Read moreBackground Type 1 lattice corneal dystrophy (LCD1) is a rare hereditary bilateral disorder of the cornea. This is a result of an autosomal dominant mutation of the TGFBI (transforming growth factor beta induced) gene which leads to accumulation of amyloid deposits in stroma1 Variable clinical appearance depends on the...
Read moreToday, it is well understood that knowledge of the sagittal height of the anterior eye is a key component in the fitting of both custom soft contact lenses and modern scleral lens designs. Our studies at Pacific University have identified five anatomical features that contribute to the sagittal height...
Read moreIntroduction Traditionally, gas permeable, scleral and even hybrid contact lenses are recommended for patients with keratoconus or other diseases that cause irregularity of the cornea, as they can effectively correct the significant levels of astigmatism through neutralization by the tear film. However, there is evidence to support the use...
