Keratoconus: Diagnosis, contact lens fitting and management

Estimates lie between 50 and 230 per 100,000 in the general population, approximately one per 2000.2,7,8 When considering the prevalence of keratoconus the differing diagnostic criteria used in different studies need to be taken into account. A much higher prevalence may be found as corneal topography is used more, thanks to its grea...
متن کامل[Hybrid material contact lens in keratoconus and myopic astigmatism patients].
PURPOSE To evaluate comfort and visual performance in relation to two different used contact lens types: hybrid material (HM) and rigid-gas-permeable (RGP), in patients with regular myopic astigmatism and with keratoconus. METHODS A randomized, double masked, prospective study of 22 patients with the diagnosis of myopic astigmatism (8 with myopic astigmatism and 14 with keratoconus) was condu...
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...
متن کاملContact lens related quality of life in patients with keratoconus.
OBJECTIVES To assess the impact of the different types of contact lenses (CLs) on quality of life (QoL) in patients with keratoconus based on self-reported results from The Contact Lens Impact on Quality of Life (CLIQ) Questionnaire. METHODS Consecutive keratoconus patients who wore CLs (rigid gas permeable [RGP], hybrid or soft toric) at least in one eye were asked to complete the CLIQ quest...
متن کاملHigh Dk piggyback contact lens system for contact lens-intolerant keratoconus patients
BACKGROUND The aim of the study was to examine the clinical success of high Dk (oxygen permeability) piggyback contact lens (PBCL) systems for the correction of contact lens intolerant keratoconus patients. METHODS Sixteen patients (29 eyes) who were not able to wear gas-permeable rigid lenses were included in this study. Hyper Dk silicone hydrogel (oxygen transmissibility or Dk/t = 150 units...
