ABSTRACT Purpose: To evaluate the visual, topographic, and refractive outcomes of the implantation of asymmetric segments (AS) of the ICRS intracorneal ring in eyes with keratoconus and irregular/asymmetric astigmatism (phenotypes type 2 Duck and 3 Snowman by morphological classification of Fernandez-Vega/Alfonso Keratoconus). Methods: Prospective clinical study including 60 patients (60 eyes) with keratoconus who underwent implantation of the Kearing ICRS selected and implanted according to the Mediphacos nomogram () with femtosecond laser. Preoperative and postoperative evaluations included uncorrected visual acuity, […]

ABSTRACT Objective: To outline the epidemiological profile of a reference ophthalmological emergency department, with no appointment scheduled, at a tertiary hospital in Southern Brazil. Methods: A cross-sectional historical study was conducted at Hospital Regional de São José, Santa Catarina, covering all visits to the ophthalmological emergency department over 46 days in 2019 (n = 1,728). Data were entered in a spreadsheet and analyzed using Statistical Package for Social Sciences, version 21.0.0.0), with frequencies and chi-square tests for categorical data (p […]

ABSTRACT Objective: To evaluate patients’ clinical-epidemiological profile and causative agents of infectious keratitis on patients submitted to culture obtained from corneal smears in an ophthalmological emergency in a reference hospital. Methods: Retrospective analysis of medical records and corneal culture examination results. The data were collected after the approval of the Human Research Ethics Committee. Results: Most patients were male, with an average age of 47.6 years old, Caucasian ethnicity, low level of education, and from the Greater Florianópolis area. Ocular […]

ABSTRACT Objective: To assess the impact of the COVID-19 pandemic on corneal donations and the operation of the eye bank in the Zona da Mata Mineira Region. Methods: Retrospective analysis of medical records of all donations obtained by the Banco de Olhos Hospital Regional Dr. João Penido/FHEMIG, Juiz de Fora – MG between 2017 and 2022, comparing pre (January/2017 – March 11/2020) and post-pandemic (12/March/2020 – December/2022) periods. Results: There was a reduction in cornea donations and the number of […]

ABSTRACT Objective To evaluate intraocular lens power calculation and postoperative refractive errors in patients with high myopia undergoing cataract surgery, comparing predicted target refraction and actual postoperative refraction measured 30 days after surgery with SRK/T formula. Methods This retrospective analysis comprised 39 eyes of 31 patients undergoing cataract surgery through phacoemulsification with in-the-bag IOL implantation. Axial length was measured by partial coherence interferometry or immersion ultrasound biometry, with measurements greater than 26 mm and preoperative myopia greater than -6.0 D […]

ABSTRACT Objective: To evaluate the long-term safety and efficacy of repeated corneal cross-linking in eyes of children and adolescents with progressive keratoconus. Methods: This retrospective study included nine eyes of nine consecutive patients with progressive keratoconus who underwent repeated corneal cross-linking 3.9 (range of 1.6 to 5.6) years after a primary one. All patients were followed for a mean period of 9.11 (range of 6 to 11) years after first treatment and 5.44 (range of 4 to 9) years, after […]

ABSTRACT Objective: To verify whether there are pathological dysfunctions in the cornea of patients with endometriosis. Methods: Case-control research with a quantitative approach that compared topographic and tomographic examinations of the cornea of patients with a laparoscopic diagnosis of endometriosis, without the use of hormonal medications, to the control group. Results: We analyzed 78 eyes, 34 from the endometriosis group and 44 from the control group. The loss of orthogonality between the axes of the corneal curvatures was more frequent […]

ABSTRACT Objective: To characterize the effectiveness of anti-vascular endothelial growth factor drugs in exudative age-related macular degeneration. Methods: Retrospective longitudinal study of 54 patients with age-related macular degeneration receiving bevacizumab or aflibercept. Demographic data, visual acuity, and central retinal thickness measurements were collected. Improvement/stability of visual acuity and reduction in retinal thickness configured satisfactory responses. Results: Among the 60 eyes studied, there was no difference (p = 0.262) in satisfactory response when using bevacizumab (48.5%) or aflibercept (63.0%). Snellen’s visual […]
