Aims: To study the intraoperative complications in small incision cataract surgery and its management and to study the visual outcome following the management of intraoperative complications. Material and Methods: A total of 250 cases studied from who underwent SICS. Intraoperative complications were studied and managed. Visual outcome following these complications were studied by noting the best corrected visual acuity after day 1, 1st week, 3 rd week, 6th week following surgery. Results: The total intraoperative complications were seen in 22 (8.8%) patients. Posterior capsule rent was seen in 6 eyes (2.4%). Iris prolapse in 5 eyes (2%). Descemet detachment was seen in 3 eyes (1.2%). Premature entry was seen in 3 eyes (1.2%). Capsulorrhexis extension was seen in 2 eyes (0.8%). Zonular dialysis was seen in 2 eyes (0.8%). Superior iridodialysis was seen in only one eye (0.4%). Out of 250 cases, 246 came for follow up till 6th week. 214 (85.6%) patients had post operative BCVA 6/6 at the end of 6 th week, 25(10%) patients had 6/9, 5 patients (2%) had 6/12-6/18 and remaining 2 patients (0.8%) had 6/24-6/36 BCVA. Conclusion: The study results shows that in high quality cataract surgery (91.2% without intraoperative complications) 99% BCVA 6/18 or better can be attained. In our study incidence of intraoperative complications was 8.8% in which posterior capsular rent and iris prolapse were the common intraoperative complications.

Purpose To obtain age-specific data on changes in the prevalence and management of optically correctable visual impairments (OCVIs) in Ponza, Italy. Methods Ophthalmologic examinations were carried out to 1000 Ponzans aged 40-87 years in 1988 and to 836 persons in 2000. Visual acuity (VA) was evaluated under uncorrected (VA UC ), presenting (VA PR ), and best-corrected (VA BC ) conditions. We calculated the prevalence of total OCVIs (subjects with VA UC 40.5 logMAR and VA BC p0.5 logMAR in the better eye), uncorrected OCVIs (VA PR 40.5 logMAR), and corrected OCVIs (VA PR p0.5 logMAR) as well as the OCVI correction rate ((corrected OCVI/ total OCVI) Â 100). Subjects with uncorrected OCVIs were compared to those with corrected OCVIs to evaluate possible associations with some risk factors. Results Among 52-to 63-year olds there were increases in the prevalence of total OCVI (from 15.7 to 22.7%, P ¼ 0.051), corrected OCVI (from 10.9 to 19.9%, P ¼ 0.005), and OCVI correction rate (from 69.2 to 87.8%, P ¼ 0.045). Among 64-to 75-year olds decreases were observed in the prevalence of total OCVI (from 28.5 to 20.0%, P ¼ 0.029) and uncorrected OCVI (from 12.6 to 4.8%, P ¼ 0.003) while the OCVI correction rate increased from 55.9 to 76.1% (P ¼ 0.033). The overall prevalence of uncorrected OCVIs dropped from 7.5 to 4.1%. In 2000, uncorrected OCVI was associated with limited education, very advanced age, retirement, and refractive error associated with eye diseases. ConclusionsRefractive error management has improved in Ponza since 1988, and these changes may be, in part, due to higher education levels, increased frequency of cataract surgery, and slower progression of cataract-related disability.

“…Childhood cataracts are a major cause of visual impairment and blindness throughout the world, 1 and represent an important problem in paediatric ophthalmology. It has been estimated that almost three children of every 10 000 born in the United Kingdom each year will have congenital or infantile cataracts.…”

Purpose We reviewed all children presenting with microcephaly and bilateral congenital cataract in our paediatric cataract clinic, to identify their underlying diagnosis and clinical features that could help in early diagnosis of such conditions. Methods We screened our cataract database to collect data on all children presenting to our institute with cataract before 1 year of age for a period of 5 years (1997)(1998)(1999)(2000)(2001) inclusive. We found 166 cases of cataract, of which 85 were bilateral. Of the 85 children with bilateral cataract, five also had microcephaly. The case notes of these five children were retrospectively reviewed for age at presentation, ocular and systemic examination findings, results of electro diagnostic testing, outcome of cataract surgery, and any additional investigation results. Results In our series, three children were diagnosed with early-onset Cockayne syndrome (CS2), one was diagnosed with Micro syndrome and one with HallermannStreiff syndrome. Electrodiagnostic testing was abnormal in four of the five cases, and growth failure was present in all five. There was a good outcome from surgery in the three children with CS2 and the child with Hallermann-Strieff. There was a poor outcome in the child with Micro syndrome. Conclusions The presence of microcephaly in children presenting with bilateral cataracts in infancy is strongly suggestive of a syndromic cause. Early-onset Cockayne syndrome was the commonest underlying diagnosis in our series, but clinicians should be aware of other possibilities, and we discuss the differential diagnosis. Head circumference should be checked routinely in children with congenital cataract.
