ABSTRACT Objective: To characterize the morphological aspects related to the integrity of the corneas. Methods: A biomicroscopic analysis of the corneas collected from January 2019 to January 2021, by the Human Eye Tissue Bank of Hospital João XXIII, in order to identify the main changes that led to their discarding, based on the medical records analyzed. Results: Almost all variables coincided with what the literature indicates; however, stromal infiltration manifested differently. Conclusion: The main discarding factors were epithelial exposure, epithelial […]

OBJECTIVE: To evaluate the knowledge base of Pontifical Catholic University of Campinas medical students regarding ophthalmic emergencies (OE). METHODS: Cross-sectional survey among first-year and sixth-year medical students based on data collection obtained through a standardized questionnaire containing a self-evaluation test in which the students had to evaluate their knowledge into “good”, “average” or “insufficient”, and 10 multiple choice questions covering the OE themes. The data were evaluated using measures of central tendency and Student’s T test for assessing the continous […]

PURPOSE: To evaluate the Piaui Federal University graduating medical students’ knowledge in basic ophthalmology, in order to promote curricular changes in this course. METHODS: Students that had already passed the ophthalmology course were asked to answer a standard questionnaire containing 10 multiple choice questions about some ophthalmology topics considered important in the general Doctor’s graduation, such as blinding prevention and ophthalmic emergencies. The students were also asked if they would feel secure and comfortable if they had to manage an […]

PURPOSE: To evaluate distance, intermediate, and near vision after aspheric multifocal diffractive AcrySof® ReSTOR® SN6AD1 intraocular lens (IOL) implantation. METHODS: Prospective study of 50 patients with cataract that had phacoemulsification and AcrySof® ReSTOR® IOL implantation. Uncorrected distance vision acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and distance-corrected intermediate visual acuity (DCIVA) were measured postoperatively. A patient-satisfaction and visual phenomena questionnaire was administered at the end of the study. RESULTS: Three months postoperatively, the mean acuities […]

PURPOSE: To analyze causes of discarded donor corneas which were collected and preserved by São Paulo Hospital Eye Bank in a period of two years. METHODS: Retrospective study based in the investigation of donor’s medical records, for clinical and ocular factors, age, death cause, serology results, body conditions, slit lamp corneal examination and endothelial cells counting. RESULTS: 1,116 corneas were donated and included in the study, 518 (46.41%) were discarded before preservation, 168 (15.05%) were not transplanted for optical purpose, […]

PURPOSE: There are several methods to measure the Interpupilary Distance (IPD), but the method used in most office is the milimetric ruler. Currently, the autorrefractor is used routinely to find for the subjective evaluation of the refractive error, but the IPD from the autorrefractor is often not compared with the traditional method of measurement.The objective of the study is to achieve the measures of IPD between the two methods and compare the results with each other. METHODS: One hundred and […]
