Does Cataract Surgery Improve Vision

Is Cataract Surgery With Vision

Laser Precision Restores Vision after Cataracts

Cataract surgery is a very safe procedure, with nearly 98 percent being performed without serious complications. In fact, a recent study of more than 200,000 Medicare beneficiaries who underwent cataract surgery between 1994 and 2006 found that 99.5 percent of patients had no severe postoperative complications. Advances in surgical tools and techniques are helping to further reduce the already rare risk of serious complications from cataract surgery. All cataract surgeries involve the implantation of an artificial lens called an intraocular lens or IOL. Therefore, cataract surgery with vision-correcting intraocular lens technology carries a similarly low-risk profile of all cataract surgery. That said, all surgery comes with a degree of risk even a very small one and you and your eye surgeon should discuss your procedure in detail so you can make the best decision for you and your vision.

While complications after cataract surgery are uncommon, the good news is that most can be treated successfully. Your personal medical history and eye health may contribute significantly to your risk of complications from cataract surgery. Some of the risks of cataract surgery include:

  • Inflammation and/or infection

Benefits Of Cataract Surgery

Cataract surgery is a popular and reliable solution for obtaining clearer vision. It is a short and simple procedure where the natural lens is replaced by an artificial one. A comprehensive eye exam can help determine if you are a candidate for lens replacement surgery.

Benefits of cataract surgery can include:

  • Improved vision:Cataract surgery successfully restores vision for the majority of people who undergo the procedure. Objects appear more crisp and clear, and colours appear brighter. As the eyes heal and adjust to their new lenses, vision continues to improve.
  • Improved eye health: Cataracts can cause eye inflammation, increase intraocular pressure, and make it more difficult for your optometrist to treat and prevent other eye problems.
  • Improved safety: Better vision helps decrease the risk of falling, car accidents and other safety-related incidents.
  • Improved quality of life: Blurry vision makes it difficult to enjoy our daily lives, and reduces our independence. Improved eyesight can have a positive effect on mood and mental health.

What Happens During Cataract Removal

Cataract surgery is a pretty straightforward procedure that can be completed in a matter of minutes. It’s done on an outpatient basis, so you don’t have to spend the night in the hospital. The first step involves numbing the eyes using special eye drops, so patients feel comfortable. We then implement advanced laser technology to make a small incision, and break apart and remove the cataract.

Once the cataract is removed, our vision professionals replace it with a cutting-edge intraocular lens. Patients are sent home and given instructions for protecting the treatment area and making sure the outcomes are both long-lasting and successful.

What Is Refractive Cataract Surgery

Refractive cataract surgery is a procedure that involves removing the natural lens of the eye to correct cataracts and vision issues, like nearsightedness, farsightedness, or astigmatism. An intraocular lens is then implanted to replace the natural lens and provide clear sight without glasses or contacts. Many people who undergo this surgery are thrilled to reduce their need for corrective lenses.

Patients should understand that while refractive cataract surgery does improve vision, it may not cure refractive errors completely or prevent them from happening in the future.

What Kind Of Reading Glasses Do I Need After Cataract Surgery

Cataract Surgery: How it Can Improve Your Vision and Your Life

In order to determine which type of glasses you need after cataract surgery, you should go through a series of tests. If the surgeon has prescribed reading glasses for you, it is important to find out if they are bifocal or progressive lenses. You will need to know the power and the distance for which you need your glasses for.

Bifocal lenses are necessary for those who have difficulty focusing on near and far objects. They are incorporated in the same frame so the wearer can adjust between reading text close up or seeing objects at a distance. Progressive lenses are more expensive but offer better vision for more complex tasks.

Bifocal lenses have the property of providing a clear view of the near and far distances while multifocal lenses provide clearer vision at all distances. They are made up of two optical components, one near to see close objects, and one far to see objects in the distance. Multifocal lenses have only one optical component that provides clear vision at all distances.

How Are Patients Selected For Cataract Surgery

Visual acuity is the ability to resolve fine detail and is usually measured using letters of diminishing size such as a Snellen chart. However there is poor correlation between visual acuity and visual function when calculated using more holistic tests . For example glare and decreased contrast sensitivity often affect cataract patients more than expected, especially in extremes of illumination . There are tests to measure this, but they are rarely used in practice because of practicality and time constraints .

Although visual acuity is used as an objective measure when considering cataract surgery, it is standard practice to select patients on their symptoms of visual function and quality of life rather than purely on their visual acuity. Patients have widely differing visual demands and it is vital to take these into account when considering surgery.

