The preoperative testing of retinal acuity was evaluated using two instruments in each of 35 eyes having extracapsular cataract extraction. Retinal acuity was measured using the SITE IRAS hand-held interferometer and the Haag-Streit Lotmar visometer. The postoperative findings are given for comparisons of final acuity, prediction, and instrument evaluation. The results showed predicted acuity to be within two lines of the final acuity in 57.1% of eyes with the Haag-Streit unit and in 42.8% of eyes with the SITE instrument. The instrument differences were more in procedure than in results.
在35只接受白内障囊外摘除术的眼睛中，每只眼睛使用两种仪器对术前视网膜视力进行评估。使用SITE IRAS手持式干涉仪和Haag-Streit Lotmar视力计测量视网膜视力。给出术后结果以比较最终视力、预测情况和仪器评估。结果显示，使用Haag-Streit仪器的眼睛中，57.1%的预测视力与最终视力相差两行以内；使用SITE仪器的眼睛中，42.8%的预测视力与最终视力相差两行以内。仪器在操作上的差异比结果上的差异更大。
