A total of 31 female subjects (62 eyes) with eyeliner tattoos who visited the outpatient department of Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University from April to September 2022 due to visual fatigue and other reasons were included as the eyeliner group, and 28 age-matched female subjects (56 eyes) without eyeliner tattoos were included as the control group. Questionnaires, tear meniscus height measurement, evaluation of the distance between meibomian gland imaging and the eyeliner, detection of the thickness of the lipid layer of the tear film and blink parameters, tear secretion test and tear film break-up time(BUT) measurement, meibomian gland function score and other examinations were carried out for all subjects. The main indicators included the Ocular Surface Disease Index (OSDI) score, tear meniscus height (TMH), lipid layer thickness of the tear film, tear secretion test, and BUT, etc. <b>Results:</b> The OSDI score of the eyeliner group was (43.05±19.00) points, which was significantly higher than that of the control group [(20.70±12.42) points] (<i>P</i><0.05).

Clinical data were collected from 10 patients (20 eyes) with high myopia and monocular cataract who underwent phacoemulsification cataract extraction and intraocular lens implantation in the cataract eye (cataract surgery eye), and implantable Collamer lens (ICL) implantation in the contralateral eye (ICL implantation eye) at the Ophthalmology Department of the Army Characteristic Medical Center from June 2021 to December 2023. Among them, there were 4 males and 6 females, with an average age of (35.60±7.62) years. Uncorrected visual acuity was measured using the international standard visual acuity chart, and spherical equivalent (SE) and best corrected visual acuity (BCVA) were obtained through comprehensive optometry. Visual acuity was recorded in the form of logarithm of the minimum angle of resolution (logMAR). Objective visual quality parameters were obtained using a visual quality analysis system, and subjective visual quality was obtained through questionnaire surveys.
