Anisometropia and its correction in children in northwest China: A study based on autorefraction data.

Background: To investigate the prevalence and correction of anisometropia among primary school children in northwestern China.

Methods: A cross-sectional school-based study was conducted in Shaanxi Province. Visual acuity (VA) and autorefraction without cycloplegia were assessed in all participants, and some received axial length (AL) measurements.

[The clinical results of femtosecond laser-assisted deep anterior lamellar keratoplasty in patients with keratoconus].

Objective: To evaluate the clinical results and safety of deep anterior lamellar keratoplasty (DALK) in patients with keratoconus assisted by a femtosecond laser.

Methods: Six eyes of 5 patients with keratoconus underwent DALK procedures by using a femtosecond laser. The mean thinnest corneal thickness, evaluated with ultrasound and measurement of visual acuity by using the standard logarithm visual chart.
