Abstract?AlM: To evaluate the difference of contrast sensitivity ( CS) in photopic and scotopic environments in eyes with myopia and myopic astigmatism operated with femtosecond laser in situ keratomileusis ( femto-LASlK ) and laser in situ keratomileusis ( LASlK) .?METHODS: ln a prospective study 160 myopia and myopic astigmatism patients' eyes were involved, which accepted femto- LASlK or LASlK in our hospital from January 2010 to February 2012. The myopia degree was -1. 50 ~ -10. 00D, the astigmatism degree ≤-6. 0D. Eighty eyes were treated with femto-LASlK in group A, and 80 eyes were treated with LASlK in group B, All patients in the treatment group completed the final 6mo of follow-up. The uncorrected visual acuity ( UCVA) and the best spectacle-corrected visual acuity ( BSCVA) , objective and manifest refractions, results of slit-lamp examination, the side effects, intraocular pressure, corneal topography, CS in photopic and scotopic environments were noted.? RESULTS: All of operations on 160 cases were successful without severe complication after 6 mo follow-up. CS of femto-LASlK group ( group A) at each spatial frequency environment were higher than that of LASlK group (group B). ln group A, after 1mo the photopic CS, after 3mo of scotopic CS recovered to the preoperative level, 6mo after surgery improved than before the operation. ln group B, after 3mo photopic CS to the preoperative level, scotopic CS at 6mo after operation was still not recovered to the preoperative level.?CONCLUSlON:Femto-LASlK for correction of myopia and myopic astigmatism, in improving the postoperative contrast sensitivity under shade environment has more advantages than LASlK.

OBJECTIVETo explore significance of preoperative color Doppler flow imaging (CDFI) for screening deep vein thrombosis in upper limbs fracture.

METHODSFrom January 2009 to December 2011, 1200 patients with upper limb fracture caused by trauma were respectively analyzed. There were 833 males and 367 females,ranging from 20 to 78 (mean 41.94 +/- 15.41) years. All patients had swelling and pain in injured limbs when enrolled. CDFI was used to examine upper limbs vein at 3 to 10 d after improvement of swelling, 1 day before reduction. Relationship among occurrence of thrombosis, gender, age and fracture sites were analyzed. Patients with DVT were analyzed with respective study to decide whether combined with diabetes, hypertension and hyperlipidemia.

RESULTSAll patients were checked by CDFI,which confirmed 9 cases with DVT. The rate of thrombosis was 0.75%, women than men (P < 0.01). The risk of blood clots occurred over 30 years, and the occurrence of thrombosis in humerus fracture was higher than radius ulnar fracture. One of 9 patients combined with hypertension and hyperlipidemia, 1 case combined with diabetes, and 7 cases with no complication.

CONCLUSIONUpper trauma fracture may occur deep vein thrombosis; CDFI should be used to check DVT in qualified hospital,which can maintain medical safety,decrease occurrence of medical disputes, and ganrantee patient's safety.

AIM: To compare the measurement of anterior chamber depth(ACD) inclusive of corneal thickness using intrao-cular lens(IOL) master and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method.METHODS: Two consecutive measurements of ACD were prospectively performed using IOL master and UBM in 60 eyes in 60 individuals. Mean values were compared using the paired t test. For each individual, ACD measure-ments was performed 5 times to estimate the repeatability of each method by a coefficient of variation(CV).RESULTS: The mean ACD was 2.95±0.25mm with the IOL master and 2.96±0.22mm with the UBM. This diffe-rence was not statistically significant (P=0.631).The coefficient of variation (CV) was 0.56%±0.26% and 0.65%± 0.36% in IOL master and UBM, respectively.CONCLUSION: The mean ACD of IOL master was the same as UBM. The repeatability of IOL master is better than UBM.
