Scleral lenses are a special type of contact lens that sits on the white of the eye, known as the sclera. These lenses are about the size of a soft contact lens, or slightly larger.
Scleral lenses are more rigid than soft contact lenses and are very comfortable to wear. They also give very clear vision by correcting astigmatism, even for people with high amounts of astigmatism.
If you have been told that you are not suitable for contact lenses, then it may be worth getting a second opinion with our English speaking and considering scleral lenses.
Who can use Scleral lenses?
Scleral lenses are now used by people with corneal disorders such as keratoconus, post refractive surgery such as LASIK, post corneal transplant, trauma to the cornea and others. However, because scleral lenses offer such wonderful benefits, they are also being used for patients who do not have diseased corneas, but for people looking for a comfortable option other than soft lenses.
Conditions that can be treated with Scleral lenses include:
- Corneal transplant patients
- Corneal ectasia
- Post LASIK patients
- People who have severe dry eyes
- People with high amounts of astigmatism
- Post radical keratology or R-K surgery patients
What Benefits are there of using Scleral lenses?
They are an excellent option for people with severe dry eyes and other corneal issues or diseases. They provide great comfort by vaulting the cornea and only touching the sclera of the eye. This means they are safe, easy to place and give excellent, sharp vision.
How are Scleral lenses made?
Every lens is custom made for each individual cornea. Eleven thousand individual points of the cornea are read by the WAVE designer to custom design the perfect lens for each eye, no matter what the prescription is. A special instrument called an OCT maps the alignment across the entire eye to make an exact fit to levels similar to the thickness of a human hair.
Other things to consider with Scleral lenses
A pair of scleral lenses should last about a year if you care for them properly. These lenses are inserted in a similar way to regular contact lenses but are first filled with a gentle non-preserved artificial tear solution. This makes them safe and more comfortable for people to use, especially those who suffer with soft contact lenses drying out during the day. Because scleral lenses are more rigid, most people find them easier to handle than regular soft contact lenses.
If you have keratoconus or corneal transplants then scleral lenses provide an excellent treatment to restore sharp, clear vision. They are also suitable for people with near nearsightedness, far farsightedness, astigmatism and dry eye.
What do Scleral lenses cost?
There are different types and sizes of lenses available. This means that prices can vary a lot from patient to patient depending on the condition and problem faced with each eye. Scleral lenses are personalized and custom made depending on the condition of the eye so costs can only be given after a professional consultation with the specialist.
