A birth of interest in lens implantation occurred especially in the United states in 1974. This coincides with the beginning of four major American lens manufacturers. This interest expoded in 1975 and 1976 and seems to be continuing to grow. Only a few surgeons have stopped implants, most of them after having done ten or less. Half of the surgeons now doing implants have done 25 or less, while 40% have performed a series of 25 to 200. Intracapsular lens styles were the most often used, and the Worst Medallion lens was by far the most popular. Medical Workshop was the leading supplier of lens implants. Accounting for 25%, and European lenses were more often used (61%). The majority of surgeons beginning lens implants after 1974 used either American lenses exclusively or both sources. The majority of lenses used were designed by Binkhorst and Worst. Only 4% of lenses implanted were done secondarily, but one third of the surgeons have performed this procedure; more do them as their experience grows. An overall visual acuity of 20/40 or better postoperatively was found in 83.8% of cases. Significant lens power errors were rare but increased with increasing experience. One third of the surgeons have reported removing a lens implant at a rate of 0.8%, but only 3% of the surgeons have reported removing an eye with a lens implant at a rate of 0.05%.
1974年，尤其是在美国，人们对晶状体植入产生了浓厚兴趣。这与美国四大主要晶状体制造商的创立时间相吻合。这种兴趣在1975年和1976年迅速增长，并且似乎还在持续上升。只有少数外科医生停止了植入手术，其中大多数是在做了10例或更少之后。现在进行植入手术的外科医生中，一半做了25例或更少，而40%完成了25至200例的系列手术。囊内晶状体类型使用最为频繁，其中最差奖章晶状体是迄今为止最受欢迎的。医学工坊是晶状体植入物的主要供应商，占25%，欧洲的晶状体使用更为频繁（61%）。1974年之后开始进行晶状体植入手术的大多数外科医生要么只使用美国的晶状体，要么同时使用这两种来源的晶状体。使用的大多数晶状体是由宾克霍斯特和沃斯特设计的。只有4%的植入晶状体是二次植入，但三分之一的外科医生进行过这种手术；随着经验的增加，更多医生会做这种手术。术后总体视力达到20/40或更好的病例占83.8%。明显的晶状体屈光度误差很少见，但随着经验的增加而增多。三分之一的外科医生报告以0.8%的比率取出过晶状体植入物，但只有3%的外科医生报告以0.05%的比率摘除过带有晶状体植入物的眼睛。
