There are eight main components assessed smile, two which the arc gingiva display. Both have received lot attention because they known major influence on smile.The harmony gingival display will produce smile....

PURPOSE To characterize the early ocular-surface changes or tear inflammatory-mediators levels following small-incision lenticule extraction (ReLEx smile) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS Forty-seven myopic subjects were recruited for this prospective study. Fifteen underwent ReLEx smile and thirty-two underwent FS-LASIK. Corneal fluorescein (FL)...

Questioned by Hyub-Soo Lee Private Practice, Daejeon, Korea A1. In the past literature review, the relationship between smile esthetic variables and malocclusion lacked solid and sufficient evidence, therefore it aroused our interest to design a study of analyzing smile characteristics in different malocclusions. In our study, we found that arc ratio, upper teeth number showing, upper lip heigh...

This study aimed at evaluating the effect of intraoperative corneal pocket irrigation in small incision lenticule extraction (SMILE) and compares it to that in femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Sixteen rabbit eyes underwent a SMILE procedure, with 8 eyes having corneal pocket irrigation, while the other 8 eyes were without irrigation. Another 16 eyes underwent a FS-L...

To evaluate the refractive outcomes of balanced salt solution infiltration during small-incision lenticule extraction (SMILE).This randomized prospective study enrolled 52 patients (104 eyes) with myopic astigmatism. Patients underwent SMILE to correct the myopic astigmatism in Daping Hospital of the Third Military Medical University between January and July 2013. One eye of each patient receiv...

The objective of the present study was to assess smile aesthetics after orthodontic treatment in subjects with and without the extraction of four first premolars. Post-treatment coloured frontal photographs (4 × 6 inches) of 60 Pakistani subjects, 21 males and 39 females, aged between 15 and 30 years were assessed by one examiner. For 50 per cent (n = 30) of the patients, treatment included the...

Facial expression recognition is one of the most challenging research area in the image recognition field and has been studied actively for a long time. Especially, we think that smile is important facial expression to communicate well between human beings and also between human and machines. Therefore, if we can detect smile and also estimate its intensity at low calculation cost and high accu...

Purpose: To compare visual outcome between Femtosecond LASIK and ReLEx SMILE in treatment of Myopia. Method: A single center prospectiverandomized clinical study in which patientswith Myopia +/-astigmatism were allocated to FemtoLASIK or SMILE group with 50 patients in each group. Main outcome measures were Visual acuity, safety and efficacy index; Contrast sensitivity; Aberrations; post-operat...
