ABSTRACT This report aimed to evaluate the evolution of topography, astigmatism, and visual acuity in eyes with keratoconus that underwent intra-stromal ring implant surgery. The report compared these results with those of contralateral, non-operated eyes. The goal was to confirm whether the intra-stromal ring implant surgery could also slow the progression of the disease. Four cases of young and adult patients who underwent corneal ring implant surgery in one eye were analyzed, with clinical and topographic follow-up for up to […]

ABSTRACT Objective: To develop and validate a smartphone application capable of magnifying near images and, through educational videos, informing users about presbyopia. Methods: This was a cross-sectional, quantitative study conducted by a multidisciplinary team of ophthalmologists and software engineers. The development and validation of the application, named PRESB, occurred in three main stages. First, the user interface and native functions were designed. Second, the application was tested by patients who had undergone bilateral age-related cataract surgery with implantation of a […]

ABSTRACT Acute corneal hydrops is an ophthalmologic emergency resulting from rupture of Descemet’s membrane with entry of aqueous humor into the corneal stroma. Patients typically present with ocular pain, blurred vision, photophobia, and tearing. The main risk factors include trauma due to ocular itching, allergic keratoconjunctivitis, corneal ectasia, and Down syndrome. Although a rare complication, it is most commonly associated with keratoconus. Clinical treatment with eye drops should always be initiated, but in advanced cases, combined surgical intervention may be […]

ABSTRACT This systematic review and meta-analysis compared Manual Small Incision Cataract Surgery (MSICS) with phacoemulsification for the management of mature cataracts, evaluating outcomes such as visual acuity, surgical complications, endothelial cell loss, central corneal thickness, surgery duration, and cost-effectiveness. A comprehensive search was conducted across PubMed®, Web of Science, Embase, and the Cochrane Library through November 23, 2023, without language restrictions. Of 163 articles initially retrieved, five studies met the inclusion criteria, encompassing a total of 577 eyes. Pooled results […]

ABSTRACT Objective: To analyze how inappropriate pharmacotherapy use influences glaucoma progression in patients from Paraíba’s hinterlands. Methods: A field-based, quantitative, cross-sectional study was conducted at the Frei Damião Specialty Center in Patos (PB), with 104 participants diagnosed with glaucoma. Patients unable to respond or who did not attend the appointments in the past 12 months were excluded. Data collection was conducted in person using three questionnaires: one on clinical and socioeconomic variables and two using the Morisky scale to assess […]

ABSTRACT This case series presents the shamrock sign, a novel aberrometry pattern characterized by trefoil and coma, as a potential diagnostic marker for nuclear cataracts associated with myopic shift. This study highlights its clinical relevance and contribution to early detection and management. The primary diagnosis was nuclear cataracts inducing myopic shift. All patients underwent phacoemulsification with intraocular lens implantation. Postoperatively, all cases showed marked reductions in higher-order aberrations, including spherical aberration and trefoil, with complete resolution of the shamrock sign. […]

ABSTRACT Objective: To analyze visual performance in digitally active volunteers using ScCLs. Methods: ScCLs were fit in seven participants and evaluated during four visits over 45 consecutive days. Reading speed tests were performed with MNREAD-P charts and texts developed by the Department of Speech Therapy of the authors’ institution. Post-study, participants were interviewed and completed the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8). Results: During ScCL wear, 85.7% showed increased reading speed on MNREAD-P charts, with similar results on the […]

ABSTRACT Objective: This study aimed to validate the psychometric properties, feasibility, and clinical utility of the Tumbling-Hand test. Methods: The validation process involved two phases. In neurotypical participants, VA thresholds of the Tumbling-Hand test were compared with the printed Tumbling E test, with repeatability assessed using intraclass correlation coefficients (ICCs) and Bland-Altman analysis. In neurodivergent participants, the feasibility and success rates of the Tumbling-Hand test were evaluated against the Tumbling E and Landolt C tests. Statistical analyses, including McNamar’s and […]
