Objective

To evaluate the safety, potential complications, and surgical applicability of the Pulsed-Electron-Avalanche-Knife-fine cutting (PEAK®-fc) for capsulotomy in children.

Methods

A prospective, consecutive trial including ten children with age ranging from 2 to 6 years, undergoing cataract surgery and implantation of posterior chamber intraocular lenses. The advanced PEAK®-fc was set at voltage of 600 V, with a repetition rate of 30Hz and 30 minipulses per pulse of 100μs duration. The 0.6mm protruding wire with a diameter of 50μm was used to create a circular capsulotomy of the anterior (n = 5) and of the anterior and posterior capsule (n = 5).

Results

The success of anterior and posterior capsulotomy depended on two factors: Velocity of movement and distance of the protruding wire from the surface of the lens capsule. Best results could be obtained with the wire just gently touching the capsule and slow velocity of approximately 1-2 mm/s in a circular manner. The edges of the cut obtained appeared very sharp edged and smooth with minimal collateral damage.

Conclusions

The PEAK®-fc recently has been introduced for tractionless cutting in ophthalmic surgery. PEAK®-fc greatly facilitates circular capsulorrhexis especially in cases in which the elasticity of the lens capsule may complicate this surgical maneuver, as during cataract surgery in young children.
