Comparison of visual acuity between phacoemulsification and extracapsular cataract extraction: a systematic review and meta-analysis.

Background: Surgical treatment is the primary intervention for cataracts. Extracapsular cataract extraction (ECCE) is a routine surgery for cataracts, phacoemulsification (PE) is another procedure with a small incision and injury area. This study investigated the comparison of the effects of these two procedures on the patient's visual acuity.
