Presentation Transcript

  1. Corneal complication of phacoemulsification

  2. Historical cataract surgery • lens dislocation • Extracapsular cataract extraction • Intracapsular cataract extraction • Extracapsular cataract extraction

  3. Intraocular lens implantation • Phacoemulsification • Foldable lenses

  4. Small incision • Multifocal lenses • Accommodative lenses • MIC

  5. Pachymetry • Cell counting • Ambulating surgery

  6. Shorter the time • Faster rehabilitation • Better visual acuity • Far Near

  7. Phacoemulsification = less complication

  8. Complications Epithelial • Traumatic • Drags and antiseptics

  9. Incisional • Irregular incisional • Clear corneal problems • Corneal folding • Descemets trauma

  10. Stromal dissection • Scars • Astigmatisem • Woumd burn • Suture problems

  11. Knifes • 1.5 mm , 3.2 mm • Shape • Sharpness • Material

  12. Incision sight • Superior • Temporal • Oblique • Incision shape • One plane • Two planes • Tree planes

  13. Irrigation (A.C forming) • Stromal hydration • Descemets trauma • Endothelial trauma

  14. Capsulorehexis • Needle • Forceps

  15. Hydrodisection • Descemets trauma • Endothelial trauma

  16. Phaco prop • Epithelial • Stroma • Descemets • Endothelial

  17. Fluidic irrigation • Severity • Time • Direction

  18. Phaco • Machine • Needle • Percent • Time • Continuous pals • Endothelial distance • In the bag • In the papillary plane • In the A.C

  19. Direct trauma to the endothelium • Chopper • Phaco needle

  20. Infection • Bacteria wound infection • Fungal wound infection • Herpetic keratitis

  21. Strile ulcerations and stromal melting • Rheumatoid arthritis • Collagen vascular disease • Keratoconjunctivitis sicca

  22. Symptoms and signs • Epithelial defect • Punctuate • Localized • Diffused or huge defect • Wound leakage

  23. Corneal edema • In the operation time (epithelial) • The day after surgery • Localized incisional • Suture tightness • Endothelial damage • Near the wound • Wound burn

  24. Central corneal edema • Endothelial damage • Cell slipping • Cell death • Deep stromal damage • Decimates detachments • Localized stripping • Massive • Diagnosis • Differentiation with anterior capsul

  25. Total corneal edema • In the day after surgery • Without hot symptoms

  26. Pigment realizing from the iris • Pupillary dilation • Iris atrophy toxic keratopathy

  27. Management • Epithelial • Dry eye • Toxicity • Exposure lid lag • Entropion

  28. Suture tightness

  29. Descemets detachment * In surgical plane * The day after surgery • Descemets folding • Descemets rolling

  30. Total corneal edema • Rollout endophthalmitis • IOP • Inflammation • Cycloplegics • Steroids

  31. Astigmatism • Suture • Persistent

  32. Corneal opacities • Corneal scars

  33. Grafting procedures
