Patient | Diagnosis | Procedure/performance |
---|---|---|
1. Male, age 25 | Keratoconus | Pre-Descemet air bubbles, DM rupture, conversion into PKP |
2. Male, age 32 | Keratoconus | Big bubble, DALK |
3. Male, age 39 | Keratoconus | Pre-Descemet air bubbles, DM rupture, conversion into PKP |
4. Male, age 38 | Corneal dystrophy Francois | Big bubble, DALK |
5. Male, age 64 | Herpetic stromal scarring | Pre-Descemet air bubbles, microbubble incision technique, DALK |
6. Male, age 49 | Herpetic stromal scarring | Pre-Descemet air bubbles, microbubble incision technique, DALK |
From 6 patients, 4 received DALK, whereas 2 procedures had to be converted into PKP because of larger Descemet's membrane rupture during deep lamellar preparation. In both patients, no big-bubble formation was achieved.
DALK, deep anterior lamellar keratoplasty; DM, Descemet's membrane; PKP, perforating keratoplasty.
