PURPOSE: To compare visual outcomes after cataract surgery with bilateral implantation of 2 intraocular lenses (IOLs): extended range of vision and trifocal. METHODS: Each group of this prospective study comprised 40 eyes (20 patients). Phacoemulsification followed by bilateral implantation of a FineVision IOL (group 1) or a Symfony IOL (group 2) was performed. The following outcomes were assessed up to 1 year postoperatively: binocular uncorrected distance visual acuity (UDVA), binocular uncorrected intermediate visual acuity (UIVA) at 60 cm, binocular uncorrected near visual acuity (UNVA) at 40 cm, spherical equivalent (SE) refraction, defocus curves, mesopic and photopic contrast sensitivity, halometry, posterior capsule opacification (PCO), and responses to a patient questionnaire...

Fracture of an intraocular lens (IOL) haptic is a rare complication of cataract surgery. A broken haptic can cause serious damage in the anterior and posterior segments. To the best of our knowledge, a broken haptic in a high-quality, commercially available trifocal IOL has not been documented in the literature. Prompt and proactive action at 1 day postoperatively aided in addressing the complication and restoring the vision. We suggest that the ophthalmologist performed a thorough evaluation on the 1(st) postoperative day and take immediate action after a discussion with the patient and relatives...

Maxillary segmental defects are a reconstructive challenge particularly when the anterior arch is involved. Missing bone, mucosa, and teeth should be replaced; fistulae closure should be guaranteed by bone and mucosa continuity; stable functional occlusion should be achieved; and facial aesthetics restored. These defects resulting from tumor excisions, if left untreated, will cause additional problems related to interposed scar and collapse of lip and nose. Immediate reconstruction should avoid these problems and should be considered when safe tumor-free margins are obtained...

Synchronous colorectal cancers (SCRCs) have been increasingly diagnosed due to emerging diagnostic modalities. The presence of three or more synchronous colorectal cancers has, however, only rarely been reported. A 76-year-old white man presented for management of two concurrent colorectal adenocarcinomas in the left colon evidenced on total colonoscopy. Preoperative abdominal ultrasonography and thoracoabdominal computed tomography were negative for metastatic disease. The patient underwent an elective left hemicolectomy...

Because of the high failure rates, large alveolar cleft defects cannot be successfully closed with bone grafting. Vega introduced the use of the hyrax screw for the closure of such defects by distraction osteogenesis. However, his technique was more invasive with a difficult adaptation of the appliance at the surgical table. To overcome these limitations, a completely tooth-borne trifocal distraction appliance was devised and placed after osteotomy in a 22-year-old repaired group 3 cleft patient who had a 15-mm alveolar defect on the right side...

Jian Chen, Bingxi Jia, Kaixiang Zhang
In this paper, a trifocal tensor-based approach is proposed for the visual trajectory tracking task of a nonholonomic mobile robot equipped with a roughly installed monocular camera. The desired trajectory is expressed by a set of prerecorded images, and the robot is regulated to track the desired trajectory using visual feedback. Trifocal tensor is exploited to obtain the orientation and scaled position information used in the control system, and it works for general scenes owing to the generality of trifocal tensor...

We report on a case in which trifocal distraction osteogenesis was applied in a patient with a mandibular defect caused by resection of an ossifying fibroma. During the surgical procedure, we accidentally dissected the surrounding periosteal tissue of the left transport completely in the process of transport disc preparation and made the disc into a free bone graft. However, we still used this transport and successfully completed the distraction osteogenesis. The patient's facial and occlusal function were regained after treatment...
