What Is Cataracts?


Nearly everyone will develop cataracts at some point. Cataract is the term used to describe a clouding of the natural lens of the eye. This clouding of the lens is part of the normal aging process. Cataracts most often start to cause a noticeable difference in vision after 60 years of age. However, the formation of a cataract can be accelerated by many other factors besides age. These factors include trauma to the eye, infection, previous eye surgery and certain medications. Rarely, an infant is born with cataracts.


Are Cataracts Only Developed In Older People?


Most cataracts develop slowly over time and affect people over age 50. About half of the U.S. population has a cataract by age 65, and nearly everyone over age 75 has at least a mild cataract in one or both eyes.


  • Clouded, blurred or dim vision
  • Increasing difficulty with vision at night, especially with oncoming headlights
  • Sensitivity to light and glare
  • Need for brighter light for reading and other activities
  • Seeing “halos” around lights
  • Frequent changes in eyeglass or contact lens prescription
  • Fading or yellowing of colors
  • Double vision in a single eye


Just imagine, with ONE surgery, we can fix astigmatism, presbyopia, refractive error, and cataracts!

We have the ability to do this and we’re one of the few places that can offer this in the state of Hawaii. ​All of our 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 glasses free for both distance and near vision tasks.

Eye Doctors Hawaii Uses The Latest Lens Technologies for Cataract Lens Replacement.


In addition to monofocal lenses, we offer: Toric, Multifocal, Toric-Extended Depth of Focus (Symfony), and Toric-Trifocal Lenses (Panoptix).  The appropriate lens selection depends on many indiviudal factors.  One lens is not appropriate for everyone.  Your surgoen, Dr. Chang, will go over the pros and cons of each choice with you


What Is the Symfony and Symfony Toric Lens? How does these lenses work?


FDA approved of The Symfony® Lens in 2016. This is the first Active Life Lens that corrects astigmatism, presbyopia, refractive errors and provides cataract patients with an extended depth-of-focus, which helps improve their sharpness of vision at intermediate, and far distances.

What Is the Vivity Intraocular Lens and is right for me?


The Vivity lens was FDA approved in September 2020.  When combined with cataract surgery, the lens can provide clear distance vision (watching TV and driving) and intermediate vision (computer work, applying makeup or shaving).  The lens has unique features that decrease the risk of glare and halos that can occur with other premium lenses.  This lens is an excellent option for people who have had prior LASIK surgery or who don’t want risk of visual side effects.  



What Is the Panoptix and Panoptix Toric Lens? How does these lenses work?

FDA approved of The Panoptix® Lens in 2019. This is the first trifocal lens that corrects astigmatism, presbyopia, refractive errors. This lens has been used extensively in Europe prior to FDA approval.  This lens gives focus for near, intermediate, and far distances.

Does Cataract Surgery Hurt?

The short answer is, no. However, you will be awake during our procedure, but take several steps prior and even during surgery so that no pain is felt. You will be heavily sedated and we avoid the use of needles to minimize post surgical complications, such as double vision.

Will You Inject My Eyes Using A Needle?

No, Dr Kenneth Chang has done extensive research on pathophysiology of postoperative diplopia after cataract surgery. The conclusion was that there was a much higher risk of patients experiencing double vision by using injections for anesthesia rather than topical (eyedrops). The details of this study can by Dr Kenneth Chang can be seen here on US National Library of MedicineNational Institutes of Health.


How Much Does Cataract Surgery Cost? Will My Insurance Cover It?


The cost of cataract surgery varies depending on the type of procedure and intraocular lens you decide is best for your needs.


Medicare and most health insurance plans usually cover cataract surgery and ordinary intraocular lenses, but not the cost of premium IOLs that simultaneously correct vision at near and distant ranges. We work with several insurance companies and can the best solution for your situation. Please contact us by phone or when you schedule an appointment for more detailed answers.


What Is The Cataract Surgery Recovery Process?


Many of our patients report clear vision within a few hours after their cataract surgery. However this can be different from person to person depending how your body heals. You should see significant improvement in your vision and the sharpness of your focus within a week or two.


We typically have a follow up visit after your surgery very soon after the procedure, but If you still have blurry vision or if you’re experiencing pain at all before your follow up visit, please contact Dr Chang’s office immediately.


Will I Experience Any Type Of Side Effects After My Cataract Surgery?


With any surgery, there’s always a small possibility of side effects after the procedure. Some of the side effects can be red eyes, itchy, discomfort and even a chance of infection. Even though the chances are slim, we always like to notify our patients of these so they can be aware of it and contact us if necessary.


What Type Of Cataract Surgeries Are There?


Two main types of surgical procedures are in common use throughout the world. The first procedure isphacoemulsification (phaco) and the second involves two different types of extracapsular cataract extraction (ECCE). In most surgeries an intraocular lens is inserted.


Cataract Surgery Complications Are Rare

All surgery has their risks. Fortunately, with favorable outcomes at approximately 98%,cataract surgery is highly successful. There is still potential for serious complications, however, some of which can result in pain, permanent loss of vision, or even loss of the eye. However, this is extremely rare.


Can Cataracts Cause Me To Go Blind?


The scary answer to this is yes, if cataracts are left untreated it cause continual loss of vision, eventually leading to legal blindness or even total blindness. Every situation is different but we strongly suggest getting tested by a cataract specialist like Dr Chang at our Hawaii Kai office to see how bad the cataracts have become and what treatment options are available.
