Visual acuity and complications following cataract extraction with intraocular lens implantation

Modern cataract surgery yields excellent visual acuity and is very safe.

A Cochrane review (abstract , review ) included 6 studies with a total of 7828 subjects. Phacoemulsification gave a better visual outcome than extracapsular surgery and gave a similar average cost per procedure in one trial conducted in the UK. Extracapsular surgery with posterior chamber lens implant and intracapsular surgery with or without an anterior chamber intraocular lens implant gave acceptable visual outcomes at 12 to 24 months after surgery.

A systematic review including 90 studies was abstracted in DARE. A high rate (> 95%) had visual acuity of greater than 20/40 following surgery. There is a low rate of complications with the exception of posterior capsule opacification that had an overall rate of 19.7%. Since this complication is easily treated it was not considered a major issue.
