a small probe is pressed gently against the eye, indenting the cornea. The pressure that the cornea pushes back onto the tonometer is what is measured to give your IOP reading. Electronic tonometry is where a handheld, mobile device is gently and quickly applied to the cornea to check the pressure, providing an accurate reading. Some eye doctors also offer non-contact tonometry which is where a puff of air is used to flatten the cornea, although this is reported to be less accurate than the Goldmann technique.

Speciality Contact Lenses

Every patient is different and so are their eyes. This means that there need to be different types of contact lenses to suit each individual. Some patients have corneal abnormalities which mean that conventional lenses won’t sit comfortably on the surface of their eyes, while others suffer from eye conditions that mean normal contact lenses won’t be comfortable or could irritate their eyes.

As you may have guessed from the name, specialty contact lenses are unconventional contacts that are designed for patients that regular contacts might not be suitable. Here are some of the main types of speciality contact lenses and who they are recommended for.

Who might be a good patient for specialty contact lenses?

Some of the patients that might benefit from specialty contact lenses include those who:

have been diagnosed with dry eye syndrome
have corneal scarring
have been diagnosed with keratoconus, a condition characterized by the bulging of the cornea
suffer from strabismus, a condition where the patient has an eye that turns in or out relative to the other
have suffered an injury to the eye
suffer from a peripheral corneal thinning disorder
are intolerant to other types of lenses

Your eye doctor or contact lens provider will be able to tell you if you need specialty contact lenses and if so, which lenses would be best based on your individual requirements.

Rigid Gas-Permeable Lenses

Also known as RGP lenses, these are made from a special material that allows oxygen to pass through them and reach the surface of the eyes. This helps to keep the eyes hydrated and comfortable, making these lenses easier to wear, especially for patients who suffer from dry eyes. Dry eyes aren’t just a symptom, but a very real condition, characterized by dry, stiff, and uncomfortable eyes, blurred vision, and eye fatigue. RGP lenses are more rigid than soft lenses, and this helps to keep them stable and secure on the eyes so that patients can enjoy sharper vision. They also help the cornea to maintain its shape, which helps to minimize the effects of some corneal abnormalities.

Scleral Contact Lenses

Scleral contact lenses are very different to standard contact lenses. This is because scleral lenses are much larger in diameter, with three different sizes available depending on your specific needs. This size difference means that the edges of the contact lens fall on a white part of the eye, called the sclera rather than the cornea. Scleral lenses are also different in that they vault over the surface of the cornea rather than touching it, leaving a space between the front surface of the eye and the back of the contact lens. This makes scleral lenses a good choice for patients with dry eyes and corneal abnormalities. Space can trap tear film which keeps the eyes hydrated, while space also accommodates many corneal abnormalities, such as the bulge associated with keratoconus.

Limbal Fit Contact Lenses

Limbal contact lenses are another type of specialty lens that falls between rigid gas-permeable lenses and scleral varieties in terms of their size. Their larger overall diameter helps to increase their stability on the surface of your eyes. They also offer minimal interference with the eyelids, which helps to ensure comfort and clarity of your vision.

Hybrid Contact Lenses

Hybrid contact lenses are a combination of both soft and gas-permeable contact lenses, giving patients the opportunity to enjoy the best parts of both designs. The middle part of hybrid lenses is made from gas-permeable material that lets oxygen pass through to the eyes. However, the gas-permeable part of the lens is more rigid, and this firmer center gives the lens greater stability and the patient enhanced clarity. The RGP portion of the lens also helps to trap a tear film between the cornea and the lens so that the eye remains hydrated. Meanwhile, the outer edge of hybrid lenses is a soft lens skirt. This means that patients don’t have to deal with the hard edges associated with RGP lenses that may be uncomfortable. Instead, the comfort levels that patients experience are more like wearing fully soft lenses.

Optical Coherence Tomography

Optical Coherence Tomography is a non-invasive imaging test that may be performed as a standard part of your regular, comprehensive exams, or you may be able to request this test as an addition to your usual exam.

