Does Cataract Surgery Give You 20 20 Vision

So Why Do Some People Still Require Glasses After Cataract Surgery While Others Do Not

Can Cataract surgery give 20/20 vision? | Shekar Eye Hospital

There are many factors that determine if you will continue to wear full time glasses, part time glasses such as reading glasses, or none at all. These factors include the overall health of the eye, the amount of astigmatism, your current eyeglass prescription, and your visual needs.

Patients who have cataract surgery with a monofocal IOL may need glasses for some or all distances. Monofocal IOLs have been used for several decades and are set to provide your best uncorrected vision at one focal point. Many people who choose a monofocal IOL have it set it for distance vision and use reading glasses for near activities. On the other hand, a person whose IOLs are set to correct near vision would need glasses to see distant objects clearly.

Monofocal IOLs can also be set for monovision, which is distance vision in one eye and near vision in the other eye. If you are considering monovision, your ophthalmologist may suggest trying this technique with contact lenses first to see how well you can adapt. If you require crisp, detailed vision, monovision may not be the best approach for you.

Astigmatism is an imperfection in the curvature of your cornea. Astigmatism correcting IOLs can also be used to help decrease the dependence upon glasses. These IOLs are monofocal IOLs that correct astigmatism so you can see without glasses at one distance. You may still rely on glasses for some activities.

Vision After Cataract Surgery 20/20

But, all in all, my day of surgery was totally uneventful. I took my prescribed eye drops to prevent infection and reduce swelling, and hoped for the best.

I woke up on the first day after surgery and could not wait to remove my eye shield. My vision was a little more blurry than the day before, and I tried to explain this as overnight corneal swelling resulting from hypoxia to the eye. Different factors can cause this, including stagnant tears that aren’t blinked away during the night. Regardless of the cause, this kind of swelling can cause a greater myopic shift.

My near vision was still pretty good. I kept taking my eye drops. And by afternoon on the first postoperative day, the view through my right eye was like nothing I had ever recalled seeing before: clear and colorful in ways that even my best eyesight in younger years could not duplicate.

Outcomes on that first day postop were:

  • Visual acuity, 20/25

  • Internal eye pressure of 19 mmHg

  • Minimal internal inflammation

My vision was at least 20/25 before I had undergone cataract surgery. But this new 20/25 vision was not only different, but amazing.

I equated my new vision to the day I had purchased my first high-definition television . It was like looking at the world on an HDTV with my right eye and an old analog television with my left eye.

And, to this day, my “monocular 3-D” vision has continued.

Is Blurry Vision Normal After Cataract Surgery

Immediately following cataract surgery, it is, in fact, normal to have blurry vision. Many patients are back to their regular activities the day after cataract surgery. This applies to most activities except for driving. Driving isnt allowed until your cataract surgeon has okayed it.

During early recovery, patients will be able to see, but not in clear, but rather, soft vision. Within 48 hours, many cataracts patients see significant improvement in their vision.

It is possible that your vision could take one to two weeks to adjust and settle. The eye must adapt to the new intraocular lens that has replaced the lens. Every patient is different!

Types Of Cataract Surgery

Can Laser Eye Surgery Cause Cataracts? in 2020

Currently, there are two main types of cataract surgeries available. The first technique, phacoemulsification cataract surgery, is used throughout the United States and in most developed countries. It is the most common type of cataract surgery and only requires small incisions in the eye.

Phaco cataract surgery is performed by hand and involves opening up the eye to gain access to the cataract. Ultrasonic energy is then used to break up the cataract, which is then removed in pieces through gentle suction. Once the cataract is removed, a foldable intraocular lens is implanted into the eye directly behind the pupil.

The second type of cataract surgery available is laser-assisted cataract surgery, also referred to as LACS or laser cataract surgery. With this method, a computer-controlled laser is used to perform the operation rather than instruments handheld by a surgeon. The laser is programmed to make the initial incisions into the eye, access the cataract, and fragment the original cloudy lens.

LACS provides a high-speed and high-precision approach to traditional cataract surgery.

