Purpose: To determine the preoperative visual acuity of cataract patients over a 10-year period in a tertiary facility as a means of auditing the cataract surgical services. Methods: A retrospective study of patients with age-related cataracts who had cataract surgery performed between January 2007 and December 2016 at the University College Hospital, Ibadan. Systematic random sampling and probability proportionate to size were used to recruit a representative sample. Information on sociodemographic characteristics, preoperative visual acuity, ocular and systemic comorbidities were retrieved and analysed. Results: Of the 499 patients studied, males were 268 (53.7%) and their mean age was 67.69 (±9.51) years. The predominant visual acuity was hand motion 184 (36.9%) and yearly mean preoperative visual acuity was in the range of 0.0037–0.04 decimal. Conclusion: The mean preoperative visual acuity of patients in this facility did not change over the 10-year study period. Mean value of preoperative visual acuity remained within the range of blindness and did not improve over the decade. This could either be a reflection of visual impairment at which our patients seek care or an indication of the range of visual acuities at which surgeons are willing to offer cataract surgery in our environment. This trend has negative implications on the burden of cataract blindness as it reflects poor coverage of surgery for other levels of visual impairment due to cataract.

To evaluate the visual outcome in patients who have had their cataract surgery in a tertiary hospital of Chittagong district in Bangladesh. This is a clinic-based study of consecutive cataract-operated patients who had age-related cataract with vision less than <6/60 before surgery. A total of 228 patients who visited the hospital and met the eligibility criteria were included in the study. The mean age of the patients was 62.46± 10.14 years and 134 (58.8%) were female. A total of 456 surgeries were performed on 228 patients. The most common procedure was small incision cataract surgery (SICS) with intraocular lens (IOL) implantation, operated in 422(92.5%) eyes. Among cataract-operated eyes, 290 (64%) had presenting vision >6/18 and <6/60 were found in 11 (2.4%) eyes. In most of the cases, visual acuity has improved after best correction as the percentages with the best correction were 402(88%) and 7(1.55%) respectively. Analysis of multiple logistic regression shows that patient’s older age (OR 9.101; 95% CI 3.331, 24.869), gender female (OR 2.374 CI 1.403, 4.017), literacy (OR 1.660; CI 1.009, 2.733) and SICS surgery technique (OR 3.540; CI1.298, 9.659) were significantly associated with poor visual outcome. Overall, this study demonstrates that cataract surgery can restore good visual acuity. However, the visual outcome needs to be improved to meet the WHO standard, and more attention should be directed towards monitoring of outcomes and correction of refractive error after cataract surgery.

ObjectiveTo report the outcomes of cataract surgery performed by non-physician cataract surgeons due to lack of ophthalmologists in remote areas of North Cameroon.DesignProspective cohort study.SettingThe main centre of the non-governmental organisation Ophtalmo Sans Frontières in Lagdo.Participants and interventionsAge-related cataract surgery performed between 28 November 2016 and 17 May 2017.Main outcomes measuresThe main outcome measure was presenting visual acuity (PVA) 1–4 weeks after surgery, classified according to the WHO as good (PVA ≥6/18), borderline (PVA 6/60–6/18) and poor (PVA <6/60). The WHO definition of blindness (visual acuity <3/60) and severe visual acuity (visual acuity 3/60–6/60) was used to assess the proportion of patients with a change in WHO category.ResultsWe included 474 eyes of 474 patients; the mean (SD) age was 63.9 (15) years (42.2% female). At 1–4 weeks after surgery, the surgical outcome was good for 170 patients (41.1%), borderline for 213 (51.5%) and poor for 31 (7.5%). In all, 224 patients (47.2%) had blindness or severe visual impairment before cataract surgery and 22 (5.3%) at 1–4 weeks after surgery. Poor visual outcome was associated with older age (p=0.018), preoperative blindness or severe impairment (p=0.012) and surgical complications (p=0.019).ConclusionBlindness and severe visual impairment were significantly decreased in the early postoperative period. Poor outcomes were associated with older age, low preoperative binocular visual acuity and intraoperative complications. Non-physician cataract surgeons may compensate for the lack of ophthalmologists in remote areas of low-income and middle-income countries.

