AimTo evaluate the performance of “Tromb tip”, a new phacoemulsification tip for cataract surgery and to report outcomes after an 18-month follow-up period.Aim and MethodsFifty-two eyes of 52 patients (24 male and 28 female; mean age 67±12 years), scheduled for phacoemulsification cataract surgery were included in the study. All patients underwent a 2.1 mm clear corneal incision, biaxial phacoemulsification with the flat-shaped “Tromb tip”, and a foldable intraocular lens (IOL) implant. All patients underwent complete ophthalmologic examination, corneal topography, and non-contact specular microscopy 1 week before and 12 months after surgery. Visual outcomes, surgical induced astigmatism (SIA), central corneal endothelial cell (CCEC) count and surgical instrumental parameters were considered in the analysis.ResultsThe mean best corrected visual acuity increased from 0.4 to 0.9; mean SIA was 0.55±0.50 diopters; and, CCEC loss was 7±5%. There were no intraoperative or postoperative complications in our cohort of patients. Surgical phacoemulsification duration ranged from 45 to 180 s. Mean ultrasound percentage was 25% (range 10-40%). Mean vacuum rate (Venturi pump) was 90 mmHg.DiscussionThe Tromb-tip has a flat tip that fits well in the corneal incision without inducing stretch or deformation. There is greater surface contact between the tip and the cornea, thus causing less friction energy and heat production per unit of contact area. The 17 Gauge lumen, also maximizes aspiration (which requires greater irrigation) and shortens surgical time.ConclusionThe Tromb-tip is a good alternative to the traditional round phaco-tips.
