Frequently asked questions on cataract surgery.

Frequently asked questions on cataract eye surgery.

Cloudy vision or cloudy lens may lead to laser-assisted cataract eye surgery. There is nothing wrong with wanting to know facts about something. If you’ve been diagnosed with cataracts and your doctor says you’ll need to undergo cataract eye surgery, it is good to start asking yourself some questions.

Human beings are wired to ask themselves some questions when they are about to engage in something. If you see symptoms like blurred vision and other vision problems, you may likely undergo manual cataract eye surgery or phacoemulsification cataract eye surgery. 

And there is one thing about cataract eye surgery. It only takes a few weeks to get back to your normal vision. It’s a day surgery, except there are serious complications. But if there are no serious complications, the cataract eye surgery recovery period is about a month. 

Therefore, this article will provide an accurate answer to questions that may be running through your mind about cataract eye surgery.

Cataracts forms to damage the natural lens. And once the natural lens is faulty, one may likely undergo lens replacement surgery. So, cataract eye surgery is about replacing a natural lens with an artificial one. 

What is an artificial lens? Artificial lenses are contact lenses that are made from silicone or plastic. So, if you are battling cataracts, you may likely experience an intraocular lens implant. The artificial intraocular lens is essential in cataract surgical procedures. 

Before we proceed, let me ask you a question. Are you planning to undergo cataract eye surgery? Does your doctor ask you to prepare for cataract eye surgery? If yes, then you will see the exact thing you need here. Explore the effectiveness of the sleep apnea machine in adjusting to individual breathing patterns during sleep by clicking here.

Furthermore, it is expedient to create a piece of background knowledge. Therefore, we will discuss the meaning of cataracts and what cataract eye surgery entails. Hence, dear reader, you have a role to play. Therefore, please pay attention and shun all interruptions.

What is a cataract?

A cataract is a common eye problem that occurs when there’s a challenge in the cloudy zone of the eye lens. Furthermore, cataract starts when the eye begins to gather clumps. And when the clusters are too much, the lens will be affected.

Clumps will stop the lens from sending or transferring clear images to the retina. And once that occurs, one will begin to see symptoms like the glare of light, trouble seeing at night, and astigmatism.

Also, one can begin to find it so hard to read. A cataract is one of the major eye problems in Australia and other parts of the world.

What is cataract eye surgery?

Cataract eye surgery is the safest way of solving cataracts. If you’re battling cataracts, the only perfect way to restore your sight is by undergoing cataract eye surgery. Thus, cataract eye surgery is a simple process that involves cutting, breaking, and removing damaged natural lenses.

So, the next step is replacing the faulty natural lens with an artificial one. A professional ophthalmologist always carries out cataract eye surgery. It is a simple process that only takes twenty to twenty-five minutes.

When can I treat cataracts?

There is no specific time to treat cataracts. But, once you notice you are battling some symptoms of cataracts, the next thing is to visit an eye doctor. So, the eye doctor will carry out some tests on you. And once the test shows you have a cataract, you should rise and act.

The moment you start feeling strange things in your eyes, like the inability to read, astigmatism, and other eye issues, please visit your eye doctor. And, of course, you must wait to hear from your doctor to know if you need cataract eye surgery.

How long will cataract surgery take?

Initially, cataract surgery should only take twenty to twenty-five minutes. And if the process is more than that, there are serious complications. Conversely, cataract surgery may take more than twenty minutes if complications like bleeding occur.

Also, the surgery time depends on your eye’s lens. If swelling occurs or there’s a problem in joining the flesh together, the process may take up to one hour. 

But if there is safe and free cataract surgery, you should leave the theatre room after twenty-five minutes. Please permit me to chip in something. Please ensure you get a competent surgeon.

Is cataract surgery painful?

Cataract surgery is not painful. The ophthalmologist will give you some sedatives. The work of the sedative is to calm your nerves and make you relax. And there’s a medicine you will take before the process. Of course, the process involves few or no stitches. But it is not painful. 

You will stay awake during the process. However, from what we gathered from people that have experienced cataract surgery, they all said it is not painful. Therefore, feel free to undergo this process.

Will you wear glasses after cataract surgery?

No one can say yes or no to this question. Do you know why? The instruction about using eyeglasses before cataract surgery depends on the outcome of the surgery. Some people are instructed to use eyeglasses after cataract surgery.

On the other hand, we have heard about people who are instructed to stay away from eyeglasses after the surgery. It depends on the outcome of the surgery. If the process takes a long time, your doctor might instruct you to use eyeglasses to prevent infections.

