If you have cataracts, you are considering surgery because your cataracts prevent you from seeing well even with corrective eyeglasses. After cataract surgery, you should be able to see well at far, mid-range, and near distances with new eyeglasses(assuming no other eye health problems). The decision about which type of artificial lens implant to have will affect your ability to see without eyeglasses following cataract surgery. There are 3 categories of artificial lenses for cataract patients to choose from: single focus (monofocal), bifocal (also called a multifocal because it has 2 separate focal points), and extended focus.

Your outpatient surgery will be performed at the Peninsula Eye Surgery Center in Mountain View, CA, This was the first surgery center from San Francisco to San Jose to specialize in eye surgery only, and performs one of the highest volumes of cataract surgery in Northern California. The eye is numbed by anesthetic drops, rather than the conventional shot of Novocaine. Thanks to light sedation, you will feel calm and relaxed, but awake.

An eye bandage is not necessary when topical anesthesia is used. With small incision surgery, you may resume everyday activities and physical exercise as soon as you like. As with any surgery, the healing period will vary with each individual. Use of the eye is not harmful, but the vision is normally blurry at first. Your eyeglass prescription will be differen tafter surgery and will be changed approximately one month later.

Eye drops being applied
To take the place of the clouded human lens, a tiny, delicately engineered artificial lens is implanted into the eye. Recently, newer implant designs that can decrease your dependence upon glasses have become very popular. However, they are not appropriate for all individuals, and the additional cost is not covered by insurance.
