Abstract

Today, cataract surgery has become a technically advanced and very
standardized procedure. Posterior capsule opacification is the most
common post-operative problem, which results in a decrease of the visual
acuity. In our study, we have evaluated the effect of anterior capsule
polishing on the development of PCO.
In this study, a comparison was made between two groups. In group one
polishing of the anterior capsule using Koch aspiration cannula (Geuder)
was done. In group two, phacoemulsification was completed without
polishing of the anterior capsule. The two groups were compared in terms
of V.A, IOP and severity of PCO which was assessed both clinically and
objectively using Open Access Systematic Capsule Assessment (OSCA)
program.
This study proved that polishing of the anterior capsule is effective in
decreasing the severity rather than prevention of PCO. This was
evidenced by the fact that average (OSCA) score in group 1 following
first month is 1.0012 versus 1.6949 in group 2 (P value = 0.0006).
Following 6 months values were 1.29781 & 1.8169 respectively (P value
= 0.1574), denoting statistically significant difference between OSCA
values after first month that turned to be statistically nonsignificant after
six months period.
In this study, change of BCVA over six months correlated with changes
in (OSCA) score.Following first month, average BCVA in group 1 was
0.71±0.26, and in group 2 was 0.54±0.25.As for BCVA after six months,
group 1 had an average of 0.59±0.26 versus 0.4±0.18 in group2.
This study also showed that polishing the anterior capsule affects the
morphology of PCO. Polishing decreases the incidence of development
of Elschnig pearls.
OSCA program has proved to be user friendly, reproducible and cheap.
It’s important to investigate the role of anterior capsule polishing in high
risk groups e.g.: uveitic patients, patients with PXF or in retinitis
pigmentosa. Also, further studies with longer follow up periods are
recommended.
