• When removing a cataract from an eye with keratoconus, is there any benefit to inserting a toric lens for astigmatism?


    Question:

    When removing a cataract from an eye with keratoconus (a cornea that becomes thin and misshapened over time), is there any benefit to inserting a toric lens for astigmatism?


    Answer:

    This is a difficult question, because if the astigmatism is irregular (such as with keratoconus), a toric lens should not be used. If mild or moderate and not too irregular, it may be appropriate. The choice should be made by your surgeon after getting measurements. Sometimes a hard gas permeable lens is the best option after surgery.
