CATARACT SURGERY- COMPLICATIONS

COMPLICATIONS OF CATARACT SURGERY

Divided into:

  1. Related to Surgery
  2. Related to IOL

COMPLICATIONS RELATED TO SURGERY

There are so many complications of cataract surgery:

  1. After cataract (opacification of capsule)
  2. Vitreous prolapse
  3. Cystoid macular edema
  4. Endophthalmitis
  5. Aphakia glaucoma
  6. Fibrous & endothelial growth
  7. Retinal detachment
  8. Neovascular glaucoma
  9. Anterior uveitis (Iridocyclitis)
  10. Iris prolapse
  11. Stria keratopathy
  12. Corneal endothelial damage
  • Most of these complications are more common with ICCE
  • Except for after cataract which occurs in ECCE & is the most common complication of ECCE.
  • ECCE decreases the chances of all other complications.

COMPLICATIONS RELATED TO IOL

1. Malposition of lens leads to

  1. Sunset syndrome (inferior subluxation of IOL)
  2. Sunrise syndrome (superior subluxation of IOL)
  3. Lost lens syndrome (Complete dislocation of IOL into the vitreous cavity)
  4. Windshiled wiper syndrome (results when a very small IOL is placed vertically in the sulcus)

2. Toxic lens syndrome

  • Uveal inflammation.
  • Excited by either the ethylene gas used for sterlising IOL (in early case) or by toxic lens material (in late case).

3. UGH Syndrome (Uveitis. Glaucoma, Hyphaemia)

  • Occurring with rigid anterior chamber lens.

4. Complications like:

  1. cystoid macular oedema
  2. corneal endothelial damage
  3. uveitis 
  4. secondary glaucoma

Exam Important

  • Most common complication of extracapsular cataract surgery is Opacification of posterior capsule.

Causes of complicated cataract is:

  1. Pars planitis
  2. Retinitis pigmentosa
  3. Retinal detachment
  • Infective complications in cataract operation can be decreased by Antibiotic eye drops & Intraoperative antibiotics.
  • Late onset endophthalmitis after cataract surgery is most often caused by Propionobacterium Aenes.
  • Malignant glaucoma is seen in after surgery for cataract or glaucoma.
