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.

Clear Lens Extraction (CLE) is a surgical procedure that involves the removal of the natural lens of the eye and replacing it with an artificial lens implant, also known as an intraocular lens (IOL). CLE is primarily performed to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism.

Understanding CLE and How It Works

Clear Lens Extraction is similar to cataract surgery, where the natural lens is removed and replaced with an IOL. However, in CLE, the lens is clear and not clouded as in the case of cataracts. The procedure begins with the administration of local anesthesia to numb the eye and ensure a painless experience for the patient.
 

Once the eye is numb, a small incision is made on the cornea, which is the clear front surface of the eye. Through this incision, your eye surgeon accesses the lens and carefully removes it. The artificial IOL is then inserted into the empty lens capsule. The IOL is specifically chosen to correct the patient's refractive error, providing them with improved vision.
 

After the IOL is implanted, the incision is closed with tiny sutures or self-sealing techniques. Following the surgery, patients are usually prescribed antibiotic and anti-inflammatory eye drops to prevent infection and reduce inflammation.

Factors to Consider Before Undergoing Clear Lens Extraction

Before deciding to undergo Clear Lens Extraction, there are several factors that need to be considered. Firstly, it is crucial to have a thorough eye examination to determine if you are a suitable candidate for the procedure. Your optometrist will evaluate your overall eye health and discuss your expectations and goals for vision correction.
 

Age is another important factor to consider. CLE is typically recommended for individuals over the age of 40 who have developed presbyopia, a condition that affects near vision. It is also important to have stable vision, as any changes in prescription can affect the accuracy of the IOL power calculation.
 

Additionally, it is essential to understand the potential risks and complications associated with the procedure. While CLE is generally safe, there is a small risk of infection, bleeding, and retinal detachment. Your optometrist will discuss these risks with you and address any concerns you may have.

When it comes to diagnosing and managing complex vision conditions, precision matters. One of the most advanced tools is Medmont topography - a state-of-the-art technology that provides highly detailed maps of the cornea. Whether you are being evaluated for specialty contact lenses, dry eye treatment, or refractive surgery, Medmont topography plays a critical role in delivering accurate, customized care. 

What Is Medmont Topography? 

Medmont topography refers to corneal imaging performed with the Medmont E300 Corneal Topographer, a diagnostic device designed to capture detailed curvature measurements of the cornea. 

Using advanced Placido disc technology, the system projects illuminated rings onto the cornea and analyzes their reflections. From this data, it generates a color-coded map that reveals the shape, elevation, and curvature of the cornea with exceptional accuracy. 
 

Why Is Corneal Topography Important? 

The cornea is responsible for approximately two-thirds of the eye’s focusing power. Even subtle irregularities can significantly affect vision. Medmont topography allows your eye doctor to detect and monitor: 

• Keratoconus and other corneal ectasias

• Corneal irregularities or scarring

• Post-surgical corneal changes

• Astigmatism patterns

• Contact lens fitting complications

• Early signs of corneal distortion 

Because it provides highly detailed imaging, Medmont topography often identifies changes long before they become noticeable in a routine vision exam. 
 

How Medmont Topography Improves Contact Lens Fitting 

For patients who require specialty contact lenses - such as scleral lenses, hybrid lenses, or lenses for keratoconus - precise corneal mapping is essential. 

• The Medmont system offers: 

• High-resolution curvature data

• Wide corneal coverage

• Repeatable, reliable measurements

• Advanced software analysis 
   

This allows your doctor to design and fit custom lenses with greater accuracy, improving comfort, stability, and visual clarity while reducing trial-and-error fittings. 

In September 2025, the FDA approved Stellest lenses for children ages 6 to 12 to correct and manage myopia, a major milestone for myopia care. These lenses have been successfully used in countries across Europe, Canada, and Asia since 2020, showing promising results in slowing eye growth associated with myopia.
 

The Importance of Early Myopia Management

Myopia typically begins in early childhood, often between the ages of 6 and 10, and tends to worsen quickly during the school years as children spend more time reading and using digital devices. The sooner it begins, the higher the risk that it will progress to more severe levels. Every increase in myopia level significantly raises the risk of eye health complications later in life, such as retinal detachment or glaucoma.

By beginning myopia management as soon as possible, parents can help slow eye growth and protect long-term vision. With innovative options like Stellest lenses, families now have effective, science-backed solutions to take control of their child’s myopia.
 

What Are Stellest Lenses?

Stellest lenses are a groundbreaking innovation in myopia control, developed by Essilor. They look like regular eyeglass lenses but are designed with specialized optical technology to both correct vision and slow the progression of myopia.

Thanks to the advancement of lens technology, glasses lenses are no longer a single, one size fits all solution. There are a variety of different lens types that can be used in glasses, giving patients greater flexibility and control over their vision than ever before.

Single Vision Lenses

Also known as monovision lenses, these lenses are designed to correct the wearer’s vision at just one distance, and have a single prescription covering the entire surface of the lens. They are most often recommended for people who are either nearsighted (myopia) or farsighted (hyperopia) and who need glasses for a specific activity, such as driving or reading.

