purpose: to determine the incidence, concurrent factors and clinical results of re-operation after corneal refractive surgeries. methods: in this retrospective descriptive study records of all patients undergoing corneal refractive surgeries including prk, lasik, and lasek between april 2005 and december 2006 were assessed. patients who had undergone re-operations entered the study; visual acui...

Purpose: To provide a summary of the most recent evidence-based data on the paediatric refractive surgery. Methods: A review of the published studies from 1990 to 2015 was undertaken with emphasis on recent articles from 2010 to 2015. Results: Searching Scopus and PubMed, using the keywords of refractive surgery, phakic, paediatric, IOL, children and amblyopia alone or in various combinations y...

By Maria Clara Arbelaez, MD Hyperopia-correcting laser surgery can be broadly categorized into intrastromal and surface ablation techniques. Of intrastromal approaches, LASIK is the most popular for the correction of hyperopia. In surface treatments such as PRK, LASEK, and transepithelial PRK, mitomycin C is applied in the majority of cases. Due to differences in epithelial healing, a transepit...

PURPOSE To determine the effect of dilute alcohol on human corneal epithelial cellular morphology and viability. Dilute alcohol is used for epithelial removal during photorefractive keratectomy (PRK) and laser subepithelial keratomileusis (LASEK). METHODS Corneal epithelial sheets harvested from human eyes after alcohol application during PRK were examined by light and electron microscopy (sp...

N "EURONAL cells have a complex morphology, extending most of their cytoplasm over long distances in the form of axons. The protein synthetic machinery is excluded from the axon, making the axon dependent upon the cell body for the tremendous levels of proteins required for its growth (Lasek and Brady, 1981). As a result, axon growth requires an efficient and sophisticated machinery to transpor...

brownal @ ohiouedu 380 Slow axonal transport: the polymer transport model About 20 years ago, Lasek and colleagues proposed that cytoskeletal proteins are transported along axons as assembled polymers, and cytosolic proteins are transported coordinately by association with these polymers. Over the years, this hypothesis has met with repeated challenges from workers who favour a model in which c...

Laser in-situ keratomileusis (LASIK) is a widely performed refractive surgical procedure that provides excellent visual outcomes. Creation of the flap and stromal ablation disrupt corneal integrity and alter its function. Damaged epithelial cells release cytokines and growth factors that interact with stromal keratocytes to trigger the regeneration process. However, these interactions under the...
