Can I wear contact lenses if I have keratoconus?
Traditional contact lenses (“soft” lenses) cannot correct astigmatism, so are not usually able to correct vision acuity in people living with keratoconus. For this reason, Rigid Gas Permeable (RGP) contact lenses – typically called “hard” lenses – are the customary contact lenses prescribed to correct vision in people living with keratoconus.
Are eyeglasses better than contact lenses?
Regardless of the reason or the recovery time, it is a clear reason that glasses are better than contacts. You do not need to worry about any of these things happening with glasses. Allergic reactions are rarer than any other issue when it comes to contact lens use.

Which contact lens is used in keratoconus?
Contact lenses are required for the visual improvement in patients with keratoconus. Various contact lens options, such as rigid gas permeable (RGP) lenses, soft and soft toric lenses, piggy back contact lenses (PBCL), hybrid lenses and scleral lenses are availble.
Can I wear contact lenses with keratoconus?
Contact lenses play an important part in treating keratoconus. The first line of treatment is usually to correct the irregular cornea with rigid gas permeable (RGP) contact lenses, although some people with early keratoconus may be able to wear glasses or soft contact lenses.
Do toric lenses work for keratoconus?
Soft toric lenses: Toric lenses are designed to manage astigmatism. These lenses have advanced a lot over the years to become a comfortable and viable option for treating keratoconus. They may not be specialized enough, depending on your eyes and the degree of the disease.
Are scleral lenses good for keratoconus?
Scleral lenses are effective for correcting vision in persons with keratoconus because they do not require the close surface-matching fit of standard contact lenses. In fact, scleral lenses do not sit on the corneal surface at all.
Why are contact lenses better for keratoconus?
In the early stage of Keratoconus glasses can be used to give a good standard of vision. However, as the condition progresses the cornea becomes more irregular in shape and glasses no longer work. Contact lenses give better vision as they help correct the distortion caused by the corneal irregularities.
What is a hybrid contact lens?
What Is A Hybrid Contact Lens? A hybrid contact lens combines a Gas Permeable (GP) or “hard” lens) centre with a soft skirt to give you the clear, crisp vision of a “hard” lens and the comfort and ease-of-wear of a soft lens.
How much are scleral lenses for keratoconus?
The cost of scleral lenses varies greatly depending on the complexity of the case. Costs typically range from $2,000 to $4,000 or more.
How much do keratoconus contact lenses cost?
RGP lenses should be fit by an eye doctor and the associated costs can be hundreds or even thousands of dollars. Many insurance plans do not cover RGPs based on the premise that they are 'cosmetic'. On average these lenses can cost between $75-325 per lens (2 lenses/annual supply).
How much does a scleral lens cost?
Including all appointments, these lenses cost $1200-2000, including fit and examinations, depending on their complexity. They provide a comfortable solution to vision correction not available in the past for more complicated conditions. HOW LONG CAN I WEAR SCLERAL LENSES DURING THE DAY?
Why are scleral lenses so expensive?
Because the lenses must be fitted and customized to fit each individual eye, there is more work involved in prescribing scleral lenses, which many patients assume will lead to higher cost. Patients are often surprised to discover scleral lenses are not excessively expensive.
How long does a scleral lens last?
Patients can expect their scleral lenses to last about the same length as other rigid lenses, which is anywhere between 1 and 3 years. The longevity of your lenses depends on a few factors, like: If lenses are carefully handled and kept clean. If lenses remain properly-fitted, comfortable, and provide clear vision.
How to restore vision after keratoconus?
Our doctors have restored vision for keratoconus patients who are: 1 Seeking treatment for the first time 2 Currently wearing contact lenses that are not comfortable or do not provide improved vision 3 Considering surgeries such as corneal transplants, corneal implants (Intacs), or corneal collagen cross-linking (CXL)
What is a scleral contact lens?
Scleral contact lenses are large-diameter lenses that provide clear and comfortable vision for keratoconus patients because the lenses do not actually touch the cornea. Instead, scleral lenses vault over the entire corneal surface, resting on the “white” portion of the eye known as the “sclera.”. The space between the back and front portions ...
