Q Will cataract surgery also treat presbyopia?
A Monofocal intraocular lens (IOLs) and multifocal IOLs are available for implantation following the removal of a cataract. Monofocal IOLs provide only a single focus point. Therefore, if the implanted lens is set to focus on distant objects, near vision will be blurry, thus requiring the aid of reading eyeglasses. Although multifocal IOLs allow patients to see both far and near well enough without eyeglasses in most daily routines, performing intricate detailed work would still require eyeglasses.

Q Is the multifocal IOL suitable for anyone having cataract surgery?
A A pupil size that is too small under bright conditions will interfere with the lens’ ability to offer both near and far vision. However, monofocal IOLs are suitable for patients with the same pupil size.

Q Will patients who have received a LASIK or phakic IOL procedure be able to undergo cataract surgery?
A Yes, however, the phakic IOL would have to be removed prior to cataract surgery.

Q Can a monofocal IOL implanted in a previous cataract surgery be replaced with a multifocal IOL?
A Whether it can be replaced depends on the conditions of the IOL and the capsule, which can be examined after pupil dilation. Such a replacement procedure is possible within a few months following cataract surgery.
