5 Side Effects of Laser Eye Surgery and How to Prevent Them

Laser eye surgery is revolutionary and life-changing for patients. Like all surgical procedures, there are risks involved that can be minimized or eliminated. The most important way to reduce risk is to seek out a good surgeon that you can trust with a known track record. The operating surgeon or one who can perform the surgery personally must examine you at consultation. Additionally, the functional Centre must have all the necessary diagnostic technology and care pathways and trained staff to ensure that all testing performed is complete and high standard.

You MUST educate yourself well, and here are some of the specific risks reported and how they can be minimized or eliminated.

1. Dry eye

Dry eye following laser eye surgery is typically a temporary phenomenon but can become a long-term problem if patients are not appropriately evaluated before surgery. Learn more about Laser Eye Surgery at https://www.personaleyes.com.au/costs/lasiklaser-eye-surgery-cost

Dry eye following LASIK and PRK occurs because the superficial nerve endings on the cornea’s surface need to regenerate and heal. The cornea is a little numb and does not have the sensation required to trigger tear production. Additionally, nerve endings produce chemical messengers (cytokines), which act as growth factors coordinating interaction between surface cells. Nerves regenerate in 6 to 12 weeks, and during this time, the eyes are prone to getting dry.

Long-term dryness can occur if an underlying problem has not been diagnosed and treated adequately before surgery.

Symptoms: Grittiness, burning, fluctuating vision, pain

Prevention

Make sure the operating center performs dry eye tests, including

a) Schirmer’s test for tear production and

b) Tear Break-Up Time (TBUT).

Make sure your operating surgeon is also experienced and knowledgeable about dry eye.

1. Ask your surgeon if you have Meibomian Gland Disease. Meibomian glands are located in the eyelids and produce vital oils, which helps to prevent tears from evaporating too quickly.

2. In advance of your laser eye surgery, consider taking re-esterified Omega 3 supplements to improve your Meibomian gland function.

3. Take preservative-free eye drops frequently after your procedure

4. Take breaks from computer monitors every 20 mins, close your eyes for 20 seconds and look out of the window for 20 seconds – then get back to work.

2. Halos and Glare

For some days to a few weeks following LASIK eye surgery (both Lasik and surface ablation), ALL patients experience halos. This is because fluid within the recently treated cornea causes light to scatter. 

Once the fluid clears, the halos disappear. Some patients, however, develop permanent halos following surgery and find their symptoms are worse at night (left-hand image). This problem is caused by induced aberrations from lasers that have delivered small diameter zones of correction or older forms of treatments not Aspheric in profile. 

The good news is this problem does not occur very often as long as patients are selected correctly and the correct treatment customized for each eye is delivered correctly. This problem can also happen if the treatment has not been centered perfectly.

Prevention 

1. Ensure your pupil size is measured in dim/dark light

2. Ensure your surgeon is experienced in Laser eye surgery and understands the significance of high order aberrations.

3. Ask your surgeon if you will be receiving an ASPHERIC treatment profile on your cornea. Good cameras and spectacles have “Aspheric” lenses to provide good quality vision.

4. Ensure the treating center has laser eye surgery technology that is up to date and well maintained.

3. Infection

Like all surgical procedures, there is a risk of infection. Fortunately, the risk of disease in laser eye surgery is minimal. The risk of infection from highest to lowest is LASEK, PRK, blade -LASIK, and IntraLASIK with a femtosecond Laser carrying the lowest risk of all. The overall risk of infection after IntraLASIK in excellent eye centers is 1 in 10,000 cases.

Prevention 

1. Go to a reputable center that has an excellent Care Quality Commission (CQC) rating

2. Ask about the environment in which laser eye surgery is being carried out. Is the air HEPA filtered, and the exchange rate per hour? 10 per hour is the minimum required; many use 15 per hour.

3. Ask what antibiotics are used in preoperative preparation and during surgery. Ideally, a 4th generation fluoroquinolone such as Moxifloxacin or Gatifloxacin. These antibiotics are powerful and eliminate a wide variety of bacteria.

4. Ectasia

This is a condition where the cornea is more elastic than usual and can become unstable following laser eye surgery; the cornea becomes “ecstatic,” in other words, it bulges and thins over time. This results in a change in vision with the requirement to initially wear glasses. Astigmatism increases and causes continuing problems. Ectasia can occur in both Lasik and PRK/LASEK surgery. There are tell-tale signs on the cornea that can be picked up using sophisticated corneal mapping, biomechanic checks, and corneal epithelial thickness mapping.

Prevention

1. The best person to determine whether you are at risk or not is a surgeon who has specialized in the Cornea. Specialized corneal surgeons are trained and experienced with Keratoconus, a condition where the cornea is elastic and bulges. They are very familiar with the type of tests used to check for this condition and subtle signs of the disease.

2. Ask if three-dimensional tomography devices like the Pentacam are being used to evaluate the cornea.

3. Does the center use biomechanical checks to determine corneal elasticity.

5. Flap complications

Flap complications such as buttonholes, partial flaps, irregular fragmented flaps have been reported in Lasik laser eye surgery, where a bladed microkeratome is used to create the flap.

Following the introduction of the IntraLase femtosecond laser for flap creation (introduced by Centre for Sight in 2004), flap complications are now thankfully rare. Use of the femtosecond laser is the gold standard, and blade microkeratomes that in the past were responsible for flap complications should no longer be used.

