ABSTRACT This case report presents a patient who underwent photorefractive keratectomy 13 years after Acanthamoeba infection. The patient experienced prolonged difficulties in epithelialization during the postoperative period, leading to suspicion of reactivation. This case underscores the complexity and challenges in managing patients with a history of photorefractive keratectomy and ocular infections, particularly in cases involving Acanthamoeba. Understanding such cases is crucial for optimizing treatment strategies and achieving favorable outcomes.

ABSTRACT Objective: To know the profile of trabeculectomy, in addition to the success rate in controlling intraocular pressure in patients with glaucoma. Methods: A retrospective, observational study, with medical records of patients with glaucoma, followed up at an ophthalmological reference center, who underwent trabeculectomy from January 1, 2016 to May 31, 2017, by a single experienced surgeon. The success rate was considered with an intraocular pressure < 21 mmHg, for high intraocular pressure glaucoma, and a reduction of at least [...]

Objectives: Evaluate the effect of intraoperative endovenous administration of dipyrone on postoperative pain in patients submitted to phacoemulsification by correlating pain scores with duration of surgery and the amount of cumulative dissipated energy (CDE) delivered to the eye. Methods: The sample consisted of 104 eyes from 52 patients submitted to phacoemulsification under topic anesthesia and sedation. In each patient, one eye was treated intraoperatively with 1g dipyrone. Information was collected on cataract grade/type, duration of surgery and CDE. Postoperative pain […]

Objective: To compare the influence of two techniques for corneal epithelial removal in photorefractive keratectomy (PRK) – blunt scrape versus rotary brush – regarding duration of technique application, intraoperative comfort, and reepithelization. Methods: This prospective randomized study included 58 eyes of 29 patients that underwent simultaneous and sequential PRK in both eyes – blunt scrape (scraped group) in one eye and rotary brush (brushed group) in the fellow eye. Results: The faster technique, measured in seconds, was the rotary brush […]
