Sutureless self-healing clear corneal incisions (CCIs)
have been in wide use since they were described by Fine
in 1992; however, it has also been debated whether CCIs
increase the risk for endophthalmitis. The relatively
recent availability of anterior segment optical coherence
tomography (AS-OCT) has allowed in vivo evaluation of
CCIs in high definition; this has resulted in more detailed
and positive findings. There are several types of CCI
according to the number of plans such as single-plane,
two-plane and three-plane. Assessment of CCI,
especially immediately after surgery, is of interest as the
integrity of the CCI may decrease the risk of
endophthalmitis and other postoperative complications.
In our study we compare between two-plane CCI and
three-plane CCI using AS-OCT according to the
Descemet’s membrane detachment, epithelial and
endothelial gaping rates and the corneal thickness after 1
week and 2 weeks post-operative. The current study
revealed that there are no statistically significant
difference between the two techniques according to the
previous data and we found that both techniques are safe
and the cause of Descemet’s membrane detachment not
depends on the techniques of CCI.
