Management of Cataract in Patients with Keratoconus

Keratoconus is the most common ectatic condition affecting the cornea in the middle-aged population, which has been known for more than a century till now [1]. It is most commonly diagnosed in the late teens or early twenties, but may appear in children [2,3]. The widely used corneal topography and now tomography are the cornerstones for diagnosis and classification of corneal ectasia, specially Keratoconus, which gave ophthalmologists an opportunity to diagnose and manage these conditions earlier than before with better visual outcomes [4]. Keratoconic patients suffer progressive corneal thinning with progressive irregular astigmatism and myopia. Patients with early Keratoconus complain of progressive blurring of vision, manifested by frequent changes in their spectacles prescription. Moderate stages are characterized by loss of the best corrected visual acuity with characteristically high astigmatism. Late stages are characterized by severe corneal thinning, descemet membrane tears, corneal hydrops and corneal scarring [5].
