Difference between Lasik, PRK laser eye surgery sydney

These two laser eye surgery procedures can accurately treat eye injury and eye diseases and also can do vision correction. Lasik and Photorefractive Keratectomy laser eye surgery sydney have procedures that combat short-sightedness, long-sightedness, and vision problems.

But keyhole surgery is different from that of Lasik and PRK surgery. Another surgery is of refractive surgery, and this surgery discontinues glasses prescription. It is also known as laparoscopic surgery. This laser eye surgery can discover so many conditions in the body.

The main point of this article is centered on Lasik and PRK laser eye surgery sydney. Before any patient goes for any laser eye surgery, you first consult a laser eye clinic to know the one you are a suitable candidate for.

Even though both Lasik and PRK laser eye surgery sydney reshapes the cornea but different laser eye surgery procedures are based on the diagnostics test. In this article, I’ll discuss the differences and how vision problems are solved, and the laser eye surgery procedure between Lasik and PRK surgery.

Difference between Lasik, PRK laser eye surgery

Operations of PRK

Some things happen during the laser surgery of PRK that is different from Lasik laser surgery. We’ll be checking the operations of PRK.

  1. The surgeon will recommend contact lenses to aid your vision correction and healing after the laser surgery is done through the medical procedure
  2. This enhancement procedure hastens your healing and gives you comfort.
  3. Using a laser helps the laser eye surgeon reshape your corneal tissue quickly without stress.
  4. Also, the corneal epithelium, which is the outer layer, is removed with the use of a brush.
  5. There are laser treatments you will be given to calm you down before the surgery is carried out and to rectify the vision problems

You will also be given eye drops for at least a week to make you feel no pain while the laser eye surgery sydney procedure continues. And also, contact lenses are recommended. 

Operation of Lasik laser eye surgery

Advanced surface laser ablation photorefractive keratectomy, just like Lasik eye surgery, the excimer laser is also used to address and reshape the corneal tissue and refractive error. When the corneal adjust itself back to its place, then the process completes the laser eye surgery sydney.

In LASIK Surgery, the eye surgeon makes a small flap in the corneal epithelium, which is different from the laser eye surgery procedures of PRK.  

The Healing Process between PRK and LASIK Laser Eye Surgery

The healing process and recovery between both are pretty different in laser eye surgery. It only takes a few hours for Lasik eye surgery to heal, and the recovery period is not farfetched, unlike the Photorefractive keratectomy

Meanwhile, anything can happen if precautions are not taken seriously after the laser eye surgery, no matter the surgery you underwent.

The Healing Process of PRK Laser Eye Surgery

1.    Healing takes a few days in Photorefractive keratectomy. Sometimes it may take a month or more for total healing and recovery. Laser Vision correction can only be achieved when there is total healing. This will involve a follow-up appointment with the eye surgeon candidate for this laser vision correction can only return to their daily activities routine when the contact lenses are removed.

2.    When the corneal is healing, you may have blurry vision, irritation, and burning. The eye surgeon will give you some drugs to reduce the pain for some days after laser treatment. Meanwhile, eye drops will also be recommended for you, and also to wear contact lenses. Sometimes eye surgeon might give a glasses prescription.

3.    The bandage contact lenses can only be removed when the eye is healed, giving you a perfect and working sight. The essence of contact lenses is to make the cornea heal when placed on the surface layer of the laser eye.

The Healing Process of LASIK

1.    In Lasik eye surgery, sometimes, in between hours, you may experience discomfort, but it will only last for hours, not too long to bear. But after the laser eye surgery treatment, you will be given pain relief, and eye drops to apply.

2.    The healing and recovery process of Lasik is faster than that of Photorefractive keratectomy laser eye surgery because of the approach of the medical procedure. Many patients may even return to their respective practice that same day of the laser eye surgery.

Suitable candidate to perform laser eye surgery

Some conditions fit into being a candidate for laser eye surgery.

  1. Pregnant or nursing mother.
  2. 5-6mm is the average pupil size required.
  3. Suitable candidate for the surgery must be above 20

There are so many things responsible for laser eye surgery costs. There are many laser eye surgery options with low and high costs.

