“PURPOSE: To compare anterior segment parameters between 1-piece and 3-piece acrylic foldable intraocular lenses (IOLs).

SETTING: Farabi Eye Hospital, Tehran, Iran.

DESIGN: Prospective randomized comparative case series.

METHOD: Eyes scheduled for phacoemulsification were randomized into 2 equal groups to receive a 1-piece (AcrySof SA60AT) or 3-piece (AcrySof

MA60AC) foldable acrylic IOL. Scheimpflug imaging (Pentacam) was used to measure anterior segment parameters, including anterior chamber depth (ACD), anterior chamber angle (ACA), and anterior chamber volume (ACV), preoperatively and 1 week and 3 months postoperatively.

RESULTS: The study evaluated 125 eyes (123 patients). There was a statistically significant postoperative increase in ACD, ACA, and ACV at 1 week and 3 months in both IOL groups. Although the mean ACD was significantly

higher in the 3-piece group at 1 week, there was no significant between-group difference in ACD, ACA, or ACV at 3 months. There was no significant change in anterior segment parameters from 1 week to 3 months in the 1-piece group; however, the 3-piece group had statistically significant decreases in ACD, ACA, and ACV. Refraction remained stable throughout the follow-up in the 1-piece group but showed a significant myopic shift from 1 week to 3 months in the 3-piece group.

CONCLUSIONS: After phacoemulsification, the 1-piece acrylic foldable

IOL showed little axial movement and provided stable refraction throughout the follow-up. The 3-piece IOL had www.selleckchem.com/products/pf-562271.html significant forward selleck screening library movement and led to a myopic shift within 3 months postoperatively. Results indicate that spectacles can be prescribed earlier in eyes with a 1-piece IOL.”
“Background: Oral health-related quality of life (OHRQoL) in children and adolescents with signs and symptoms of temporomandibular disorder (TMD) has not yet been measured. This study aimed to evaluate the validity and reliability of OHRQoL measure for use in children and preadolescents with signs and symptoms of TMD.

Methods: Five hundred and forty-seven students aged 8-14 years were recruited from public schools in Piracicaba, Brazil. Self-perceptions of QoL were measured using the Brazilian Portuguese versions of Child Perceptions Questionnaires (CPQ)(8-10) (n = 247) and CPQ(11-14) (n = 300). A single examiner, trained and calibrated for diagnosis according to the Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD), examined the participants. A self-report questionnaire assessed subjective symptoms of TMD. Intraexaminer reliability was assessed for the RDC/TMD clinical examinations using Cohen’s Kappa (kappa) and intraclass correlation coefficient (ICC). Criterion validity was calculated using the Spearman’s correlation, construct validity using the Spearman’s correlation and the Mann-Whitney test, and the magnitude of the difference between groups using effect size (ES).
