Numerous studies have shown that pseudophakic surgery is a better (because it is a more natural) method of restoring binocularity than contact lenses or aphakic spectacles provided that the potential for binocular vision was present before the onset of the cataract(s). However, this restoration is achieved more easily in some groups of patients than others. Unilateral: Excellent prognosis for binocularity is retained for many years--even 50-60 years--in adult unilateral traumatic cataract/aphakia. At the other extreme are patients born with one normal eye and the other containing a well-marked cataract. In unilateral traumatic cataract/aphakia in children the potential for restoration of binocularity is related to age--the older the child, the better the chances. To achieve binocularity central vision must not fall below 20/70 in each eye. Bilateral: There is not much to choose between pseudophakia and contact lenses; both are effective in restoring binocularity, and both are superior in this respect to cataract spectacles of keratophakia.
大量研究表明，对于双眼视觉潜能在白内障发病前就已存在的患者，人工晶状体植入手术是恢复双眼视功能的一种更好（因为它更接近自然状态）的方法，比佩戴隐形眼镜或无晶状体眼镜效果更好。然而，在某些患者群体中，这种恢复比其他患者群体更容易实现。单眼情况：对于成年单眼外伤性白内障/无晶状体眼患者，多年来（甚至50 - 60年）保留双眼视功能的预后良好。另一个极端情况是，一只眼睛正常而另一只眼睛有明显白内障的先天性患者。在儿童单眼外伤性白内障/无晶状体眼中，恢复双眼视功能的可能性与年龄有关——孩子年龄越大，恢复的机会越好。为了实现双眼视功能，每只眼睛的中心视力不得低于20/70。双眼情况：人工晶状体植入和佩戴隐形眼镜之间没有太大差别；两者在恢复双眼视功能方面都有效，且在这方面都优于白内障眼镜或角膜屈光手术。
