Many patients have common questions when it comes to scleral lenses.
In this article, I'll address some of the most frequently asked questions I receive from those interested in wearing scleral contact lenses.
What are scleral contact lenses?
A scleral contact lens is a specialized hard lens designed to correct corneal irregularities in certain patients.
These lenses function as a "second cornea," vaulting over the patient’s natural cornea to create a smooth refractive surface for clearer vision.
They are typically used for patients whose vision cannot be fully corrected to 20/20 with glasses or soft contact lenses.
What diseases and conditions indicate a scleral contact lens?
Scleral contact lenses are often used to correct irregularities caused by hereditary corneal dystrophies like keratoconus, corneal scarring from past infections, or significant corneal astigmatism present since childhood.
Additionally, they can provide relief for patients with advanced dry eye disease by continuously hydrating the cornea with a layer of saline solution.
Are scleral lenses comfortable?
The large diameter of scleral lenses offers exceptional comfort for patients.
Before insertion, the lens is filled with preservative-free saline, which provides continuous hydration to the cornea throughout the entire day of wear.
This combination results in a highly positive and comfortable experience for the wearer.
How long does it take to get used to scleral contact lenses?
This depends on the patient. On average, most patients adapt to wearing scleral contact lenses in 7-10 days or less.
How long can scleral contact lenses be worn?
As long as a patient is comfortable doing so in a single day. Many people their lenses for 12-14 hours per day.
Why do scleral contact lenses get foggy?
The most common reasons scleral contact lens fogging occurs are a poor fit or a build up of debris in the tear film.
Can you sleep with scleral contact lenses?
No. I do not advise patients to sleep in scleral contact lenses.
Are scleral contact lenses dangerous?
No. Scleral contact lenses are not dangerous when fit and prescribed by an eye care professional.
What is the lifespan of a scleral contact lens?
This depends on how you care for the lenses. Like other rigid gas permeable contact lenses, you can anticipate your scleral lenses to last approximately 1 to 3 years.
Can scleral contact lenses be used to manage the symptoms of dry eye disease?
Absolutely! Patients with chronic dry eye who do not experience relief from artificial tears are great candidates for scleral lenses.
Final thoughts on scleral contact lens FAQs
Scleral contact lenses have become more accessible thanks to advancements in materials and optics. They now serve a broader range of patients and are an excellent option for those with irregular corneas or dry eye disease.
