Many developing countries now use extracapsular cataract extraction (ECCE) with intra-ocular lens insertion (IOL) in their cataract blindness-prevention programmes. To date, little research has been directed at visual outcomes and complication rates of ECCE/IOL surgery in developing countries.Methods: We conducted a follow-up study of 155 eyes approximately 12 months after ECCE/IOL surgery by eight local eye surgeons in Central Vietnam. We report the findings for the 144 eyes (93%) successfully reviewed. All subjects underwent manual ECCE with insertion of a three-piece posterior chamber IOL. All eyes were also assessed for the presence and severity of posterior capsule opacification (PCO) using a newly developed grading system.Results: Overall, 110 eyes (75%) had uncorrected visual acuities > or = 6/24 and 107 eyes (74%) had best spherically corrected visual acuities > or = 6/18. Some degree of PCO was found in 40% of eyes, but was graded as visually significant in only 4% of eyes. No major sight-threatening complications were noted. A portable neodymium:yttrium aluminium garnet (Nd:YAG) laser was used to perform capsulotomies on all eyes with visually significant PCO. There were no laser complications noted.Conclusions: At approximately 1 year after ECCE/IOL, the visual outcomes for subjects in this cohort were favourable and complication rates were low. Posterior chamber opacification was not a major cause of vision impairment in this cohort. Portable Nd:YAG lasers may provide an effective solution to the problem of visually significant PCO occurring in developing countries as a late complication of extracapsular surgery. These findings support an increasing role for ECCE/PCIOL surgery by trained local eye surgeons in developing countries.","PeriodicalId":8596,"journal":{"name":"Australian and New Zealand journal of ophthalmology","volume":"26 1","pages":"13-7"},"PeriodicalIF":0.0,"publicationDate":"1998-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20447459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, IOP fell to roughly equal degrees (mean IOP being 14 mmHg at 3 months; P = 0.84). At 12 months, IOP in the phacotrab group was slightly lower than that in the ECCE-trab group (13.4+/-4.3 vs 15.4+/-4.4 mmHg, respectively; P = 0.0312). The number of pre-operative medications did not appear to affect outcome (P = 0.124). Visual recovery was approximately 3 months faster in the phaco-trab group. By 12 months there was little difference in visual acuity, with an average improvement of two Snellen lines (P = 0.68). The mean change in astigmatism was significantly less in the phaco-trab group (0.61+/-1.25 vs 1.39+/-1.46 D, respectively, P = 0.0063). Transient hypotony (IOP < 5 mmHg) was more frequent in the phaco-trab group (66 vs 32%, respectively; P < 0.002). The frequency of other complications was not significantly different between the two groups.Conclusion: Both ECCE-trab and phaco-trab procedures are safe and effective. However, the phaco-trab procedure may have slightly improved IOP control, earlier visual recovery and less astigmatism.","PeriodicalId":8596,"journal":{"name":"Australian and New Zealand journal of ophthalmology","volume":"26 1","pages":"19-27"},"PeriodicalIF":0.0,"publicationDate":"1998-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20447460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proximal part of the muscle was not found. The distal part of the snapped muscle was excised for pathological examination. Transposition of the inferior halves of the adjacent horizontal muscles to the insertion of the inferior rectus (a modified inverse-Knapp procedure) was performed in all cases.Results: After the transposition surgery, one patient was orthotropic in the primary position, one patient required a prism correction to produce a range of single vision and the third patient was orthotropic after a further operation. There was good depression in one case and the other two had a limitation of depression. In all cases, horizontal movements remained intact and there were no signs of anterior segment ischaemia.Conclusions: The unique relations of the inferior rectus to the surrounding tissues may be a factor in causing the breaking of this muscle. Two of the patients were elderly and this may be a factor also. Transposition surgery is the appropriate management when the proximal part of the snapped muscle cannot be located and has satisfactory but imperfect results.","PeriodicalId":8596,"journal":{"name":"Australian and New Zealand journal of ophthalmology","volume":"26 1","pages":"29-35"},"PeriodicalIF":0.0,"publicationDate":"1998-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20447461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
