The tilt and decentration of intraocular lens (IOL) result in defocussing, astigmatism, and wavefront aberration after operation.
The objective is to give a method to estimate the tilt and decentration of IOL more accurately.
Based on AS-OCT images of twelve eyes from eight cases with subluxation lens after operation, we fitted spherical equation to the data obtained from the images of the anterior and posterior surfaces of the IOL.
By the established relationship between IOL tilt (decentration) and the scanned angle, at which a piece of AS-OCT image was taken by the instrument, the IOL tilt and decentration were calculated.
IOL tilt angle and decentration of each subject were given.
Moreover, the horizontal and vertical tilt was also obtained.
Accordingly, the possible errors of IOL tilt and decentration existed in the method employed by AS-OCT instrument.
Based on 6–12 pieces of AS-OCT images at different directions, the tilt angle and decentration values were shown, respectively.
The method of the surface fitting to the IOL surface can accurately analyze the IOL’s location, and six pieces of AS-OCT images at three pairs symmetrical directions are enough to get tilt angle and decentration value of IOL more precisely.
