CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishPurpose: o compare the corneal tissue trauma after the use of an automated preloaded injector and a manual injector and assess scanning electron microscope (SEM) and atomic force microscope (AFM) features of both injector cartridges. SETTING: Ophthalmology Clinic and Laboratory of Stem Cells and Regenerative Medicine University "G. d'Annunzio" of Chieti-Pescara, Chieti, Italy; DESIGN: Prospective randomized clinical study METHODS: Forty eyes of 40 patients for phacoemulsification were divided into two groups: implantation of intraocular lens was performed with AutonoMe automated delivery system (AutonoMe group: 20 eyes) and Monarch III injector system (Monarch group: 20 eyes). In vivo confocal microscopy (IVCM) and anterior segment optical coherence tomography (AS-OCT) were performed before surgery, at 1 h, 1 day and 1 month post-operatively. In addition, SEM and AFM were performed on cartridges of both injector systems after injection of the IOL. RESULTS: A greater increase in central corneal thickness and corneal thickness at the incision site were observed in Monarch group versus AutonoMe group 1 h and 1 day post-operatively (p < 0.05). Endothelial cell count loss was significantly higher in Monarch group compared with AutonoMe group (p < 0.05) at 1 and 24 h. AS-OCT showed less endothelial misalignment at 30 days (p < 0.05), and IVCM showed less tunnel inflammation at all time points (p < 0.05) in AutonoMe group compared with Monarch group; roughness analysis at AFM of the AutonoMe cartridge was significantly lower compared to Monarch D cartridge (p < 0.05). CONCLUSIONS: The AutonoMe injector provided less corneal tissue trauma compared with Monarch III injector. The AutonoMe cartridge showed lower roughness at AFM compared to the Monarch D cartridge.
