Irregular Corneas

Most corneas (the front window and first lens of the eye) maintain a regular shape throughout life and can be well focused by eyeglasses and contact lenses. Unfortunately, some corneas are damaged by disease or injury, are irregularly shaped, and require specialized rigid contact lenses to provide focused vision. In particular, eyes with keratoconus, pellucid degeneration, radial keratotomy, corneal grafts, extreme astigmatism frequently benefit visually by rigid corneal or scleral lenses. At Stouffville Optometry, we are well equipped, trained, and experienced to be able to identify these types of eyes and fit rigid corneal and scleral lenses for those requiring such lenses.


Orthokeratology is a clinical technique of using rigid contact lens retainers (worn while sleeping) to gently reshape the surface of the eye and thus improve focus and clarity of vision during the day. As it is temporary the retainers must be worn regularly to maintain the effect. This technique has a decades long record of success if utilized well and on eligible eyes. More recently, it has been scientifically demonstrated to reduce the progression into myopia and so we use this technique as part of our myopia control programs. It remains an excellent option for myopic patients of any age to see well without the use of glasses or contact lenses.

  • Scleral lenses still remain the most comfortable and, in many cases, only way, to obtain comfortable, accurate vision for those suffering from severe dry eye, keratoconus and other similar eye conditions.
