Z syndromes are rare, but do need to be ruled out for any Crystalens patient who has a refractive shift.

This is especially advantageous when any ocular pathology that affects vision is present, such as significant ocular surface disease, corneal dystrophies such as EBMD, macular pathologies or glaucoma.

And these lenses provide at least some accommodation, unlike standard IOLs.

Any amount of capsular contraction can limit the movement of the lens and push it slightly anteriorly.

This can result in limited accommodation and a slight myopic refractive shift.

Due to anatomical differences, patients will experience varying amounts of accommodation: some may experience over two diopters of accommodation, but most will experience around 1.00D to 1.50D.

In rare cases, a patient will experience little to none.The accommodative effects of the lens are often not realized for several weeks to months after implantation, and patients should be counseled accordingly.The targeted refraction should be realized immediately, and postoperative management for the first several weeks is no different than a standard IOL.forecasts nearly 11% growth in presbyopia-correcting IOLs through the end of 2016 as new options become available. Presbyopia correction can be approached in a number of ways.Multifocal IOLs incorporate discrete optical elements into the lens to offer both near and distance vision.Dilation can be considered as soon as several weeks post-op, but is usually not necessary for at least a month.