And if the surgery process is perfect, your doctor might instruct you not to use eyeglasses. Therefore, no one can say either yes or no to this question.

What are the dos and don’ts after cataract surgery?

Of course, there are dos and don’ts—one of the things you must avoid after cataract surgery is rubbing your eyes with your hands. Days after the surgery, you may feel like rubbing your eyes with your hand. And if you think that way, please don’t do it.

Also, if you love swimming, you need to abstain from swimming for at least two weeks after the surgery. If you want the healing process to be fast, you must suspend swimming for some time. 

Thus, it is essential always to visit your doctor’s office. He may want to instruct you to use eye drops, eye shields, or another protective shield to prevent infection.

Furthermore, it is essential to bear in mind that you must avoid placing your eyes on rays of light. Some people will be restricted from the screen. If you can’t do without putting your eyes on screens, there’s a tendency you will have to do the surgery again.

That is why we have twice seen people enter the theatre room for cataract surgery. That is why having a smooth relationship with your ophthalmologist is good.

Will I use eye drops after cataract surgery?

Some eye surgeons will prescribe an eye drop to you even after the surgery. We have seen someone instructed to use antibiotic eye drops even after the process. So, it depends on the state or condition of your eye. Eye drops are part of the treatment. Please expect it. 

If your eye is in good condition, your cataract surgeon might not ask you to use eye drops. A doctor said an eye drop is a protective shield. Therefore, it is your eye doctor’s discretion whether to use eye drops or not after the surgery.

On a final note

Dear reader, cataract surgery is a simple procedure. Therefore, with the above-listed answers, we believe you have a clue about what to do. Hence, the ball is in your court. Please play it as you like.

Finally, your thought regarding this topic counts. So, please share your opinion on this topic with me. And if you have more questions about cataract surgery, please bring them on.

A view on the pros and cons of LASIK

Since 1999, the FDA has authorized LASIK for vision correction. Today, around 600,000 LASIK operations are performed annually in the United States. The great majority of persons who have this operation get 20/20 vision, and the vast majority – more than 95% – express satisfaction with the outcomes.

Nonetheless, complications include as glare and halos are prevalent after LASIK. And, in rare occasions, individuals have lost eyesight, had long-term discomfort, or experienced other complications.

Morris Waxler, PhD, a former FDA official who was a member of the panel that authorized the operation, has alleged in recent years that the FDA overstated the hazards. He has requested that the agency withdraw LASIK from the market. The FDA answered that the data did not warrant a recall, but that it would continue to evaluate LASIK safety.

Is LASIK a safe procedure? Yes, according to Edward Manche, MD, an ophthalmology professor at Stanford University School of Medicine and division head of Cornea and Refractive Surgery. “It has been authorized by the FDA and its safety has been verified,” he adds. “While some individuals have had difficulties, the great majority of people fare exceedingly well.”


Laser-assisted in situ keratomileusis, or LASIK, is a kind of refractive surgery. The surgeon begins by cutting a tiny tissue flap from the front of the eye. The cornea is then reshaped using a laser to improve light focus on the retina at the rear of the eye. LASIK is a procedure that may be used to address visual abnormalities such as nearsightedness, farsightedness, and astigmatism.

Over the last two decades, physicians in the United States have done more than 19 million LASIK treatments. Although there have been few high-quality, long-term studies on the results, the evidence that exists indicates that the operation is safe and successful.

LASIK is an excellent operation,” says Jennifer Ling, MD, a clinical assistant professor in the University of Iowa Hospitals & Clinics’ Cornea and External Eye Disease Clinic. “It has been able to significantly improve the lives of a large number of individuals by providing them with good vision and liberating them from their glasses or contact lenses.”

Over 90% of patients who get LASIK obtain 20/20 vision, which means they can see well from a distance of 20 feet what a person with normal vision should be able to see without glasses or contact lenses. Over 99 percent of individuals get 20/40 or greater vision, which is sufficient for passing the driver’s license test.

Daniel Sklar, 56, of Smyrna, GA, had the operation in 1999 to treat severe nearsightedness and astigmatism. Following that, he moved from wearing heavy spectacles to having eyesight that was better than 20/20. “It has resulted in a significant increase in my quality of life,” he adds. “To be able to wake up, wash, and see, as well as swim or snorkel without prescription goggles.”

LASIK has been even more successful over the years due to advancements in the treatment. “The outcomes have consistently improved over time as more modern technology has become available,” says Joshua Frenkel, MD, an associate surgeon at Wang Vision Institute in Nashville. The femtosecond laser, launched in 2001, cuts a flap in the cornea using light pulses. The method has been transformed by femtosecond lasers, which provide higher safety and accuracy than a blade.

