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.

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.

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.

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.
