These surgical complications include, but are not limited to infection, increased IOP, corneal edema, posterior capsular opacification (PCO), IOL decentration, and retinal detachment.The other major side effect experienced by patients after IOL implantation are visual disturbances.Intraocular lens implants (IOLs) are used in both refractive lens exchange and cataract surgery to replace the natural lens of the eyes and correct for refractive errors.Over recent years, many improvements in intraocular lenses have allowed for the development of a wide-spectrum of lenses beyond the traditional monofocal lens implants.Well, what if there was a way to have cataract surgery and restore vision at all distances? As the name implies, a multifocal IOL offers more than one lens power.The technology functions very much the same as progressive eyeglasses and multifocal contact lenses.Additionally, while patients may have better levels of contrast sensitivity and less ocular aberrations, they may experience a unique visual phenomenon typically described as "starbursts." In a prospective randomized study comparing Crystalens, Re STOR, and Tecnis IOLs, the Re STOR demonstrated better UNVA compared with Crystalens and Tecnis, with the Crystalens accommodating IOL demonstrating better intermediate and low-contrast distance-corrected vision compared to Re STOR and Tecnis.

There are several different types of multifocal IOLs approved by the FDA for use in the U. The lenses below are the most commonly used multifocal IOLs in the U.Despite the high level of patient satisfaction with IOLs, studies have demonstrated that patients are no more satisfied with IOLs than with other correction strategies.In a meta-analysis of 20 clinical trials comparing multifocal and monofocal lenses, patients with multifocal IOLs were 3.6 times less likely to require spectacles compared to patients with monofocal IOLs.Trifocal IOLs are popular presbyopia-correcting IOLs in many areas outside of the United States.Compared to the bifocal diffractive IOL, the trifocal IOL improves intermediate vision by providing a third focus.
