In cases of mild and stable keratoconus with astigmatism and low myopia (short-sightedness), whenever the eye can handle it, a pre-crystalline intraocular lens implant (behind the iris and in front of the crystalline lens) can be considered in order to correct your prescription. It is important to remember that corneas with keratoconus are anomalous corneas that can respond unpredictably to any surgical manoeuvre performed (for example, an incision or cut in the cornea to insert the lens into the eye). These eyes have a higher risk of retaining part of the prescription than normal eyes.
