Q. I slip in a reading lens most days in one eye but prefer it out if doing reading for a day. How do you avoid leaving me with that slight negative one gets of a reading lens in one eye?
A.The eye is like a camera. To focus at different distances one needs to change the focal length of the system. In childhood and youth (those wonderful years) the lens is able to achieve this by changing its shape. The lens is made of the similar material as our hair.From the time we are in the womb, lens material gets added every year. Therefore the lens becomes thicker and more rigid and unable to change its shape and hence the focal length. When our hair grows longer we cut it off. Unfortunately no one gave the lens a shave: that is till now when your's truly will play the role of a barber and shave of the lens using pressure waves;) The non working lens will be replaced by either an accommodating lens or a multifocal lens. These lenses have more than one focal distance allowing one to see far and near.They are made of bio compatible material like acrylic or silicone.

Currently you are using a contact lens to change the focal length. Of course that has its own risks and hassle. Instead an intraocular lens will achieve this. This is NOT like a multifocal contact lens.

Lasik just changes the shape of the cornea and still has only one focal length, whereas PRELEX has more than one focal length

Exciting Times

2009-08-22T06:49:00.000-07:00

These are exciting times, strenuous, economically difficult, challenging health reforms- but still exciting in terms of vision enhancement.
Everyone can finally improve their vision and get rid of glasses which have been compared to crutches.
Yeah one can autograph the crutch and make it glamorous.
When blind can see again is the most exciting moment.
I restored vision in a blind eye. She and her mother were crying with joy. Her sister in Oregon, who is a family physician was amazed. After 50 odd years of not seeing out of that eye, light entered and traveled to the brain. The doc said the books have written its not possible.
That's what we are doing- changing the books one page at a time.
thats why the times are so exciting.

New Technology Allows You to See Near and Far Without Glasses

2009-06-16T12:15:00.000-07:00

If you have undergone cataract surgery, there are three primary methods that can allow you to see near and far. These include:

Monovision
Multifocal Intraocular lens (IOL)
Accomodating IOL

Monovision
This is a process of setting the focus of one eye on close-up objects and the focus for your other eye on far-away objects. In doing this, your brain combines the two images to create a clear picture.

Multifocal IOLs
These include the ReZoom, ReSTOR, and Tecnis lenses. Multifocal IOLs are lenses that have concentric rings of varying focal power, like a bullseye. Some rings provide focus for near objects, others for mid-range objects, and some for seeing objects at a distance.

The Tecnis Multifocal Foldable IOL also has concentric rings for different distances. It received FDA approval in January, 2009 for use in cataract surgery, where the natural lens is replaced. In the clinical trials most participants achieved 20/25 distance vision or better and 20/32 or better for near vision. It is designed using Wavefront data - the same precise level of information that is gathered when you are having Wavefront LASIK.

Accommodating IOLs

These lenses are designed to change focus. An accommodating IOL allows you to see distant objects, and then is can change focus and allow you to see objects that are close up. The only accommodating IOL approved in the United States is the Crystalens.

If you live in the Los Angeles area want to enjoy near and far vision, please contact our Los Angeles office today. Orange County ophthalmologist Dr. Khanna and his staff can help you find the IOL that is best for your condition and needs. Please call today to schedule your free vision screening.

Signs and Symptoms of Presbyopia

2009-05-28T07:38:00.000-07:00

As you grow older, you may find that is more difficult to read, use the computer and focus on near objects. The reason is presbyopia. This is a medical condition where people begin to lose the ability for their eyes to focus.
The earliest warning signs can be seen between the ages of 40 and 50, though some experience symptoms years before.

Difficulty reading and blurred near vision are two of the most common signs of presbyopia. Some individuals may also experience headaches and eye fatigue as well.

The most common symptoms include:

Hyperopia, or farsightedness. Objects at a distance are clear, but objects close up are blurry
Far-sightedness increasing with age
Difficulty focusing on nearby objects
Difficulty reading
Experience eyestrain or headaches from prolonged reading or close work
Holding books or magazines at a distance to read clearly

If you or a loved one is exhibiting the early signs of presbyopia, it is important that you contact our Orange County Office as soon as possible so that your condition does not worsen. We offer free vision screenings for all new patients. Please schedule your appointment with Dr. Khanna today.

