Short-Term PCO in Cataract Surgery Using Low- and High-Vacuum Technique
Narrative Responses:
Purpose
To compare the amount of short term posterior capsular opacification (PCO) in low vacuum technique, which widely used with advantage of minimal corneal endothelial damage and low effect on corneal thickness, and high vacuum techinique.
Methods
Phacoemulsification was performed by a single surgeon and divided into 2 groups, phacoemulsification with low vacuum technique and with high vacuum technique. We compared the amount of PCO, which was scored using retroillumination method and POCOman software system at post-operative 1 week, 1 month, 3 month and 6 month.
Results
The amount of PCO at post-operative 3month in phacoemulsifiaction with low vacuum technique group was statistically significant higher than with high vacuum technique. (p<0.05)
Conclusion
Phacoemulsification using low vacuum technique can be safe method in the aspect of little effect on corneal endothelium and corneal thickness than high vacuum technique, but has a disadvantage of higher incidence rate of PCO than high vacuum technique.
