Brief Summary:
To compare the efficiency of surgical procedures using 2 phaco tip designs in torsional phacoemulsification using the bevel-down technique.

Condition or disease Intervention/treatment Phase
Cataract Device: Mini-flared Device: Reversed tip Phase 4

Detailed Description:

In this prospective, comparative, masked study, patients will be randomly assigned to have torsional coaxial microincision cataract surgery using either the mini-flared 45-degree Kelman tip or reversed mini-flared 30-degree Kelman tip. Clinical measurements will include preoperative and 3-month postoperative corrected distance visual acuity (CDVA), endothelial cell counts (ECC) and preoperative and 1-day postoperative central corneal thickness (CCT). Intraoperative measurements will include phaco time, torsional time, aspiration time, case time, cumulative dissipated energy (CDE) and balanced salt solution volume (BSS).

The study was performed according to established ethical standards for clinical research Institutional Review Board (IRB) of the University of Sao Paulo in Brazil, conducted between November 2010 and February of 2011. All surgeries will be performed at the University of Sao Paulo. Physicians conducting postoperative evaluation will not have access to patients' medical records. Exclusion criteria will be previous ocular surgery, central endothelial cell count less than 2000 cells/mm2, glaucoma or intraocular pressure greater than 21 mmHg, amblyopia, retinal abnormalities, steroid or immunosuppressive treatment and connective tissue diseases. Enrolled patients who have complicated cataract surgery (eg, posterior capsule rupture, vitreous loss, or an intraocular lens not placed in the capsular bag) will be subsequently excluded.