I hate Contact Lenses and here is why:

2009-04-29T11:02:00.000-07:00

One often faces many problems being a contact lens user. Dry eyes, irritation, and blurred vision are just a few of the inconveniences that wearing contact lenses can bring. Not to mention the hassle of having to worry about always carrying an extra pair on you and having to remove them periodically and clean them. Wearing contact lenses eliminates the need for uncomfortable and bulky glasses, but it brings a lot of difficulties as well.

For someone who wears contact lenses, they are constantly reminded that they have a foreign object on their eyes- ouch :(. For a college student or for someone who works in an office setting, staring at a computer screen all day can cause dryness and tiredness. The dryness causes one's eyes to become red and watery, and can lead to headaches. And the tiredness causes one to have to frequently take a break. Eye drops help in these situations, but they only provide temporary relief. This affects one's productivity because they are not able to function as well or as effectively as they should be able to.

Another problem which contact lenses bring about is blurred vision. This happens sometimes when the contact lens gets dirty or when it becomes too dry. This can cause much inconvenience and can be dangerous in situations such as driving a vehicle. Imagine having to drive at night with blurry contacts, this can be a great risk and can put your own life and other's lives in danger. Sometimes taking the contacts out and cleaning them does not even help. One must throw the pair out and get a brand new pair, which can become expensive if the problem keeps reoccurring.

For a contact lens wearer, another worry is always having to have an extra pair of contacts or glasses on them as well as cleaning solution and eye drops. For someone who relies on contacts to be able to see, they cannot take the risk of not being prepared if one of their contacts falls out, or if it becomes too blurry to see, or if their eyes get too dry. Therefore, they always have to carry these items with them. This is an inconvenience for everyday life, not to mention when travelling.

Have you ever played football with contact lenses? Having my contact lenses fly away on a tackle and than not knowing where to run was embarrassing and frustrating.

Contact lenses are supposed to be a more convenient alternative to wearing glasses, but they bring about many problems from dryness to irritation to blurred vision and much more. With all of these problems, wearing contact lenses can be very uncomfortable. Always having to worry about your contact lenses is not a convenient way to live one's life. For someone who wears contacts, they are always reminded of it and it is a fact they cannot escape. For these reasons, I hate contact lenses! Wish there was a solution... Hmmmm...

Yes there is, LASIK performed by a skilled and well trained surgeon using the safest technology.

Prelex

2009-04-07T09:25:00.001-07:00

Advanced technology, PRELEX can restore vision. This 21^st century technique is the wave of the future. PRELEX is better and longer lasting than LASIK. This recently FDA approved technology has granted vision to Gwendolyn Hayes, a legally blind woman slowly getting the light extracted from her vision. Gwendolyn is now able to read and write without glasses, seeing for the first time in 40 years. She describes it as a 'miracle'. "Other doctors told me there was nothing they could do. I was heading towards blindness. Then I came to Dr. Khanna. Dr. Khanna not only restored my vision, but it's better than I ever imagined." This was possible through the cutting edge technology of PRELEX combined with crystal lens High definition. PRELEX is a safe 10 minute procedure using custom designed restore 3D or Crystalens HD implants inside the eye. Gwendolyn can now see far and near in each eye. This has allowed her to continue and improve her daily activities and maintain her independence. The crystalens implants work with the eyes natural muscle to accommodate near, immediate and distance subjects. This preserves your binocular vision and depth of field. Crystalens comes closest to mirroring the functions of the natural lens. Gwendolyn says "I want to spread the message and let others know of his [Dr. Khanna] great works, that is my mission in life."

EpiLASIK for Dry Eyes

2009-03-16T15:34:00.000-07:00

Tears bathe your eye and wash out dust and debris. They also help keep your eye moist and contain enzymes that are essential for good eye health.

If you are suffering from dry eye syndrome, your eye either does not produce sufficient tears, or has a certain chemical composition that causes your tears to dry up too quickly.
Those who have poor vision and are considering LASIK surgery, it is important to note that dry eyes can occur both before and after this procedure. Dry eyes may be aggravated in patients who had the condition prior to their surgery.

