To investigate intraocular lens (IOL) movement, measured by two kinds of instruments in different states.
The IOL movement was measured using anterior segment optical coherence tomography (AS-OCT) and optical low-coherence reflectometry in 38 pseudophakic eyes. Postoperative uncorrected visual acuity was greater than or equal to 0.8 and none complication occurred in all patients. A: Change of IOL position in fogging and accommodating states, measured by AS-OCT. B: Change of IOL position before and after torchlight irradiating on the unexamined eye, measured by AS-OCT and optical low-coherence reflectometry. C: Change of IOL position before and after using 1% pilocarpine, measured by AS-OCT and optical low-coherence reflectometry.
22 eyes were acrylic monofocal intraocular lenses, including 4-haptic IOL and L-haptic IOL. 16 eyes were L-haptic acrylic multifocal intraocular lenses. There was no change of IOL position in A and B. IOL movement were 92.4±12.1um measured by AS-OCT and 92.3±12.1um measured by optical low-coherence reflectometry in C. The IOLs showed backward movement except 4 IOLs in which there were no change.
Our results suggest that IOL do not move in accommodation state and pupil constriction state caused by torchlight, while mainly move backward when using 1% pilocarpine.
