What happens if the wrong lens was implanted after cataract surgery?

Likely lens exchange: Choosing the correct refractive power in the lens implanted in the eye during cataract surgery is vitally important to restoring clear vision. If the incorrect lens is mistakenly implanted, typically a second surgery to replace the lens is required. On occasion the incorrect lens is similar enough to the correct lens that minor glasses or even laser surgery can be done to correct the error.

Wrong lens: Cataract: "Intraocular (IOL) surprises" (ie, wrong lens placed) are becoming more rare with new technology such as the ORA: intraoperative aberrometry. If pt is not happy with IOL power or lens type (ie mutifocal IOL causing too much glare & halos), most IOLs can be replaced with a usually short surgical procedure. If the capsular bag is open (ie from a YAG or PC tear), there are more risk for IOL exchange.
