DGII 2003: Refractive Surgery – Update

Kohnen T.
Johann-Wolfgang-Goethe-Universität, Klinik für Augenheilkunde, Frankfurt/Main

The primary procedure in refractive surgery has become laser-in-situ keratomileusis (LASIK). Possible complications of this procedure are being examined carefully, because they may have a dramatic effect on the visual function of the patient. Examinations include a detailed report on intraoperative complications as well as long-term follow-up of the surgeries. With wavefront-guided excimer ablation, the optical quality of vision can be improved. In Germany, excimer laser subepithelial ablation (LASEK) has been used more frequently. Now 1-year results are available for this procedure. For those excimer laser treatments, which meet the standard expectations for corneal refractive surgery, it is important to be and to remain predictable, safe, efficient and stable and to investigate the complications. In order to further reduce the complication rate in refractive surgery, diagnostic instruments are modified and improved. For example, online pachymetry, lamellar corneal cuts by femto-second laser technology or topographical and wavefront analysis by modern systems. Next to corneal refractive surgery, intraocular refractive surgery, like phakic intraocular lens implantation and refractive lens exchange are performed. For refractive lens exchange modified design such as potential accommodative, multifocal or bifocal or aspheric IOLs are investigated. For phakic intraocular lens implantation, there are follow-ups available for more than one year on angle-supported anterior
