AIM: To investigate and evaluate the prevalence of xerophthalmia among aerospace science and technology staff and its influencing factors for the eye health guidance.METHODS: The staff underwent physical examination in our examination center from September 2013 to June 2014 were preliminary screened, and those patients with symptoms of dry eye were investigated with questionnaires and diagnosed by basic lacrimal secretion test (Schirmer I), breakup time of tear film (BUT)test and fluorescein (FL) staining test.RESULTS: There were 606 complaints of dry eye symptoms of the 1 000 premiers, distributed in random (60.6%), and 432 employees were diagnosed (43.2%). The positive rate of dry eye was 71.3%. The causes of xerophthalmia, besides of gender, age, also include a variety of factors such as air-conditioner, heating, video terminals, sleep time, etc.CONCLUSION: Dry eye, an epidemic disease, has a variety of symptoms and complex etiology, the main causes of aerospace science and technology staff with dry eye is working environment and some local factors. We can give appropriate health guidance according to the different factors. Meanwhile the relevant series of dry eye screening should also be taken as a routine examination in ophthalmic examination. ©, 2014, International Journal of Ophthalmology (c/o Editorial Office).

AIM: To compare the effect of different incision in corneal astigmatism after phacoemulsification.METHODS: Totally 88 cases (122 eyes) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases (62 eyes) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism (SIA), uncorrected visual acuity (UCVA) and best correct vision acuity (BCVA) were observed in pre-and post-operation at 1 d; 1 wk; 1 mo.RESULTS: The mean astigmatism had statistically significant difference between two groups at 1 d; 1 wk; 1mo after operation (P〈0.05). The SIA had statistically significant difference at 1 d (P〈0.05); The SIA had no statistically significant difference between two groups at 1mo after operation (P〉0.05). UCVA≥0.5 and BCVA≥0.8 had statistically significant difference at 1 d; 1 wk (P〈0.05). There had no statistically significant difference at 1mo after operation (P〉0.05).CONCLUSION: Phacoemulsification with scleral tunnel incision remove combined intraocular lens (IOL) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial. ©, 2014, International Journal of Ophthalmology (c/o Editorial Office). All right reserved.
