Purpose

The main purpose of this study was to evaluate the effects of uneventful phacoemulsification on the central corneal thickness (CCT) in pseudoexfoliative eyes during the first month postoperative period and compare these changes to eyes without pseudoexfoliative (PXF) syndrome.

Other purpose was to study the possible association between

1. The axial length (AL) and the CCT

2. The cumulative dissipated energy (CDE) and the CCT

3. The volume of BSS (BSS) and the CCT

in eyes with and without PXF syndrome.

Setting

General Hospital of Chios "Skilitsio", ophthalmology department

Methods

A total of 12 eyes of 12 consecutive patients with cataract and PEX syndrome that underwent uneventful phacoemulsification were enrolled in this study. A control group of 27 eyes of 27 patients with cataract and without PXF was employed for comparison. CCT measurements were obtained preoperatively and at 1day, 10 day and 1 month postoperatively with the anterior segment-OCT. AL was measured preoperatively with ultrasound. CDE and BSS were measured at the end of every surgery.

Results

There was no significant difference in the mean of CCT between the two groups preoperatively and postoperatively .The only significant difference that we found between the two groups was in the change of CCT from the baseline the first day after the surgery. In the PXF group the CCT was 34,815 μm (p-value:0,047) thicker in comparison with the CCT of the eyes in the control group.

There were not found any statistically significant associations between AL and CCT or CDE and CCT. It was found a negative significant association between BSS and CCT in the control group 10 days after the surgery. In both of groups the mean of CCT increased at day 1and returned to the normal baseline values at 1 month.

Conclusions

Eyes with and without PXF syndrome exhibit similar features before and after phacoemulsification. A surgery in early stages of cataract in PXF syndrome, not only provides a non complicated surgery, but also leads to a less damaged cornea similar to eyes without PXF.
