ABSTRACT Throughout life, the lens produces new fibers arranged concentrically, which increase its anteroposterior diameter and weight, making its nucleus more compact and hardened. Hypermature cataract is an advanced stage of this fiber proliferation, which can trigger a variety of complications. Spontaneous rupture of the anterior lens capsule evolving with anterior displacement of the nucleus is a rare complication, with few cases published in the literature. We describe the case of a 68-year-old female patient, who presented spontaneous rupture of […]

ABSTRACT Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern […]

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 […]

Spontaneous rupture of the anterior lens capsule, evolving with anterior dislocation of the lens nucleus is a rare complication of hypermature cataract. We report a case of a female patient, 79 years old, who presented with spontaneous rupture of the anterior lens capsule with anterior dislocation of the nucleus in the right eye with no history of ocular trauma. The diagnosis was confirmed by the visualization of the tabs of the anterior capsule, especially when the nucleus was removed. We […]

PURPOSE: To correlate straylight levels, lens scattering, lens opacity and intraocular aberrometry in patients with nuclear cataract. METHODS: This is a prospective study. Thirty consecutive patients (30 eyes) were including. Ocular Straylight was evaluated using the C-Quant. Lens scattering was evaluated using Scheimpflug anterior segment tomography, using the new software PNS. Dilated slip lamp evaluation was performed and lens opacity was classified according to LOCS III scale. Total wavefront was measured by ray tracing (iTrace); intraocular aberrations were calculated by the […]

Relatamos o caso de uma senhora de 45 anos de idade, portadora de ceratocone grau 2 e consequente anisometropia, submetida à extração do cristalino transparente, e uso da lente intraocular modelo SN60T5 AcrySof Toric para o olho esquerdo. Facoemulsificação seguida pelo implante da lente intraocular tórica no olho esquerdo. No pós-operatório, resultados refracionais e visuais satisfatórios foram alcançados. O uso de lentes intraoculares tóricas pode se constituir em opção terapêutica para casos selecionados de ceratocone grau 2.

This is a case report of a 45-year-old anisometropic woman with stage 2 keratoconus submitted to refractive lens exchange employing SN60T5 AcrySof Toric intraocluar lens on her left eye. Phacoemulsification followed by proper lens implantation was accomplished successfully. On postoperative period, favorable refractive and visual outcomes were obtained. The use of toric intraocular lenses may be an option in the refractive treatment of stage 2 keratoconus in selected cases.
