Diagnosis and management of postrefractive surgery ectasia.

Postrefractive surgery ectasia is a serious, sight-threatening complication seen after the following procedures: laser in situ keratomileusis, photorefractive keratectomy, small-incision lenticule extraction, radial keratotomy, and/or arcuate keratotomy. Specific risk factors may include age, corneal thickness, degree of refractive error, corneal topographic changes including irregular astigmatism, percent tissue ablation, and residual stromal bed. Biomarkers may be a new option to help indicate who is at greatest risk for ectasia.

Use of Topical Insulin to Treat Refractory Neurotrophic Corneal Ulcers.

Purpose: To report the clinical course of 6 patients with refractory neurotrophic corneal ulcers that were treated with topical insulin drops.

Methods: Retrospective chart review of patients who had neurotrophic corneal ulcers or epithelial defects refractory to standard medical and surgical treatment. Insulin drops, prepared by mixing regular insulin in artificial tears with a polyethylene glycol and propylene glycol base at a concentration of 1 unit per milliliter, were prescribed 2 to 3 times daily.

Patient satisfaction and clinical outcomes with laser refractive surgery performed by surgeons in training.

Purpose: To evaluate the refractive error quality of life (RQL) improvement, patient satisfaction, and clinical results of laser refractive surgery performed by residents or fellows.

Setting: Department of Ophthalmology and Visual Sciences, University of Wisconsin, Madison, USA.

Design: Case series.
