Computer-Aided Decision System for Refractive surgeries with excimer laser

124 patients (248 eyes) who intended to refractive surgery by Excimer laser were studied to implement our goal of this study which is design and operate a computer-aided decision system for optimal choosing the best refractive surgery based on patient needs, Starting from corneal topography and aberration images, using RGB and HSI color spaces and decision tree. The system also can calculate pe...

Comparison of different femtosecond laser refractive surgeries on higher-order aberrations

This study aimed to investigate the effects of femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) on higher-order aberrations in patients. 56 cases (112 eyes) undergoing refractive surgery in our hospital were selected in this study, all patients were randomly divided into femtosecond laser-assisted in situ keratomileusis group (LASIK gr...

Surgically induced corneal refractive change following glaucoma surgery: nonpenetrating trabecular surgeries versus trabeculectomy.

PURPOSE To compare surgically induced corneal refractive change following trabeculectomy with the nonpenetrating trabecular filtering surgeries with and without implant. SETTING Department of Ophthalmology, Ege University School of Medicine, Izmir, Turkey. METHODS A consecutive series of 34 patients (34 eyes) with uncontrolled open-angle glaucoma had trabecular filtering surgery. Patients w...
