Keratoconus: Diagnosis, contact lens fitting and management
Numerous studies have reviewed the prevalence of keratoconus. 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 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...
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 کاملClinical performance of a new hybrid contact lens for keratoconus.
OBJECTIVES To compare the clinical performance of the Clearkone hybrid contact lens for the treatment of keratoconus against the habitual contact lens of the patients. METHODS A total of 33 eyes from 18 patients were fitted with the Clearkone. High- and low-contrast visual acuity (HCVA and LCVA), central corneal thickness (CCT), and contrast sensitivity acuity (CSF) were recorded with habitua...
متن کاملKeratoconus Management: Role of GP Contact Lenses
Keratoconus is a corneal disorder progressive characterized by thinning and steepening of the central and paracentral cornea, which leads to protrusion [1]. The exact cause of the disease remains to be fully elucidated although its etiology probably is multifactorial with a genetic predisposition to keratoconus influenced by external environmental factors (eye rubbing and atopy) [2] with differ...
