| There is a very large range of lenses, each particular to the individual patient. These lenses are normally only supplied to our own patients who require replacement lenses and who have a current contact lens prescription with us. |

HAPTIC or SCLERAL |
| Scerals are shells which rest on the white of the eye, allowing the optic portion of the lens to bridge the cornea completely. These lenses are for eyes with irregular surfaces, such as after acid damage or road trauma. |

ORTHO-K |
| These are special hard lenses that have a VERY high oxygen transmission and are worn whilst asleep. They are removed in the morning and the eyes stay in their new shape for 2-3 days, before the lenses are once again worn at night. This method is successful up to 4 dioptres. |