  1. Lasik eye surgery costs $1000 to $2600 for one surgery.
  2. PRK laser eye surgery costs from $2000 to $4000 for the two eyes.
  3. During post-surgery, PRK patients must visit the surgeon regularly, which can cost more, like Lasik surgery.
  4. Two Lasers are used for the operation in Lasik. One is used to open the flap, while the other laser is used to shape the cornea.
  5. But in PRK laser surgery, one laser is used in the surgery to reshape the corneal flap.

Do and don’t of PRK

There are do and don’t of PRK and Lasik corrective eye procedures.

  1. As for PRK, the healing time is longer.
  2. The bandage or contact lenses must be removed before a patient can drive. One of the compelling Don’t is that driving is prohibited for a particular time till you have proven healed.
  3. It is also preferable for the patient to have thin corneas
  4. Sometimes, total recovery may be tough to get, but gradually it will add up. Vision correction takes patience, or the eye disease or eye injury may reoccur anytime.

  6. The corneal flap is free from any risk or complication.


Do and Don’t of Lasik surgery

  1. Lasik surgery has a speedy recovery procedure.
  2. Getting an eye infection is not sure or less risky.
  3. Lasik eye surgery does not need the use of bandage contact lenses
  4. Patient can drive a day after the surgery is done.
  5. Lasik eye surgery can generate a significant risk of having poor or blurred vision at night.

This article has opened your eyes to the fact that there are several differences between Lasik and PRK laser eye surgery. In terms of laser eye surgery, laser eye treatment, eye drops, and even antibiotics drugs, distant objects, cloudy vision, short-sightedness, long-sightedness, and enhancement procedures, all of which are enshrined in laser eye surgery.

As good as contact lenses are, laser eye surgery will do vision correction perfectly. This is essential information that you will find many answers to the questions about eye surgery bothering your heart. Your distance vision can be corrected with laser procedures.

Laser Eye Surgery: Is SMILE a better alternative?

The Small Incision Lenticule Extraction, also known as SMILE surgery, is the latest and safely modified laser vision correction method. This laser eye surgery is an advanced method involving laser treatment to correct different eye defects.

This method effectively corrects short-sightedness, long-sightedness, astigmatism, and other vision correction procedures. Before the invention of SMILE, LASIK eye surgery procedures were the more common type of laser eye surgery medical procedure.

By the way, LASIK stands for Laser-assisted In-situ keratomileusis, the first prominent laser surgery for vision correction. It is a laser treatment method that requires working on the corneal tissue by making a corneal flap with a cold laser.

What is SMILE – the Small Incision Lenticule Extraction?

The SMILE procedure is a type of laser eye surgery that involves the creation of a small incision on the eye’s cornea. Then the laser eye surgeon applies the laser to remove just a thin layer of tissue from the surface, called the lenticule.

The incision helps extract the lenticule, reshaping the cornea and modifying it for better vision in the patient. The SMILE process is one of the least invasive laser eye surgery to correct eye diseases, especially myopia (short-sightedness) and astigmatism.

Over 5,000,000 SMILE eye procedures have been successful by over 2,500 laser eye surgeons worldwide. Therefore, this particular laser eye surgery is one of the fastest-growing eye correction surgery anyone could think of around the globe.

Why is SMILE different?

The SMILE procedure of laser eye surgery can be a safer alternative to LASIK due to the absence of postoperative restrictions. For example, after having a LASIK eye surgery, the patient cannot wear makeup or play sports immediately afterward.

Meanwhile, the SMILE procedure allows the patient to do these activities conveniently after laser eye surgery. In addition, the SMILE eye procedure does not require raising a cornea flap. Another difference is that this procedure is much less invasive on the eye’s cornea.

Compared with the LASIK eye procedure, it is less invasive because it only requires a small incision, unlike the LASIK surgery. In LASIK, the laser eye doctor must create a flap in the cornea. The entire laser eye surgery takes about 30 seconds for each eye to complete.

