symphony toric presbyopic implant


Symfony toric is a new premium intraocular lens to correct astigmatism. It is manufactured by Johnson and Johnson, the same company which also makes Band Aids.

actual sizeThere are about 4 million cataracts surgeries that are performed every year and more than half of Americans have undergone cataracts surgery by the time that they are 80 years old. It is not only a condition that treats older people, but it can occur in the eyes of any human being. Similar surgeries are done in people who suffer from presbyopia, astigmatism, and other problems people may experience with their vision. These surgeries are not necessarily painful, but they do cause some discomfort. However, there is a new way in which patients can look forward to crisp vision after the surgery.

Symfony Toric is FDA approved

The Symfony Toric contact lens has been approved by the FDA recently and shows that it can help with any of the above problems. Doctors have recommended it to their patients following their cataract surgery in order to help them enhance their recovery and vision. It is especially helpful for those who suffer from presbyopia. The lens returns the sense of freedom and independence to the patients and allows them to continue with an active lifestyle without having to wear glasses.

During a cataract or presbyopia surgery, the lens of the eye is removed and an artificial lens, or IOL, is inserted into the eye. The IOL is usually a monofocal lens which only allows patients to see objects at a distance. The result is then that objects that are closer are out of focus. The Symfony lens is developed in such a way that both the objects at a far distance and those at a closer distance can be seen perfectly. It improves the range as well as the quality of vision in patients. Those who have had the Symfony implanted in their eyes have proven to have more successful results than those who have the IOL implanted in their eyes.

Lens Implant

The Symfony lens has been approved by over 50 different countries worldwide and is also available in the United States of America. It has been clinically tested on over 2,000 eyes and these are the results that have been returned:

  • Provides seamless, day to day vision: the patients with the Symfony lens showed that their vision has improved and that they could see objects that were far away, objects that were at intermediate distances, and objects that were close to them. They could also see different points in between and they reported clearer and sharper vision.
  • Symfony Toric provides high-quality vision: in contrast with the IOLs, the Symfony does not leave the patient with an inability to focus. The reason for this is because the Symfony is specifically engineered to capture the wavelengths of light at the right spots as it hits the lens. It also moulds to the shape of the cornea for improved vision.
  • Symfony Toric has a resistance against halo and glare: the Symfony has reduced the chances of bright glows around bright lights, enabling the patient to see better without disturbances. This allows the patient to drive and see better at night time.

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!

Femtosecond Cataract Surgery

Femtosecond Cataract Surgery is a recent advancement.

Of all the types of surgeries performed, cataract surgery is the most common with approximately 19 million people undergoing the operation each year worldwide!  In the United States it id the most commonly performed surgical procedure. Femtosecond cataract surgery is an attempt to remove cataracts with more precision making it safer due to the precision of laser technology.

Patients undergoing Femtosecond cataract surgery may have their operation without the need for blades at all. The whole procedure is done through a small incision the size of a pin to remove the cataractous lens restoring vision.  The features of femtosecond lasers include:

  • Imaging in real time that also has integrated OCT, this will allow for the eye to be seen in 3D throughout the operation.
  • Patients can expect a more comfortable experience due to the curved patient interface and performance of the special laser.
  • Because every patient is different the touch screen interface allows ease of set up for the user to plan the operation in advance so that the surgery can begin sooner and with greater ease.
  • The location, size and even shape of the small incision can be planned beforehand giving greater control over the surgery and of course better results for all patients.

Femtosecond Cataract Surgery

Before Femosecond cataract surgery was offered to the public it first underwent numerous studies. The studies showed the technique to be both safer and more effective than traditional methods. By introducing such precision to the operating room, the success rate has been increased immensely. Even the densest cataracts can be liquefied with little effort and less chance of damage to the eye itself.

As the equipment is able to take and create an image that is 3 dimensional it can give such precise results that it can take as little as few seconds to dissolve the cataract without a single cut . It is the first of its kind and has been deemed to be a safe method of removing cataracts to date.

Lensx , Catalys, Lensar and Victus are FDA approved.

Advantages of  Femtosecond Cataract Surgery

The precision of this innovative technique has many benefits over traditional cataract surgery.

With traditional cataract removal there have been cases where tears have occurred to the anterior capsular which can lead to permanent sight loss or reduced sight. In cases where the cataract has been allowed to get worse over time (especially when waiting on long lists has occurred) it can be difficult to remove the cataract traditionally. Even in cases where the cataract is older and hard, Femtosecond cataract surgery is able to chop it with better results and faster recover time for patients. As the size of the capsulotomy remains consistent there is also a reduced chance of the lens being in the wrong position. Femtosecond lasers are an advantage in traumatic cataracts too.

A word of caution. Recent studies have shown that the laser may not be needed in all situations. In many eyes, experienced surgical hands can give better results. So judgement has to be applied.

As the amount of people being seen with cataracts each year is on the rise the waiting list for surgery and ultimately the waiting time can be shortened significantly.

