Specialty Contact Lenses

Specialty Contact Lenses

Are you having trouble seeing with traditional glasses and contact lenses? Discover the next level of vision care with scleral lenses! These lenses are a game-changer for patients with keratoconous, post surgery complications, corneal irregularities, and other complex vision needs. These lenses are larger than conventional contacts and rest comfortably on the sclera (the white part of the eye).

Every patient is different and so are their eyes. This means that there need to be different types of contact lenses to suit each individual. Some patients have corneal abnormalities which mean that conventional lenses won’t sit comfortably on the surface of their eyes, while others suffer from eye conditions that mean normal contact lenses won’t be comfortable or could irritate their eyes. 

 

Who might be a good patient for specialty contact lenses?

Some of the patients that might benefit from specialty contact lenses include those who:

  • have been diagnosed with dry eye syndrome

  • have corneal scarring

  • have been diagnosed with keratoconus, a condition characterized by the bulging of the cornea

  • suffer from a peripheral corneal thinning disorder

  • are intolerant to other types of lenses


Your eye doctor or contact lens provider will be able to tell you if you need specialty contact lenses and if so, which lenses would be best based on your individual requirements. 
 

Scleral Contact Lenses

Scleral contact lenses are very different to standard contact lenses. This is because scleral lenses are much larger in diameter, with three different sizes available depending on your specific needs. This size difference means that the edges of the contact lens fall on a white part of the eye, called the sclera rather than the cornea. Scleral lenses are also different in that they vault over the surface of the cornea rather than touching it, leaving a space between the front surface of the eye and the back of the contact lens. This makes scleral lenses a good choice for patients with dry eyes and corneal abnormalities. Space can trap tear film which keeps the eyes hydrated, while space also accommodates many corneal abnormalities, such as the bulge associated with keratoconus. 
 

Hybrid Contact Lenses

Hybrid contact lenses are a combination of both soft and gas-permeable contact lenses, giving patients the opportunity to enjoy the best parts of both designs. The middle part of hybrid lenses is made from gas-permeable material that lets oxygen pass through to the eyes. However, the gas-permeable part of the lens is more rigid, and this firmer center gives the lens greater stability and the patient enhanced clarity. The RGP portion of the lens also helps to trap a tear film between the cornea and the lens so that the eye remains hydrated. Meanwhile, the outer edge of hybrid lenses is a soft lens skirt. This means that patients don’t have to deal with the hard edges associated with RGP lenses that may be uncomfortable. Instead, the comfort levels that patients experience are more like wearing fully soft.
