ABSTRACT

Purpose: To evaluate the efficacy, reproducibility and safety of hard nucleus cataract phacoemulsification (Phaco) with Neosonix.
Methods: This prospective study comprised 30 eyes, of 26 patients, with hard nucleus cataract that had Phaco and intraocular lens (IOL) implantation, with Stop and Chop and «T-Chop» techniques. The studied variables included specular microscopy, corneal pachymetry, ultrasound (US) time and power used, and visual capacity (VC) preoperative and at 1, 7, and 30 days postoperative.
Endothelial cell loss was 10%, using an average US time of 1.44 minutes, and US power of 64%. On the first day postoperatively, corneal oedema was present in 38% of the patients with an increase of 12% in pachymetry. All the patients had a satisfactory clinical recovery at the first month, returning to their preoperative corneal pachymetry numbers. Final VC ranged between 20/20-20/30 in 82.14% of the cases.
Conclusions: Phaco with Neosonix is a safe technique in the treatment of hard nucleus cataract, with a satisfactory visual outcome.
