Abstract Details


One of the greatest issues facing the cataract surgeon today is accurate prediction of post-operative refractive error. With use of intraoperative autorefractometry (IOAR), large errors can be detected, and we were able to avoid the unpleasant surprise of a mistaken intraocular lens power. But there is possibility of inaccurate measurement. Therefore we examined whether corneal refraction could be predict reliability of refractive measurement with IOAR.


Department of Ophthalmology, Showa University, School of Medicine, Yokohamashihokubu Hospital.


Ninenteen nine eyes of peformed cataract surgery with IOAR during August 1,2012 to January 31,2013 and corrected acuity 0.7 divided to two groups.The difference between preoperative corneal refraction and intraoperative corneal refraction was ḟ0.5Diopter (Group A) or over 0.5D(Group B) We difined success is the difference between predictive refraction and post operative refraction was ḟ??.


Success rate was 87.9% (87 eyes of 99 eyes) in all cases. In group A, it was 93.4%(61 eyes of 57 eyes). In group B, it was 78.9% (30 eyes of 38 eyes). Significant difference was observed between group A and groupB(p<0.05)


Corneal refraction could be predict reliability of refractive measurement with IOAR.
