Partial coherence interferometry in a teaching hospital.
نویسندگان
چکیده
Partial coherence interferometry (PCI) has an 8% to 22% failure rate for a variety of reasons such as mature cataract, inability to fixate secondary to macular degeneration, tremor, keratopathy, nystagmus, and vitreous hemorrhage. The new composite IOLMaster version 5 software has demonstrated a failure rate of 7.4%, primarily because of posterior subcapsular cataracts. Few studies of the efficacy of PCI in a teaching hospital setting have been done. We investigated the PCI failure rate with the IOLMaster (Carl Zeiss Meditec) in a resident ophthalmology clinic at a Veterans Affairs hospital. After investigative review board approval was obtained, the biometric measurements of 147 consecutive patients (165 eyes) who had resident-performed cataract surgery from September 2007 to June 2008were examined. Thirty-nine patients (42 eyes) were excluded because of incomplete electronic medical records (EMRs). One hundred eight patients (123 eyes) met the inclusion criteria; 106 were men (98.1%). The mean age of the patients was 72.4 years (range 50 to 91 years). Forty-six eyes (37.4%) were documented

متن کاملEstimation of Earthquake Damage Through Radar Interferometry (Case study: Bam 2003 Earthquake)
The estimate of the damage caused by the earthquake and other natural disasters in the first days after the occurrence of these events can provide a quick damages assessment and help to manage the crisis. Several methods are available to investigate the extent of earthquake’s damage. Optical remote sensing, photogrammetric methods (UAVs and LIDARs), radar interferometry (InSAR) and field observ...
