Modified Canabrava technique with a 4-closed loop intraocular lens injected into the anterior chamber

The goal of this study was to describe and assess the efficacy of a new modification for scleral fixation of a 4-eyelet foldable intraocular lens (IOL) using a previous IOL injector in the anterior chamber. An uncontrolled case series was used to investigate the efficacy of this new modification of the original Canabrava technique. Intraocular pressure and visual acuity data were obtained preoperatively and postoperatively. Surgeries were performed with the new modification of the Canabrava technique in 12 patients with implantation incisions as small as 2.2 mm (3.2 to 2.2 mm). The follow-up period ranged from 1 to 13 months. Corrected distance visual acuity improved significantly in all 12 patients, from 0.38 to 0.31 logMAR, whereas the cell count from specular microscopy decreased in average (preoperatively 2191 cells/mm 2 ; postoperatively 1843 cells/mm 2 ) and median (preoperatively 2225 cells/mm 2 ; postoperatively 1902 cells/mm 2 ). This current modification of the Canabrava technique greatly simplifies the procedure, making it easier and faster and with a shorter learning curve.
