Dacryocystorhinostomy for Acquired Nasolacrimal Duct Stenosis in the Elderly (≥80 Years of Age).

Purpose: The incidence of acquired nasolacrimal duct obstruction (NLDO) increases with age. Dacryocystorhinostomy, the definitive treatment for NLDO, has a high success rate (80%-100%) with a low complication rate (1%-6%), but surgical outcomes have not been reported previously specifically for an elderly population, in which there may be increased risk for intraoperative and postoperative complications. The purpose of this study was to examine surgical outcomes and complication rates of dacryocystorhinostomy in an elderly population.

Corneal endothelial cell changes 5 years after laser in situ keratomileusis: femtosecond laser versus mechanical microkeratome.

Purpose: To compare corneal endothelial cell density (ECD) and morphology between flap creation with a femtosecond laser and flap creation with a mechanical microkeratome 5 years after laser in situ keratomileusis (LASIK).

Setting: Mayo Clinic, Rochester, Minnesota, USA.

Design: Prospective randomized masked paired-eye study.
