“…In this study, about thirty-nine percent of corneal transplantation indicated patients had accepted the transplantation. is result is higher than the study finding of cataract surgery in Tanzania (17.8%) [11]. e possible justification for this discrepancy could be the difference in the study design; the current study was cross-sectional, while the study in Tanzania was cohort.…”

Background. For so long, corneal diseases have been known as one of the leading causes to blindness in the global. is blindness might be due to failure to accept the corneal transplantation.erefore, this study aimed to determine the prevalence and the root challenges for corneal transplantation acceptance at the University of Gondar tertiary eye care and training center, Ethiopia. Methods. An institution-based cross-sectional study was conducted among patients who had an indication for corneal transplantation at the University of Gondar tertiary eye care and training center since January 1, 2017, up to October 30, 2018. A structured questionnaire was used to collect the data and entered into Epi-Info 7 software and analyzed using SPSS version 20. Simple logistic regression was used to identify the associated factors of corneal transplantation acceptance. Associations between outcome and exposure variables were expressed by the adjusted odds ratio with a 95% confidence interval and p value <0.05. Result. A total of 116 patients with a mean age of 51 (±21) years participated in the study. e overall acceptance level of corneal transplantation was only 38.8% (95% CI: 29.93, 47.66). Patients with poor knowledge [AOR � 2.41; 95% CI: 1.90, 6.48] and an unfavorable attitude [AOR � 6.33; 95% CI: 2.42, 16.54] were significantly associated with the acceptance of corneal transplantation. Conclusion. e study revealed that the corneal transplantation acceptance level was very low. Hence, the government and other concerned stakeholders should give due emphasis to the awareness creation and behavior change communication strategies to increase the acceptance level of corneal transplantation.

“…Our findings indicate that by recruiting patients with cataract who are younger and/or have better pre-operative VA, a reduction in the proportion of poor outcomes may be possible. A cohort study of patients with operable cataract from Tanzania in close proximity to an eye care programme found that only 23 % of potential cataract surgical candidates had blindness or severe visual impairment, and that the elderly were the least likely group to accept free surgery [24]. This suggests that other measures in addition to visual acuity, such as vision-related quality of life, may be useful to select patients for surgery, and may reduce the likelihood of a poor outcome.…”

The aim of this study was to investigate the outcomes of sutureless, manual small-incision cataract surgery (SICS) in rural sub-Saharan Africa using standard intraocular lenses (IOLs). In order to assess the quality of surgery, we prospectively evaluated the visual outcomes of 1455 consecutive cataract operations performed in 2006 in patients ≥40 years at Nkhoma Eye Hospital, Malawi. All operations used standard 22-dioptre IOLs without pre-operative biometry. Outcomes were categorised according to the World Health Organization criteria, and causes of a poor outcome were recorded. Mean age of patients was 71.5 ± 9.5 years, and 53 % were female. Pre-operatively, 64 % of eyes had a visual acuity (VA) <6/60, and 41.3 % of eyes were blind (VA < 3/60). Without correction (uncorrected VA), nearly eighty percent (78.7 %) achieved a 'good' outcome (VA 6/6-6/18), 19.8 % were 'borderline' (VA < 6/18-6/60), and 1.5 % had a poor (VA < 6/60) outcome. With pinhole-correction, the proportion of good outcomes increased to 89.4 %, and poor outcomes decreased to 0.9 %. Poor outcomes were most commonly due to ocular co-morbidities (54.5 %) and refractive error (36.4 %). Older age and pre-operative blindness were strongly associated with borderline or poor visual outcomes. The most common surgical complication was posterior capsule tear (without vitreous loss). In a rural African environment, using standard IOL power plus SICS can lead to a high proportion of good outcomes and a low frequency of surgical complications. A comparative study is required to determine if any additional benefit in visual outcomes can be gained by the addition of biometry.

“…We believe that there are more elderly blind who do not attend and they might not be represented by the population we studied. However, other population-based data from the same area also indicate that cataract acceptance rates are low even when surgery is free and transport is provided 11. One might argue that the true test of how cost affects acceptance would be a randomised controlled trial.…”
