Femtosecond laser-assisted DSAEK is not the method of choice, and needs further technical improvement. However, failed femtosecondlaser-assisted DSAEK grafts did not show significant histological changes related to the technique to explain reduced visual acuity. In microkeratome-assisted DSAEK, the preparation time point of the graft does not seem to influence the visual and optical outcome.

Topical calcineurin inhibitors (cyclosporin A 1%, FK506, pimecrolimus) can be useful for treating chronic blepharokeratoconjunctivitis in addition to lid hygiene and lubricants. This treatment leads to an improvement of dry eye symptoms and reduces inflammation.

We present the case of a 45-year-old patient with severe atopic disease and keratoconus who suffered from corneal melting following cross-linking and deep anterior lamellar keratoplasty (DALK) due to subclinical infection with Herpes simplex virus (HSV). Penetrating keratoplasty and intensive antiviral and immunosuppressive medical treatment were necessary to control the infection. The case demonstrates the difficulties in the treatment of keratoconus in patients with severe atopic disease.
