Abstract

Purpose:: to evaluate the performance of a brand new phacoemulsification tip, called the "Tromb tip", in cataract surgery.

Methods:: Forty eyes of 40 patients (17 male and 23 female; mean age 65±11 years), scheduled for phacoemulsification cataract surgery were included in the study. All patients underwent a 2.1 mm clear corneal incision, biaxial phacoemulsification with a new flat-shaped phaco-tip called "Tromb tip", and a foldable intraocular lens (IOL) implant. A complete ophthalmologic examination, corneal topography, and non-contact specular microscopy were conducted prior to and 3 months after surgery. Instrument parameters during surgery were reported.

Results:: Postoperative results after 3 months were as follows: mean best corrected visual acuity (BCVA) increased from 0.6 to 0.9; mean surgical induced astigmatism (SIA) was 0.50±0.50 diopters; and, mean endothelial cell loss in the central part of the cornea was the 7±8%. There were no intraoperative or postoperative complications in our cohort of patients. The mean total surgical time ranged from 3 to 12 min. Phacoemulsification duration ranged from 45 to 180 sec. The mean ultrasound percentage was 25% (range 10-40%). The mean vacuum rate (Venturi pump) was 90 mmHg.

Conclusions:: The Tromb-tip is a good alternative to the traditional round phaco-tips because of it’s innovative shape. This flat tip respects the anatomic shape of the corneal incision. There is greater surface contact between the tip and the cornea, causing less friction energy and thus less heat production per unit of contact area. The 17 Gauge lumen, which is wider than the traditional tip yet fits in a small corneal incision, maximizes aspiration (requiring greater irrigation) and shortens the surgical time.
