  1. Vitrectomy techniques in Paediatric Cataract Surgery Dr.Ajay I.Dudani Zen Eye Center Surya Eye Tech.

  2. Immediate Imminent PCO is the bug bear of Pead.Catatact Surgery. • This can lead to irreversible amblyopia. • Post.Capsule & Ant.Vitreous Phase are the scaffold for proliferation of LES • Hence the Rationale of primary PCCC with ant.Vit. With optic capture

  3. Approaches for Ant.Vit. • Ant. Approach from limbal side port. • Pars Plana approach 3mm post to limbus.

  4. Pathogenesis • The term PCO is misleading. • A-cells : fibrousmetaplasia fibrous PCO • E-cells : mitosis PCO with ‘pearls’

  5. Other cells involved in formation of PCO • Infammatory cells –WBCs • RBCs • Collagen deposition • Iris melanocytes

  6. Anterior capsule opacification [ACO] in extreme cases results in capsule contraction syndrome[CCS]. .

  7. Interlenticular opacification Soemmerring’s ring

  8. Ant. Vitrectomy approach - Vitrector Technique of Paediatric Cataract • G/A With ketamine with Local Lignocane Block • Scleral Tunnel • CCC With needle / Vitreous cutter • Hydrodissection • AC Maintainer inserted. • IA Done with Vitreous cutter from side port.

  9. Vitrector Technique of Paediatric Cataract • IOL inserted in the bag. • Post. CCC with Generous Ant. Vitrectomy from side port with cutter. • Wound and side port hydration

  11. Automated I/A Technique • Scleral Tunnel • CCC • Hydro-dissection • Automated I/A (irrigation/aspiration) through side ports. • IOL Inserted • Ant.Vit.+ PCC from side port.

  12. Post. Pars Plana Approach • 3mm from limbus • 2port • Infusion- bent 20G needle • Direct clean anatomical approach for generous ant. Vit. • PCCC done from behind • Less chance of vit.Prolapse in AC.
