Symfony or Tecnis Multifocal lens for Presbyopia Treatment

Today our topic of discussion will be Symfony or Tecnis Multifocal lens for Presbyopia Treatment.

Hi. I am Doctor Khanna, here with some models of intraocular lens implants when we do cataract surgery or we want to get rid of glasses and you are not a candidate for Lasik surgery. For example, if you are 56 years old and you want to be able to see far, middle and near, then you are up for presbyopic implants. There are different types of presbyopic implants. Today, we are going to talk about the differences between ‘Tecnis’ and ‘symfony’, which are both from Johnson and Johnson.

This is how the lenses look like. This is a clear lens and this is ‘Tecnis’ and ‘symfony’. ‘Symfony’ has less rings than ‘Tecnis’ and it is considered an EDOF (extended depth of field) lens. Whereas, ‘Tecnis’ has certain ridges, which splits the incoming light into distant and near. You can see distant and near and the bimodal curve, lets you see middle. ‘Symfony’ acts like a pin hole camera where you can see middle, distance and somewhat near.

How are you going to choose between the two? If you have long hands, then choose ‘Symfony’ but if you want to real closely then choose ‘Tecnis’. If you have had previous surgery like radial keratotomy then ‘symfony’ might be a better choice. In terms of side effects, ‘Tecnis’ has glare initially which faded away and ‘Symfony’ you can see a spider web. The best option is to discuss these various choices with your surgeon and to make sure that the surgeon is comfortable with the choices.

Have a wonderful day.

7 Myths Cataract Surgery

Hi folks. This is doctor Khanna, your laser eye man. Coming to you with some new information. Today, I am going to talk to you about the 7 myths of cataract eye surgery. Cataract surgery has been there for many ages. You have probably heard about it but what is interesting is that your grandparents have probably heard about it. Even their grandparents knew about cataract surgery. Over the years, cataract surgery has advanced so much. The surgical finesse has become so much better that the modern day cataract surgery is way ahead the cataract surgery that was performed 60-70 years ago.
The problem is all the new information and knowledge has not circulated to the masses. Most of the information from decades old technology is still circulating amongst our friends and relatives. Today, I want to destroy all these myths, which are still existing.

MYTH 1 Cataract Surgery You have to wait for cataract to get ripe before they can have surgery.

This might have been true around 60 years ago when we did not have microscopes, surgical lubes and stitches. We did not have modern technology to pulverize the lens and take it out through small openings. At that time, the only to take it out was when you could see that the cataract is white, red or black. Freeze it and then pull it out in mass. Over the years, we have developed surgical loops, microscopes to binocular microscopes and we can see the smallest things in there. We can make minute openings, go in there and remove lens, which might not have been visible to the naked eye. That is the first myth that we have to destroy totally. In fact, the opposite is true. You should never wait for the cataract to get ripe because as the cataract matures, it gets hard and requires more energy to be taken out. Why is so much energy bad? It is because we are in a closes space in the eye and the energy is going to hit the iris (the colored part of the eye), the cornea (the clear front part of the eye) and damage the cells. We want to avoid that. The first myth has been dismissed.

Myth 2 The doctor has to decide when you need cataract surgery. 

This is news from a by-era when the doctor has to see the cataract and he was comfortable with the surgery. Today, it is all about you. Even Medi-care, medical insurance and everybody says that. The best time to do cataract surgery is when you feel that the cataract are bothering you and interfering with your active lifestyle. For different people it might be different. If you are 52-years old, and you have cataract that cause a lot of glaring driving, it might be troublesome for you and you might an early intervention. If you are a librarian or a stay-at -home person who does not drive a lot, then those minor cataract might not cause a lot of difficulty to you. You get to decide not the doctor or the insurance.

Myths Cataract Surgery  #3 You cannot go blind with cataracts.

It is important because many people are fearful of cataract surgery. They feel that the surgery will harm them and that cataracts are not going to cause any problem in the long run. That is wrong because the cataract is hardening and changing the lens and it gradually keeps cutting off the light until there is no light. You would be surprised to know that cataract is the most common preventable cause of blindness in the world. When the cataract hardens, it can lead to increased pressure and inflammation leading to blindness. The third myth that cataracts cannot make you go blind has been busted. You should do everything at all cost to avoid it.

Myths Cataract Surgery #4 The cataract has to be removed entirely.

This was the in the 70’s when the cataract had to be taken out in mass. That is not true and in fact, the opposite is true. We do not want to take out the entire cataract. We take out the cataract bag, clean out the contents and put in a new synthetic lens using the old lens as a support of the new lens. If you do not do that, the new lens would fall down and you do not want that. It is like taking your car for an engine oil change, out comes the old and in comes the new. You do not change the whole cask of the engine itself.

Cataract surgery is painful. Myths Cataract Surgery #5

This myth is close to everybody. Today, it is not true. Today, cataract surgery is one of the simplest and easiest procedure to perform. We keep it pain free both by topical drops and specially formulated drops that are instilled inside your eye. We make sure that your eye is numb and is pain free. We do not have to numb your whole body.

Myth #6 You have to be put out during cataract surgery.

If we are operating on your eye, we do not have to numb the whole body. We can take care of the pain.

#7 Myth Cataract Surgery
Recovery is long and painful. That is not true. Why? It is because it is a simple surgery performed in a short period of time for about 7-10 minutes. You are pain free and not totally asleep. Many people can go and work or even drive the same day if we do not give them enough medications. That is not what we are recommending. It is not like before when it was six weeks, in a day or two, you can go back to your activities of daily living.
I hope this information is useful and we have destroyed these 7 myths for now and forever. Thank you and have a wonderful day.

