What is CLE/RLE used to treat?

It is used to treat cataracts (replacement lens) and severe refractive errors such as astigmatism, myopia, and hyperopia.

It can also be used to treat ‘keratoconus’. Keratoconus is an eye condition where the front of the cornea appears to bulge outwards. This bulging is caused by a thinning of the cornea which results in a distortion of vision.

Laser eye surgery such as LASIK is not recommended for patients with keratoconus. Why? One of the side effects of LASIK is a thinning of the corneas which can be caused by the removal of corneal tissue. Patients with thin corneas are advised against laser eye surgery and this equally applies to patients with keratoconus.
