Posterior capsule opacification occurred in more than one-third of eyes within 3 years after phacoemulsification, and IOL type and surgeon experience may be predisposing factors, according to a large study.
Data culled from the Australian Prospective Cataract Surgery and Age-related Macular Degeneration study included 1,495 patients who underwent phacoemulsification and IOL insertion.
Investigators analyzed relationships between the incidence of PCO, surgeon experience, and IOL design and material.
The overall incidence of PCO was 38.5% at 3 years; the incidence of severe PCO was 4.7%.
PCO was identified in 64% of eyes implanted with hydrophilic IOLs, 51% of eyes with square-edged three-piece hydrophobic IOLs, 39% of eyes implanted with partial-round-edged three-piece hydrophobic IOLs, and 34% of eyes implanted with square-edged single-piece hydrophobic IOLs.
The incidence of PCO was 48.8% in cases performed by junior surgeons and 36.3% in cases performed by senior surgeons.
