Purpose: To compare the phacoemulsification parameters in hard nucleus with or without pseudoexfoliation (PEX) syndrome and to evaluate
intraoperative preventive manipulations to avoid surgical complications.
Materials and Methods: 241 eyes of 241 patients were evaluated. 53 eyes of 53 patients were in PEX group and the remaining 188 eyes were
in the control group (CG). All patients underwent surgery by longitudinal cold phaco, by the same surgeon with the same preoperative set-up
parameters. The phaco parameters including effective phacoemulsification time (EFT), phacoemulsification percentage (PP), ultrasound time
(UST), and surgical complications and preventive manipulations compared between groups.
Results: The mean UST was 80.41 second (sec) in PEX Group and it was 71.17 sec in the CG. UST was statistically significantly longer in
PEX group than CG (p=0.03). The mean EFT was 28.55 sec in PEX group while it was 43.29 sec in CG. The EFT was statistically significantly
shorter in PEX group than CG (p=0.008). The mean PP was 17.11% in PEX group while it was 17.82% in CG. The difference was not
statistically significant (p=0.32). The requirement of both Capsule Tension Ring (CTR) and Iris Retractor Hook (IRH) implantations were
significantly higher in PEX group than CG (p=0.001 for each one).
Conclusion: Uneventful phaco surgery in eyes with hard nucleus combined with PEX could be performed in longer period with shorter
EFT and similar PP comparing to eyes without PEX. With the help of preventive approaches the overall outcomes for patients with PEX can
be similar to those for non-PEX patients.
