Differences between the predicted and actual postoperative refraction were then analyzed for each formula.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">In practice, 55% of patients were within +/-1.0 D of the refraction predicted by their surgeon. In theory, the Haigis formula would have given the smallest mean refractive error (+0.51 +/- 0.12 D), followed by the Hoffer Q (-0.70 +/- 0.14 D), Holladay 1 (-1.11 +/- 0.13 D), and SRK/T formulae (-1.45 +/- 0.14 D). The Haigis formula overpredicted the lens power required, which would have generated a myopic result. The other formulae underpredicted the lens power required and would have generated a hyperopic result. There was a significant difference between lens designs: the Haigis was more accurate for open-loop, whereas the Hoffer Q was more accurate for plate-haptic lenses. The anterior chamber depth measurement could also be used to predict changes in intraocular pressure after surgery.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">This represents the largest published series to date of biometry predictions for cataract surgery in extreme hyperopia and confirms the Haigis formula to be the most accurate. A consistent difference between open-loop and plate-haptic lenses suggests that haptic design may influence the effective lens position in very small eyes. We further propose a simple formula to optimize the Haigis and Hoffer Q formulae in patients with extreme hyperopia.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>MacLaren</LastName><ForeName>Robert E</ForeName><Initials>RE</Initials><AffiliationInfo><Affiliation>Moorfields Eye Hospital, City Road, London, United Kingdom. robert.maclaren@moorfields.nhs.uk</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Natkunarajah</LastName><ForeName>Mythili</ForeName><Initials>M</Initials></Author><Author ValidYN="Y"><LastName>Riaz</LastName><ForeName>Yasmin</ForeName><Initials>Y</Initials></Author><Author ValidYN="Y"><LastName>Bourne</LastName><ForeName>Rupert R A</ForeName><Initials>RR</Initials></Author><Author ValidYN="Y"><LastName>Restori</LastName><ForeName>Marie</ForeName><Initials>M</Initials></Author><Author ValidYN="Y"><LastName>Allan</LastName><ForeName>Bruce D S</ForeName><Initials>BD</Initials></Author></AuthorList><Language>eng</Language><GrantList CompleteYN="Y"><Grant><GrantID>G0601588</GrantID><Agency>Medical Research Council</Agency><Country>United Kingdom</Country></Grant></GrantList><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Am J Ophthalmol</MedlineTA><NlmUniqueID>0370500</NlmUniqueID><ISSNLinking>0002-9394</ISSNLinking></MedlineJournalInfo><CitationSubset>AIM</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000867">Anterior Chamber</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000033">anatomy & histology</QualifierName><QualifierName MajorTopicYN="N" UI="Q000736">ultrasonography</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D001699">Biometry</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D002387">Cataract Extraction</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D003315">Cornea</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000033">anatomy & histology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006956">Hyperopia</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D019654">Lens Implantation, Intraocular</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D007910">Lenses, Intraocular</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D008485">Medical Audit</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D008962">Models, Theoretical</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D017060">Patient Satisfaction</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D011184">Postoperative Period</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D012029">Refraction, Ocular</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D015203">Reproducibility of Results</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D012189">Retrospective Studies</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014792">Visual Acuity</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000502">physiology</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2006</Year><Month>6</Month><Day>27</Day></PubMedPubDate><PubMedPubDate PubStatus="revised"><Year>2007</Year><Month>2</Month><Day>11</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2007</Year><Month>2</Month><Day>14</Day></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2007</Year><Month>5</Month><Day>26</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2007</Year><Month>6</Month><Day>29</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2007</Year><Month>5</Month><Day>26</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pii">S0002-9394(07)00233-4</ArticleId><ArticleId IdType="doi">10.1016/j.ajo.2007.02.043</ArticleId><ArticleId IdType="pubmed">17524766</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
