Accomodating interocular lens

Therefore, presbyopic surgery is one of the most difficult targets that a refractive surgeon will have to deal with today and in the immediate years.Almost all surgical techniques that have been proposed to date for the surgical correction of presbyopia are based on the acquirement of pseudoaccommodation [].

For near visual acuity, the measurement is done at 14", while for distant visual acuity, the measurement is done at 20'.

Intermediate and distance vision were improved, but not enough to do away with glasses.

An accommodating intraocular lens (IOL) allows a patient to see at different distances without needing to worry about using glasses or readers.

As we age, this the lens begins to lose some of its flexibility, making it harder to change focus quickly.

Disclaimer: Each patient has unique visual characteristics and requires the consultation of a qualified eye surgeon before determining what treatment modality is best.

The aging population, especially in western countries, has created millions of candidates around the world for such interventions.

Current non-surgical treatment options include reading spectacles (either mono or varifocal) and contact lenses (either multifocal or monofocal for monovision), but many of these patients, spectacle independent previously, do not easily accept this unavoidable age-related life style change.

The procedure costs about $4,500 per eye, compared to $1,600 for ordinary cataract surgery.

This is the only FDA approved accomodating lens, but there are other technologies available.