What is the difference between scleral and semi-scleral contact lenses?
Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. These larger lenses also are more stable than conventional gas permeable contact lenses, which move with each blink because they cover only a portion of the cornea.
What is piggybacking contact lens?
Piggyback Contact Lenses. “Piggybacking” involves placing a soft contact lens over the eye and then fitting a gas permeable lens over the soft lens. This can increase comfort because the soft lens acts as a cushion pad under the more rigid gas permeable lens.
Is keratoconus a time consuming process?
Properly and effectively treating keratoconus is a time consuming process, and thus many doctors are not willing to spend the requisite time. Our doctors stay current on the latest keratoconus management and treatment options and have the experience and compassion needed to restore your vision.
What is RGP contact lens?
RGP contact lenses are commonly used to treat people with keratoconus. “Gas permeable” means that these lenses let oxygen flow through the material to your eyes. They help protect the health of your eyes by allowing them to “breathe.” RGP lenses offer excellent vision correction, but some patients find them hard to wear for extended periods of time. While you may find soft lenses more comfortable, RGP lenses provide significantly better vision correction because they don’t mold to the shape of your eye the way soft lenses do (and it’s the shape of your eye that’s causing your vision problems, after all).
Why do you need a scleral lens?
Scleral contact lenses are the gold standard when it comes to choosing contact lenses for keratoconus because they provide both clear vision and superior comfort. Scleral lenses are designed with a “dome” or reservoir that floats above the eye’s surface. This shape serves multiple purposes. First, it corrects the shape of the cornea and improves vision. Also, this reservoir collects tears, keeping the eyes lubricated and comfortable throughout the day. Scleral lenses are also larger than traditional lenses, so they sit further out on the eye on a less sensitive area. Because the edge of the lens sits under the eyelid, it won’t move around when you blink, either.
What is a piggyback lens?
This system means that you wear a soft contact lens on the eye and a rigid gas permeable or gas permeable lens on top of it. This combination can provide the sharp vision of an RGP lens along with the comfort of a soft lens because the soft lens underneath acts as a cushion and a shield for the surface of the eye. This system may take some getting used to, but it works very well for many individuals. Ideally, the soft lens is a silicone hydrogel lens. It may be a daily, monthly, or two-week disposable lens, as long as the RGP lens that sits atop it is compatible.
Can you wear soft contact lenses with keratoconus?
Soft contact lenses are not a typical choice for keratoconus patients. However, people who find it difficult to tolerate “hard” contact lenses may respond well to custom soft lenses. These lenses may provide less visual clarity, so it’s critical to weigh the importance of comfort versus optimal vision. There are some new products available that may be of assistance, such as special lenses that come in different thicknesses and those made of specific materials that offer better results. Soft lenses are probably the most effective in earlier stages of keratoconus.
How to determine the best contact lenses for keratoconus?
The first step in determining the best contact lenses if you have keratoconus is to schedule a comprehensive eye exam and contact lens evaluation with an eye doctor who specializes in contact lenses. Page published in January 2019.
What type of contact is best for keratoconus?
Generally, scleral contact lenses provide the best fit, comfort and visual acuity for someone with keratoconus. Scleral contacts are larger in diameter than conventional gas permeable (GP) contact lenses, which allows them to vault over even relatively large areas of distorted cornea, eliminating much of the irregular astigmatism ...
Which is better, GP or hybrid contact?
In some cases, conventional GP contacts may be a better choice — especially if the wearer has a difficult time applying and removing larger scleral lenses. Hybrid contact lenses — lenses that have a rigid gas permeable central zone, surrounded by an outer zone made of silicone hydrogel contact lens material — are another good option ...
Do scleral contacts fit under eyelids?
Also, when properly fitted, scleral contacts provide a more stable fit and are less likely to become dislod ged from the eye during sports and other activities. (They fit more securely under the eyelids due to their larger size.) However, the best type of contact lens for keratoconus can vary from person to person.