Background: In India the coverage and outcome of cataract management are through camps and hospital undertaking rural cataract surgical services. There are varied outcomes of cataract surgery in population based studies within our country while cataract surgical outcomes have inbuilt dependency on various factors. National program for control of blindness and visual impairment aims in improvement of vision of the cataract patients. Thus evaluating cataract outcome would help top strengthen the national program.Methods: The study was part of population based blindness survey carried out among 40 years and above rural population in Dhule district of Maharashtra during 2019. In the survey 2370 villagers, 40 years and above were surveyed for blindness prevalence by 30 Cluster sampling technique having 79 peoples from each cluster. Collection of baseline data with information of eye care services and ophthalmic examination was done.Results: Prevalence of cataract in 40 year and above population in study was 20.78%. In present study predominant barrier in cataract operation in 71.1% participants for not having consultation was belief it to be destiny or God’s will.  20.3% cataract patients with visual impairment had visual acuity of 6/60 and 18.4% had less than 3/60 visual acuity. Maximum participants had cataract operated in government hospital 61.7%. In the study cataract surgical coverage was 72.7% by eyes and 81.7% by person for visual acuity <3/60.Conclusions: Efforts to increase cataract surgical coverage would help to reduce the prevalence of visual impairment due to cataract.

AIM: To assess the patient-reported outcome of phacoemulsification with posterior chamber single focus foldable intraocular lens (SIOL) using the Chinese version of Catquest-8SF questionnaire (Catquest-8SF-CN), evaluate the applicability of Catquest-8SF scale in northern Chinese and its sensitivity to cataract surgery. METHODS: Prospective clinical case follow-up study. The patients were recruited from the Central Hospital of Tai’an and completed the Catquest-8SF questionnaire by face-to-face interviews before and 3mo after surgery at the hospital. RESULTS: A total of 120 cataract patients with median age 67.6y and 52.5% female completed the Catquest-8SF. The Cronbach’s α coefficient of the total scale, daily-activity sub-table and comprehensive-evaluation sub-table were 0.861, 0.853 and 0.748 respectively. There was a high level of consistency between two investigators. The cumulative contribution rate was 66.64% by using the principal component analysis and the maximum variance orthogonal rotation method. The preoperative score of the Catquest-8SF-CN had a significant negative correlation with preoperative binocular mean weighted visual acuity and age (P<0.05), while a significant positive correlation with education level (F=6.094, P<0.001). The patients without systemic comorbidities got higher score than those who with (P<0.05). Three months after surgery, 102 (85%) patients came for follow-up and completed the questionnaire. Significant improvement of visual acuity was observed in both binocular and monocular surgery groups (t=10.404, P<0.001). There was higher improvement in binocular weighted visual acuity of binocular surgery group than in monocular surgery group (t=-20.77, P<0.001). The postoperative score was significantly higher in both groups than before (P<0.001). There was a significant improvement in the total score after cataract surgery. The 94 patients (92.2%) were very satisfied or satisfied with the operation; 92 patients (90.2%) thought the surgery achieved their expectations, and they all felt satisfactory. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery. CONCLUSION: The Chinese version of Catquest-8SF questionnaire is suitable for the age-related cataract population in northern China. It is highly responsive to cataract surgery and brief, so it may have the potential to become part of a routine clinical assessment for cataract surgery in China. The patient’s overall satisfaction is high, which illustrates that the medical service we provide matches the patient’s needs. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery.

Cataract surgery is no more a blind rehabilitation surgery, it absolutely gives normal vision. In the era of modern cataract surgery patients expectations are also high about visual outcome. This prospective study was carried out to investigate the magnitude and pattern of pre-existing corneal astigmatism in age related cataract patient at Faridpur Medical College Hospital, Faridpur and Agha Yusuf Adhunik Hospital, Kustia, from July 2009 to June 2012. We examined 850 eyes of 730 patients who underwent cataract surgery. The mean age at the time of surgery was 61.9±8.1 (40 to 70) years. Corneal astigmatism was measured by Auto Refracto Keratometer at least two times for each patient. Astigmatism was calculated from diopteric difference of vertical reading from horizontal reading. With the rule (WTR) astigmatism was considered when steep meridian at 90°± 20°. Against the rule (ATR) astigmatism was considered when steep meridian at 180°±20°. Astigmatism is in other direction is defined as oblique. On keratometry, when vertical reading (k1) was found greater than horizontal (k2) was considered WTR astigmatism and the reverse reading for ATR astigmatism. The percentage of corneal astigmatism was 1D or less was 69.6%, more than 1D and less than 1.5D, 27.6% and more than 1.5D and less then 2D 2.8%. Prevalence of ATR astigmatism was more than WTR astigmatism and prevalence of ATR astigmatism increases significantly with age. Approximately two third of pre-operative patient had 1D or less astigmatism and one third had more than 1D corneal astigmatism. DOI: http://dx.doi.org/10.3329/fmcj.v8i1.16887 Faridpur Med. Coll.

Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

Background: Age related cataract is the leading cause of blindness and visual impairment throughout the world. With the advent of microsurgical facilities simple cataract extraction surgery has been replaced by small incision cataract surgery (SICS) with posterior chamber intra ocular lens implant, which can be done either with clear corneal incision or scleral incision. Objective: To compare the post operative visual outcome in these two procedures of cataract surgery. Materials and method: This comparative study was carried out in the department of Ophthalmology, Delta Medical College & Hospital, Dhaka, Bangladesh, during the period of January 2010 to December 2012. Total 60 subjects indicated for age related cataract surgery irrespective of sex with the age range of 40-80 years with predefined inclusion and exclusion criteria were enrolled in the study. Subjects were randomly and equally distributed in 2 groups; Group A for SICS with clear corneal incision and group B for SICS with scleral incision. Post operative visual out come was evaluated by determining visual acuity and astigmatism in different occasions and was compared between groups. Statistical analysis was done by SPSS for windows version12. Results: The highest age incidence (43.3%) was found between 61 to 70 years of age group. Among study subjects 40 were male and 20 were female. Preoperative visual acuity and astigmatism were evenly distributed between groups. Regarding postoperative unaided visual outcome, 6/12 or better visual acuity was found in 19.98% cases in group A and 39.6% cases in group B at 1st week. At 6th week 6/6 vision was found in 36.3% in Group A and 56.1% in Group B and 46.2% in group A and 66% in group B without and with correction respectively. With refractive correction, 6/6 vision was attained in 60% subjects of group A and 86.67% of group B at 8th week. Post operative visual acuity was statistically significant in all occasions. Postoperative astigmatism of >0.50D was in 82.5% subjects of group A and 52.8% subjects of group B at 1st week. At 6th week postoperative astigmatism of less than 1D was in 79.95% subjects of Group A and 83.34% subjects of Group B. About 20% subjects in Group A and only 3.3% in Group B showed astigmatism of more than 1D and these differences on both the occasions were statistically significant. Conclusion: The post operative visual outcome was better in SICS with scleral incision (group B) than in SICS with clear corneal incision (Group-A).

Introduction: Manual small incision cataract surgery (MSICS) is a cost-effective alternative to phacoemulsification cataract surgery for developing countries. This prospective study was carried out in Combined Military Hospital (CMH), Chittagong from October 2009 to March 2011 on 75 cataract patients who were operated by MSICS technique. Objectives: Aim of this study was to assess the visual outcome and complications of MSICS in a peripheral CMH. Methods: Seventy five cataract patients were operated by MSICS technique. All surgical procedures were performed by the principal author. Major per-operative and postoperative complications were documented. Visual outcome was assessed by Snellen’s visual acuity test 06 weeks after operation. Results: Uncorrected visual acuity (UCVA) was 6/6 – 6/18 in 57 (76.0%) patients, < 6/18 – 6/60 in 15 (20%) and < 6/60 in 03 (4.0%) patients. Best corrected visual acuity (BCVA) was 6/6-6/18 in 65 (86.7%) patients, < 6/18-6/60 in 07 (9.3%) and < 6/60 in 03(4.0%) patients. Visual outcome was good in 86.7% of patients according to World Health Orgnization (WHO) criteria and was not far away from the WHO expected outcome. Posterior capsule rupture was the most significant per-operative complication which was found in 7(9.3%) cases and surgically induced astigmatism was main postoperative complication that affected visual outcome. Mean postoperative astigmatism (against-the rule) was - 1.25DC. 14 JAFMC Bangladesh. Vol 10, No 1 (June) 2014 Conclusion: MSICS is a safe and cost-effective technique of extra-capsular cataract extraction where surgical skill and experience of the surgeon plays a significant role in the result.

Abstract Background Visual impairment (VI) and determinants of poor cardiovascular health are very common in sub-Saharan Africa. However, we do not know whether these determinants are associated to VI among older adults in this region. This study aimed at investigating the association between the determinants of poor cardiovascular health and near VI among older adults living in Congo. Methods Participants were Congolese older adults aged ≥ 65 years included in EPIDEMCA-FU (Epidemiology of Dementia in Central Africa - Follow-up) population-based cohort. Near VI was defined as visual acuity &lt; 20/40 measured at 30 cm. Associations between determinants of poor cardiovascular health collected at baseline and near visual acuity measured at 1 st follow-up were investigated using multivariable logistic regression models. Results Among the 549 participants included, 378 (68.8% [95% Confidence Interval: 64.9%-72.7%]) had near VI. Of the determinants of poor cardiovascular health explored, we found that having high BMI ≥ 25 kg/m 2 (Odds Ratio= 2.15 [95% CI: 1.25–3.68]), diabetes (OR=2.12 [95% CI: 1.06–4.25]) and hypertension (OR=1.65 [95% CI: 1.02–2.64]) were independently associated with near VI. Conclusions Several determinants of poor cardiovascular health were associated to near VI in this population. This study suggests that promoting a good cardiovascular health could represent a target for VI prevention among older adults.
