Cataract Technology

Eye Doctors Hawaii offers the latest technologies in cataract surgery. All surgeries are done as outpatient procedures without the need for stitches, or hospitalization. Thanks to advancements in surgical techniques and bio-engineering of lens implants, patients can choose to go completely glasses free for both distance and near vision tasks.

Cataract is a naturally occurring condition that affects the lens of your eye. Cataracts are graded along a spectrum, similar to grading increasing shades of grey. A cataract can begin by the time you are 40 years old, but do not become visually significant until much later. Cataracts are not preventable, but can be slowed down by UV protection and a healthy diet.

The lens of your eye is similar to the lens of a camera. If the lens is clear, then the image clear. If the lens is fractured or smudged, then the image is affected. At birth, your lens is crystal clear. With time, the lens becomes increasingly cloudy and fractured. This is similar to the aging of your teeth, as they turn from pearly white to dark. As a result, the image passing through lens becomes distorted and your vision becomes affected. Common symptoms include blurry vision, hazy vision, loss of color and contrast, night vision problems, and glare with lights. As a cataract achieves maturity, you might be changing or cleaning your glasses more often, or rubbing or blinking your eyes to see better.

Another property of your natural lens is its flexibility. This flexibility allows you to focus on distance and near objects without visual aides. Around your early to mid 40’s, you lose the ability to “autofocus” and you need to start using bifocals or “cheaters.” This condition is called presbyopia or age-related focus dysfunction. Presbyopia typically occurs before the onset of visually significant cataracts..

Cataract surgery basically involves two parts:

• Removal of the cloudy and inflexible cataract
• Replacement of removed lens with a new clear lens.

You have options on both how the lens is removed and what type of lens is inserted. The options you choose can affect the safety margin, the time for recovery, and your dependence on glasses for both distance and near vision.

Lens removal options with Femtosecond Laser

The science and art of surgery is constantly evolving, and we offer the latest in lens removal technologies. Removal of the aged lens can be done manually or with laser. Laser aides the surgeon during the most intricate and delicate steps of cataract removal. Using Laser actually requires more surgical time, but increases both precision and safety. The results are a higher likelihood of faster recovery and being glasses free.

Lens replacement options with monofocal versus Mulit-Focus Vision Correction

When it comes to selecting your replacement lens, the main factors to consider are: your visual objectives, your current refractive error including presence of astigmatism, your other eye conditions, your best visual potential, and your understanding of tradeoffs. Your surgeon will go over all of this with you.

Your lens choice mostly affects the number of zones in which you can be glasses free. Your zones of vision are categorized as near, intermediate, and distance. Tasks within the near zone include reading books, and any close up activities. Tasks within the intermediate zone include computer work and activities within arms length. Tasks within the distance zone includes watching TV, driving, and anything beyond 3 feet.

Once your cataract is removed, we offer 3 lens choices.

• A monofocal lens allows for vision in one zone. You will need glasses for other zones of vision. If you have astigmatism, then you might need glasses for all zones of vision. This lens is provided by your insurance.
• A toric monofocal lens. If you have astigmatism, this lens allows you to be glasses free in one zone. You will need glasses for other zones of vision.
• A Multifocus lens allows for vision in multiple zones. Most patients achieve functional reading, perform computer work, and can see in the distance without glasses.

Monofocal Lens Replacement

• Provides good vision at one distance (typically far)
• Requires reading glasses after surgery
• Covered by insurance

Toric Lens Replacement

• Provides correction of astigmatism, in either monofocal or multifocal options
• Monofocal requires glasses after surgery, whereas multifocus does not
• Not covered by insurance

Multifocus Lens Replacement

• Corrects vision for near, far, and intermediate distances
• Eliminates or reduces the need for glasses altogether
• Not covered by insurance
