This document provides 5 tips for improving visual outcomes after repair of a corneal laceration: 1. Use antibiotic prophylaxis by injecting antibiotics through the wound. 2. Use amniotic membrane overlay for severely lacerated wounds to promote healing and reduce inflammation. 3. For traumatic cataracts with an open anterior capsule, carefully remove lens material from the anterior chamber to avoid dropping lens fragments or vitreous prolapse. 4. Provide refractive correction and consider amblyopia therapy. Determine refractive error through trial lenses, topography, or binocular trials if there is corneal opacity. 5. Thank God for the advice and cases presented on improving outcomes after corneal laceration repair.

5 advises to improve visual outcome
of repair of corneal laceration

4. 1
Antibiotic Prophylaxis
Inject through the wound or side port
Avoid intravitreal injection except if there is evidence of
endophthalmitis or IOFP as injection in soft tesnsion can
induce lens , retinal or choroidal injury

5. Hypopyon?
· Presence of hypopyon particularly in
neglected wounds and pediatrics not
equal endophthalmitis but may be just
reaction.

6. 2
Amniotic Membrane On-lay
for severely lacerated
wound

10. Leaky wound
Tight sutures
Astigmatism
Glue / AMT
Increase

sutures
Opacity
PKP

11. Role of AMT
· Close small defects : decrease number
of sutures / pupil sparing sutures
· Prevent over tight suturing
· Stimulate healing.
· Anti-inflammatory
ConvertsLacerated Incision to Blade incision

12. Too aggressive

13. Surgical technique
 Strip of AM is applied to the wound
from the start.
 Wound is sutured with interrupted
nylon 10/0 sutures including the AM
strip.
 Suturing is avoided in the visual axis
 Bandage soft CL is applied.

39. Post operative complications
· Early post operative hypotony
· Early membrane displacement
· Difficult suturing and membrane tears
· ? Poor intraocular visualization

40. 3
Traumatic Cataract with
open anterior capsule

41. Problem with traumatic
cataract
· Posterior capsule usually open.
· Prolapsed Vitreous = incomplete removal
of lens matter.
· Dropped lens = severe vitritis.
· Cyclitic membrane or vitrectomy ==
Atrophia.

42. Prognostic factors
· Surgeon experience
· Age of the patient
* < 10 ys
* 15 – 25 ys
* Hard cataract
· Size of the corneal wound

43. Advantage to do
· Avoid near second anesthesia
· Removal of IOFP

44. Technique
· Close the wound 1st.
· Dilate pupil and
· Identify the capsular
· opening
· 2 side ports perpendicular to capsular
tear.

45. AC should be stable with
Healon
· Gradual prolapse of the lens matter in
the AC using viscodissection.
· Slow motion I/A in the AC with
injection of OVD once AC get shallow

46. AC should be stable with
Healon
· Very deep AC = lens matter will drop
· Very shallow AC = vitreous will
prolapse.
