title: [Laser and corneal surgery: topography and preoperative evaluation].
abstract: The purpose of preoperative clinical examination is to determine accurately the refraction under cycloplegia. Operative techniques and protocols are chosen in relation to the degree of ametropia. Computer assisted videokeratography allows early keratoconus detection and gives reference quantitative datas for analysing postoperative changes.
