Keratoconus Soft Contact Lenses – Keratoconus is a type of bone disease that causes thinning and swelling of the bone. Since the cornea is an important part of the eye responsible for giving you clear vision, any irregularities or changes in its shape can distort your vision. If you suffer from keratoconus, your eye doctor will prescribe a special keratoconus medication to help improve your vision.
In the video below, Dr. Jackie Garlich talks about what you need to know before getting contacts for keratoconus.
Keratoconus Soft Contact Lenses
These lenses often do not work well for people with keratoconus. Why? Soft contacts cover the cornea unintentionally and people with keratoconus often need a hard contact lens to correct their corneal irregularities. A soft lens is flexible enough to do this.
Contact Lenses For Keratoconus
These lenses work better than soft contact lenses in keratoconic eyes because of their complex shape. Keratoconus patients have an uneven cornea, so using a hard lens over their irregular eyelid creates a smooth surface. This allows them to see more clearly than soft glasses.
These lenses have a hard core and a soft peripheral, which is often preferred over conventional oil permeable lenses.
These are hard contact lenses that rest on the white of the eye and are larger than standard contact lenses. Their general symptoms are in the shape of a small bowl that you have to fill with saline solution before putting it in your eyes. Vault lenses (or curves) cross the eyeball to give you a clearer vision than soft contact lenses or standard RGP options.
Depending on the severity of your keratoconus diagnosis, one lens may be a better choice than another. Talk to your eye doctor to find out which lenses will work best for you for keratoconus.

Keratoconus is a degenerative eye disease that causes the cornea to become thin and swollen. Irregular like a cone. Since the cornea is responsible for refracting most of the light entering the eye, any irregularity of the cornea can cause blindness. Keratoconus usually occurs in a person’s youth; Although it is diagnosed in people in their forties and fifties. The eye disease is estimated to affect one in 2,000 people in the general population. There is no significant geographic, gender, ethnic, or social stratification, and keratoconus occurs in all regions of the world.
The exact cause of keratoconus is unknown; However, there are many theories that can cause this disease. It is important to remember that there is no theory that tells the whole story, and keratoconus is caused by a combination of factors.
Genetics: Although keratoconus sometimes affects more than one member of the same family, research now shows that the blood relatives of a person with keratoconus are less than one in ten. in the formation of keratoconus.
Simplify Your Lens Fitting
Environmental factors: Keratoconus can be associated with excess UV rays from the sun, excessive eye rubbing, contact lenses, and eye pain.
Endocrine disorders: Another hypothesis is that endocrine disorders (which determine the release of hormones) may be involved, because keratoconus is often diagnosed in adolescence.
The first symptoms of keratoconus are blurred vision and frequent replacement of prescription glasses. However, many types of eye diseases can cause blindness and blurred vision, so if you notice a change in vision, it is important to consult an eye doctor immediately. Keratoconus is usually more severe in one eye than the other eye. Additional symptoms of keratoconus include:
Keratoconus is usually treated with contact lenses because glasses cannot correct the irregular shape of the cornea. Surgical treatments are also available and are often used when preventing contact lens wear.
How To Treat Dry Eyes With Scleral Lenses?
Hybrid contact lenses are the newest and most popular option in contact lenses specifically designed for patients with keratoconus and poor eyesight. Using advanced technology, the hybrids offer the best of both worlds – the vision of high-oxygen gas permeable (RGP) protective lenses and everyday comfort and flexibility eight of the lens sold. Hybrids are specially designed to treat vision in patients with different types and stages of keratoconus. Because the lens forms vaults over the cornea, there is less risk of corneal scarring, making hybrid lenses a treatment option for keratoconus. In addition, the soft skirt of the design makes the face connected to the center of the eye no matter where it is on the cornea or how big it is, reducing visual disturbances and give a better view. The hybrid design prevents dirt from getting under the lens and will not come out unexpectedly. No other protective lens available today can provide all of these benefits in one product.
RGP lenses are made of hard material that forms a layer of tears between the cornea and the back of the lens, instead of sliding over the iris like normal and keeping its shape. This tear layer neutralizes the negative image of the corn. Therefore, RGPs provide better vision than soft contact lenses. Unfortunately, for people with keratoconus, RGPs may not provide adequate vision correction. This is because RGB lenses move to the center of the cone, which is usually not on the eye near the center of the cornea. Because of this, patients wearing RGPs often experience problems with uneven vision. In addition, RGPs are often uncomfortable, cause problems, allow dirt to get under the lens, and can come off. Because most of them are designed to touch the face of the cone, they can cause eyebrow scarring.
Scleral lenses are large RGP lenses that can provide adequate vision, but often require accuracy and precision from your optician. Sclerals are occasionally removed and fresh saline is placed back in during the day to keep your vision clear and comfortable.
The soft tissue reaction is comfortable, but most of the time it is not possible to see the irregularity of the bone and therefore there is no good visualization. Soft lenses overlap the unevenness of the cornea and the face mask will be used for the same condition as the cornea. These abnormal structures are responsible for blindness and vision loss. Because the cornea is not good, the lenses are not good.
Treat Keratoconus With Contact Lenses By Keratoconus
“Piggyback” lenses are RGP and soft lenses worn at the same time. In some cases, this method will be more successful than soft contact lenses or RGP lenses, but due to problems in handling and maintenance, eye health problems may occur. try because of the reduced oxygen entering the cornea through both lenses. Lens centration, the success is marginal.
Keratoconus patients often ask, “Can I have surgery to correct my keratoconus?” There are surgical options designed to strengthen, restore, or replace the irregularity of the cornea and reduce the effects of keratoconus, but unfortunately nothing stops the growth that has happened.
The most common surgical options for keratoconus are: Intacs®, corneal collagen cross-linking, corneal transplantation, or some combination of these procedures.
Intox are semicircular plastic implants that are placed in the center of the cornea. Its purpose is to improve the iris to improve vision. Intacs often do not leave the iris in a perfect shape, and people still need treatment. Intox is used to improve a patient’s vision and delay or eliminate the need for bone surgery.
Revolutionary Keratoconus Treatment Options
A new treatment called corneal collagen cross-linking (CXL) is currently undergoing FDA clinical trials in the US to determine its safety. Through the corneal cross-linking process, customized riboflavin drops saturate the cornea, which is then activated by UV-A light. This process has been shown in clinical and clinical studies to increase the amount of collagen cross-linking and strengthen the cornea.
The bone transplant requires removing about 7.5 mm of the plug – with the highest, most irregular part of the bone – and replacing it with bone from a free eye. Then the transplanted tissue is sutured in place. Lamellar keratoplasty is a new procedure in which only part of the cornea is removed. The theoretical benefit is a lower rate of rejection because the main target for bone rejection is unchanged. The result cornea
