Scleral contact lenses for visual rehabilitation after penetrating keratoplasty: long term outcomes.
PURPOSE To evaluate the success rate of highly gas permeable scleral contact lenses (SCL) for visual rehabilitation after penetrating keratoplasty (PK), over a period of up to 9 years. METHODS A total database of 31 consecutive patient fitted with SCL between January 2004 and December 2009 was retrospectively reviewed. Demographic data, etiology prior to lens fitting, visual outcomes, follow ...
متن کاملContact lenses and special back surface design after penetrating keratoplasty to improve contact lens fit and visual outcome.
AIMS To describe the fitting of patients with high or irregular astigmatism following penetrating keratoplasty with contact lenses and to answer the question whether or not contact lenses with special back surface design can improve visual acuity in complex cases after penetrating keratoplasty. METHODS 28 eyes were included. They were fitted with contact lenses with a special back surface tha...
متن کاملVisual performance with simultaneous vision multifocal contact lenses.
PURPOSE The aim was to assess visual performance after PureVision high addition multifocal contact lens (PM) fitting through contrast sensitivity measured under different illumination levels for both distance and near. METHODS In a cross-over study, 20 presbyopic patients were randomly assigned to PM or spectacles. Near contrast sensitivity was measured with the Vistech VCTS 6500 system. ...
متن کاملPredicting and assessing visual performance with multizone bifocal contact lenses.
PURPOSE To investigate how bifocal contact lenses, when combined with the aberrations of the eye, will affect visual performance. Also, to investigate the relationship between the patient's predicted and actual visual benefit with bifocal contact lenses. METHODS The monochromatic aberrations of 16 subjects were measured and used to simulate visual quality with three bifocal contact lens desig...
متن کاملContact Lens Visual Rehabilitation in Keratoconus and Corneal Keratoplasty
Keratoconus is the most common corneal distrophy. It's a noninflammatory progressive thinning process that leads to conical ectasia of the cornea, causing high myopia and astigmatism. Many treatment choices include spectacle correction and contact lens wear, collagen cross linking, intracorneal ring segments implantation and finally keratoplasty. Contact lenses are commonly used to reduce astig...
