Six hundred and seventy-six patients had both their cataracts removed in one operating session because of the rural and economic conditions of Malawi. These operations were performed over a period of 5 years. The final visual results were satisfactory and the number of complications acceptable in relation to the environmental conditions and medical facilities available. However, the incidence of infection is higher than would be acceptable in a sophisticated medical environment. Three eyes were lost owing to infection, but fortunately in all 3 cases the fellow eye was not affected. Furthermore, broken capsule and vitreous loss occurred more frequently than expected in a sophisticated facility in the eye first operated on. This allowed measures to be taken by the surgeon in many cases to prevent these complications from recurring in the second eye.
由于马拉维的农村和经济状况，676名患者在一次手术中摘除了双侧白内障。这些手术历时5年完成。最终的视力结果令人满意，并发症的数量与现有的环境条件和医疗设施相比是可以接受的。然而，感染发生率高于在先进医疗环境中可接受的水平。有3只眼睛因感染失明，但幸运的是，在所有这3例中，对侧眼未受影响。此外，与先进设施中首次手术的眼睛相比，晶状体囊破裂和玻璃体丢失的发生频率更高。这使得外科医生在许多情况下能够采取措施，防止这些并发症在第二只眼睛中再次出现。
