Eyesight is the only of the five senses which has the biggest effect on us humans. We have come to rely on eyesight above hearing or touch much more. This could be one reason why, if we lost our eyesight we would feel lost in ourselves.

Eyes are precious, and for that reason funding for research into eyesight problems is always going to be very high indeed.

One of the most recent discoveries in the area of eye surgery is light adjustable lenses. Before the light adjustable lense, there was the intraocular lens, which was invented around the 1950’s.

The United States often makes significant advances in technology, and it is for that reason that light adjustable lenses were a discovery by Calhoun Vision. The technology targets people with cataracts or short sighted people and the end result offers 20/20 vision.

The way it works is the vision is either bifocal or varifocal, meaning those who have undergone the eye surgery will be able to see words in book or details from a distance. This means those people no longer have to use glasses as well.

The LAL or light adjustable lense procedure is relatively straightforward; the LAL is put into place and then using ultraviolet light shone on it makes the lense adjust according to the eye surgeons’ needs for their patient.

There is an alternative which is the presbyopia-correcting intraocular lense, but it has the downfall of most patients still needing reading glasses even after surgery has taken place.

Interestingly enough, cataract surgery can be helped as well, that is, on eyes that have already had cataract surgery – light adjustable lenses can aid in that they can correct any faults made when the previous lenses were put in place.

This new Light Adjustable Lense (LAL) technology it can change people’s eyesight to even better than it was from a young age. One good thing is that even two weeks after surgery, adjustments can still be made.

Critics have stated that they would need more long term evidence of the LAL working on patients. They also said there could be additional costs involved with LAL if patients need to go back to the hospital again.
