To describe and explore the distribution of ocular biometric parameters of adult cataract patients in rural China.<jats:italic>Methods<\/jats:italic>. Three Lifeline Express Hospital Eye-Train missions of Peking University People\u2019s Hospital in China were chosen. 3828 adult cataract patients aged 29 to 88 years with axial length (AL) less than 27.0\u2009mm were enrolled.

Our study provides normative ocular biometry in a large, representative rural Chinese population. The AL is normally distributed with a positive skew and big kurtosis. The corneal powers are not normal distribution. The corneal astigmatism might have a significant effect on the visual acuity.<\/jats:p>","DOI":"10.1155\/2015\/171564","type":"journal-article","created":{"date-parts":[[2015,10,5]],"date-time":"2015-10-05T21:02:47Z","timestamp":1444078967000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["The Ocular Biometry of Adult Cataract Patients on Lifeline Express Hospital Eye-Train in Rural China"],"prefix":"10.1155","volume":"2015","author":[{"given":"Xiaoguang","family":"Cao","sequence":"first","affiliation":[{"name":"Peking University People\u2019s Hospital, Ophthalmology Department, Key Laboratory of Vision Loss and Restoration, Ministry of Education, Beijing Key Laboratory for the Diagnosis and Treatment of Retinal and Choroid Diseases, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianru","family":"Hou","sequence":"additional","affiliation":[{"name":"Peking University People\u2019s Hospital, Ophthalmology Department, Key Laboratory of Vision Loss and Restoration, Ministry of Education, Beijing Key Laboratory for the Diagnosis and Treatment of Retinal and Choroid Diseases, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongzhen","family":"Bao","sequence":"additional","affiliation":[{"name":"Peking University People\u2019s Hospital, Ophthalmology Department, Key Laboratory of Vision Loss and Restoration, Ministry of Education, Beijing Key Laboratory for the Diagnosis and Treatment of Retinal and Choroid Diseases, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"2","year":"2012"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.126.7.929"},{"issue":"1","key":"4","first-page":"73","volume":"42","year":"2001","journal-title":"Investigative Ophthalmology and Visual Science"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1159\/000308676"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0420.2000.078002177.x"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.09-3553"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.05-0435"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2008.144477"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.10-7148"},{"key":"11","year":"2010"},{"key":"12","year":"2010"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0420.2006.00847.x"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2009.07.028"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-198707000-00001"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-199103000-00008"}],"container-title":["Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2015\/171564.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2015\/171564.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2015\/171564.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T13:35:56Z","timestamp":1471527356000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/joph\/2015\/171564\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":15,"alternative-id":["171564","171564"],"URL":"https:\/\/doi.org\/10.1155\/2015\/171564","relation":{},"ISSN":["2090-004X","2090-0058"],"issn-type":[{"value":"2090-004X","type":"print"},{"value":"2090-0058","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