Other technological advancements enable the production of a personalised map of the cornea, resulting in more accurate vision correction and improved results. “The goal is to eliminate higher-order aberrations, which may result in glare, nighttime halos, and other effects,” Frenkel explains.

Cons of LASIK

The most common adverse effects of LASIK are moderate — including dry eye, burning, and itching, which occur in 20% to 40% of patients. These symptoms often peak about three months following surgery and subside between six to twelve months — although this is not always the case.

Holly Strawbridge, a 68-year-old freelance writer from in Fort Lauderdale, FL, has suffered dry, red eyes since undergoing LASIK eye surgery around 17 years ago. “It’s been an issue,” she admits. “It seems as if I’ve been pulling a lot of all-nighters.” She claims that even if she had been aware of the dryness beforehand, she would have proceeded with the procedure. “To be honest, when compared to the inability to see, dry eye takes a second place.”

Additionally, glare and halos surrounding lights at night, as well as trouble with contrast, are prevalent. Around 20% of those who get LASIK have these complications. They may also improve over six to twelve months, but only a tiny percentage of individuals experience them long-term, Manche explains. If you have one of these problems, you may either return to glasses or contacts or undergo revision surgery.

Additionally, there is a potential that LASIK may not entirely restore your vision, particularly if you were very nearsighted or farsighted to begin with. If this occurs, you will need glasses or contacts in order to see well. “If you are not completely fixed… you may return in three to six months for more surgery,” Manche explains. “The great majority of patients get 20/20 vision in such instances.”

It is very unusual for a vision chart to lose lines of vision. “Even with glasses or contact lenses, eyesight cannot be restored to its pre-LASIK state,” Ling explains. “The likelihood of it occurring is very remote. This is often the result of infection, scarring, or inadequate recovery.”

Even though your eyesight is 20/20 immediately after LASIK, it may not remain thus. Vision may regress. And as you age and the structure of your eye naturally changes, you’re likely to require reading glasses. “As I’ve grown older, the impact of LASIK has waned,” Strawbridge explains. “However, I have had at least ten years of flawless eyesight.”

The majority of LASIK-related complications are transient and provide only little inconvenience, but in some individuals, they are severe enough to be life-changing. John Christian, 44, had the operation in May 2015. He visited a respected hospital and had tests to see if he was a suitable candidate. However, he experienced dry eye shortly thereafter. Treatments such as tear plugs and prescription eyedrops were ineffective, and the dryness became worse.

A patient’s account after LASIK

“By 12 to 15 months after the treatment, the dry eye feeling had morphed into throbbing agony,” a patient reports. “I had the distinct impression that someone was poking knives into my eye and all the way through my mind.” Only after he fell sleeping did the discomfort subside.

John consulted a specialist two years after his treatment, who diagnosed him with ocular neuralgia — discomfort caused by damaged nerves in the cornea. It’s an uncommon but devastating adverse effect that has been connected in a tiny number of instances to LASIK treatment.

He is now receiving a battery of therapies, including eye drops manufactured from his own blood, steroid drops, and painkillers. “My daily pain level decreased from 9 to 2 on a good day to 6 to 7 on a poor day.”

Despite his perfect eyesight, he responds, “Never.”

“Certainly, my attitude on risk-reward has shifted.”

Hearing experiences like John’s from individuals who have been harmed by the procedure motivated Waxler to advocate for more explicit warnings about the hazards of LASIK, which he has been doing for over 12 years. Jessica Starr, a Detroit meteorologist who died by suicide in December 2018 at the age of 35, after discussing her experience with LASIK problems with her audience, was one of the most prominent of these examples. (It is unclear if her suicide was caused directly by her operation.)

Another disadvantage of LASIK is its high cost — around $2,200 per eye. “With few exceptions, insurance does not cover it,” Manche explains. You may pay for the procedure using a flexible spending account (FSA) or a health savings account (HSA). Get more detail about LASIK eye surgery cost on

Obtaining the Best Possible Outcome

LASIK is not suitable for everyone. “The most critical thing is to ensure that you are a qualified applicant,” Manche explains. “Some persons may have issues not as a result of the operation, but as a result of their ineligibility.”

“Every individual should have a comprehensive one-on-one examination and consultation with their doctor to ensure that LASIK is a good fit,” Ling advises. Prior to your operation, the doctor should do a complete eye exam, assessing the shape of your cornea and searching for abnormalities such as dryness or other undiscovered eye disorders.

