Abstract

In this work we studied the effect of the speed of insertion of the IOL on the surgical wound structure .We included 80 eyes in this study divided into 2 group: group A with wound size 2.4mm CCI, and group B with wound size 2.2mm CCI. Each group was subdivided into subgroups F i.e. fast introduction and S ie slow introduction. The IOL used was Acrysof SN60WF (Alcon laboratories, Inc) using the Monarch III injector using D cartridge.
The demographic data of the 4 subgroup were almost similar with no significant differences concerning the age, sex, the eye (right or left) and the mean IOL lower implanted. These findings ensure homogenecity of all subgroup studied.
Our findings denote less impact on the surgical wound with fast IOL insertion than with slow insertion. In group A, there was no significant difference in wound size before (2.41 ± 0.003) and after IOL insertion (2.43 ± 0.06) in the fast group while in the same group and with slow insertion there was a significant widening of the wound size: being 2.42 ± 0.04 before IOL insertion and 2.46 ± 0.06 after IOL insertion. In group B, with wound size of 2.2mm, there was a significant difference in wound size just before IOL insertion (2.21 ± 0.02) and after the IOL insertion (2.23 ± 0.05) in fast insertion. In the slow subgroup there was also a statistical difference between just before IOL insertion (2.21 ± 0.02) and after the IOL insertion (2.25 ± 0.06).
This means that in the 2.2mm group, both fast and slow insertion speeds caused a significant enlargement in the wound size. The degree of enlargement was more in the slow subgroup.
We found a need to hydrate the wound to ensure sealing in 65% of the slow subgroup in group A, 35% of the fast subgroup in group A, 60% of the slow subgroup in group B, and 30% of the fast subgroup in group B.
All comparisons were statistically non significant but we found a need for hydration more in the slow subgroups compared to the fast subgroups.
We also studied the impact of the speed of insertion of the IOL on the surgically induced astigmatism. There were no statistical differences in the SIA in both groups A and B and the two speeds fast and slow.
We performed anterior segment OCT for some of the cases to study the profile of the clear corneal incision and the effect of the speed of insertion of the IOL on wound architecture. No Statistical conclusion could be deduced due to the small number of cases studied. This was due to logistic difficulties. We have seen cases with wound gaping at the epithelial side wound gaping at the endothelial side, and local detachment of Descemet’s membrane.
