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 […]

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 This review discusses various surgical techniques for correcting aphakia in patients without adequate capsular support, focusing on lens implantation methods and their associated outcomes. It evaluates anterior chamber intraocular lenses, iris fixation with or without sutures, and scleral fixation techniques, both sutured and sutureless. Each method is assessed for its visual acuity results, complication rates, and long-term stability. The advantages and disadvantages of iris and scleral fixation are compared, addressing risks such as endothelial loss, intraocular lens dislocation, and […]
