What are the problems with toric IOLs?

Toric IOLs, the medical devices for astigmatism correcting intraocular lenses, are usually used at the time of cataract surgery to reduce post-operative astigmatism.

Problem with IOLs:

  • Rupture of lens capsule: at the time of the procedure if the capsule is accidentally ruptured and the intraocular lens cannot be implanted in the posterior chamber, the anterior chamber intraocular lens should be implanted, or the operation should be performed again.
  • Dislocation of the lens: it is caused by the fragile and easily damaged ciliary ligament.
  • Intraocular infection: it is a serious complication. It causes blindness once it happens.
  • After the IOL implantation, a clouding of the lens capsule, known as a “secondary cataract” occurs in roughly 40 percent of cases.
  • Other potential complications: astigmatism may be over-corrected or under-corrected.

In any case though, if you or someone close to you feels as if they have an underlying issue going on, please go see a doctor for professional help.