It is also important to assess general co-morbidity which may hinder the improvement of function following cataract surgery and this should be taken into account when the decision to operate is taken, especially as some factors, such as deafness, poor mobility, and decreased cognition can increase the risk of peri-operative complications .

How Much Vision Will I Regain After Cataract Surgery

If you have cataracts, you know that living with them can make it harder to accomplish even the simplest of activities. The only way to effectively treat cataracts is by having cataract surgery.

Can A Cataract Grow Back In The Synthetic Lens

Cataracts dont grow back in artificial lenses, However, something called a secondary cataract can develop roughly 4-6 months following the surgery.

This isnt an actual cataract, but rather a problem with the capsule, which is a cellophane-like outer lining that holds both the natural and replacement lenses.

During cataract surgery, the natural lens in the eye is removed, but great care is taken to keep the capsule in place to hold the replacement artificial lens.

Sometimes, months after the surgery, the posterior capsule becomes cloudy just as the natural lens did to form the cataract.

This results in some loss of vision and your ophthalmologist needs to perform a posterior capsulotomy using a special laser tool to reduce the obstruction. This is a quick office procedure that usually results in pronounced vision improvement.

What Is Vision Like Before Cataract Surgery

How soon will my vision improve?

Cataracts cause more than blurry vision. There is actually a wide variety of symptoms caused by cataracts:

  • Glare and / or difficulty driving at night
  • Poor ability to see contrast, such as in a dark or dimly lit environment
  • Change in perception of colors
  • Change in the glasses prescription of the eye

Of course, the most common symptom that people have is blurry vision. Cataracts are a clouding of the natural lens inside the eye. As this lens gets cloudy, light has a harder time passing through. Because we use light to see things, this cloudiness makes things more blurry. Details become much harder to make out.

This cloudiness also impairs are ability to see things in low light environments. Cataracts block light and individuals with cataracts often find they need to shine more light on objects to see them.

But blurry vision isnt the only symptom people notice. There are types of cataracts that cause a very high amount of scatter of light especially when lights are shining in the eye. This causes lots of difficulty with glare and this makes it more difficult to see at night. Subsequently, driving at night is often the first activity which is given up once cataracts start to develop.

Live Longer With Cataract Surgery

A recent study published by JAMA Ophthalmology* examined 74,044 women with an average age of 71, who had cataracts. 41,735 of those women underwent cataract surgery. The results showed that cataract surgery reduced the risk of dying early by 60% for all causes of death. The study went even further finding a 37% 69% lower chance of dying from an accident, cancer or lung and heart disease. Dr. Chu was on KARE 11 discussing cataract surgery and this study. You can view the KARE 11 video below.

Is Laser Eye Surgery Safe If You Have Had Cataract Surgery

Many patients can undergo laser surgery safely after refractive cataract surgery as long as they are healthy enough to do so and choose a qualified surgeon to perform the procedure. Patients at Young H. Choi, M.D. Eye Surgery Center must undergo a comprehensive evaluation, including a discussion about any issues or medical conditions that could affect surgical outcomes.

Patients should also realize that refractive cataract surgery does not cure refractive errors completely and they may still need corrective lenses after the process is over. Our team can let you know what to expect if you are interested in laser eye surgery after cataract surgery.

Since nothing is 100% guaranteed when it comes to health and body functionality, there is a chance that some patients may experience complications after refractive cataract surgery. In these cases, laser vision correction may not be recommended.

Unexpected Benefits Of Cataract Surgery

Each of your eyes has a lens, which is a clear membrane that allows light into your eye. When you have cataracts, one or both of the lenses in your eyes become cloudy. This cloudiness can interfere with your vision, making it harder for you to watch television, read, drive, and do other activities.

Cataracts are a common aging-related health condition. More than half of all Americans develop cataracts by the age of 80.

Cataract surgery is the only treatment for eliminating cataracts. Its a common procedure thats very effective and safe when performed by an experienced eye surgeon like Dr. David ODay at Charleston Cornea & Refractive Surgery. During cataract surgery, Dr. Day removes the cloudy lens in your eye and replaces it with an artificial lens.

After cataract surgery, you can see more clearly. But cataract surgery delivers some other unexpected benefits, too. Heres a look at what else you can look forward to after having cataract surgery.

