PCO prevention by polishing the capsular bag

Objective: Cataract surgery may achieve a new level in quality, if the occurrence of PCO could be minimized or even prevented.
Methods: Lens epithelial cells can be removed from the capsular bag without any capsular rupture, by an impact of a shock wave with fast rise time, but low intensity. The shock waves are generated by a laser system from the company A.R.C. Laser, which can also be used for lens emulsification (Photolysis). Pulses used for polishing the capsular bag have lower intensity as used for lens emulsification. The application of the shock wave is done by special hand pieces with a bend needle design, which helps to apply the shock wave pulses for polishing in the entire capsular bag. After successful cataract extraction, first of all the anterior capsular bag at the rhexis edge was cleaned.
Results: Up to 12 months post op, there is a clearly visible difference between the untreated areas, which show cell grows after 2 weeks and the polished areas, which remained nearly cell free. It even seems, that there is an influence on the equatorial cells, because in every case of PCO occurrence, its origin was the untreated area.
Conclusions: With the shock wave of a photo disruption, created by a Nd:YAG laser, lens epithelial cells can be selectively removed from the capsular bag. The further development of this method could mark a successful PCO prevention.
