Purpose: To evaluate the contrast sensitivity and stereopsis tests in patients who underwent bilateral implantation of multifocal intraocular lens.
Methods: Tests of contrast sensitivity using the Pelli-Robson chart and stereopsis evaluation with the Titmus Stereo Test were performed in 20 patients 30-60 days after the bilateral implantation of Acrysof Restor multifocal intraocular lens.
Results: The binocular contrast sensitivity test demonstrated that 6 patients (30%) presented 1.80 log units, 13 (65%) 1.65 and in only 1 (5%) the sensitivity was 1.50 log units. By the other hand, the monocular test in right eye showed 17 patients (85%) with 1.65 log units and 3 (15%) with 1.50. In the left eye, the test presented 16 patients (80%) with 1.65 log units and 4 (20%) with 1.50 log units. The average and the standard deviation of the contrast sensitivity were 1.63 (+/-0.05) for right eye, 1.62 (+/-0.06) for left eye and 1.69 (+/-0.08) for binocular test. Stereopsis test disclosed 12 patients (60%) presenting 40", 6 (30%) 50" and only 2 (10%) 60" (average: 45" and standard deviation: 6.88").
Conclusions: The Acrysof Restor intraocular lens provided results of contrast sensitivity and stereopsis in accordance with the criteria of normality established previously in other studies for phakic and pseudophakic patients. Therefore, this intraocular lens does not decrease visual functionality.

Contrast-enhanced mammography (CEM) is growing in clinical use due to its increased sensitivity and specificity compared to full-field digital mammography (FFDM) and/or digital breast tomosynthesis (DBT), particularly in patients with dense breasts. To perform an intraindividual comparison of MGD between FFDM, DBT, a combination protocol using both FFDM and DBT (combined FFDM-DBT), and CEM, in patients undergoing breast cancer screening. This retrospective study included 389 women (median age, 57.

Background: Although optic neuritis (ON) is common in multiple sclerosis (MS), lesions of the optic nerve are not included as an anatomical substrate for dissemination in space and time (DIS and DIT).
Objective: To assess the increase in sensitivity of including MRI lesions of the optic nerve for the diagnosis of MS in patients with ON.
Methods: We included patients consecutively referred with first time, monosymptomatic ON, with no known cause of the ON, who underwent orbital MRI including fat suppressed T2 and T1-sequences with and without gadolinium contrast.

Unlabelled: This study aims to determine the incidence, clinical course, and risk factors of hypothyroidism following cardiac catheter (CC) in infants with congenital heart diseases (CHD). This prospective study involved 115 patients with CHD, all aged 3 years or younger, who underwent CC, as well as 100 healthy age- and sex-matched controls. Baseline thyroid function tests (TFTs) were conducted for both the patients and controls.

Background: Dosimetric commissioning and quality assurance (QA) for linear accelerators (LINACs) present a significant challenge for clinical physicists due to the high measurement workload and stringent precision standards. This challenge is exacerbated for radiosurgery LINACs because of increased measurement uncertainty and more demanding setup accuracy for small-field beams. Optimizing physicists' effort during beam measurements while ensuring the quality of the measured data is crucial for clinical efficiency and patient safety.
