  • Figure 1 shows the patient's cornea OD with a small amount of fluorescein instilled following lens removal. (clspectrum.com)
  • Both the lens and cornea which protects it refract incoming light to focus it on the retina. (google.com.au)
  • The lens supplies approximately 20 diopters of correction, while the cornea provides about 40 diopters. (google.com.au)
  • 7 - 13 There is a theoretical model stating that the post-lens tear layer thickness should be less than 150μm to avoid hypoxic effects on the cornea. (clspectrum.com)
  • A third type is a toric lens, which corrects for astigmatism, an irregularity in the curvature of the cornea. (nyee.edu)
  • retina
  • The human cornea serves both as a protective outer cover to the eye and as the primary refractive element responsible for focusing light back to the retina. (arvojournals.org)
  • avascular
  • We herein describe a novel mouse model of spontaneous, secondary lymphangiogenesis in the normally avascular cornea. (ox.ac.uk)
  • In summary, destrin deletion has differential effects on spontaneous hem- and lymphangiogenesis in the normally avascular cornea and represents a novel mouse model to study the mechanisms of lymphangiogenesis and to test the antihem- and antilymphangiogenic properties of known or new antiangiogenic agents.

  • ocular surface
  • Patients underwent the Ocular Surface Disease Index (OSDI) questionnaire, tear film break-up time, corneal staining, Schirmer test I, and LSCM of the limbus. (arvojournals.org)
  • Laser scanning confocal microscopy and IC documented antiglaucoma therapy induced morphologic alterations of limbus, which may play a role in the glaucoma-related ocular surface disease. (arvojournals.org)
  • The use of scleral lenses to treat complex corneal diseases (i.e., irregular corneas and/or ocular surface disease) also continues to grow. (clspectrum.com)
  • represents
  • cell culture The cornea represents the primary protection, focusing, and transmission interface for light entering the eye. (docme.ru)
  • collagen fibers
  • The purpose of this study was to characterize the three-dimensional distribution of transverse collagen fibers along the major meridians of the cornea using an automated method to rapidly quantify the collagen fibers' angular orientation. (arvojournals.org)
  • donor
  • The cornea of New Zealand rabbits was burned by placing a Whatman filter paper (8.00 mm in diameter) soaked in 1 N NaOH onto the cornea for 60 seconds followed by washing with PBS for 60 seconds and allowed the injured cornea to heal for 20 days prior to corneal transplantation using a donor cornea collected from Angola rabbit.
