Scleral lenses are ideal for patients with corneal irregularities, dry eyes, and hard-to-fit eyes. Their uniquely large circumference offers the best in visual comfort and clarity. But wearing and caring for your scleral lenses can take some getting used to.

Below are our top 5 tips for anyone who wears scleral lenses. If you have questions about scleral lenses or any other optometric matter, Dr. Terry Tsang Optometry, Inc. in Irvine is here for you.

1. Lens Hygiene is Top Priority

Keeping your scleral lenses hygienic and free of buildup is key in ensuring the clearest possible vision. When you remove them from your eyes, rub them for several seconds with lens cleaner to remove surface debris and bacteria. Then, rinse them on both sides with saline solution before storing them.

Another hygiene tip: Before handling your lenses, be sure to wash your hands with soap and water, and to rinse and dry them with a lint-free cloth or paper towel. Good hygiene will significantly minimize possible complications and keep your eyes feeling fresh.

2. Manage Your Dry Eye

Many patients with dry eye syndrome (DES) choose to wear scleral lenses for their hydrating and soothing properties. While sclerals can offer substantial relief from their dry eye symptoms, patients shouldn’t forget to seek treatment for their DES.

That’s because scleral lenses help manage dry eye, but don’t actually treat it. So, it’s best to follow up with your eye doctor about any eye drops, medications, or at-home remedies to support healthy tears.

3. Use a Cotton Swab For Cleaning

Patients with long fingernails can find it challenging to thoroughly clean their scleral lenses. Rubbing the inside bowl of the lens with a cotton swab and cleaning solution can effectively remove the buildup from the lens. Then, rinse off the cleaning solution with saline to remove the cleaning solution and any lint from the cotton swab.

4. Try Different Insertion Tools

Is your current insertion method not working as smoothly as you’d like? No worries! Ask your eye doctor about different tools you can use, such as the O-ring or applicator ring.

But please only insert your lens with tools that your eye doctor recommends!

5. Follow Up With Your Eye Doctor

Because scleral lenses are customized, they often require a few visits with your optometrist to optimize their fit. Even after the fitting process is complete, follow-ups will help ensure that your lenses are still in good condition.

If your scleral lenses are giving you any trouble at all, we can help. To schedule your scleral lens consultation, call us today!

Frequently Asked Questions with Our Scleral Lenses Expert in Tustin, California:

Q: How do scleral lenses work?

  • A: Scleral lenses rest and vault over the entire sclera (white of the eye), encasing a hydrating reservoir in between the lens and the cornea (front surface of the eye). This allows people with irregular corneas to wear contact lenses, since the lens isn’t in direct contact with the cornea itself.

Q: How long do scleral lenses last?

  • A: Scleral lenses generally last 1-2 years, depending on how well you care for them and how your tear film reacts with them. Even so, check-ups every 6 months are recommended to ensure they still fit well and provide clear vision.

Can I Wear Contacts If I Have Astigmatism?

brunette girl smiling 640Many people choose to wear contact lenses to correct their vision due to the freedom and convenience contacts provide. But for those with astigmatism, wearing contact lenses isn’t always simple.

At Dr. Terry Tsang Optometry, Inc. in Irvine we offer specialized contact lenses that provide clear and comfortable vision, even if you have moderate to severe astigmatism.

What is Astigmatism?

Astigmatism is a refractive error caused by an irregularly shaped cornea. The abnormal cornea causes light to disperse unevenly into the eye, leading to blurred or distorted vision. Other symptoms of astigmatism can include headaches, eye strain, and difficulties with reading or using digital devices.

Astigmatism may be congenital, meaning that you are born with the condition, or you can develop it later in life. People with astigmatism usually also have myopia (nearsightedness) or hyperopia (farsightedness), two of the most common refractive errors.

Which Contact Lenses Can You Wear With Astigmatism?

Although traditional soft contact lenses may not be suitable for patients with astigmatism, there are two other types of contact lenses specifically designed for those with unusually shaped corneas.

