To evaluate the efficacy and safety of limbal relaxing incision ( LRl) for correcting corneal astigmatism during implantable collamer lens ( lCL) surgery.METHODS:A total of 185 eyes of 105 patients with high myopia and corneal keratometric astigmatism were included in the study. lCL surgery with concomitant relaxing incision was performed in 105 eyes of 60 patients in LRls group ( Group A) . Eighty eyes of 45 patients only underwent lCL surgery were in control group ( Group B) . All patients undergone ophthalmic examination that included uncorrected visual acuity ( UCVA ) , best -corrected visual acuity ( BCVA ) , Pentacam analysis system to observe the changes of corneal astigmatism before and 1wk, 1 and 3mo after surgery.RESULTS: Respectively comparing UCVA between two groups in 1 and 3mo postoperatively, the P values were considered statistically significant ( P < 0. 05 ). But, respectively comparing BCVA between two groups in 1wk, 1 and 3mo postoperatively, the P values were considered no statistically significant ( P > 0. 05 ). Preoperative corneal astigmatism was 1. 52 ± 0. 55D in group A and 1. 48 ± 0. 57D in group B, there was no statistically significant difference (P>0. 05). One week postoperatively, the astigmatism was 0. 55 ± 0. 41D in group A and 1. 20 ± 0. 48D in group B. One month postoperatively, the astigmatism was 0. 60 ± 0. 38D in group A and 0. 93 ± 0. 47D. Three months postoperatively, the astigmatism was 0. 51 ± 0. 32D in group A and 0. 96 ± 0. 40D in group B. The difference between the two groups were statistically significant ( P<0. 05 ). The difference value of corned astigmatism before surgery and 1wk, 1 and 3mo after surgery had statistical significance ( P<0. 05). ln LRls group, at preoperative and postoperative time points, the average corneal astigmatism changes were also considered statistically significant difference (P<0. 05). CONCLUSlON: LRls performed during lCL surgery appeared to be an effective and safer procedure to reduce pre-existing corneal astigmatism and improve UCVA as well as the visual quality.

Objective To evaluate the feasibility of using a microsensor motion capture unit (MCU) to assess the reaching characteristics of hemiplegic stroke patients. Methods Twenty-three hemiplegic stroke patients with an average age of (61 ± 11) years and ten normal subjects of matching age were asked to sit on a chair and use the affected arm (for the patients) or the right arm (for the normal subjects) to reach for a cup on a table just in front of the shoulder at arm's length away.Four small sensor boxes which could detect movement and its speed and smoothness in three dimensions were fixed to the subject's spine,upper arm,forearm and hand.The test was repeated four times after two trial runs.The average velocity,peak velocity,degree of joint dispersion,entropy of acceleration,joint coordination and active range of motion ( AROM ) of the shoulder were analyzed.The patients and normal subjects were statistically compared.The results were correlated with Fugl-Meyer upper extremity scores using Spearman correlation analysis. Results All of the measured variables showed significant differences between the patients and normal subjects.In the correlation study,the average velocity,peak velocity,AROM of the shoulder and joint coordination showed significant correlation with the Fugl-Meyer scores.There was,however,no significant correlation between degree of dispersion of the shoulder or elbow joints or the entropy of acceleration ( which represented the quality of movement) and Fugl-Meyer upper extremity scores. Conclusions The results suggest that microsensor MCUs can quantitatively assess the kinematics of reaching among hemiplegic stroke patients.They can provide valuable and objective data about the functional quality of multiple joint movements in three dimensions.