Progressive Lenses

Progressive lenses are multifocal lenses that can correct a patient’s vision at different working distances, ranging from far distance to reading distance. However, rather than designating different areas on the lenses for different distances with visible lines separating them, progressive lenses have a gradual change so that the wearer can smoothly transition from one lens power to another.

Bifocal and Trifocal Lenses

As you may have guessed from the name, bifocal and trifocal lenses have either two or three lens powers depending on which type you choose. Bifocal lenses support distance vision in the top half of the lens, and near vision in the lower half. Trifocal lenses support distance vision in the top third of the lens, intermediate vision in the middle segment and near vision in the bottom third. Whichever variety you choose, you will see visible lines separating each segment.

Bifocal and trifocal lenses are recommended for patients who are near or farsighted, and those who develop presbyopia, which is the natural hardening of the eye lens, that occurs as we get older. Presbyopia makes it harder for the lens of the eye to adapt to focus at different distances.

Multifocal Lenses

Multifocal lenses are the alternative name given to bifocal, trifocal and progressive lenses.

Neuro-Optometric Rehabilitation

When most people think about vision problems, they picture issues with the eyes themselves. However, many visual difficulties actually begin in the brain. After a concussion, stroke, or other brain injury, the connection between the eyes and brain can be disrupted - causing symptoms that affect balance, reading, focus, and even daily comfort.
 

Brain Injuries and Vision

Your visual system is complex - about 70% of the brain is involved in vision processing. After a traumatic brain injury (TBI), concussion, or neurological event such as a stroke, the pathways that coordinate eye movement, focus, and perception can become impaired.

This can result in symptoms such as:

• Blurred or double vision

• Eye strain and headaches

• Difficulty reading or focusing

• Dizziness or balance problems

• Light sensitivity

• Problems with depth perception
   

These visual issues often persist long after other symptoms of a brain injury have improved, making specialized vision care essential for recovery.
 

What Is Neuro-Optometric Rehabilitation?

Neuro-optometric rehabilitation is a specialized form of vision therapy designed to retrain how the brain and eyes work together. Unlike traditional eye care that focuses on eyesight alone, this therapy targets the neurological processes behind vision. Our doctor evaluates how the eyes and brain communicate and creates a personalized treatment plan to rebuild these visual pathways. The goal is to restore comfort, coordination, and clarity - improving overall visual function and quality of life.

Migraines are a debilitating neurological condition that affect millions of people worldwide. One of the most common and disabling symptoms of migraines is light sensitivity, also known as photophobia. This heightened sensitivity to light can be a significant source of discomfort and pain for those suffering from migraines, making it difficult to function during an attack.

Photophobia is a common symptom of migraines, with up to 80% of migraine sufferers experiencing sensitivity to light during an attack. This sensitivity can be triggered by various types of light, including natural sunlight, fluorescent lighting, and even the glow of computer screens or smartphones.

Colored contacts have become increasingly popular over the years as a way to enhance your look and experiment with different eye colors. Whether you want to change your eye color for a special occasion or simply for everyday wear, colored contacts offer a fun and versatile option.

Different Types of Colored Contacts

When it comes to colored contacts, there are various types to choose from, depending on your preferences and needs. The three main categories are cosmetic, enhancement, and opaque lenses.
 

Cosmetic lenses are designed to completely change the color of your eyes. These lenses come in a wide range of shades, from natural hues such as blue, green, and brown, to more vibrant colors like purple, gray, and even red. Cosmetic lenses can create a dramatic transformation and give you the eye color you desire.
 

Enhancement lenses, on the other hand, are designed to enhance your natural eye color rather than change it completely. They add depth and intensity to your eyes, making them appear brighter and more vibrant. Enhancement lenses are ideal if you want a subtle change that enhances your natural beauty.
 

Opaque lenses are specifically designed to cover dark-colored eyes. They are ideal for individuals with naturally dark eyes who want to achieve a lighter or more vibrant eye color. Opaque lenses are often used in theatrical or costume applications as they can create a striking and captivating look.

Dry eye is a common condition that occurs when your eyes do not produce enough tears or when the tears evaporate too quickly. This can result in discomfort, irritation, and a gritty sensation in the eyes. Understanding the causes and symptoms of dry eye is crucial for finding effective treatment options. Tyrvaya offers a breakthrough solution for dry eye relief.
 

What Causes Dry Eye?

There are several factors that can contribute to the development of dry eye. The meibomian glands are responsible for producing the oily component of the tear film, which helps prevent evaporation of tears and maintains a smooth ocular surface. Meibomian gland dysfunction occurs when these glands become blocked, leading to a decrease in the quantity and quality of the meibum. This can result in evaporative dry eye, discomfort, and inflammation of the eyelid margins.

Another common causes is age. As we get older, our tear production tends to decrease, making us more prone to dryness. Hormonal changes, such as those that occur during menopause, can also affect tear production and lead to dry eye.

Environmental factors can play a role as well. Dry or windy climates, air conditioning, and excessive screen time can all contribute to dry eye. Additionally, certain medications, such as antihistamines and antidepressants, can cause dryness as a side effect.

Other underlying health conditions, such as autoimmune diseases like Sjogren's syndrome or rheumatoid arthritis, can also contribute to dry eye. In these cases, the body's immune system mistakenly attacks the tear glands, leading to reduced tear production.

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.
