We see many patients at our First Eye Care centers that have been told they cannot wear contact lenses because of an irregular cornea or other problems of the eye. However, that is simply not the case. Scleral contact lenses are a great option for those who have large or irregular corneas. This is because they are large-diameter gas permeable contacts, which are specially-designed to envelop the entire surface of the cornea and sit on the white of the eye (sclera). These specialty lenses are designed to replace the irregular cornea with a smooth optical surface, correcting any vision problems caused by this condition at the same time.
Scleral contact lenses are not new, but many people have never heard of them. These unique lenses have helped countless individuals have clearer, more comfortable vision, without the need for bulky eyeglasses.
Do I Need Scleral Contact Lenses?
If you aren’t sure whether you need scleral contact lenses or not, the first thing you should do is schedule an appointment at one of our three First Eye Care vision centers. We will be able to tell you right away whether or not these types of lenses are right for you. There are three main indications that you are a candidate for scleral lenses:
- Work to improve vision - If you have irregular corneal astigmatism, corneal degenerations, or refractive errors, scleral contact lenses are a great option for you. Not only are they far more comfortable, but they will improve your vision.
- Protect the cornea - People with an irregular cornea or other issues with the cornea need protection, which is something these large-diameter contacts can offer. They also offer protection against dry eye, incomplete lid closure, neurotrophic keratopathy, and Sjogren’s disease.
- Deal for athletes and to improve outward appearance - Scleral contacts are also designed for individuals who play sports or those looking for a cosmetic improvement.
The average human cornea is about 11.8 millimeters in diameter, and most conventional contact lenses are between 9 and 9.5 mm, covering just 75 to 80 percent of the cornea. Scleral lenses, on the other hand, range from 14.5 mm to 24 mm. These lenses are usually gas permeable, meaning they are rigid and designed to stay right on the eye. If you have been told in the past you cannot wear contacts because of an irregular cornea, please contact First Eye Care today and schedule a scleral contact lens fitting. We will work with you to find the lens that works for your particular needs, no matter what it takes.
First Eye Care has three convenient locations in Hurst, Keller, and Roanoke. Please visit one of these for more information on our scleral contact lens fittings, or to schedule an appointment.
