Perceptual learning to reduce crowding in visually impaired children: 'Learning to see the forest ánd the trees'

The main goal of this study is to investigate whether visual perceptual learning, i.e. practicing a challenging visual task and thereby improving performance, transfers to improved reading and search performance in children with visual impairment.…

Partial endothelial trepanation in addition to deep anterior lamellar keratoplasty in keratoconus patients. A randomized clinical trial.

To investigate the additional value of partial endothelial trepanation (PET) in a deep anterior lamellar keratoplasty (DALK) procedure in terms of efficacy and safety in patients with keratoconus.

Screening for problems in eyes of children study (SPECS)

The aim of this study is to compare the results of 2 methods for screening of eye function in children with the standard investigation by the orthoptist. The outcome of the tests and the time involved will be compared.Two screening methods will be…

Long-term effects of the crowding training and transfer to untrained tasks

• Determine to which extent near visual acuity and crowding improvements are retained at 6 and 12 months after training • Determine transfer of training effects to untrained tasks, in this case reading and fine motor performance.
