What is the Symfony IOL?

Up until recently, if you wanted to fix your presbyopia (age-related long-sightedness) you would need to get a Multifocal IOL (Intraocular Lens). The problem with a Multifocal IOL is that to be able to additionally improve your reading vision your distance vision would suffer. You would have to decide whether you would rather have better distance vision and still need reading glasses (Monofocal IOL), or if you would rather have slightly better distance and good reading vision (Multifocal IOL). You also had the option to get a Monofocal IOL in one eye and a Multifocal IOL in the other, so you could have at least one strong distance eye. Enter the Symfony IOL.

The Symfony IOL is the first and only extended range of vision IOL that corrects presbyopia. This means, that unlike the Monofocal IOL that only allows you to correct distance vision, or the Multifocal IOL that allows you to correct both but with a compromise in your distance vision, that you can now correct both without loss of quality. It also comes in a Non-Toric and Toric version for patients with astigmatism! Another added benefit of the Symfony IOL, which the Multifocal IOL had a problem with, is that there are no glares or halos with this lens, making your newly corrected vision even better!

Implanting the Symfony IOL

 The Symfony IOL is implanted during a routine cataract operation. Completed with minimum recovery time, most patients are able to go back to their normal lives within 24 hours. With a routine operation, minimal recovery time, and improved distance and reading vision without glares or halos, the Symfony IOL sounds like a great choice!

Bifocal Implants – A Breakthrough from Monofocal Lenses


Bifocal Implants – A Breakthrough from Monofocal Lenses

Cataract surgery done these days is good and safe. The surgery can even be finished in less than 20 minutes on top of a very short recovery period requirement. This attracts most people with cataract to have cataract surgery. Unfortunately, despite these advancements, a major downturn is that the treatment by insurance only uses monofocal implants, which means that only a single point can be focused. If this is the case, the patient will still be required to use correction glasses to help make their vision a lot clearer.

Bifocal Implants

Monofocal implants were used before in making clearer vision for patients, but by the last few decades, a new implant known as bifocal was introduced. This means that the lenses are multifunctional, which also indicates that the patient can focus different distances already and do all things independently after the treatment. Infact I inserted bifocal implants in the early nineteen nineties. Thats over two decades of experience implanting sight improving intraocular implants. These bifocal implants were manufactured for the first time by the company Shah and Shah.

The bifocal implants lenses are beneficial for people who do not want to depend on glasses and have reached an age over 45. This is different from the LASIK surgery because the latter does not require implants. Lasik eye surgery does not require a sterile surgical suite; but instead performed in a clean laser suite

There are three different types of FDA approved bifocal implants lenses and they are called Tecnis, Restor, and Crystalens. You must know what these types of lenses are as well as what their differences are before agreeing on what type of surgery has to be done for you. The discussion must be done by the surgeon who will do you the surgery. A good source of information for these bifocal implant lenses is this book on cataract surgery. You must not rely solely on the advertisements you can see in the media since some aspects might not be discussed thoroughly.

Your decision in choosing what type of lens to use for your cataract procedure might then be affected by the cost associated with the implant types. This is because only few insurance providers cover these types of services and lenses, so therefore you may need to look at your finances and available options of monthly payments.. At our Cataract eye center, of Thousand Oaks, we offer patient lens implants based on what people with fixed income can afford and what they desire in regard to vision correction. Out Top Cataract Surgeon makes sure to offer the most appropriate up to date technology in cataract surgery and provides an array of lens options for each patient.

Instances That Suggests You to Have Cataracts

Instances That Suggests You to Have Cataracts

Having an eyesight problem like cataract can surely be a hassle, as it will not allow you to do more things that require clear vision. If you want to get back your life before you have cataract, you should look for a surgeon and make an appointment for cataract removal treatment immediately. You must not wait until it gets worse. If you are not sure yet whether you already need treatment, here are some of the Instances That Suggests You to Have Cataracts.

Eyesight Changes Too Often

Have you experienced times wherein you need to change your eyeglasses often because the recently prescribed eyeglasses do not fit your current needs? Maybe it is time for you to stop relying on eyeglasses, as it will just cost you a lot of hassle over time. It is best to look for a doctor and have a cataract surgery immediately. Inconsistent eyeglass grade necessity is a symptom of cataract.

Poor Overall Vision

You must understand that having an unclear vision does not immediately suggest you will need to have cataract surgery since some individuals might just need correction glasses. However, if you notice that even with using eyeglasses you still cannot see clearly, especially at night, you must see a doctor immediately. Not all people show the same cataract symptoms, so you must be aware of what is happening with your own eyesight.

The Color You See Fades

You must take note the at times individuals can see color differently from other individuals. Commonly, doctors perform a test to determine this by examining two patients. The doctor will show a image and if you cannot state what the real color is, you may need to be subjected to cataract removal.

Double Vision

Cataracts are notorious in causing multiple images. This may lead to difficulty in perceiving the right image. Seeing double of an object is termed as diplopia. Cataracts cause monocular diplopia – that is when one eye is covered the other still sees two objects

Difficulty driving at night

When driving at night cataracts can cause difficulty causing glare, haloes, and decreased overall vision. If you have difficulty with light at night or see glare and haloes this may be cause for a cataract removal. Glare and Haloes may not be solely due to cataracts so a exam with an ophthalmologist is required to find the correct cause.

