Abstract
To investigate the physiological retinal response to uneventful cataract surgery using conventional time-domain (TD-OCT) and current spectral-domain optical coherence tomography (SD-OCT) in combination with an assessment of the anterior chamber inflammatory reaction by laser flare/cell meter (LCFM). Thirty-four patients scheduled for cataract surgery were included in this prospective pilot study. Retinal parameters were examined according to a standardized examination procedure using TD-OCT (Stratus; Carl Zeiss Meditec, Dublin, California, USA) and SD-OCT (Cirrus; Carl Zeiss Meditec) devices. The inflammatory reaction of the anterior chamber was measured by LFCM (Kowa FC-1000, Kowa Co. Ltd, Tokyo, Japan). Examinations were carried out preoperatively and at day 2, week 1 and week 4 postoperatively. A slight decrease of central retinal thickness values was identified at day 2 postoperatively followed by an increase of these parameters at week 4. LFCM showed peak values in all patients at day 2 postoperatively with a constant decrease at the following visits. No visible pathological retinal changes were seen after surgery. A biphasic retinal response after surgery could be shown with SD-OCT and TD-OCT technology. By using the advantages of rasterscanning mode, SD-OCT technology is superior to TD-OCT imaging in the investigation of the physiological retinal response to cataract surgery.
