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 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 […]

ABSTRACT Dry eye disease comprises a spectrum of disorders that cause unstable tear film with an irregular surface. Preexisting dry eye disease poses challenges during cataract surgery in chronic inflammation since preoperative biometry measurements are highly dependent on a smooth and healthy tear film. Following the recent approval by the Conselho Federal de Medicina, lens replacement procedures have become legal in Brazil and are indicated for patients over 55 years of age who have presbyopia with moderate or high hyperopia. […]

ABSTRACT The accuracy of the intraocular lens calculation is not perfect, and postoperative refractive errors are common, especially in patients who have undergone previous refractive surgery or in presence of asymmetric corneas. Corneal power after refractive surgery can be more accurately measured using the total optical power map in the 4-mm central zone, by means of Orbscan II or equivalent keratometric reading map available on pentacam, with central measurements of 1.0, 2.0, 3.0 and 4.5 mm. The purpose of this […]

Objective: In this review we critically evaluated the publications on the intraocular implant of the Scharioth Macular Lens (SML) in patients with advanced stages of Age-Related Macular Degeneration (AMD). Methods: The literature search was done in Pubmed and Google Scholar database, with the term dry AMD, devices and Scharioth Macula Lens. We use prospective, retrospective articles or case reports published in English or Portuguese in the last five years under these terms. Results: A total of 19 articles were found, […]

Objetivo: Descrever os resultados em termos de acuidade visual para perto e qualidade de vida em 10 pacientes submetidos ao implante de Lentes Maculares Scharioth. Local: Clínica de Olhos João Eugênio, Brasilia, Brasil. Design: Ensaio clínico não controlado. Métodos: Dez pacientes pseudofácicos com DMRI foram submetidos ao implante de SML intraocular no olho dominante no período de dezembro de 2017 a março de 2018. Todos os pacientes responderam ao Questionário de Qualidade de Vida em Baixa Visão (LVQOLQ) antes e […]

Objective: To describe the outcomes in terms of near visual acuity and quality of life in 10 patients submitted to Scharioth Macular Lens implantation. Setting: João Eugênio Eye Institute, Brasilia, Brazil. Design: Uncontroled clinical trial. Methods: Ten pseudophakic patients with DMRI were submitted to the implantation of intraocular SML in the dominant eye in the period of December of 2017 to the March of 2018. All the patients had answered the Low-Vision Quality of Life Questionaire (LVQOLQ) before and after […]

Objetivo: Avaliar os resultados pós-operatórios da utilização da LIO tórica durante a facoemulsificação. Métodos: Estudo retrospectivo tipo coorte de 95 olhos de 67 pacientes, selecionados através de censo. Foram analisados pacientes com catarata, submetidos à facoemulsificação, com colocação da LIO tórica Acrysof®, no período de janeiro de 2010 a dezembro de 2012. No entanto, foram excluídos os que realizaram outro tipo de cirurgia ou tiveram outro tipo de lente para correção da catarata e/ou prontuários incompletos. Considerou-se como sucesso o […]
