Abstract

|
|
Purpose: To compare clinical outcomes between iris fixation and scleral fixation as treatments for dislocated Intra Ocular Lens.
Methods: Ten eyes of 10 patients underwent scleral fixation (scleral fixation group) and 8 eyes of 8 patients underwent iris fixation (iris fixation group) were enrolled in this retrospective study. In each group, visual acuity and intra ocular pressure, slit lamp examination, fundus examination, refraction, keratometry, axial length and anterior chamber depth were measured before the surgery. Regular follow up was made 1 day, 1 week, 1 month, and 2 months after surgery and visual acuity, intra ocular pressure, slit lamp exam, refractory error, anterior chamber depth, intraocular lens (IOL) tilting, and decentration were measured at each visit.
Results: There were no significant differences in uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and refractive error for patients with iris and scleral fixation before and after surgery. Patients with iris fixation had significantly deeper anterior chamber depth (ACD) and more IOL tilting than patients with scleral fixation.
Conclusions: In this study, the iris fixation group tended to have more IOL tilting and deepening of anterior chamber depth than the scleral fixation group. We can use this information to choose the appropriate surgical method for dislocated IOL and to select of new IOL.
