Clinical Observation Of Implanting Iris-fixated Intraocular Lens For High Myopia

Objective: To observe the clinical effect of implanting iris-fixated intraocular lens(IFIOL) in anterior chamber to correct high myopia.Methods: Four patients (8 eyes) with -13.50D- -31D myopia included in this study. Ocular axial length, anterior chamber depth and corneal curvature were measured for iris-fixated intraocular lens(IFIOL) selection. During the operation, the IFIOL s were implanted into anterior chamber. The uncorrected and best corrected distance visual acuity (UCDVA/BCDVA), introcular pressure (IOP), anterior chamber flare, contrast sensitivity, IFIOLs position and pupil reflex and gonioscopy were observed during 6 month follow-up periodResults: After the operation, uncorrected visual acuity of all eyes was better than or equal to preoperative corrective visual acuity, and contrast sensitivities of 8 eyes were improved than preoperative contrast sensitivities. Dazzling sensation occurred in a patient and at same time IOP increased on right eye in one week without other complicatiom.Conclusion: Implanting IFIOLs to correct high Myopia is effective, safe, stable,yet it needs more cases and longer follow-up to make the further conclusion.