Dry eyes are less common

Surgeons who use epiLASIK have reported fewer instances of dry eye syndrome as a complication. One reason may be because the thinner corneal flap does not impede the normal processes of the corneal nerves that trigger the responses necessary to moisten your eye's surface.

EpiLASIK differs from LASIK because of the type and thickness of the corneal flap. The flap cut is so thin that it does not penetrate the actual cornea substance, only its outer layer, known as the epithelium. An epithelial separator is used to separate the epithelium sheet from the eye. Because epiLASIK does not actually penetrate into the superficial layers of the cornea like LASIK does, it is less likely that you will develop or worsen dry eyes with this procedure.

If you or a loved one lives in Los Angeles and is suffering from dry eyes, please contact our office today to schedule your free vision screening today. Orange County ophthalmologist Dr. Khanna can help you find the treatment to alleviate your dry eyes and get on with your life. Please call today.

Differences in Types of Intraocular Lenses (IOLs)

2009-02-25T15:25:00.000-08:00

Intraocular lens (IOL) implants are used to correct poor vision, whether it is clouded by cataracts or blurred by presbyopia.

With this type of surgery, your eye's natural lens is replaced by an intraocular lens implant. A monofocal intraocular lens may be implanted to give you a clear point of focus, at a distance or close up.

Types of Multifocal IOLs

Because of their ability to correct vision at all distances, multifocal IOLs are the most preferred IOLs. There are three main types:

Multifocal refractive

Multifocal refractive IOLs, like the ReZoom, are crafted with several optical zones on the intraocular lens. These different zones allow for various focal points, which improves your vision:

At a far distance
At intermediate distances
At near distances

Apodized diffractive

Apodized diffractive IOLs, like the ReSTOR have gradual diffractive steps on the implant that creates a smooth transition between focal points. This IOL also bends incoming light to the multiple focal points, which enhances vision in different light conditions. Acrysof has recently improved the optical properties of its ReSTOR lenses and released a new version, known as ReSTOR +3.0D. The Khanna Institute is proud to offer this new lens which achieved patient satisfaction rates of 95 % in clinical studies and gave a fourfold increase in the number of patients achieving 20/20 vision or better.

Accommodative

A newer type of IOL, the accommodative, includes lenses such as the Crystalens. These IOLs have one focal point, but act like your natural lens, changing shape to move the single focal point to bring objects at varying distances into focus. Recently, Bausch and Lomb introduced Crystalens HD, which improves depth of focus to improve near vision while maintaining high quality intermediate and distance vision. Khanna Institute of LASIK & Refractive Surgery is proud to offer this new option to our cataract and presbyopia patients.

If you would like to make permanent enhancements to your vision, please call our office or schedule your appointment online today. Orange County ophthalmologist Dr. Khanna can discuss your options with you during your free vision screening.

New IOL Technology

2009-01-29T13:24:00.000-08:00

The Khanna Institute of LASIK and Refractive Surgery is proud to announce it is offering the newest version of Acrysof's ReSTOR intraocular lens (IOL), the Acrysof ReSTOR +3.0 D. The ReSTOR +3.0 D received approval by the Food and Drug Administration on December 23, 2008 for the correction of presbyopia in cataract patients. In clinical trials, the ReSTOR +3.0 D achieved a superb patient satisfaction rate, with 95 % of recipients saying they would have get the lens again. Nearly four times as many patients achieved 20/20 vision with ReSTOR +3.0 D as with previous versions of the ReSTOR lens.

When the natural lens in one or more eyes becomes cloudy with cataracts, the only available treatment is replacing the lens with an artificial lens. Early replacement lenses only allowed recipients to see clearly either up close or at a distance, but ReSTOR and other advanced IOLs can give patients a full range of vision following surgery. The ReSTOR lens can also be used to correct presbyopia, a condition that affects many Americans aged 40 and older, typically requiring the use of reading glasses or bifocals. Because of its superior optical qualities, the ReSTOR lens offers the chance for people to continue performing all their day-to-day tasks without the use of reading glasses or bifocals.

To learn more about the ReSTOR +3.0D or other treatments for cataracts and presbyopia, schedule a refractive surgery consultation today.
