Pseudoexfoliation, one of the most frequent crystalline lens complex disorders, is prevalent in up to 30% of individuals older than 60 years old. This disease can lead to severe conditions, such as subluxation or dislocation of the lens, due to the weakening of the zonules. The goal for the present study was to understand the relevant biomechanical...

Cataract is a disease opacifying the crystalline, leading to a blurred vision and ultimately to blindness. With an aging population, the incidence of cataract is increasing, as well as the number of treatments. The solution available is its complete removal, followed by an implant of an intraocular lens (IOL). Although the post-operative complicati...

Overview of current methodologies for intraocular lens power calculation.

RESUMO Objetivos: Comparar o erro refrativo subjetivo determinado por quatro métodos de cálculo de lentes intra-oculares (LIO)-fórmulas SRK-T, Barrett, PhacoOptics e Radial Basis Functions (RBF)-com o equivalente esférico subjetivo residual. Comparar a potência da LIO obtida numa pseudo-população Montecarlo com combinações infrequentes de parâmetro...

RESUMO Objectivos: Os relatos de luxações tardias espontâneas, parciais ou totais, do complexo saco capsular-lente intra-ocular (LIO) têm vindo a aumentar. Esta complicação é reportada em média 6.9-10.9 anos após a cirurgia de catarata, em doentes com idades médias entre 71-80 anos. A crescente exigência visual da população, que tem conduzido ao im...

We report a case of a 65-year-old woman with symptoms of blurred vision and ocular irritation a few hours after accidental contact of the right eye with Asclepias physocarpa milky latex. Observation showed a diffuse conjunctival hyperemia and stromal corneal edema with Descemet's membrane folds. Recovery was fast and apparently complete in less tha...

The authors report the case of a child with horizontal gaze palsy with progressive scoliosis and keratoconus. ROBO3 analysis identified compound heterozygous mutations. Keratoconus surgical approach resulted in visual acuity improvement in both eyes. The previously unreported occurrence of keratoconus with horizontal gaze palsy with progressive sco...
