ABSTRACT Objective: To evaluate the agreement between the Eyestar900 and IOLMaster700 for biometric measurements and assess their interchangeability. Methods: This retrospective study analyzed the following parameters: anterior keratometry, axial length, anterior chamber depth, white-to-white diameter, and lens thickness. Agreement was assessed using intraclass correlation coefficients, Bland-Altman plots, and scatter plots. A paired t-test was used to evaluate statistical differences. Results: A total of 43 eyes from 33 patients were analyzed. The mean differences were 0.03 D for keratometry, 0.08 mm […]

Abstract Objective: To compare the use of 2 different local anesthetic solution (LAS) volumes of 1.5 mL and 3 mL in retrobulbar block in patients undergoing cataract surgery in terms of anesthesia, akinesia, and pain levels. Methods: 80 patients between 18-90 years old, ASA I-II-III, were included in the study. For retrobulbar anesthesia, 1.5 mL LAS was applied to one group (Group LV), and 3 mL LAS to the other group (Group HV). The patients’ ocular and eyelid motion scores […]

We here in report the case of a patient subjected to cataract surgery through phacoemulsification under local anesthetic block, without intra-operative complications. The patient presented important visual impairment in the first post-operative day. Fundoscopy showed pallor resembling cherry-red spots at the macula. Fluorescein angiography did not depict signs of vascular occlusion and the spectral-domain optical coherence tomography showed increased reflectivity in the inner layers of the retina, thus suggesting local thickening and edema. The current case led to the diagnostic […]

Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge), the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract […]
