Scleral contact lenses are large-diameter gas permeable contact lenses that vault over the cornea and rest on the "white" of the eye (the sclera). In doing so, the lenses form a dome over the irregular cornea that provides clear and comfortable vision for individuals with keratoconus, dry eye and other ocular surface conditions.
Here are 5 facts about scleral lenses and why they are a great choice for many patients.
1- They work when nothing else will.
Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition or complications following surgery, can at times develop vision problems that cannot be corrected using glasses or soft contact lenses. In such cases, scleral lenses provide a more comfortable, stable, secure fit, and improved vision.
For those with keratoconus, scleral contact lenses provide advanced care that resolves visual distortions and creates clear vision while providing a comfortable wearing experience.
In addition to helping those with keratoconus, scleral lenses are also recommended for those with an astigmatism, particularly for high astigmatism that other contacts cannot comfortably correct.
2- Scleral contacts provide relief for those who suffer from dry eye.
Unlike traditional contact lenses, scleral lenses minimize eye irritation. Since they vault over the dry, irritated cornea and sit on the sclera, they offer comfort and clear vision. Sclerals leave a space between the lens and the cornea containing a liquid reservoir of artificial tears that provides a protective cushion that soothes the eye.
This is crucial, because even blinking can irritate the eye or injure the cornea due to the mechanical friction of the eyelids on the cornea. Scleral lenses can act as a shield between a patient’s eyes and their eyelids, protecting the eyes from further irritation or damage.
3- Sclerals are long lasting lenses.
Constructed from high quality, durable materials, these rigid gas permeable contacts typically last 1-3 years. Therefore, while the initial cost of scleral lenses is higher than standard contacts, you’ll benefit from maximum value for your money.
While scleral lenses are long lasting, it is important to book follow up visits with your eye doctor to determine when it’s time to replace them with a new pair, so as not to harm your cornea.
4- Scleral contacts are worth the cost
People assume that because sclerals must be fitted and customized to fit each individual eye, they are exorbitantly expensive. In fact, the lenses are often covered by insurance and certain vision and health savings plans.
These lenses provide enough of an improvement over regular lenses — in both comfort and vision — to justify the investment.
5- Scleral lenses are very comfortable.
Some people mistakenly assume that rigid contacts aren’t comfortable. In reality, scleral contact lenses are very comfortable because they don’t touch the cornea and lubricate the eyes.
If you have irregular corneas, dry eye or hard-to-fit eyes, scleral lenses may be right for you. Find out more about scleral lenses by scheduling an eye exam at Specialty Contact Lens Center At Advanced Eyecare Center today!
