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 Objective: To underscore the critical importance of assessing the peripheral retina in all patients, especially those planning to use miotics. Methods: A retrospective and observational study was conducted at a single ophthalmological medical center, using records from the International Classification of Diseases (ICD-10) for closed-angle glaucoma and lesions predisposing to detachment. Participants in this study underwent anterior chamber assessment using the Goldman 3-Mirror lens and the Volk G-4 Gonioscopy lens. Peripheral retinal evaluation was conducted with indirect binocular ophthalmoscopy […]

ABSTRACT This case series evaluates the visual outcomes of two trifocal intraocular lenses, the ZFR00V and TNFT00, in cataract surgery patients. Nineteen patients (38 eyes) were bilaterally implanted with one of the two intraocular lenses. Postoperative assessments included uncorrected and corrected distance, intermediate, and near visual acuities, as well as patient-reported satisfaction and photic phenomena. Both intraocular lenses provided satisfactory visual performance for distance and intermediate vision. However, the ZFR00V intraocular lenses demonstrated superior near vision, particularly in the defocus […]

ABSTRACT Objective: To evaluate the long-term clinical and refractive results of surgical correction of presbyopia in patients with cataracts and initial to moderate open-angle glaucoma through combined phacoemulsification surgery with multifocal intraocular lens implantation and angular surgery with trabecular implant. Methods: This is a real-world retrospective longitudinal study of a series of cases undergoing combined cataract surgery and anti-glaucoma surgery with a second-generation trabecular implant, iStent inject® (Glaukos Inc., California, USA). A statistical analysis of the entire study population was […]

ABSTRACT The term dysfunctional lens syndrome has gained acceptance in the field and encompasses natural changes due to aging of crystalline lens. The evolution of diagnostic devices has been a key factor in better staging, understanding and characterizing of these degenerative changes. Even with these technological advances and the use of subjective classifications, such as the classic Lens Opacities Classification System, an objective staging of early dysfunctional lens syndrome has yet to be established. Ocular wavefront aberrometry and objective scatter […]

Abstract Objectives: Toassess the satisfaction of patients undergoing central Presbilasik surgery and to determine the age of patients who undergo PresbiLASIK and the prevalence of symptoms reported after surgery. Methods: This is a descriptive, observational, cross-sectional study with data collected from patients previously submitted to PresbiLASIK. Results: The sample consisted of 45 patients, with a mean age of 57.7 (±7,19) years. The average score attributed to visual satisfaction with the procedure was 8.9 (±1.0). Visual quality after surgery was classified […]

Abstract Purpose: To assess long, intermediate and near uncorrected visual acuity after a tetrafocal diffractive intraocular lens implantation, presence of dystopic phenomenon and patient satisfaction after surgery. Methods: Retrospective, observational study performed in Puerta de Hierro Specialties Hospital, in Jalisco, México. That included 100 eyes after phacoemulsification surgery by femtosecond assistance, followed by tetrafocal diffractive intraocular lens implantation due to cataract. Long, intermediate and near visual acuity without correction was measured, and presence or absence of dystopic phenomenon, plus patient […]

Objective: Monovision is a concept that describes the purposely unequal correction of vision from one eye to the other and eye to eye, and is mainly used to correct presbyopia. The main objective was to evaluate patients’ satisfaction with advanced monovision refractive surgery. The secondary objectives were to evaluate the need for glasses after surgery, and to analyze the profile of the participants. Methods: A cross-sectional observational study of a series of cases was carried out based on the review […]
