  1. The ‘Normal’ Eye Iris Retina Cornea Optic Nerve Lens

  5. Central Cataract no light enters the eye Here also the person is not able to see anything Though the cataract is not mature

  6. Latest technique to remove the cataratatous lens through a small key hole opening called PHACOEMULSIFICATION

  7. INCISION 2.2 mm small self sealing OPENING

  8. INCISION anterior layer of the lens is removed CAPSULOREXHISIS

  9. CAPSULOREXHISIS

  10. PHACO PROBE INSERTED A phaco probe is inserted which uses ultrasound to cut the lens into small pieces

  11. LENS CUT A phaco probe is inserted which uses ultrasound to cut the lens into small pieces

  12. LENS CUT phaco probe is inserted which uses ultrasound to cut the lens into small pieces

  16. LENS REMOVED phaco probe removes the cut pieces of the lens

  17. LENS REMOVED All pieces are removed

  18. FOLDABLE INTRAOCULAR LENS

  19. FOLDABLE INTRAOCULAR LENS Introocular lens is 13 x 6 mm 13 mm 6 mm

  20. FOLDABLE INTRAOCULAR LENS OPENING IS ONLY 2.2 mm

  21. LENS FOLDED Intraocular lens is folded 3 mm

  22. This intraocular lens is injected through the 2.2 mm opening

  23. FOLDED LENS UNFOLDS The lens unfolds like a flower inside the eye

  24. ADVANTAGES OF PHACOEMULSIFICATION • It helps Patient’s •  Early rehabilitation • Less post operative discomfort • Less induced astigmatism • Minimum post operative restriction • More satisfied The surgery is • Stitch less • Bloodless • Painless • Controlled • No injection • No eyepad

  25. Extra Capsular Cataract Extraction ECCE Old or Conventional Surgery

  26. 12 mm opening made in the eye

  27. CAPSULOREXHISIS anterior layer of the lens is removed

  28. CAPSULOREXHISIS

  29. Manually lens removed
