Effect of Multifocal Intraocular Lens on Contrast Sensitivity in Primary Angle-Closure Patients

Thailand35 participantsStarted 2014-01-02

Plain-language summary

This prospective study included patients with primary angle-closure (PAC or primary angle-closure glaucoma (PACG) and visually significant cataract. Phacoemulsification with multifocal intraocular lens (MIOL) or monofocal IOL (mIOL) (patient preference) was performed. Collected data included best-corrected distant visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), and contrast sensitivity (CS) measured at spatial frequency 1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree (CPD) preoperatively, and at 2-6 months postoperatively. Preoperative and postoperative parameters were compared to evaluate the effect of MIOL on CS in eyes with PAC or PACG.
