objectives: this study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople’s judgment, and to determine whether there is any relationship between dental and smile esthetics. materials and methods: using the q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodo...

BACKGROUND This study aimed to determine and validate that use of a nomogram could enhance the predictability of small-incision lenticule extraction (SMILE) surgery. MATERIAL AND METHODS 195 eyes from 98 patients were enrolled in group 1, and 46 eyes from 26 patients in group 2. Uncorrected and corrected distance visual acuity (UDVA and CDVA), manifest refraction spherical equivalent (SE) preop...

OBJECTIVES To evaluate two-year results of small-incision lenticule extraction (SMILE) for correction of high myopia. MATERIALS AND METHODS Forty-five eyes of 35 patients with mean spherical equivalent (SE) of -7.10±0.95 D who underwent routine SMILE by a single surgeon and were followed for at least 2 years were analyzed by retrospective chart review. SMILE was performed with a Visumax femto...

BACKGROUND To investigate accommodative response and accommodative lag changes after femtosecond laser small incision lenticule extraction (SMILE) for moderate to high myopia correction. METHODS A total of 32 eyes of 32 patients with no strabismus who underwent SMILE were enrolled in this prospective clinical study. The accommodative response was obtained viewing monocularly with spherical eq...

Smile line is one of the most important element of the smile esthetics. In an attractive smile, the maxillary anterior incisal curve is parallel to the lower lip. With the changes in face, lips and teeth muscles, which are caused by aging, this element (smile line) also changes. Aging causes smile line to move from its parallel position and in complete smile, formulate different shapes relative...

Abstract Background The refractive surgeries induce corneal higher order aberrations (C-HOAs). In this study, change of C-HOAs after small-incision lenticule extraction (SMILE) compared to femtosecond assisted laser in situ keratomileusis (femto-LASIK), and photorefractive keratectomy with mitomycin-C (PRK) under photopic mesopic conditions. Methods prospective age, gender, apical thickness (AC...
