摘 要：Purpose: To determine the tilt and decentration of implanted intraocular lens (IOL) in vivo one year *** : A retrospective study was performed on 67 eyes by the method introduced by Guy-ton using the third and fourth Purkinje imagesm through undilated pupil. Results : The average decentration of implanted IOL was 0.68 mm, and the average tilt was 6.03°. The result was similar to the histopadiological study in postmortem eyes and the measurement in ***-regression analysis showed there was no relationship between the tilt and decentration and the residual astigmatism ,axial length ,IOL power,etc. Conclusion: The result is similar to the other methods. The method using the third and fourth Purkinje images is simple and easy to perform. It can be used for determining the IOL position through undilated pupil and does not require special apparatus.
