Reliability and validity of the Japanese version of the Ocular pain assessment survey (OPAS-J).

This study aimed to determine the reliability and validity of the Japanese version of the Ocular Pain Assessment Survey (OPAS-J) to measure ocular pain and quality of life. A multi-institutional cross-sectional study was conducted on participants with and without ocular pain. The Wong-Baker FACES® Pain Rating Scale served as the gold standard for measuring the intensity of ocular pain.

Demodex-Mite Infestation in Cilia and its Association With Ocular Surface Parameters in Japanese Volunteers.

Objectives: To investigate the presence of Demodex mites on the eyelashes of a Japanese population and to explore its associations with subjective ocular symptoms and clinical ocular surface signs, including lid margin findings and fluorescein breakup time (FBUT).

Methods: Sixty-three Japanese Tokyo-based volunteers were examined (24 men and 39 women; mean±SD of age, 50.6±15.

Impact of Corneal Higher-Order Aberrations on Visual Acuity After Deep Anterior Lamellar Keratoplasty in Treating Keratoconus.

Purpose: To evaluate the incidence of the Descemet membrane (DM) folds after deep anterior lamellar keratoplasty (DALK) in treating keratoconus. We also evaluated the influence of DM folds and corneal higher-order aberrations (HOAs) on visual acuity after DALK.

Methods: This retrospective study included 89 consecutive eyes of 87 patients who underwent DALK for the treatment of keratoconus at Tokyo Dental College Ichikawa General Hospital from April 2002 to June 2017.