Myths-Laser-Cataract-Surgery

Hi. How are you? This is doctor Khanna, laser man here once again, bringing you up to speed with the latest in eye technology. Today, we are going to talk about a very exciting and new topic; laser cataract surgery. There are a lot of myths about laser cataract surgery and we are going to bust them all. We are going to talk about 7 myths of laser cataract surgery, which has been found not to be true and we are going to go over it one-by-one.
Laser cataract surgery is safer the manual cataract surgery. Even doctors believe that but reports came out of a study that showed that it was not the case. Laser surgery is at best as good as manual cataract surgery but not safer. That is one myth, which has been busted not by me but by published and reviewed journal studies of Europe.
Laser cataract surgery is going to be free and covered by insurance. That is not true. Medical insurance has determined that if someone wants to upgrade to laser cataract surgery, they will have to pay extra.
Laser can perform all the steps of cataract surgery. I think that is one of the biggest myths out there, thinking that it is going to be a robotic surgery and robots are going to come and do everything. That is not true. Lasers do certain steps pf the procedure, mainly opening in the lens and sometimes cutting the lens. They cannot do all the steps. In fact, some steps are done better by hand.
Cataract wounds made by lasers are better than those made by diamond knives. The reverse is true, diamond knives can make better and more precise wounds than the current generation of lasers used in cataract surgery. It is very logical why this happens, because the laser will need to see where they have to act. They are seen by using ‘ocular coherence topography’. The wounds have to made at the junction between the clear part and the hazy part which is the cornea and sclera. It is sometimes not discreet for the machines and that is why human eyes can detect them better and make better wounds.
If we do laser cataract surgery, we would not have to wear glasses after the procedure. That is not true. Only ‘presbyopic implants in eye’, can free you from the bondage of contact lens and glasses after cataract surgery and not laser.
After cataract surgery, drops will not be needed. Again, that does not hold the light of day. You will need drops. Drop less surgeries is a different concept. After the laser cataract surgery, you might need more drops.
Laser cataract surgery might be less painful and faster by cataract surgery done by hand. I feel sorry but, we have to bust that one too. When we do laser cataract surgery, we have to apply something that would hold your eye while the laser moves around making the openings and cutting the lens up. That is held by negative suction pressure, which is painful and we have to give you medication for that. For that, we have to add another step, we have to do the part of the surgery done with laser first and then in the operative room, we have to do the rest of the surgery by hand. It increases the time that you would be in the operating theater.
I hope you have seen the truth about laser cataracts surgery. It is a good procedure but it is not recommended for all based on knowledge and published studies that we have. Thank you for listening to me. Have a wonderful day. Keep sending your questions here.

What is Cataract Eye Surgery?

A method to enhance vision by removing the natural lens which turns hazy and in many cases opaques. In the past (and maybe still in some third world countries the lens was removed in toto. Currently in Los Angeles, USA the most common is to open the natural lens and remove only its contents. Dr. Khanna replaces these degenerated lens fibers with state of the art biocompatible synthetic lens implants. So it is similar to an engine oil change. Out with the bad and in with the good. It is vey important to remember that Dr.K does not like to replace the entire lens. Keeping the outer covering of the lens intact allows him to place the artificial new lens in a natural stable position. If the entire lens were to be removed there would be no support for the replacement implant.

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!

Risks and Problems Associated with Visian ICL

Risks and Problems Associated with Visian ICL

Visian ICL is probably the most advanced technology present in the market today for vision correction. However, as with any other medical procedure, its benefits do not come without risks. There are a few possible Visian ICL problems that patients may encounter as well as have to be aware of:

Overcorrection and Undercorrection

Although a skilled surgeon makes use of the 3D advanced technology to make measurements before surgery, the measurements are not always perfect. Therefore overcorrection and undercorrection can occur. Similar to other refractive procedures, undercorrection in Visian ICL can be fixed with an additional procedure or with continued use of prescriptive eyewear.

Infection

Infection is not a very common risk or problem but since the procedure involves a small form of manipulation there still is a slight risk of eye infection, which could in turn delay the healing process.

Night Glare and Halos

Halos and night glare are the most common side effect of any refractive surgery. Visian ICL patients may still experience night glare and halos but the cases are less compared to those who have Lasik.

Damage to Crystalline Lens

Because Visian ICL is positioned inside of the eye, there is a potential risk of it touching the natural lenses. This could result to less opacity of the lens and in extreme cases it may lead to the need to replace the natural lens with synthetic ones.

Iridotomy Complications

The process of iridotomy or making a small opening near the edges of the iris using a laser is done during Visian ICL. Although complications from iridotomy are very rare, it could also lead to inflammation, corneal damage, scar formation, and intraocular
pressure increase.

Pressure problems

Sometimes the new lens inserted in the eye prevents the movement of fluid. This leads to an increase accumulation of the eye fluid behind the colored part of the eye. This can be painful and the surgeon must be immediately informed. The pressure needs to be brought down medically or surgically.

Vaulting.

There may be a mismatch between the size of the lens and the space in the eye. This causes the lens to move forward and called anterior vaulting. This may also result in increase intraocular pressure as mentioned above.

So far, according to the company out of the 300,000 eyes with Visian ICL, there has been less than 1% of issue post procedure. The problems and risks associated with Visian ICL should be thoroughly discussed by our doctors before the procedure is agreed upon and performed on a patient.

Visian ICL is a great option for people with high powers or people who cannot wear soft lenses. We hope this information on Risks and Problems Associated with Visian ICL will prove helpful in your research.
