Abstract
Realizing that precise posterior chamber intraocular lens (PC-IOL) centration is needed to consistently achieve good optical results and visual rehabilitation after modern cataract surgery, the authors assessed the status and success rate of lens haptic fixation and its correlation with lens optic centration-decentration in a large series of eyes with PC-IOLs obtained postmortem.

Asymmetrically fixed lenses consistently showed significant decentration. During the past 5 years (1993-98), the overall rate of in-the-bag fixation increased to 59.2%; by 1998 it had increased to 64%. Most significantly, success in achieving bag-bag fixation of foldable IOLs implanted in association with modern capsular surgery with small incisions has surged to 90% over the past 4 years.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">The authors found a direct correlation of decentration in eyes with asymmetric fixation, and the results underscore the need for careful in-the-bag haptic placement. Although few surgeons today would dispute the goal to implanting haptics in the capsular bag, these findings show that the overall success rate over the years has, while improving, remained surprisingly low. The overall success rate of about 60% seen with all lens designs is probably as good as can be expected with classic large-incision extracapsular techniques. However, and most important and encouraging, the success rate of haptic fixation in cases with foldable lenses has improved dramatically during the past 4 years (up to the 90% range). This coincides with the present emphasis on modern capsular surgery and small-incision techniques used to insert these lenses.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Ram</LastName><ForeName>J</ForeName><Initials>J</Initials><AffiliationInfo><Affiliation>Post-Graduate Institute of Medical Education & Research, Chandigarh, India.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Apple</LastName><ForeName>D J</ForeName><Initials>DJ</Initials></Author><Author ValidYN="Y"><LastName>Peng</LastName><ForeName>Q</ForeName><Initials>Q</Initials></Author><Author ValidYN="Y"><LastName>Visessook</LastName><ForeName>N</ForeName><Initials>N</Initials></Author><Author ValidYN="Y"><LastName>Auffarth</LastName><ForeName>G U</ForeName><Initials>GU</Initials></Author><Author ValidYN="Y"><LastName>Schoderbek</LastName><ForeName>R J</ForeName><Initials>RJ</Initials><Suffix>Jr</Suffix></Author><Author ValidYN="Y"><LastName>Ready</LastName><ForeName>E L</ForeName><Initials>EL</Initials></Author></AuthorList><Language>eng</Language><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>Ophthalmology</MedlineTA><NlmUniqueID>7802443</NlmUniqueID><ISSNLinking>0161-6420</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D000180">Acrylic Resins</NameOfSubstance></Chemical><Chemical><RegistryNumber>0</RegistryNumber><NameOfSubstance UI="D012826">Silicone Elastomers</NameOfSubstance></Chemical><Chemical><RegistryNumber>9011-14-7</RegistryNumber><NameOfSubstance UI="D019904">Polymethyl Methacrylate</NameOfSubstance></Chemical></ChemicalList><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000180">Acrylic Resins</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000368">Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005548">Foreign-Body Migration</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000209">etiology</QualifierName><QualifierName MajorTopicYN="Y" UI="Q000517">prevention & control</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D019654">Lens Implantation, Intraocular</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000379">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D007910">Lenses, Intraocular</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D019060">Minimally Invasive Surgical Procedures</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D019904">Polymethyl Methacrylate</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D011446">Prospective Studies</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D012826">Silicone Elastomers</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D013536">Suture Techniques</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000009">adverse effects</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014786">Vision Disorders</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000534">rehabilitation</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014792">Visual Acuity</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>1999</Year><Month>5</Month><Day>18</Day><Hour>5</Hour><Minute>24</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2001</Year><Month>3</Month><Day>28</Day><Hour>10</Hour><Minute>1</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>1999</Year><Month>5</Month><Day>18</Day><Hour>5</Hour><Minute>24</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">10328385</ArticleId><ArticleId IdType="pii">S0161-6420(99)00505-9</ArticleId><ArticleId IdType="doi">10.1016/S0161-6420(99)00505-9</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Inde</li></country></list><tree><noCountry><name sortKey="Apple, D J" sort="Apple, D J" uniqKey="Apple D" first="D J" last="Apple">D J Apple</name><name sortKey="Auffarth, G U" sort="Auffarth, G U" uniqKey="Auffarth G" first="G U" last="Auffarth">G U Auffarth</name><name sortKey="Peng, Q" sort="Peng, Q" uniqKey="Peng Q" first="Q" last="Peng">Q.
