Surgically induced corneal necrotizing keratitis following LASIK in a patient with inflammatory bowel disease.

We describe a case of necrotizing keratitis that developed after laser in situ keratomileusis (LASIK) in a 50-year-old woman with inflammatory bowel disease. The patient had not disclosed her history of a total colectomy for recurrent ulcerative colitis and developed bilateral stromal inflammation and corneal melting along the flap edge with ulceration within 3 days of uneventful bilateral LASIK for myopia. She was aggressively managed with topical and systemic corticosteroid therapy.

Optical formula to predict outcomes after implantation of accommodating intraocular lenses.

Purpose: To analyze the effect of optical parameters on the outcomes of accommodating intraocular lens (IOL) implantation in cataract surgery.

Setting: Department of Ophthalmology, KULeuven University, Leuven, Belgium.

Methods: Thin-lens approximation optics were used to obtain a formula containing the following variables: axial length (AL), mean keratometry (Km), anterior chamber depth (ACD), and presumed anterior shift of the IOL (dACD).
