What are the disadvantages of cataract surgery?

Is it better to be nearsighted or farsighted after cataract surgery?

Can an intraocular lens be damaged?

As a consequence of this increased manipulation, intraocular lenses (IOLs) are more prone to damage. This is particularly true for hydrophilic acrylic lenses, in which up to 28% have been reported to be damaged after injection. The cause of IOL damage is varied.
