A cataract is a “clouding” of the lens in the eye, which normally is clear and transparent. The most common type of cataract is related to natural aging process of the eye, but other causes can be, hereditary, lesion of the eye, medical problems such as diabetes, drugs such as steroids, or long exposure to sun rays without proper eye protection. Cataracts are common cause for poor vision, mainly in elderly people.


There are no medications, nutritional supplement, or exercises that have proven to cure or avoid Cataracts. Surgery is the only method to eliminate a cataract. Cataract surgery is a simple operation performed under local anesthesia without the need for hospitalization. Through a tiny incision, the clouded lens is removed, and a new permanent artificial IntraOcular Lens is implanted.

Intraocular Lens

What is an Intraocular Lens (IOL)?
An intraocular lens (IOL) is an artificial lens that’s implanted during cataract surgery.  The good news is that you’ve encountered cataracts at a time when intraocular lens technology has taken great leaps of progress.

Due to recent advances the new generation lenses allow most patients to see well at all distances without the help of glasses, bifocals, or reading glasses. The following are three primary types of lenses currently available for you to choose from with the advice from Dr. Montoya.

AcrySof – ReSTOR IOL are designed to replace cataracts and correct presbyopia at the same time. The goal is to give you a full range of clear vision, near to far, and everywhere in between. 

AcySof-Toric IOL are for patients with existing corneal astigmatism. Similar to monofocal lenses, these lenses usually give patients quality distance vision with less dependence on glasses. Most patients will still need to wear glasses for tasks such as reading or working at a computer.

Crystalens are for implantation in the capsular bag of the eye for the visual correction of aphakia secondary to the removal of a cataractous lens in adult patients with and without presbyopia. The lens rests back in the eye to accommodate distance vision, then gently flexes forward to accommodate intermediate vision, and then further forward for near vision. The superior movement is enabled by a flexible hinge within the lens.