Toric Contact Lenses

Toric lenses are a popular choice for people with mild astigmatism. Patients with higher levels of astigmatism, however, generally require a higher level of expertise.

Toric lenses are designed to provide clear vision and a comfortable fit. There are two main issues with toric lenses. First, the range of corrective powers is limited, so patients with moderate to high levels of astigmatism may not be able to wear toric contacts. Second, these lenses need to rotate on the cornea to find the correct position and orientation, leading these lenses to occasionally provide unstable or varying clarity of vision.

Toric lenses are available in either soft disposable or rigid gas permeable (RGP) lens materials.

Scleral Contact Lenses

Unlike standard lenses, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). These lenses do not have the issues faced by toric lenses as they are individually designed for each patient and do not sit on the cornea. By vaulting over the cornea, scleral lenses create a liquid reservoir between your cornea and the lens. This dome provides a continually hydrating environment that protects the cornea, promotes healing, and increases comfort.

Scleral lenses have become a staple therapeutic tool in the visual rehabilitation of patients with astigmatism and other corneal irregularities. They also can provide better visual acuity than standard soft lenses thanks to their rigid surface and personalized fit. Scleral lenses have proven to be an excellent solution for patients with astigmatism that appreciate sharp and comfortable vision.

How We Can Help

At Dr. Terry Tsang Optometry, Inc., we can provide you with customized toric or scleral contact lenses that are tailor-made for patients with astigmatism or other corneal irregularities, as well as hard-to-fit eyes. By taking precise and detailed measurements of your cornea, we will be able to ensure a secure fit and crisp, clear vision. To learn more information or to schedule your consultation, call us today.

Scleral Lenses Can Prevent Dry Eye, Tiredness, and Discomfort

protect your eyes 640x350It’s not uncommon for certain contact lens wearers to suffer from eyes that feel dry, red, itchy, uncomfortable, and at times very painful. Eye drops and artificial tears can deliver relief, but they are no more than a temporary solution.

One of the best contact lenses for optimal comfort and hydration are scleral lenses, as they simultaneously provide vision correction, protect the eyes, and lubricate them.

What are Scleral Lenses?

These rigid gas permeable lenses have an extra-wide diameter that vaults over your whole cornea. In contrast to other contact lenses, they rest on the white part of your eyes (sclera) and not the cornea. As a result, scleral lenses consistently rank at the top of the charts when it comes to providing sharp visual acuity, comfort, and healthy eyes.

Common Contact Lens Complaints

Below we’ll explore the most common contact lens complaints we hear at our practice and ways scleral lenses can prevent them.

End-of-day tiredness and dry eyes

After just 6 to 8 hours of contact lens wear during the day, many contact lens wearers experience tired and dry eyes. Though standard hydrogel contact lenses allow a high concentration of oxygen to permeate the eye, some people need an alternative.

End-of-day eye discomfort can be resolved with scleral lenses, as these custom-designed lenses have a liquid reservoir between the lens and the cornea that provides a continuous moist environment that soothes tired, dry eyes.

Not only does this cushion of moisture lead to a comfortable wearing experience; it also promotes healthy eyes throughout the day, allowing you to wear these lenses for 12 to 14 hours! It is for this reason that many of our patients turn to scleral lenses for unparalleled comfort and all-day ocular hydration.

Chronic dry eye syndrome

Certain dry eye patients may experience painful, red, and swollen eyes. For them, traditional soft contact lenses can be unbearable because they sit right on the irritated cornea. Moreover, these contact lenses tend to act as sponges, soaking up the moisture from the surface of the eye.

If you struggle with dry eye syndrome and have been looking for a more effective treatment method beyond eyedrops and artificial tears, ask your Dr. Terry Tsang Optometry, Inc. doctor about scleral lenses.

Feeling the contact lens in the eye

Feeling your contact lenses in your eyes often indicates a poor fitting. Everyone’s eyes are different and when it comes to contact lenses, no size fits all. Furthermore, if lenses are insufficiently curved, they can be dislodged with every blink. This isn’t just uncomfortable — the wrong size lens can damage your cornea.