When Are Cataracts Bad Enough To Require Surgery

Reviewed by Vance Thompson, MD

When is the right time to have cataract surgery? If you are noticing vision problems and have been told you have cataracts, its likely your cataracts are bad enough to require surgery.

In some cases, people experience bothersome vision problems such as glare and halos at night even before their eye doctor notices significant clouding of the lenses in their eyes during a dilated eye exam. This condition called dysfunctional lens syndrome often is reason enough for many people to consider cataract surgery, especially if they need better visual acuity for driving at night.

However, financial considerations and insurance requirements also are factors when considering the best time to have cataract surgery.

Some insurance companies consider cataract surgery to be medically necessary and a covered service only after the cataract has caused corrected visual acuity to be reduced below a specified level. Often, this criterion is 20/40 or worse .

Be sure to review the details of your insurance policy with your insurance agent or your eye doctors staff so you understand if your vision qualifies you for coverage of your cataract surgery as a medically necessary expense.

What Happens If Cataracts Are Left Untreated

Cataracts can lead to other serious health concerns, such as glaucoma and macular degeneration. These conditions are very difficult to treat once they have occurred so your best option is to catch them early on through regular eye exams with our doctors. Glaucoma is a disease that damages the optic nerve and can lead to permanent blindness. This occurs because the pressure inside of your eye builds up over time, causing irreparable damage to this crucial part of your central nervous system.

Macular degeneration is a chronic condition in which cells within the retina begin to die off one by one due to age or exposure to ultraviolet light, or an injury. As these cells are lost, vision becomes progressively worse since this disorder affects essential parts of our eyes responsible for proper sight function.

After Cataract Surgery: What You Need To Know

The clouding caused by cataracts can seriously affect a persons quality of life. Fortunately, cataract surgery can correct the problem. The surgeon removes the lens and replaces it with an artificial lens. It is a relatively quick procedure with a fast recovery time that restores a persons quality of life.

Vision Quality After Surgery

Some patients ask if they will have 20/20 vision after the procedure. Most patients can achieve 20/20 vision as long as they have no other conditions. Conditions that can affect the quality of vision after cataract surgery include:

Because cataract surgery involves replacing the human lens with an artificial lens, any other condition affecting the eye may result in compromised vision. With the help of glasses, many people can achieve the 20/20 vision that they want.

Even in cases where a patient may be nearsighted or farsighted, there are some artificial lenses called multifocal lenses that can be used. They work like a bifocal contact lens, but they are placed permanently in the eye. These lenses are most effective when there is no astigmatism. Those with astigmatism will have to have another surgery before the artificial lens can be implanted.

Common Cataract Surgery Complications

During Surgery

To implant the artificial lens, the doctor has to make an incision. Anesthetic drops are used to numb the eye. If you prefer to be unaware of the surgery, you can choose general anesthesia.

It’s True Doctors Make Bad Patients

It’s well known that doctors make awful patients. For one thing, I knew far too much about the delicate body part upon which I was about to have surgery. I also had seen too many videos at conferences that illustrated “things gone wrong” during surgeries.

No question about it. I was very nervous, even though I had total faith in my surgeon.

I lectured myself about the importance of being a “good” patient, and not one of those dreaded “doctor” patients. I told myself that I would leave the choice of techniques strictly up to Steve.

Even though I was full of brilliant ideas about variations in techniques that might help my surgeon achieve the very best results, I decided to resist the temptation to offer him any of my many valuable insights.

In preparing for my surgery, I had my first complete eye exam. Like most emmetropes, I had never needed glasses for my distance viewing I needed only a pair of over-the-counter reading glasses, which I continue to wear.

My choice of a monofocal intraocular lens vs. a “premium”multifocal IOL was simple. My biggest complaints with the cataract were glare and halos. Because most of the visual complaints of patients who have premium IOLs result from the optics, I didn’t want to take the chance of continuing to have glare and halos with a multifocal lens.

Indications For Cataract Surgery

Cataracts: Symptoms, Diagnosis, and Treatment

If cataracts are interfering with your ability to see clearly, surgery may be a good option for you.

