Many people don’t realize that not all contact lenses are the same. Innovations in their design now mean that patients who were previously considered unsuitable for contact lenses due to problems such as an irregular cornea can now enjoy all of the benefits that this solution offers. This is thanks to the creation of a type of contact known as scleral contact lenses.
If you experience either of the following issues, you may be a suitable candidate for scleral lenses:
Irregular corneas. While some people are born with an irregular corneal shape, other patients may develop the issue as a result of an eye problem such as keratoconus, a condition characterized by the progressive thinning of the cornea.
Dry eye syndrome. This common condition often resolves itself, but if you suffer from recurrent episodes of dry eye syndrome or associated disorder, you may be a good candidate for scleral lenses. This is because the space between your cornea and the lens can act as a tear reservoir to prevent your eyes from drying out.
Scleral contact lenses have been designed specifically with corneal irregularities in mind. This is because these large diameter, gas-permeable lenses cover the entire surface of the eye – including the cornea and the whites of your eye – which is known as the sclera.
Because they are far more covering than conventional contact lenses, scleral lenses do not have contact with the entire front of the eye. This is important because your eyes need to have access to plenty of oxygen in order to remain healthy and so you don’t experience any side effects such as dry eyes. Instead, their primary contact with the front surface of the eye depends on the type of scleral lens you choose.
There are currently three different types of scleral lens and our experienced and knowledgeable optical experts will be able to advise you which is most suitable for you based on your individual needs. These different types are as follows:
These are the largest of the three and provide the greatest amount of clearance between the back surface of the lens and the cornea.
These extend out over the entire corneal surface, making primary contact with the anterior sclera.
These lenses are much larger than conventional gas-permeable lenses and make contact with the surface of your eye at the junction between the cornea and the sclera.
All types of scleral lenses offer patients the same great benefits which include improved clarity and sharpness of vision, durability, greater stability on the eye, comfortable fit, easier handling and of course, the opportunity to see clearly without the need for glasses which can be inconvenient.
