![]() | Media file 1: Diagram of a contact lens. |
![]() | Media file 2: Topographic map shows corneal steepening inferiorly. This is typically seen in patients with keratoconus. |
![]() | Media file 4: Transplant rejection with central keratic precipitate and an arcuate epithelial rejection line. |
![]() | Media file 5: Lenticulated, aphakic contact lens with a minus carrier. Note that the fluorescein is thick peripherally. |
![]() | Media file 6: Child with a spherical, silicone elastomer lens (SilSoft lens; Bausch & Lomb, Rochester, NY) in the left eye. |
![]() | Media file 7: Painted polymethylmethacrylate (PMMA) lens used after traumatic iridodialysis on the right eye to relieve persistent photophobia. |
![]() | Media file 9: Bitoric lens fit on a patient with 7 diopters of corneal toricity. |
![]() | Media file 10: LifeStyle rigid gas-permeable, bifocal lens (The LifeStyle Company, Inc, Morganville, NJ). Note that proper centration ensures good distance acuity and effective near add. |
![]() | Media file 12: This lens fit depicts an excessively steep lens with a resultant air bubble. |
![]() | Media file 13: The patient whose eye is depicted in this image presented with poor vision as a result of Salzmann nodules. The best lens to use first in this patient is a spherical lens. |
![]() | Media file 14: The spherical lens fit depicted shows inferior decentration with marked corneal toricity. |
![]() | Media file 15: This image depicts corneal neovascularization in a 31-year-old professional football player with keratoconus. |
