Abstract Objective: Develop a training model for corneal surgery using grapes. Methods: Grapes were used as structures that mimic the size of the human eyeball, covered with latex materials, simulating the practice of corneal surgery using a videomagnification system. Eight simple stitches were performed. The surgical time was evaluated. Results: 25 simulations were carried out as the model described. The mean time taken for the raffia was 34.56 ± 5.79 minutes. The analysis of the correlation between the time and […]

Abstract Objective: To describe the epidemiological profile of patients submitted to corneal transplantation in state of Espirito Santo, Brazil. Methods: Transversal and descriptive study, with 1301 patients, in the period of January 2017 until to January 2018, the patients were registered in the Central Notification, Captation and Distribution of Organs of Espirito Santo (CNCDO/ES) through the National Transplant System (SNT) and submitted to corneal transplantation. The data were shown as descriptive statistics (frequencies and medians) and analysis of the data […]

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 […]

Abstract Purpose: To evaluate six different premium IOLs retrospectively in respect to both subjective and objective refraction after cataract operation. Methods: Five hundreds and seventy eyes of 285 patients with bilateral cataract who had undergone phacoemulsification and IOL implantation operation between February 2017 and September 2018 were enrolled in this study. The mean age of the patients was 57.78 ± 7.49 (41-71) years. Out of 285 patients 137 were male (48.07%) and 148 were female (51.93%). TheIOLsusedare: RayOne Trifocal (Rayner, […]

Abstract Background: The visual screening performed in schools is sometimes the only opportunity to detect uncorrected refraction errors (URE) causing low visual impairments, prejudice in the acquisition of knowledge, dropout and school repetition, poor motor skills, difficulty in social interaction and low self-esteem in schoolchildren. Objectives: To compare the detection of URE in elementary school children by visual screening (measurement of the AV with the Snellen table) and photoscreening; to evaluate the accuracy of the SpotTM Vision Screener (Welch Allyn) […]

Abstract Objective: Observe the agreement between IOL Master 500 and Pentacam AXL and describe the averages. Methods: We analyzed 35 medical records, totaling 61 eyes. All patients underwent biometric evaluation on both devices from August 2018 to August 2019. The data collected were: age, gender, anterior chamber depth, axial length, K1, K2, biometrics and IOL target. Results: The averages of the variables analyzed between the optical biometric devices in question had a statistically significant difference (p

Abstract This paper provides a fast and inexpensive technique to prevent slippage of the infusion cannula from the EVA DORC® 27-gauge system. After the usual retrobulbar anesthesia, antisepsis and asepsis, a 2% hydroxypropyl methylcellulose drop is placed around the infusion cannula in the trocar to hold it in position. This technique prevents the slippage of the infusion cannula and both the surgical time and creation of the first sclerotomy in the eye can be shortened slightly.

Abstract Objective: analyzing the influence of schooling and kinship on families’ decision to donate corneas for transplants. Method: quantitative, cross-sectional and retrospective study whose sample comprised 291 records of interviews conducted with family members of potential corneal donors from January 2015 to December 2017, who were treated in a public, general and large-sized hospital in Porto Alegre City, Rio Grande do Sul State, Brazil. Results: 53.3% of the potential corneal donors were male at mean age of 57 years (57 […]
