ABSTRACT Objective: To evaluate refractive and topographic outcomes before and at least 7 years after intrastromal ring segment implantation surgery in patients with keratoconus. Methods: Long-term retrospective longitudinal study carried out with 35 patients (62 eyes) aged 10 to 30 who underwent intrastromal ring segment implantation using a manual technique. Different arc rings were analyzed across various keratoconus types. Results: Significant improvements in topographic astigmatism (p = 0.001) and corrected distance visual acuity (p < 0.001) were observed, with no [...]

ABSTRACT Objective: To evaluate the effect of pterygium on different biometric intraocular lens calculation formulas. Methods: This is an interventionist, prospective, and non-randomized study. We included patients who underwent pterygium surgery and performed a biometric examination before and one month after surgery. We compared the mean variability between these measurements in each intraocular lens formula. We classified the patients according to the TAN staging system and evaluated the effect of pterygium magnitude on biometric variability. Results: We included 25 eyes […]

ABSTRACT Objective: To describe the epidemiological profile of corneal disorders diagnosed in the Corneal Department of the Ophthalmology Reference Center, Universidade Federal de Goiás, between 2009 and 2018. Methods: A descriptive, retrospective, cross-sectional study was performed by reviewing of the patients’ medical record. The data collected were registered according to sex, age, and diagnosed eye disorder. The need for corneal transplantation was also assessed. Results: The charts of 3,079 patients were analyzed, of which 52.7% were men. In the sample […]

ABSTRACT Objective: To evaluate the clinical and surgical results of patients undergoing corneal endothelial transplant surgery. Methods: Retrospective study in which medical records were reviewed from May 2016 to May 2023, to evaluate transplant indications, intra- and postoperative complications and survival of the graft. Results: Seventeen patients were included, 12 (70.6%) were female and the average age was 70.18. The main indication for corneal endothelial transplant surgery was pseudophakic bullous keratopathy (64.7%), followed by Fuchs dystrophy (23.5%). Regarding postoperative visual […]

ABSTRACT Objective: To develop and validate a Children’s Eye Care Guide for Ophthalmology courses. Methods: Methodological study on the development and validation of teaching material using the ADDIE instructional design. The validation phase used a panel of experts and an Educational Content Validation Instrument in Health to evaluate the content, and residents for semantic evaluation. Results: A Guide for children’s ophthalmological care was developed and validated, covering the topics of eye testing and stages of the ophthalmological examination: anamnesis, visual […]

ABSTRACT Objective: To evaluate the efficacy of high-dose oral riboflavin treatment combined with sun exposure in preventing the progression of keratoconus. Methods: A retrospective, multicenter observational study involving 53 keratoconus patients (106 eyes) from three Brazilian cities. Patients were instructed to take 400 mg/day of oral riboflavin and to sunbathe for 30 minutes daily, in addition to avoiding eye rubbing. Keratometric measurements were evaluated before and after 6, 12, 24, and 36 months of treatment. Results: After 6 months, 42 […]