Extra light to Read (Forget those Menus)

Cataracts can cut off incoming light into the eye, preventing the light from reaching the back of the eye. Therefore you may notice you require extra light when reading your favorite book in bed or menus in restaurants.

Having all or any of the symptoms above might alarm you, as those are the symptoms of patients who need cataract removal. Hence, do not be hesitant in calling up an appointment with your doctor as early as possible. Dr. Khanna of Khanna Vision Institute, serving Los Angeles, has performed cataract removal on thousands of individuals including his own mother. Cataract surgery is a common procedure and can be performed safely and easily with the correct surgeon.
No more cataracts with Khanna Vision Institute!

Possible Complications of Cataract Surgery

Possible Complications of Cataract Surgery

By Rajesh Khanna MD

a member of American Society of Cataract and Refractive Surgery

Cataract surgery is a type of operation that has been around for decades now. This is deemed as one of the safest surgeries there is. The success rate of cataract surgery is at 98% as per the American Society of Cataract and Refractive Surgery . However, no matter how safe a procedure is, possible cases of complications of Cataract Surgery still arise. Though these complications may be of minor ones and can be easily corrected, knowing them would still be best so you may prepare in case they happen.

Possible Complications of Cataract Surgery

  • Infection and Bleeding – these two are common complications that can happen in surgeries and cataract surgery is no exception to this complication.
  • Posterior Capsule Opacity – this is one of the most common complications of cataract surgery. This side effect happens when the lens capsule protecting the eye lens grows cells from the outer layer of the cornea onto the capsule. This will then result into a hazy vision. Nevertheless, a laser treatment procedure can correct this. This complication may happen in 20% of cataract surgery patients.
  • Double Vision – Double vision happens when the implanted intraocular lens gets out of place or dislocated. This can be treated by your eye surgeon by re-positioning your dislocated lens. If the dislocation happens again, this can be corrected by sewing the lens in place.

Other Cataract Surgery Complications – other complications following a cataract surgery may include, but is not limited to the following:

    • Droopy eyelid or swelling: More common with prolonged surgeries using a speculum to pry the eye open.
    • Decreased vision or Cystoid macula edema. Found more often with Surgeons using a high level of illumination directly focussed on the eye
    • Retinal detachment : A curtain coming in front of eyes. Highly nearsighted people are more prone to this
    • Dislocated lens material: In cases of complicated surgery
    • Pain : from the increase in intraocular eye pressure
    • Redness : If conunctival tissue has been tampered with by the cataract surgeon
    • Light Sensitivity – multifactorial

Cataract surgery complications, like the ones mentioned above, should be reported immediately to your doctor as soon as you notice them. One reason for this is because in just a few weeks or months post-surgery, the implanted lens can grow in place. This will then become a lot harder for your surgeon to remove or reposition.

Beverly Hills Presbyopia Treatment Options

Everyone will experience presbyopia as they grow older. This universal eye disorder causes your eye’s natural lens to lose its flexibility, making it difficult to focus on objects up close. If you are currently using reading glasses or bifocals, you may be interested in some of the more permanent presbyopia treatment options that are now available.

Our experienced Beverly Hills ophthalmologist Rajesh Khanna, MD offers three main forms of presbyopia treatment:

  • Presbyopic Lens Exchange (PRELEX) – This revolutionary refractive surgery corrects presbyopia by replacing your aging natural lens with a new artificial lens. There are many different types of intraocular lenses (IOLs) available designed to treat a wide range of refractive errors, including myopia, hyperopia, and astigmatism.
  • Conductive Keratoplasty (CK) – Conducive keratoplasty uses radio frequency energy to steepen your cornea, allowing light to focus properly on your retina for clear near vision. CK can free you from your dependence on reading glasses or bifocals.
  • Monovision – Using LASIK technology, the cornea of one eye is adjusted for near vision, while the dominant eye is adjusted for distance vision.

There is no reason you should resign yourself to using reading glasses or bifocals for the rest of your life. Today’s presbyopia treatment options make it possible to enjoy clear vision at all distances again, freeing you to do and enjoy more on a daily basis.

To discuss presbyopia treatment in more detail, please contact The Khanna Institute today or call (888) 339-8143 to schedule a consultation with our experienced Beverly Hills eye doctor. We serve patients in Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.

New Technology Allows You to See Near and Far Without Glasses

If you want to undergo cataract surgery in 2014, there are three primary methods that can allow you to see near and far. These include:

  • Monovision

And the new technology

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. This is a relic from the twentieth century. Primary disadvantage is one looses binocular vision.

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. This was true in 2005 and is still true in 2014. We even have toric crystalens called trulign.

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

Signs and Symptoms of Presbyopia

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.That is when the need for readers and cheaters starts. Gradually the dependance increases.

The most common symptoms of Presbyopia 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 Ventura or Los Angeles 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.

Differences in Types of Intraocular Lenses (IOLs)

Differences in Types of Intraocular Lenses (IOLs)

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 Intraocular Lenses (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 Tecnis 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.


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. Ventura County ophthalmologist Dr. Khanna can discuss your options with you during your free vision screening.
