Contact lenses can be a cradle-to-grave solution for people needing help with their vision, but standard lenses may not be suitable for everyone.

If you want to wear contact lenses but have had trouble wearing them in the past — perhaps the contours of your ocular surface make it uncomfortable or you have a condition such as keratoconus — then scleral lenses could be the answer.

These large gas permeable lenses offer the exact same advantages as conventional GP lenses when compared with soft contact lenses, including:

  • Sharp vision
  • Increased durability
  • Easy-to-fit
  • Reduced risk of complications

Scleral lenses do not just cover a portion of the cornea in the way that conventional gas permeable lenses do. Instead, they straddle the entire corneal surface and sit on the ‘white’ of the eye (known as the sclera).

Due to their size, scleral lenses are more stable than conventional gas permeable lenses. The chances of accidentally becoming dislodged from the eye are greatly reduced and this extra degree of comfort makes them comparable to soft lenses, particularly if your eyes are sensitive or your corneas are irregularly shaped.

All modern scleral lenses are made with highly breathable, rigid gas permeable lens materials. Therefore, although scleral lenses cover the entire cornea, plenty of oxygen reaches the front surface of the eye, ensuring it remains healthy and comfortable.

Anyone interested in achieving the best possible vision with the help of contact lenses can be fitted with scleral lenses, even children.

Sclerals can also be an effective solution for people with particualar eye conditions.

  • Irregular corneas.Vision problems caused by an irregularly shaped cornea — whether naturally occurring, due to an eye condition such as keratoconus, or resulting from eye surgery — typically cannot be fully corrected with glasses or soft contact lenses. Scleral lenses typically will provide sharper vision for these eyes.
  • Hard-to-fit eyes.If your eyes cannot be comfortably fitted with conventional GP lenses or the shape of your eye causes the lenses to dislodge too easily from your eyes during physical activity such as running or playing sport, scleral lenses can provide a more comfortable and secure fit.
  • Dry eyes. If your eyes are considered ‘too dry’ for conventional contact lenses, scleral lenses can help. In particular, the extra space between the back surface of full scleral lenses and the cornea acts as a tear reservoir to keep the front of your eye more moist and comfortable.

Here at TK&S Optometrists we offer five different designs of scleral lens and we can also offer our revolutionary EyePrint Pro technology to produce a completely bespoke scleral lens matched to the exact contours of your eye.
