OBJECTIVE: To investigate the relationship between high frequency component of accommodative microfluctuation (HFC) and the pseudo accommodation after the implantation of foldable intraocular lenses (IOL).
METHODS: With ARK-730A accommodation analyzer we checked HFC in 50 cases (50 eyes) of patients who had good pupil reaction to light and the pupil diameter was 2.0 approximately 3.5 mm approximately. Three months after the implantation of foldable IOL, the relationship among ciliary muscle accommodative microfluctuation, IOL movement and pseudo accommodation was analyzed.
RESULTS: There was positive correlation between ciliary muscle accommodative microfluctuation and IOL movement (r = 0.702, P < 0.01), between IOL movement and pseudo accommodation (r = 0.861, P < 0.01), and between ciliary muscle accommodative microfluctuation and pseudo accommodation (r = 0.915, P < 0.01). Pseudo accommodation was greater in patients who showed more ciliary muscle accommodative microfluctuation and IOL movement.
CONCLUSION: HFC induces IOL movement, and it is one of the most important reasons for pseudo accommodation after foldable IOL implantation.
