ABSTRACT
AlM:To investigate the factors and solutions of Tibetan Plateau excimer laser in situ keratomileusis ( LASlK ) for myopia overcorrection.METHODS: The relevant information, 32 cases ( 58 eyes) in 126 cases (252 eyes) had obvious overcorrection after LASlK were analyzed.RESULTS: Two months after surgery, 32 cases ( 58 eyes) overcorrection (23. 0%), uncorrected visual acuity of 0. 5 ~0. 8, overcorrection range of +1. 50 ~ +2. 25DS, subjective inserts were ≥ 1. 0; Five case ( 7 eyes ) overcorrection 6mo after surgery (2. 8%), uncorrected visual acuity 0. 8~1. 0-2 , overcorrection range is +0. 75 ~+1. 25DS, subjective inserts were≥1. 0. Corneal thickness of overcorrection was 500~563μm, preoperative refraction was -5. 00 ~ -7. 50D, astigmatism -1. 50 ~ -2. 75DC, preoperative best corrected visual acuity ≥1. 0.CONCLUSlON: Overcorrection and long recovery time after LASlK in Tibet, possibly with local factors altitude, temperature, humidity, surgical parameters and situation.
ABSTRACT
<p><b>OBJECTIVE</b>By studying the mode and morphologic character of high fall injuries on the scene, and exploring the injury situation of different heights, different fall ways and postures, to provide a reference for the forensic identification of high fall injury.</p><p><b>METHODS</b>All the high fall cases were statistically analysed according to their gender, age, ground-touching posture, fall height, site and type of the injury.</p><p><b>RESULTS</b>Among 134 high fall cases, 98 were male and 36 were female with the age ranging from 2-71 years (37.6+/-16.9 on average), in which, 10-60 years old group consisted of 110 cases (82%). Most cases fell from windows or roofs (73%) and the touching objects were cement ground or shaft bottom of elevators. Among these cases, head injury was generally serious, followed by chest and abdominal injuries. The morphologic changes depend upon the height, nature, as well as the posture at the point while the body touches the ground.</p><p><b>CONCLUSION</b>Morphologic study of high fall injury assists medicolegal physicians to make correct identifications of the cause and nature of high fall injuries.</p>

<p><b>OBJECTIVE</b>To study the patterns and morphologic characteristics of blunt head injury and analyse its formative mechanism in attempt to provide references for medicolegal expertise.</p><p><b>METHODS</b>The statistical analysis was done in terms of gender, age, as well as the nature, pattern, location, and feature of the injuries.</p><p><b>RESULTS</b>Among the 202 cases of head injury-induced death, 124 were male and 78 female with the age ranging from 1-81 years. Death caused by homicide was dominant (106, 52.5%), followed by suicide (49, 24.3%) and accident (44, 21.8%). The majority of suicide-induced death were by falling from height, and traffic crash was responsible for majority of unexpected death cases. The morphology and pathogenesis of the injuries varied according to differences on the mode, magnitude, and orientation of the outside force giving rise to blunt injury as well as the character of vulnerants.</p><p><b>CONCLUSION</b>Studies on the morphology and its formative rationale of blunt head injury will offer easy access to medicolegal expertise on the mode and character of the injury.</p>