Prevention 

  1. Ask the treating center if the IntraLase laser will be used for creating the corneal flap in the LASIK procedure
  2. Ask your surgeon how long they have performed LASIK and for how long they have used IntraLASE.

Final Words 

Laser eye surgery is a fantastic procedure that is liberating. You must make a good choice. Becoming well educated is a good first start. Next, find a good surgeon and eye center who can deliver exceptional care. A good tip is to go where other eye surgeons go for their care.

5 Early Signs You Need Laser Eye Surgery

Laser eye surgery completely removes eye problems at any damage level and provides clearer vision. It is the best available option to treat severe eye conditions such as nearsightedness: farsightedness, and astigmatism. 

Laser eye surgery is quick and painless. If you are working with the right surgeon with vast experience, he can perform the procedure in less than an hour without causing any complications whatsoever. Laser eye surgery involves using a laser to reshape a patient’s cornea and remove all the irregularities in the eye to give the patient a clearer vision.

What seems to be the twist is that glasses can also reshape the cornea the same way, making changes to how light travels to the patient’s retina and perfectly correcting the vision of the affected eye. If you are going through laser eye surgery, all of that correction will happen within a few minutes.

However, it is somewhat alarming that as much as laser eye surgery can give people the perfect vision they have ever imagined, most people hesitate to go for it even when they are due for it. As an expert, I have learned that people tend to run away from laser eye surgery because they cannot determine whether they need the surgery or just get corrective glasses or contact lenses. 

In light of that, I deem it necessary to let you know the right time you should go for laser eye surgery so that you will not cause damage to your eyes while going for other options.

5 Early Signs You Need laser Eye Surgery 

1. You can’t see correctly at night 

Not many people see well at night, but they always resolve that it’s normal since it’s dark. Have I seen several claiming that they can’t drive at night because they always experience poor sight at night? Do you have the same issues? Do you have difficulty seeing at night? If your answer is yes, you need to go for laser eye surgery.

Meanwhile, it is easy to make poor vision at night for granted. Most likely, you will want to think it is not something worth laser eye surgery. Since you see better during the day, you can blame the various flashlights that shine at night, either from the street lights or oncoming cars. learn more about night blindness by clicking here.

Contrary to what you are thinking, let me be the one to tell you that night blindness is an eye problem that requires laser eye surgery procedure. Night blindness may cause you to have difficulty walking at night or seeing properly in a dimly lit space. It may also be the reason you can see what is happening around you at night without streetlamps. 

Laser eye surgery is the best option to reverse night blindness nearsightedness, and it doesn’t take much time to finish the entire procedure. 

2. Your vision is a blur

When you expose your eyes to too many rays of light that emit from the screen of your computer, television, or even smartphones, you may begin to experience poor vision. In other words, your eyes will not catch images precisely the way they look. You will start squinting while operating your computer, reading texts on your smartphone, or watching an exciting movie from a close or far distance. 

Mind you, squinting is not the ideal way of seeing; you only do that to compensate for your impaired vision. Having a blurry sight or seeing haloes around every object you look at night suggests that your eyes are not getting the right amount of light it needs, which can signify near or farsightedness

Blur vision is a sure sign that you need laser eye surgery. Although glasses and contact lenses can also help correct your blurred vision, laser eye surgery provides the best and lasting solution. 

You don’t have to wait until your blurry vision gets to a worse stage before you start considering going for laser eye surgery. Visit an expert surgeon and discuss your eyes issues to know whether you are qualified for the procedure or not.  Click here to read about 5 Side Effects of Laser Eye Surgery and How to Prevent Them.

3. Your headaches or you experiencing eye strain 

When you are constantly involved in strenuous activities every day, it is expected that you will experience fatigue or eye strain, or your eyes start to feel heavy. Although you might think the best way to solve those problems is to refrain from strenuous activities, if the problem persists, it might be that you need laser eye surgery. 

Strenuous activities are dangerous to your eyes. They can pose severe damages to your vision and even delay recovery when healing from the effect of LASIK surgery. You might keep experiencing constant headaches if your eyes are trying to adjust for impaired vision. When your eyes keep adjusting themselves for poor vision, it can cause pain in the head.

In the same vein, frequent headaches might be a symptom of astigmatism or farsightedness. 

4. You can’t perform daily activities adequately 

One of the easiest ways to know you need laser eye surgery is to check how easy it is to perform your daily activities. Suppose you discover that it is somewhat difficult for you to perform daily activities such as reading road signs or interesting novels, driving during the day or night, identifying smaller objects in the vicinity, or even seeing traffic lights. In that case, it is a clear sign that you need to see an experienced eye surgeon negotiate for laser eye surgery

Your eyes play an essential role in your daily activities; when affected, you might be challenging to do the usual chores. Perfect vision aids maximum performance when doing the very everyday activities. 

5. You are no longer comfortable with your glasses

Sometimes, it gets boring moving around with glasses every day. Although glasses can help correct your vision, they have a subtle way of limiting your daily activities. If you are using glasses at the moment, you would remember some odd times when you fell asleep with your glass on, or you wanted to bend to pick something on the ground, and your glasses fell. The result of those moments is always painful. 

So, instead of struggling every day to live your daily life to the fullest, it is better to go for laser eye surgery to get a permanent solution for your impaired vision.

Final Words 

You should go for laser eye surgery when you start seeing the above-mentioned early signs before it worsens. Meanwhile, you will have first to discuss your symptoms with an experienced LASIK surgeon to determine if laser eye surgery is your best solution.