How Does Cataract Surgery Help To Improve Vision

What Is Cataract Surgery With Vision

Cataract surgery removes the clouded natural lens and replaces it with an artificial plastic lens. Todays lens technology enables cataract patients to not only replace their clouded lens with a clear plastic lens, but also correct other vision issues such as nearsightedness, farsightedness, and astigmatism. Working with your ophthalmologist, you can customize the procedure to your personal vision needs using todays advanced intraocular lens technologies. The process of cataract surgery is essentially the same for everyone:

There are a few lens options for lens replacement surgery. Which intraocular lens is right for you depends on your lifestyle as well as your vision needs. Your ophthalmologist should discuss your options and help you choose between:

Standard or Monofocal lenses:

These lenses correct for one range of focus vision only either near or distance, but not both. The patient will continue to rely on corrective glasses or contacts for the uncorrected range of vision as well as astigmatism.

Multifocal or accommodative intraocular lenses:

Designed to give presbyopia and cataract patients clear vision for both near and far objects, so you are less dependent on glasses.

Toric intraocular lenses:

A monofocal lens that also treats astigmatism. Toric lenses also help correct distance vision, but you will likely require glasses for reading.

How Does Laser Eye Surgery Work

Laser eye surgery corrects refractive errors by making minor adjustments to the cornea. This changes how light is focused onto the retina, resulting in better vision. The procedure has a high success rate, and Young H. Choi, M.D. Eye Surgery Center uses advanced laser technology to provide the most accurate vision correction results possible. Benefits of surgery in Birmingham, AL include:

  • Short recovery times

  • Lower risk of complications, like infections, compared to other methods of vision correction

  • Long-term freedom from glasses and contacts

What Is Cataract Surgery Like

New Technology Improves Cataract Surgery Results

Cataract surgery is a common, safe procedure, Dr. Wang says. It is performed in an outpatient setting with patients returning home the same day. Patients have surgery done in one eye and typically return for the second eye after a few weeks.

The whole experience of cataract surgery only takes a few hours, but the surgery itself only takes 15 to 20 minutes on an average case, Dr. Wang says.

First, your eye is numbed with a local anesthetic . You remain awake during the procedure, but you are given light sedation through an IV to make you relaxed and comfortable, Dr. Wang explains.

The surgery is overall fairly painless, she says. Most patients will complain of a little itching or irritation overnight during the first night. And their vision typically improves by the next day.

Patients will go home with a shield over their eye for the first day and then wear it only at night for one week.

We recommend patients just take it easy and only do light activityno heavy lifting or bending, says Dr. Wang. Other than that, you can usually go back to work within a day or two.

Additionally, patients should expect to take several eye drops for about a month after surgery to help the eye heal and to prevent infection.

Is There Anything I Can Do To Prevent Cataracts

While nothing can be done to prevent cataracts, you may be able to slow their progression by protecting your eyes from sunlight and managing underlying conditions like diabetes. Cataracts cannot be reversed, so when they interfere with everyday activities, surgery will be required to restore your vision.

How To Improve Near Vision After Cataract Surgery

Near vision after cataract surgery can be improved with prescription glasses or choosing bifocal or multifocal intraocular lens for implantation during cataract surgery.

It is a well-known fact that your near vision becomes poor after cataract surgery. This almost always happens when a monofocal intraocular lens has been implanted during cataract surgery and, in some cases, where bifocal or multifocal IOL has been implanted. This problem is usually easy to manage and can be rehabilitated by using corrective glasses or contact lenses.

Monofocal IOLs are meant for correcting distance vision. The near vision remains uncorrected and requires glasses after cataract surgery. Bifocal and multifocal IOLs are designed to provide both near and distance vision.

The reason glasses may still be required after implantation of bifocal or multifocal IOL is that the final visual outcome is not 100% predictable with the current technology for IOL power calculation and surgical techniques.

Hence, the postoperative residual refractive error may still be an issue. For example, the postoperative residual refractive error after implantation of a bifocal IOL may be within ±0.5 D of the intended refraction.

As mentioned above, intraocular lens may be of the following types:

1. Monofocal Intraocular Lens

A monofocal intraocular lens is an artificial lens that corrects only distance vision. After cataract surgery, the person needs glasses for near vision.

2. Bifocal Intraocular Lens

How Long Does It Take To Adjust To Glasses After Cataract Surgery

Adjusting to glasses is gradual process that takes place over the first weeks and months.

The first step of adjusting to glasses after cataract surgery is getting used to the visual acuity you acquire after surgery and more so after starting to use corrective glasses for near vision. This may take a few weeks.

After this period, you will notice that your distance vision is clearer than before, but your near vision wont be as good as it used to be. This means that reading or computer work will require more effort than before.

Wearers of glasses or contact lens users should be aware that they may need to wear them for a few weeks following surgery as their eyes require time to readjust and for their prescription to change.
