The benefits of Nd:YAG laser capsulotomy on visual performance were evaluated in 13 patients with after-cataract following extracapsular cataract extraction. Besides clinical evaluation we measured: visual acuity, letter contrast sensitivity with and without the presence of a circular glare source (glare angle: 8 degrees). Finally, the patients were asked to evaluate their subjective glare prob...

BACKGROUND The aim of this study was to evaluate the impact of capsulorhexis diameter, localization and shape on posterior capsule opacification (PCO) development after cataract extraction with phacoemulsification. MATERIAL/METHODS We retrospectively analyzed of 297 patients who underwent phacoemulsification and AcrySof SA60AT implantation. In a first group of 97 patients, 53 received small c...

AIM To assess and compare the results of primary and secondary implantation of scleral fixated posterior chamber intraocular lens (SFIOL). METHODS The medical records of a consecutive series of 55 eyes of 55 patients with SFIOLs implanted during (group 1) or after (group 2) complicated senile cataract surgery were retrospectively reviewed and analysed. RESULTS There were 30 and 25 eyes in g...

A total of 80 patients with senile cataract had the anterior eye chamber depth measured optically by means of Haag-Streit's attachment II. The distance to the pupillary border was 2.59 +/- 0.05 mm (mean +/- SEM) preoperatively. It increased gradually after cataract extraction to 3.33 +/- 0.04 mm, measured 4 months after the operation. The increase of depth was the greatest in patients with a fl...

Cataract is a significant cause of visual disability in the pediatric population worldwide and can significantly impact the neurobiological development of a child. Early diagnosis and prompt surgical intervention is critical to prevent irreversible amblyopia. Thorough ocular evaluation, including the onset, duration, and morphology of a cataract, is essential to determine the timing for surgica...

TREACHER COLLINS (1917), in his classical article on the sequelae of persistent hypotony, stated that the pathological changes in the ocular tissues were " brought about either from the relaxation of tissues usually kept taut or from altered conditions in the circulation ". Subsequent reports have only confirmed the accuracy of these observations. Within recent years the physiology of hypotony,...

Introduction: Synaptosomes are sealed particles that contain mitochondria, cytoskeleton and vesicles which are necessary to synaptic events like neurotransmitter release and uptake in the nervous system. However, the effect of high and low temperatures on synaptosome membrane integrity and function during a time course after its extraction is less known. The purpose of this study was to assess ...
