Abstract Details

Purpose:

The aim of our study is to compare the loss of corneal endothelial cells after phacoemulsification in patients with pseudoexfoliation syndrome (PXF) and normal controls (no-PXF).

Setting:

Despite modern techniques and technologies of cataract surgery, the pseudo-exfoliation syndrome is a great challenge for cataract surgeons. An increased risk of endothelial cell loss may be expected in these patients following more complicated and prolonged surgery, requiring complex manipulation in the anterior chamber.

Methods:

Phacoemulsification and a monofocal intraocular lens implantation were performed on thirty patients with PXF (30 eyes) and 30 normal control patients no-PXF (30eyes) by experimented cataract surgeon. Specular microscopy were performed in all patients to evaluate characteristics of corneal endothelial cells) the density, percentage of hexagonal cells, coefficient of variation of the corneal endothelial cells and central corneal thickness preoperatively at 6 weeks and 3 months after surgery. The age of selected patients were between 55 and 65 year old. Ocular biometry were evaluated with Aladdin (TOPCON).

Results:

Preoperative count of endothelial cells was lower in the PXF group. The effective phacoemulsification time (EPT) was similar in the two groups. Mean postoperative endothelial cell density was significantly lower in the two groups (p <0.05). The percentage of endothelial cell loss was significantly higher in the PXF group than in the no-PXF group at post-operative 6 weeks and three months. Mean central corneal thickness was similar between groups throughout the follow-up period.

Conclusions:

We have found a significant endothelial cell loss in pseudoexfoliation syndrome. Preventive measures such as the use of dispersive viscoelastic solutions providing more endothelial protection, as well as the reduction of operating time and ultrasound energy are recommended during phacoemulsification in this patient’s profile.
