臨床指數包括了四項臨床變數：年齡、術前視力、活動力、身體狀況。我們以臨床指數來預估白內障術後視力，誤差不超過視力表一行者：A組59%，B組59%，PAM組40%；誤差不超過視力表二行者：A組75%，B組78%，PAM組61%。可見以臨床指數來預估白內障術後視力準確性比以PAM預估者高，不失為一種方便又有效的方法。

A clinical index was used to predict the postoperative visual acuity of cataract patients aged 50 and older. The index consisted of four statistically combined factors: age, pre-operative visual acuity, frequency of television watching, com-morbidity, (drug numbers and diseases duration). Validation of the index included comparision to the potential acuity meter. For the index, 59% and 75% of prediction were accurate within one and two snellen lines of post-operative visual acuity respectively compared 40% and 61% using the potential acuity meter. Testing the external validity of the clinical index, using data from different ophthamologist disclosed 59% and 78% of predicting accurate within one and two snellen lines. Clinical index is a useful method to predict visual acuity after cataract surgery.
