UNLABELLED The study shows a promising next-generation surgical option for the correction of moderate to high ametropia. Hole implantable collamer lens (ICL), STAAR Surgical, is a posterior chamber phakic intraocular lens with a central artificial hole. As yet, however, no long-term comparison of the clinical results of the implantation of ICLs with and without such a hole has hitherto been con...

AIMS To evaluate the relation between refractive error and electrophysiological retinal abnormalities in children referred for investigation of reduced vision. METHODS The study group comprised 123 consecutive patients referred over a 14 month period from the paediatric service of Moorfields Eye Hospital for electrophysiological investigation of reduced vision. Subjects were divided into five...

Measurement of visual acuity remains the most frequently used technique for the assessment of vision in both adults and children. Visual acuity is usually measured clinically in adults using a Snellen chart. However. this technique demands a level of cognition and literacy which is beyond the majority of young children. The measurement of visual acuity in preschool children presents an addition...

In the presence of the media opacities and extreme ametropia, especially in high myopia, often arises a question of expected visual acuity, e.g. after cataract extraction because of the possible degenerative changes of the choroid and retina. In the measurements were enrolled 15 patients between 45 and 60 years of age, 9 female and 6 male. We have tested preoperative retinal visual acuity by th...

High myopia is a common ametropia associated with significant risk of multiple comorbidities. Decreased visual functions myopic patients may be caused by non-specific diseases such as cataracts, glaucoma and rhegmatogenous retinal detachment, which are very likely in myopia. Yet especially important the specific changes atrophic, traction neovascular manifestations pathological myopia, totality...
