Can you please tell me about an intraocular lens?

Vision correction

Intraocular_lens
A cataract is a loss of transparency of the natural lens. Removal of the cataract means the focusing element of the eye is therefore removed. To replace this, an inert plastic intraocular lens has been developed which can be permanently implanted in the eye to replace this focus. It is now a routine part of cataract surgery.

If some one gets cataract surgery then he/she will need lens implant to replace the natural lens that developed into cataract. The lens made of inert material that is not allergenic or immunogenic therefore it does not cause any reaction.

Dr. Val Zudans answered:

Tell me about intraocular lens implants (monovision)?

Monovision IOLs

Intraocular_lens
Monovision (one eye distance focus, one eye near) is a common method to correct presbyopia (loss of reading vision over age 40). The + is an increased independence from glasses. The - is a loss of depth perception and potential imbalance. A trial of monovision with contact lenses is recommended before surgical correction (cataract lens implants or laser vision correction).

Dr. Harvey Fishman answered:

What is the best intraocular lens after cataract removal?

Several

Glasses
Depends on what your final goals are. If you would like independence from glasses, consider multifocal lenses. They do carry risk of halos and reduced contrast. They work well for the appropriately chosen patient. Make sure that you have a wavefront measurement as well as topographic images as higher order aberrations or corneal irregularities like forme fruste keratoconus are contraindicated.

Can intraocular lens replacement surgery ever be reversed?

For cataract surgery

Cataract
When we perform cataract surgery we remove the lens of the eye. In order for the patient to see the lens needs to be replaced. This lens implant is permanent and should not need to be replaced in the future. The implant lens can be removed if necessary however removal of the implant lens may be difficult. It is not usually done unless the patient is having significant difficulty.