Cataract surgery removes the lens of your eye, which has become cloudy due to cataracts. The cloudy lens is then replaced by a clear artificial lens, so you can see much more clearly again.

According to the National Eye Institute , most cataracts are a side effect of aging, and they are very common in older people. It is estimated that over 50 percent of all Americans have a cataract or have undergone cataract surgery by the age of 80.

The first step in treating cataracts is to try corrective techniques, such as new eyeglasses, contacts, reading in brighter lighting, wearing anti-glare sunglasses, or using magnifying lenses. If these methods do not provide enough improvement, surgery is your only option for achieving clearer vision.

Cataracts should be surgically removed if:

  • You dont find relief through other corrective measures.
  • Vision loss caused by your cataracts is interfering with your ability to complete everyday activities, such as driving and reading.
  • The cataract is preventing treatment of another vision problem, even if the cataract itself is not interfering with activities of daily life yet.

NEI explains that cataract surgery is one of the most common operations performed in the United States. It is also one of the safest and most effective surgeries performed. Following cataract surgery, approximately 90 percent of people experience improved vision.

Will An Iol Give Me 20/20 Vision

Prior to cataract surgery, your eye doctor will use an ultrasound test to take precise measurements of the size and shape of your eye. These measurements will help your eye doctor to determine the most appropriate type of IOL, as well as how to accurately position the IOL. An effective lens position will enable the possibility of achieving 20/20 vision.

Equally important, is the exact calculation of your refractive error. Your eye doctor will calculate a precise measurement of your optical prescription prior to your scheduled surgery, in order to ensure that the correct power is attributed to your IOL. An accurate calculation of your refractive error will help you to achieve the 20/20 vision you are anticipating.

However, even with precise measurements, the IOL can move slightly during surgery, causing its position to shift as well. Your eye doctor will reexamine your eyes the next day, to determine if your IOL has remained in its correct position. In a case where the IOL has moved, your eye doctor can easily reposition the lens.

While many people will obtain 20/20 vision from their IOL, 30 to 50 percent of people who choose a monofocal IOL will still require corrective lenses after surgery.

Schedule a consultation with an eye doctor near you to see if you qualify for surgery.

What Happens During Cataract Surgery

The cloudy lens inside your eye will be removed and replaced with a clear artificial lens during surgery. This device is called anintraocular lens, or IOL for short.

An IOL helps restore the clear vision you had before cataracts developed.

During any form of cataract removal, special precautions are taken to make sure you’re completely relaxed and pain-free. At worst, patients can experience a slight sensation of pressure, but this feeling isn’t painful.

A modern cataract surgery procedure will often follow these steps:

  • A small incision is made along the side of the cornea.

  • A high-frequency ultrasound device or laser is used to carefully break up the cloudy lens into small fragments.

  • The lens fragments are gently removed from the eye using suction.

  • After all fragments have been removed, the surgeon places the IOL behind the pupil and the colored part of the eye in the same spot your natural lens occupied.

  • The incision heals on its own without any stitches.

  • A protective shield is placed over the eye to keep it safe during the early stages of recovery.

  • If you need surgery in both eyes, your cataract surgeon will typically wait one to three weeks between procedures, to give the first eye a chance to heal.

    Eyeglasses Recommended By Cataract Surgeons

    Before you have cataract surgery, your ophthalmologist will discuss your options for glasses following surgery. There is no best option for post-surgery glasses, as everyones needs and requirements are different. Cataract surgeons recommend being patient and waiting for your eyes to fully heal before being fitted for a new pair of glasses.

    Virtually any brand of eyeglasses will work provided the prescription is correct. Most eye doctors recommend that you wait at least one month following cataract surgery before getting a new prescription. This is to ensure your vision has stabilized.

    Because most IOLs used in cataract surgery can only provide clear distance or clear near vision, you will need glasses to correct for whatever the lens doesnt provide. Usually, just one lens in your glasses needs to be updated for the eye that was operated on.

    As long as your frames fit the updated lens, you may not need to make a big change to your eyeglasses. The important thing that ophthalmologists stress is to select the IOL and subsequent glasses based on your personal lifestyle and vision priorities.