Because scleral lenses have a large diameter and are custom-made to your eye shape and size, it is almost impossible for scleral lenses to dislodge during normal wear. And since these lenses do not make contact with the surface of your cornea, there is a decreased risk of corneal abrasions.

Operating in dusty environments

Dry, dusty or dirty conditions can cause contact lenses to not only dry out, but can also lead irritants to attach themselves to the lenses. Scleral lenses offer comfort, even in dusty or dirty environments. This is because the lenses cover a large area of the eye, and since the outer layer of the lens protects the eye surface, dust and tiny particles can’t reach it. While not a complete barrier, scleral lenses can provide you with more relief and all-day comfort than traditional lenses.

If you’ve tried traditional contact lenses and have experienced any of the above, or if you’re simply seeking a more comfortable alternative to wear all day, it’s worth considering scleral lenses.

Contact a knowledgeable and experienced eye care professional, Dr. Terry Tsang, who will patiently assess and explain your condition to you. Dr. Terry Tsang will perform a specialized scleral lens custom-fitting to ensure that you receive the best fit for optimal visual clarity and comfort.

Call the Dr. Terry Tsang Optometry, Inc. today to schedule your consultation. We help patients from the Tustin, Lake Forest, Newport Beach, and Mission Viejo, in the California area enjoy great vision and comfort with scleral lenses.

Traditional contact lens wearers can at times suffer from eyes that feel dry, red, itchy, and uncomfortable.

This may happen after a long day of wear, having the wrong contact lens fit, or as a result of operating in dusty environments.

Many turn to eye drops and artificial tears for relief, though they offer only a temporary solution.

For optimal comfort and hydration, consider scleral lenses.

They provide not only visual clarity, but also protect the eyes, while ensuring that they remain moist all day long.

Because scleral lenses have a large diameter and are custom-made to your eye, it is practically impossible for them to dislodge during normal wear.

Moreover, scleral lenses decrease the risk of corneal abrasion, as they do not make contact with the surface of your cornea.

What Is the Shape of a Healthy Eye and How Does It Affect Vision?

eyes eye care 640x350The human eye is a biological piece of functional art, capable of producing colorful moving three-dimensional images with high precision. At the same time, one can marvel at the aesthetic beauty of the human eye and its shape.

The Shape of a Healthy Eye

In a healthy and perfectly shaped eye, light passes through the cornea and crystalline lens, and is accurately focused onto the retina, located at the back of the gel-filled eyeball. This process enables an image to be passed onto the optic nerve and then the visual cortex of the brain. Accurate focus and convergence depend on the proper shape of each part of the eye. However, eyeballs can be either shortened (hyperopia) or elongated (myopia).

Unhealthy Eye Shapes That Impact Vision

The Myopic Eye

In an elongated myopic eyeball, the distance between the lens and retina is too long, leading the image to come into focus before reaching the retina. As a result, the photosensitive cells of the retina pick up a blurry image.

The Hyperopic Eye

In hyperopia or farsightedness, the opposite is the case. The eyeball is too short, as is the distance that light travels from lens to retina. Therefore, the image comes into focus behind the retina, causing distant objects to appear clear, whereas close ones do not come into proper focus.

The Cornea

While the crystalline lens is flexible and auto-adjusts its shape for proper focus, the cornea is static. A healthy cornea maintains its smooth dome shape. However, if the cornea is weak, the structure of the cornea cannot hold this round shape, causing the cornea to bulge outward and downward like a cone. Perfect curvature of the cornea ensures the correct bending of incoming light onto the lens, whereas inadequate curvature results in a refractive error.

An uneven or irregularly shaped cornea also distorts the image that forms at the retina. Common corneal irregularities include astigmatism and keratoconus.

Scleral Lenses for a Smooth Eye Shape

Scleral lenses are large contact lenses that rest on the sclera — the white part of the eye. The lenses span over the cornea, making them ideal for a deformed cornea as they even out the irregularity to create a perfectly shaped eye.