Another difference is the short time of recovery after laser eye surgery. After undergoing a SMILE eye procedure, the patient can recover more quickly with less discomfort than other laser eye surgery options. Patients compare eye treatment with wearing contact lenses.

However, the downside is that this procedure is not suitable for everyone. One will have to undergo some preliminary tests to confirm suitability for this laser eye surgery. Only an eye doctor can confirm after examination if SMILE is suitable to correct your eye defect.

How safe is SMILE Eye Surgery?

However, does an overall consideration show that SMILE eye surgery is a different alternative for vision correction? For example, is it better to stick to reading glasses or wear contact lenses even after laser eye surgery? Those are a few questions that this article will answer about laser eye surgery.

There is no doubt about the efficiency and safety of using the SMILE for eye corrections, as millions of people have already proven. This laser eye surgery has been successful in millions of cases who still enjoy a perfect vision than they have ever had.

Moreover, it does not involve any post-surgery issues, complaints, or side effects associated with other laser eye surgery procedures. After the SMILE eye procedure, patients can resume normal activities, including doing sports, working out, and wearing makeup.

However, kindly note that an eye disease such as long-sightedness requiring some specific prescriptions can not be resolved with the SMILE procedure. At best, the patient must see a laser eye surgeon to recommend the best vision correction procedure.

Are Contact lenses safe?

Many people have asked us this question repeatedly, and we will give the best answer. Contact lenses offer temporary vision correction to many people across America and Australia when worn and cared for correctly.

However, a primary issue often associated with using contact lenses for a long time is contact lens intolerance (CLI). But what is CLI as it applies to using SMILE in laser eye surgery options? Already over 5 million Americans who wear contact lenses experience contact lens intolerance.

In this case, the eyes can no longer be corrected after prolonged use of contact lenses because the eyes and the brain have had slight changes in their response and functions.

Laser Eye Surgery: Is SMILE a better alternative?

Some risks of using Contact Lenses

Apart from contact lens intolerance (CLI), some risks are associated with choosing contact lenses to correct eye defects. Some are stated below

  1. Corneal infiltrates – in this case, some small gray or white bumps may appear on the surface of the eye
  2. Papillary conjunctivitis – this condition is an inflammation of the inner eyelid that can affect one’s vision
  3. Corneal abrasion occurs because of tampering with the eyes or scratching the eyes while inserting or removing the contact lenses.
  4. Corneal neovascularization – insufficient oxygen supply to the eye can lead to the swelling of the cornea. The overuse of contact lenses causes this condition.
  5. Infectious Keratitis – Continuous contact lenses can lead to this infection that affects the corneal, leading to corneal ulcers.

Which is safer: SMILE Laser Eye Surgery or Contact Lenses?

There are merits and demerits of both the SMILE laser eye surgery and the use of contact lenses. But determining which of the two options is more suitable for anyone suffering from eye defects is not always easy.

The best way to determine which works better is to consult a trained eye care specialist. The first step is to consider the symptoms of your eye defect to determine what it is. After diagnosing the issue, the doctor recommends a suitable laser eye surgery.

For instance, are you suffering from hyperopia (long-sightedness), myopia (short-sightedness), or astigmatism? The last two can be corrected using the SMILE eye procedure, while hyperopia is somewhat corrected with contact lenses. So far, the SMILE procedure is still the safest option.

As for the contact lens, we have stated some of the reported issues that patients often have. However, using SMILE eye treatment eliminates the likelihood of other eye injuries, ulcerations, and the risk of eye infections.

In addition, it depends on the laser eye clinic you choose and the laser eye surgery cost to deal with your blurry vision, poor distance vision, and other eye defects once and for all. Laser eye surgery that may involve a computer-controlled excimer laser eye surgery procedure can produce incredible results.


Going for SMILE has many advantages over LASIK eye surgery as an advanced surface laser ablation or refractive surgery. Alternatively, patients have been wearing glasses prescription or contact lenses in place of a medical procedure. Also, there should not be any fear in choosing any laser procedures, especially if you want permanent vision correction.