Certain individuals are not candidates for LASIK. If your cornea is excessively thin or uneven, you may need to avoid this surgery; if you have cataracts or glaucoma; if you have uncontrolled diabetes or an inflammatory condition such as Sjögren’s syndrome or rheumatoid arthritis; if you are pregnant; or if you are under the age of 18

Finding an experienced physician is one of the keys to a good result. You may seek recommendations from friends and family members who have had LASIK, or you can contact the American Academy of Ophthalmology. Manche recommends that you seek a second opinion. “That way, you’ll feel more secure if two physicians agree.”

The doctor should take their time and thoroughly explain the operation, including any potential dangers. “You do not want a physician who promises, ‘This is 100% sure to work.’ ‘You’re going to adore it,’ Ling declares. “That is a really large red flag.” Choosing a university medical facility over a private practice, she argues, may be a safer decision.

Additionally, you must enter LASIK with reasonable expectations. Around 90% of patients will attain 20/20 uncorrected vision or better, while 10% will not, and up to 40% will have negative effects. “Generally speaking, the higher the prescription, the greater the danger of adverse effects,” Ling explains.

“I feel that a large number of individuals assume that LASIK is completely assured. It is a very effective operation for the great majority of patients. However, nothing in medicine is 100 percent certain,” she explains. “If someone enters LASIK believing they will be assured 20/20 vision with no dangers, they have been misinformed and may be disappointed.”

The following are the most common eye conditions that may be addressed by LASIK laser surgery:

Nearsightedness is referred to as myopia.

Myopia, or nearsightedness, is caused by an abnormally long eye shape and/or an abnormally steep cornea. As a consequence, light entering your eyes does not concentrate on the retina as it should, but on pictures in front of the retina. Nearsightedness causes distant items to look fuzzy, while close ones appear distinct.

Hyperopia, or hyperopia, is a condition in which one is farsighted.

If you have hyperopia, or farsightedness, it is due to either an abnormally small eye shape or an abnormally flat cornea. Farsightedness occurs when light entering the eye focuses on pictures beyond the retina. Farsightedness causes close items to look fuzzy, while far ones appear clear. In rare circumstances, hyperopia may result in blurriness both at a distance and up close.


Astigmatism occurs when the cornea of your eye is not spherical or basketball-shaped, as it is in a normal eye. Instead, your cornea is often shaped more like a football. Astigmatism causes the items you are observing to be distorted or hazy because they are not focused into a single picture. Astigmatism may occur alone or in conjunction with near- or farsightedness.


If you have presbyopia, you lack the capacity to concentrate on near things. This is a natural process of aging and often becomes noticeable in adults in their forties. Presbyopia occurs when the internal lens of the eye loses its capacity to focus on close-up things. While laser vision correction significantly improves distant vision, the majority of individuals will continue to need glasses for close-up tasks, especially as they age. 

Presbyopia may be treated using reading glasses or multifocal lenses. For appropriate applicants, surgical treatments for presbyopia such as monovision LASIK are available. Consult one of our surgeons about repairing presbyopia during your eye checkup.

Cornea Remodeling

If you use glasses or contacts, they will bend the light to suit your prescription. The LASIK Vision Institute’s experts perform a laser vision correction surgery in which they rebuild the cornea to appropriately refract light for corrected vision. The laser shoots cold, invisible ultraviolet light to precisely reshape the cornea without causing damage to surrounding eye tissue. After that, the cornea correctly refracts light, allowing you to see normally. These are the most modern FDA-approved lasers available, ensuring the most accurate eye correction possible.

7 Tips for a better LASIK outcome

Regardless of how long LASIK has been around, doctors can always find methods to improve treatment quicker, safer, or better. From numerous experienced doctors, here are ten pearls to help you optimize your LASIK experience from preop through postop:

Anti-inflammatory medicine used before to the LASIK surgery. 

“For the three days before the LASIK eye surgery, I utilize a fourth-generation fluoroquinolone and steroid q.i.d.,” explains Greensboro, N.C., surgeon Karl Stonecipher. “I believe it aids you by removing any blepharitis or meibomitis from the lid edges. Additionally, it cleanses the tear film, resulting in a much-improved picture when patients come in for preoperative wavefront analysis. This results in a decrease in the overall enhancement rate, since the data that is input is the data that is output.”

Dr. Stonecipher begins Restasis one to two weeks prior to the LASIK surgery and maintains it for one to two months or longer, depending on the patient’s symptoms.