What is Glaucoma?

Glaucoma is high pressure in the eye. This pushes on to the optic nerve fibres leading to their destruction. These nerve fibers are responsible for vision. Loosing them leads to defects in the field of vision. The most common cause for the rise in pressure inside the eye is blockage of the drainage channel. With nowhere to exit the fund builds up inside the eye. This is like a blocked drain leading to overflow of the basin.

Glaucoma can be followed for progression. It can be by subjective test like visual field. We have one of the latest windows based machine to help you do this test easily. This latest generation of machine can also track changes in changes in your visual field.

Cataract Surgery After LASIK

Cataract Surgery After LASIK

Cataract Surgery After LASIK eye procedure requires special expertise. There are many important points to think about. Lets divide the factors to consider into three groups. Calculations before Cataract eye procedure, Techniques during the cataract surgery and management after the cataract eye surgery.

Calculations before Cataract eye procedure

Its very important get certain data before proceeding with cataract eye surgery.

  1. Length of the eye: This can be measure by ultrasound or laser. Laser detection with Iol Master or Lenstar.
  2. Curvature of the cornea: This is where the fun and headaches begin. Lasik eye surgery changes the relationship between the front curvature of the cornea and its back curvature.
  3. Power of the cornea: Detecting the true power of the Cornea is the holy grail of determing Iol power for emmetropia in patients undergoing cataract surgery after lasik eye surgeries.
  4. Distance between cornea and the lens: Also known as anterior chamber depth.

Techniques during the cataract surgery

The style of removing the cataract and inserting the new lens.

  1.  Laser Or Manual Cataract Surgery: Will laser make corneal incisions too close to the flap?
  2. Type of Implant – Monofocal or PIE: We need to to asses the optical zone on Corneal topography. Corneal pachymetry map needs to be evaluated.
  3. Which PIE will work best for that eye: Crystalens or Tecnis multifocal could be an option. Some patients have loved the Restor.

 Management after the cataract eye surgery

Correcting the residual refractive errors by laser or limbs relaxing incisions may be required. Aggressive management of dry eyes is essesntial.

Cataract Surgery after Lasik eye surgery

LASIK eye surgery involves reshaping your cornea to correct a wide range of refractive errors – providing you with clear, sharp vision that either eliminates or greatly reduces your dependence on glasses and contact lenses. However, LASIK cannot prevent the development of cataracts later in life, since cataracts are a problem with the eye’s lens, not the cornea.

Because LASIK involves reshaping your cornea, you will need to consult with an experienced eye surgeon before undergoing cataract surgery in the future. Once your cornea is reshaped during LASIK, your cataract surgeon will need to perform a careful examination in order to determine the correct degree of power needed for your intraocular lens (IOL) – the artificial lens that is implanted during cataract surgery.

If an inexperienced surgeon takes the incorrect measurements, your vision may become out of focus following cataract surgery, requiring additional procedures to restore ideal vision. Thankfully, Dr. Khanna’s extensive experience with both LASIK and cataract surgery has equipped him with the skill necessary to accurately evaluate the changes in your eyes caused by LASIK surgery, ensuring the best possible vision with your IOL after cataract surgery. After removing the cataract, Dr. Khanna will perform a manifest refraction to determine the appropriate lens power for the IOL. Based on this information, the correct IOL will be implanted. You can read more about this topic in the bestseller book on cataract surgery.

Windmill Technique – Latest Cataract Surgery Method

Windmill Technique – Latest Cataract Surgery Method

We know that phakoemusification or cataract surgery using ultrasound is constantly evolving. This is done with an eye towards safety. as cataract surgery has evolved it has decreased occurrence of problems. The incidence of infections has been the most important chapter in modern cataract surgery. Decrease in breaking of the posterior capsule of the lens bad has been a feather in the cap of top cataract surgeons.

Windmill technique: This new technique has been published in the Journal of Cataract and Refractive Surgery in 2014. The authors display a new safer method of lens removal using minimal energy. They employed an Infiniti Ozil apparatus system. Instead of first breaking the centre part of the lens into multiple pieces they go after the soft part first. They churn the softer outer part utilizing oscillations of hand piece. Than they liquify the central hard part of the lens. This avoids the sound energy traditionally used. It also has the advantage of working away from the cornea. Windmill Technique – Latest Cataract Surgery Method, also prevents small pieces of lens from flying around and keeps a safe distance from the posterior capsule.

Windmill Technique – Latest Cataract Surgery Method works best with softer lens- Grade 1 and Grade 2 .You may be aware that cataracts are graded based on their firmness from Grade 1 to Grade 5. Grade 5 being the hardest thickest lenses. They may be white, red or even black in color. Grade 1 are the softest and usually grey or white.

It is a good idea to discuss with your cataract surgeon the various types of latest techniques he is skilled in. There is no harm in seeking a cataract surgeon who knows various approaches to eliminate the cataracts.

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.
