Multifocal vision after cataract surgery.

Recent improvements in cataract surgery and intraocular lens (IOL) technology have allowed rapid improvement in quality visual acuity. Cataract surgeons can also reliably reduce a patient's dependency on spectacles. Through careful monitoring of implant power calculations to improve their accuracy and reduce unwanted astigmatism, our patients are now able to enjoy clear, uncorrected vision. Newer technology, such as multifocal IOLs and accommodating IOLs, can provide a return to prepresbyopic visual acuity for the cataract patient.
