Brief summary

This study evaluates the safety and efficacy simultaneous, trans-conjunctival, 25-Gauge vitrectomy and phacoemulsification with intraocular lens implant in patients with metamorphopsia and visual impairment due to idiopathic epiretinal membrane and cataract. All 30 patients recruited underwent complete ocular examination, visual acuity measurement with ETDRS, metamorphopsia assessment with M-Charts and Metamorphometry® and foveal thickness evaluation by sd-OCT preoperatively, at 30, 90, 180 days postoperatively.

Interventions

PROCEDUREPhacoemulsification, intraocular lens implant, vitrectomy.

Cataract extraction, intraocular lens implant, vitrectomy, epiretinal membrane and inner limiting retinal membrane peeling.
