There have been many reports describing the use of formulas to derive lens implant power in cataract surgery. Typically over 80 per cent of patients are said to have a final refraction within one dioptre of the desired value. In our clinical practice results are worse. Modification of the formula to suit an individual surgeon and implant style would probably improve results.
已有许多报告描述了在白内障手术中使用公式来推导人工晶状体植入度数的情况。通常据说超过80%的患者最终屈光度数在预期值的1屈光度范围内。在我们的临床实践中，结果更差。调整公式以适应个别外科医生和植入方式可能会改善结果。