Estimation of the depth of ablation using LADARVision. 

With Alcon’s LADARVision technology, the surgeon really understands how much tissue the laser will remove on the day of operation after the patient is dilated and his wavefront photographed, which is then entered into the surgical planning software. Regrettably, if the surgeon predicts that it will remove too much, he or she may be forced to inform the patient on the day of the LASIK surgery that they are not eligible for LASIK. 

Michael Taravella, MD, Clearvision Laser Centers’ national medical director, claims he’s devised a method for estimating the depth prior to the day of operation. “We take the overall root mean square of the patient’s higher-order aberrations and put it into a regression model that we devised [he will describe the formula in a poster presentation at the 2007 American Society of Cataract and Refractive Surgery conference].” “This always provides us with an accurate estimate of the quantity of tissue that the laser will ablate, to the nearest 5 m.” Checkout more information about LADARVision on

Psychological preparedness. 

According to Elizabeth Davis, MD, of Minneapolis, in order to get patients’ cooperation during the LASIK surgery, it is beneficial to prepare them for what is to come. “I tell them I’m going to insert an eyelid opener and it’s going to feel a little stretched, but to avoid squeezing their eyes,” she explains. “Second, I inform them that there will be times when their eyesight may weaken or perhaps go completely black, but that this is a positive thing. I need it as proof of a LASIK surgical procedure. Then I inform them that they will have a brief sensation of pressure or burning for around 20 seconds. If you do not inform them of these facts, they will either clench when the speculum is inserted, or they may panic and exclaim, ‘My eyesight is cloudy! Now everything is black!’ or ‘I feel like I’m on fire, but my buddies assured me it wasn’t!'”

Take care to avoid transcribing mistakes. 

Dr. Taravella states that he always instructs his residents and fellows to “work backward” while transitioning from plus to minus cylinder notation in order to minimize transcribing mistakes during ablation planning. “First, you rotate the cylinder 90 degrees,” he says. “Then reverse the cylinder’s indication. Finally, you combine the sphere and cylinder to form the sphere.” As an example, suppose the refraction factor is -1 +2 x 85. To begin, the surgeon adds 90 degrees to the axis, bringing it to 175 degrees. He then alters the sign of the cylinder to negative. The sphere becomes +1 when the sphere and cylinder are joined. Thus, the refraction in the negative cylinder becomes +1 -2 x 175.

“If you’re doing custom transcription, you won’t encounter an error,” Dr. Taravella explains, “as long as you have the correct floppy disk [or whatever medium the patient file is on] for the correct patient.”

Customize monovision. 

Andrew Caster, a physician in Los Angeles, offers a novel approach to monovision. “Some surgeons immediately prescribe modest monovision to all patients, assuming that the patient would favor the non-dominant eye for near,” he notes. “What I highly advocate is properly assessing each presbyopic patient for monovision using a trial frame, rather than immediately prescribing or refusing monovision.” I begin by correcting the distance in both eyes, then attempting a modest amount of monovision in the left eye and then the right, allowing the patients to choose which direction they prefer the monovision. If they despise it, we will not proceed. 

If they agree, I’ll assess whether they prefer the left or right eye for close vision and then experiment with various intensities of monovision. They put on trial frames and walk around the office for these tests, then return to tell me which frames they prefer. We want children to gaze both far and close. It’s quite subjective—some individuals prefer their non-dominant eye to be used for distance.

“I’ve discovered that this system works extremely well. If the patient has exhausted all possibilities, he will feel as though he has exhausted all possibilities and has a firm grasp on a potentially confusing subject.” Dr. Caster is in charge of testing. “Time invested in the chair in advance will save countless hours later on attempting to assist dissatisfied patients,” he asserts. “It is uncommon for us to have a dissatisfied patient.”

Proper placement. 

“Ensure that the patient’s chin and brow are level,” Dr. Taravella advises. “The chin should not be elevated or lowered excessively. This becomes critical when working with trackers and iris registration, since you do not want shadows to cause these devices to malfunction. In rare situations, a deep-set eye may also confound both a tracker and registration.”

Microkeratome management. 

When Dr. Davis is ready to cut the flap, she presses the foot pedal for a brief while, advancing the blade, and then releases it before the blade contacts the cornea. “What this often results in is the patient jumping from the first buzz,” she explains. “I can then continue with the cut without having to worry about his leaping while I’m engaging the cornea.” After creating the flap, she decreases suction on the reverse pass to assist in reducing the frictional forces on the flap, hence eliminating epithelial flaws.