Optical Coherence Tomography uses light waves to take cross-section images of your retina, which is the area of light-sensitive cells at the back of your eye that is responsible for receiving light and transmitting it into messages that are sent up to the brain. The technology behind OCT enables your eye doctor to see each of the different layers that make up the retina. By being able to see these and measure them, they can obtain a much clearer picture of the overall health and condition of your eyes.

Why are Optical Coherence Tomography scans important?

When you choose to have an OCT scan at fairly regular intervals, such as during your normal comprehensive eye exams, your eye doctor can compare newer results to previous ones. This helps them to build up a picture of the health of your eyes, and spot any changes which may be concerning, early, before they cause symptoms or have a permanent effect on your vision.

Anyone can have an OCT scan, but they are particularly recommended for patients over the age of 25 who are concerned about the health of their eyes, or who are at risk of or already have diabetes, glaucoma or a family history of eye disease. This is because they can be used to spot the early signs of a range of eye diseases, including glaucoma, diabetic retinopathy, macular degeneration, disorders of the optic nerve and more – even before you realize that you are affected.

What happens during an Optical Coherence Tomography scan?

An OCT scan is a quick, painless experience. To prepare you, your eye doctor may require you to have eyedrops that will dilate your pupils and make it easier to see your retina. This means that the scanner will get clearer, more concise images. You’ll be asked to sit in front of the OCT machine where you will rest your head against a support to help you sit perfectly still. As you stare ahead, the equipment will perform the scan of your eyes. There is no contact with your eyes whatsoever, you will just need to sit still, with your eyes open as much as possible during the process, which usually takes less than 10 minutes. The images will be sent digitally to your eye doctor for them to assess immediately and stored digitally on your personal record.

There’s no downtime after an OCT scan, but if you have had your eyes dilated you may find that you are particularly sensitive to light for a few hours afterwards. This occurs because the pupils remain wider and therefore able to let more light in that usual.

Lipiflow

Dry eyes are one of the most common conditions that can affect our eyes and is estimated to affect millions of Americans. As you’ve probably guessed, dry eyes occur when tears fail to provide enough natural lubrication for the eyes to be comfortable and healthy. Exactly what causes dry eyes can vary significantly, from side effects from medications to prolonged computer use. What is clear is that while the condition isn’t sight-threatening, it can make day to day life much harder than it needs to be. Fortunately, there are treatments that can help, and arguably one of the most effective is Lipiflow.

What is Lipiflow?

Lipiflow is a new technological solution that addresses the underlying cause of your dry eyes, rather than simply treating the symptoms. It is most effective at helping patients whose dry eyes are caused by meibomian gland dysfunction – a condition characterized by problems with the way that the meibomian glands produce the oil that forms an essential part of our tear film. The meibomian glands can become less productive, or in some cases, even blocked by hardened oil deposits. This prevents the oil from reaching your tear film, making it less effective. Lipiflow targets the meibomian glands, warming them to break down oily blockages and massaging your eyes to make sure that the oil, and then the tear film, is evenly dispersed. This helps to combat the symptoms associated with dry eyes, which can include:

- Eye fatigue

- Dry, scratchy and uncomfortable eyes

- Blurred vision

- Sensitivity to light

- Difficulty wearing contact lenses

Your eye doctor will be able to advise you if Lipiflow has the potential to be a suitable solution for your dry eyes.

What to expect from Lipiflow treatment?

Lipiflow treatment is a simple, painless process that is performed in the comfort of your eye doctor’s office. There is no need for anesthetic. Once you are settled in your chair, your eye doctor will open the sterile, single-use applicators which are placed over your eyes. These are connected to a machine that causes the inner eyelids to heat to approximately 42.5°C to, while simultaneously placing gentle pressure on the outer eyelid surfaces. Lipiflow takes around 12 minutes per eye, during which time you can relax. You can even listen to music if you’d like to. There is no downtime, and patients can return to their usual activities right away. It takes around 3 days for patients to begin to see an improvement in their dry eye symptoms, although they may require further treatment in the future to maintain them. Optimal results are usually achieved around 6 to 8 weeks following your Lipiflow treatment.
