RUPTURES MANAGEMENT

Clinica degli occhi Sarnicola

1.- Complete the stromectomy !

2.- Don’t inject air into the A.C. !

3.- Suture the donor first !

4.- Then…inject air into the A.C. !!!

5.- Move the eye in order to remove

interface fluids !

6.- Patient’s head positioning.

Suggestions:

1.- Suture the zone of

perforation

2.- Layer by layer delamination

3.- Suture the donor

4.- Delaminate the zone of

perforation

5.- Then put Air into the A.C.

6.- Move the eye in order to

remove interface fluids

RUPTURES OUTCOMES:

- 75 ruptures (82,4%) resulted repaired at 1st day post-op.1 case was due to excessive corneal trephination

- 16 cases (17,6%) developed

No PK conversion was recorded !!

10 cases fixed with single rebubbling (head position)

3 cases with 2 rebubbling and suture replacement.

3 cases, with recipient bed (RB) cut due to

donor-recipient disparity of curvature

- 91 DM ruptures were recorded. (91/1084 = 8,4%)
