Purpose:
Retrospective evaluation of different types of Big Bubbles during DALK in 100 cases. classification of bubbles depends on many factors:
- progressive or explosive bubbles
- Big bubbles after single, 2nd, 3rd or even 5th air injections
- ordinary or inverted big bubbles
- challenging cases of big bubbles
Setting:
: Ophthalmology Department - Cairo University, EGYPT and Al-Nour Eye Hospital, Cairo Egypt
Methods:
Deep Anterior Lamellar Keratoplasty (DALK) was done in 100 cases using the Big Bubble Technique using sharp needle in the early cases replaced later by blunt cannula.
Results:
- failure to obtain big bubble in 15%
- progressive big bubble in 10%
- explosive big bubble in 70% (40% single injection, 20% 2nd injection, 8% 3rd injection and 2% after 5th injection )
- complicated mechanics in 4%
- inverted big bubble in 1%
Conclusions:
Big Bubble formation during DALK takes different shapes depending on many factors during air injection
