Scleral Contact Lenses For Keratoconus – The Keratoconus Group is a safe, supportive community for people living with keratoconus and their carers.
Almost a year ago I got my first pair of scleral lenses. I was overjoyed because I could finally see more clearly than I had ever seen before! But about 2 weeks after I got the contacts the trouble started.
Scleral Contact Lenses For Keratoconus
The right lens will start fogging up after 2 hours and there will be a yellow ring around the light. Every time I blink I will see little circles move up in my field of vision. Taking it out and putting it back in solved the problem for another 2 hours. Called the contact doctor, I told him the problem with the lens. Going down has been provided with a second lens.

Lens #2 lasted half an hour with similar results. Get it already mounted for the third lens. That one caught my eye, it was scary trying to get it out…
Bring it back and the #4 and #5 lenses are just as bad. Lens number 6 lab sent error. It lasted 35 minutes. In the end lens 7 was slightly better than the first lens. But after 2-3 hours it still has lather and lather.
When I called back and told them again if the same result happened with the lens, I was told that nothing more could be done with the lens. Obviously upset that the original problem was still unresolved, I began looking for a new contact lens doctor. After I found one, I went to her and discovered that the contacts I was wearing were not properly seated. I have had Keratoconjunctivitis from contacts. Eye drops (which I absolutely hate) I was given to help with keratitis. A right lens has been installed. Currently I am still waiting for the insurance company to answer yes or no, contact me then. At that moment the first contact doctor called and said they had a consultant coming in and she wanted to see me. I went in and got the new pair, both contacts faded completely after 45 minutes, and now when I call back, I’m wearing the old set until I can make a new one.
This whole experience has been over the past year. It is frustrating at work to have to change contacts every hour. There were many comments and looks when I inserted and removed them. If I had a dollar for every time I heard “Why don’t you have glasses?” Or you don’t know how to enter your contacts as usual, I’d be rich now. and the amount of brine I’ve been involved with is crazy, about 100 boxes a week.

Hopefully the long awaited game will end soon and a new lens will actually work. It’s hard to be optimistic but I’m learning to be patient and deal with it.

In these conditions, vision often cannot be corrected with glasses or soft contact lenses. The use of specialized scleral and hybrid contact lenses significantly improves vision and enables patients to perform daily tasks. I will summarize the conditions that will benefit from dedicated scleral and hybrid contact lenses and also talk about what scleral and hybrid contact lenses are.
Therapeutic Uses Of Scleral Contact Lenses For Ocular Surface Disease:
Keratoconus is a slow, progressive, degenerative corneal disease. This condition causes the cornea, the clear layer in front of the colored part of the eye, to thin and swell. Although the condition has been studied extensively, the cause is not fully understood. A gene in the family line along with environmental factors is a risk factor for developing keratosis. Environmental factors including allergies, eye rubbing and contact lens wear are thought to cause keratosis pilaris. As this condition progresses, it causes vision loss that cannot be corrected with glasses and soft contact lenses. Cannot be cured; but there are many treatment options to slow the progression. Special contact lenses such as scleral and hybrid lenses are used to restore vision.
Perforating keratoplasty is an operation where the cornea is removed and replaced with a graft. After surgery, the cornea is imperfect and does not have a strong refractive surface, resulting in blurred vision that cannot be corrected with glasses. Multifocals and hybrid lenses provide ways to correct vision that glasses cannot.
In some cases of astigmatism, the front part of the eye is shaped like a football. Glass will fix this situation. Soft contact lenses will also correct this; but with higher amounts of astigmatism, fluctuating vision can occur. Specialized hybrid contact lenses eliminate fluctuating vision problems for regular soft contact lens wearers. Soft lenses bend and mold to the shape of the eye. Hybrid lenses work by creating a hard surface to correct astigmatism.
Scleral contact lenses are large diameter contact lenses that surround the entire cornea. It is made of breathable material and is rigid in nature. The scleral contact lens is filled with a saline solution and then inserted into the eye. A saline solution is wrapped between the contact lens and the front surface of the eye, correcting any abnormalities in the cornea. Scleral contact lenses are replaced every year, which means you will wear the same type of contact lens for a year. Scleral contact lenses are not approved to be worn while sleeping.
New Tools To Tame Keratoconus
Hybrid contact lenses are lenses that have the characteristics of both soft contact lenses and rigid gas permeable lenses. The center of the hybrid contact lens is made of a hard gas permeable material and the edge is a soft contact lens material. Hybrid lenses combine the comfort of soft contact lenses and the clarity of hard gas permeable contact lenses. Hybrid contact lenses fit the eye just like regular soft contact lenses. Hybrid contact lenses are replaced every six months, meaning you will wear the same lenses for six months. Combination contact lenses are not acceptable for sleeping.
Both scleral and hybrid contact lenses require a little extra practice to become adept at fitting and removing. I or our staff at Two C Eye Care in Manvel, TX will teach you how to properly care for these specialized contact lenses.
In summary, scleral and hybrid contact lenses are used to restore or improve vision in patients with keratosis or those who have undergone a corneal transplant. These types of contact lenses are also beneficial for patients who want to avoid the visual fluctuations caused by conventional soft contact lenses.
If you have any of these conditions and want advice, make an appointment with Two C Eye Care.

If you’ve been told in the past that you can’t wear contact lenses because of an irregular cornea or other problems, you may want to get a second opinion and ask your eye doctor about scleral contact lenses.
Scleral contact is a large diameter gas permeable contact lens. By doing so, the scleral lens works to replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconush out.
In addition, the space between the cornea and the back surface of the vitreous lens acts as a reservoir for fluid for comfort for people with severe dry eye https://www.allaboutvision.com/conditions/dryeye.htm wear.
Keratoconus Management Prioritizes Corneal Gp Lenses
Scleral contacts are significantly larger than standard gas permeable (GP) contacts and have a diameter equal to or larger than that of soft contact lenses. The smallest grafts are approximately 14.5 mm in diameter and the largest can be up to 24 mm.
Large diameter semi-dural and radius GP lenses rest on the sclera and dome above the keratoconus in people with keratosis, for better vision.
The average human cornea is approximately 11.8 mm in diameter, so even the smallest contacts are designed to cover the entire cornea.
Meanwhile, most conventional GP contact lenses are 9.0 to 9.5 mm in diameter and cover only 75 to 80 percent of the cornea.
