In vitro human corneal model to investigate stromal epithelial interactions following refractive surgery.

Purpose: To develop an in vitro human corneal model to evaluate stromal epithelial interactions following corneal refractive surgical procedures.

Setting: Department of Academic Ophthalmology, Rayne Institute, St. Thomas' Hospital, London, United Kingdom.

Effect of exogenous keratinocyte growth factor on corneal epithelial migration after photorefractive keratectomy.

Purpose: To investigate the effect of topical keratinocyte growth factor (KGF) on wound healing after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK).

Setting: Department of Ophthalmology, Rayne Institute, St. Thomas' Hospital, London, United Kingdom, St.

Persistent haze and disorganization of anterior stromal collagen appear unrelated following phototherapeutic keratectomy.

Purpose: The theoretical effects on corneal transparency induced by changes in collagen fibril packing following phototherapeutic keratectomy were compared to changes in objective measurements of haze.

Methods: Phototherapeutic keratectomy was performed on the right eyes of four young rabbits; left eyes were used as controls. Postoperative slit-lamp measurements of haze were taken at regular intervals up to 19 months.
