Input: Three trials randomly allocating people with age-related cataract to MSICS or ECCE were included in this review (n = 953 participants). Two trials were conducted in India and one in Nepal. Trial methods, such as random allocation and allocation concealment, were not clearly described; in only one trial was an effort made to mask outcome assessors. The three studies reported follow-up six to eight weeks after surgery. In two studies, more participants in the MSICS groups achieved unaided visual acuity of 6/12 or 6/18 or better compared to the ECCE group, but overall not more than 50% of people achieved good functional vision in the two studies. 10/806 (1.2%) of people enrolled in two trials had a poor outcome after surgery (best-corrected vision less than 6/60) with no evidence of difference in risk between the two techniques (risk ratio (RR) 1.58, 95% confidence interval (CI) 0.45 to 5.55). Surgically induced astigmatism was more common with the ECCE procedure than MSICS in the two trials that reported this outcome. In one study there were more intra- and postoperative complications in the MSICS group. One study reported that the costs of the two procedures were similar. There are no other studies from other countries other than India and Nepal and there are insufficient data on cost-effectiveness of each procedure. Better evidence is needed before any change may be implemented. Future studies need to have longer-term follow-up and be conducted to minimize biases revealed in this review with a larger sample size to allow examination of adverse events.
Output:

We found three randomised controlled trials. The searches are up to date to September 23rd 2014. A total of 953 people with age-related cataract in India and Nepal were randomly allocated to MSICS and ECCE in these trials. The data were limited. People whose lens was removed with MSICS were more likely to achieve good functional vision, however, overall not more than 50% of people achieved good functional vision in the two studies. 1.2% of people enrolled in two trials had a poor outcome after surgery with best-corrected vision less than 6/60. There was no evidence of any difference between the two groups with respect to this outcome. Surgically induced astigmatism was more common with the ECCE procedure than MSICS in the two trials that reported this outcome. In one study there were more intra- and postoperative complications in the MSICS group. One study reported that the costs of the two procedures were similar. We judged the quality of the evidence to be low or very low. There were only three studies and we could not combine the data because of differences in reporting and inconsistency between trials which meant that some of the results were imprecise.
