Corneal aberration changes after rigid gas permeable contact lens wear in keratokonic patients
PURPOSE To determine the short-term effect of rigid gas permeable (RGP) contact lenses on corneal aberrations in keratoconic patients. METHOD Sixteen keratoconic eyes with no history of RGP lens wear were included. They all had corneal aberrometry using Pentacam, and different aberration indices of the anterior and posterior surfaces of the cornea were measured before and 3 months after fitti...
متن کاملChanges in diadenosine polyphosphates during alignment-fit and orthokeratology rigid gas permeable lens wear.
PURPOSE To evaluate the levels of dinucleotides diadenosine tetraphosphate (Ap(4)A) and diadenosine pentaphosphate (Ap(5)A) in tears of patients wearing rigid gas permeable (RGP) contact lenses on a daily wear basis and of patients wearing reverse-geometry RGP lenses overnight for orthokeratology treatment. METHODS Twenty-two young volunteers (10 females, 12 males; 23.47 ± 4.49 years) were fi...
متن کاملShort-term corneal changes with gas-permeable contact lens wear in keratoconus subjects: a comparison of two fitting approaches.
PURPOSE To evaluate changes in anterior corneal topography and higher-order aberrations (HOA) after 14-days of rigid gas-permeable (RGP) contact lens (CL) wear in keratoconus subjects comparing two different fitting approaches. METHODS Thirty-one keratoconus subjects (50 eyes) without previous history of CL wear were recruited for the study. Subjects were randomly fitted to either an apical-t...
متن کاملImpact of rigid gas-permeable contact lens extended wear on corneal epithelial barrier function.
PURPOSE To measure the effect of hypoxia and eye closure on epithelial permeability to fluorescein (P(dc)) during rigid lens extended wear (EW). METHODS Central corneal thickness (CT) and P(dc) were measured in 42 subjects with an optical pachometer and automated scanning fluorophotometer, respectively. All subjects had been successfully wearing rigid gas-permeable (RGP) lenses on a 6-night E...
متن کاملRigid Gas Permeable Contact Lens as a Vision-Sparing Tool in Children After Traumatic Corneal Laceration.
PURPOSE To evaluate the clinical value of rigid gas permeable contact lenses in children after traumatic corneal scarring. METHODS This comparative study included 15 children (age range: 5.7 to 14 years; mean ± standard deviation = 9.4 ± 2.9 years) with corneal scars and best corrected visual acuity (BCVA) of worse than 20/20, history of penetrating ocular trauma, and/or cataract extraction. ...
