Combined phacoemulsification and closed pars plana vitrectomy capability in a single computerized instrument.
The Heslin/Mackool Ocusystem allows either phacoemulsification or pars plana vitrectomy in a maximally controlled closed system. A unique flow control system maintains a constant balance between infusion and evacuation. Low flow rates and high suction levels are therefore possible without surging of intraocular contents or ocular collapse. The ultrasonic handpiece has reusable tips and is air-cooled, self-tuning, lightweight and autoclavable. The vitrectomy handpieces have a guillotine cutting mechanism or a self-sharpening rotational cutting mechanism and are as small as 0.79 mm in diameter (21 gauge). One and two-handed techniques for phacoemulsification and vitrectomy are possible through limbal or pars plana approaches.