What type of contact lens is used for keratoconus?
In keratoconus, various types of contact lenses can be used to improve vision: GP – hard gas-permeable, soft, hybrid, scleral, as well as combinations of hard and soft contact lenses (Piggyback).
What is the possibility of correction of the highest degrees of myopia and astigmatism that accompany kerato
possibility of correction of the highest degrees of myopia and astigmatism that accompany keratoconus; their ability to perfectly pass oxygen to the cornea of the eye , which is very important for her health; easy to use and care for lenses; the possibility of their production on the individual order , ie , the shape of the cornea ...
What is a scleral lens?
Scleral lenses are called rigid gas-permeable lenses that at least partially support the sclera (white tissue of the anterior surface of the eyeball) to reduce pressure on the cornea affected by keratoconus and prevent its injury. After all, the usual hard and soft contact lenses are adjacent to the cornea and injure it.
What is a RGP lens?
RGP (rigid gas permeable) contact lenses are the most widely used method of improving vision in patients with keratoconus. These lenses, due to their rigidity, allow to perfectly smooth all the irregularities of the cornea, forming a completely correct front optical surface. In the optical system obtained with the use of GGP lenses, all the rays of light passing through the cornea precisely focus on the retina of the eye.
Why do people wear soft contact lenses?
Soft contact lenses for keratoconus. Made individually soft contact lenses can be used when the patient can not use hard gas-permeable lenses due to discomfort. For the above reasons, soft lenses are often able to improve visual acuity to a much lesser extent than RGP lenses.
Can lenses cause corneal damage?
In the long term, the use of lenses leads to the risk of introduction of infection, trauma of the cornea, development acanthameba keratitis, in which a large percentage of cases result in clouding of the cornea and the need for penetrating or lamellar keratoplasty (corneal transplant). If the keratoconus is stable - the best method ...
Can contact lenses cause scars?
After all, the usual hard and soft contact lenses are adjacent to the cornea and injure it. This mechanical effect on keratoconus can cause the appearance of the scar. To reduce or completely eliminate the pressure of the lens on the cornea, the diameter of the scleral lenses should exceed the diameter of the cornea.
What type of contact lens is best for keratoconus?
Hard contact lenses. Hard (rigid, gas permeable) contact lenses are often the next step in treating more-advanced keratoconus. Hard lenses may feel uncomfortable at first, but many people adjust to wearing them and they can provide excellent vision. This type of lens can be made to fit your corneas. Piggyback lenses.
How to treat keratoconus?
Generally, there are two approaches to treating keratoconus: slowing the progression of the disease and improving your vision.
What is the procedure called when the cornea is saturated with riboflavin?
Therapies. Corneal collagen cross-linking. In this procedure, the cornea is saturated with riboflavin eyedrops and treated with ultraviolet light. This causes cross-linking of the cornea, which stiffens the cornea to prevent further shape changes.
What is the procedure to remove scarring from the cornea?
Penetrating keratoplasty. If you have corneal scarring or extreme thinning, you'll likely need a cornea transplant (keratoplasty). Penetrating keratoplasty is a full-cornea transplant. In this procedure, doctors remove a full-thickness portion of your central cornea and replace it with donor tissue.
What is the best test to detect keratoconus?
Special photographic tests, such as corneal tomography and corneal topography, record images to create a detailed shape map of your cornea. Corneal tomography can also measure the thickness of your cornea. Corneal tomography can often detect early signs of keratoconus before the disease is visible by slit-lamp examination.
Where do scleral contact lenses sit?
Instead of resting on the cornea like traditional contact lenses do, scleral lenses sit on the white part of the eye (sclera) and vault over the cornea without touching it. If you're using rigid or scleral contact lenses, make sure to have them fitted by an eye doctor with experience in treating keratoconus.
What is the protective layer between the eye and contact lens?
Scleral contact lenses cover the white part of the eye and arch over the cornea. A protective layer of saline lies between the eye and contact lens. These lenses are a good alternative to surgery for many patients with keratoconus.
