Group | Highest IOP (mmHg) | Operation time (sec.) | Irrigation volume (ml) |
|---|
Whole eye N=10 | 55.3±5.0 | 448.4±33.4 | 40.5±9.8 |
Bisected eye N=9 | 55.8±4.7 | 497.6±57.3 | 54.4±21.9 |
P value | 0.650 | 0.028 | 0.107 |
- IOP was monitored during PEA in two groups of porcine eyes (N=10 for each group). One group consisted of whole (unbisected) eyes, while the second group consisted of bisected eyes. The bisected eyes were glued to the glass slide with superglue and wheat flour. Among the bisected eyes, 9 of 10 (90%) eyes remained fixed to the slide throughout the procedure. The eye-glass slide seal was broken in only one case during ultrasound sonication of the lens. There was no significant difference between the two groups with respect to the maximum average IOP or the mean volume of the irrigation solution (Mann-Whitney test). The procedure time was significantly longer in bisected eyes than that of whole eyes (P = 0.028 Mann-Whitney test).
