Pros And Cons Of Lasik Eye Surgery

If you need glasses the first thing in the morning, you’ve probably already looked up LASIK surgery on the internet by now. LASIK surgery has been around for decades and has proven transformational for those looking to restore their vision. But is it worth all the hype? Before you make up your mind to undergo this surgery, it is crucial to weigh all the pros and cons of LASIK.

In this blog, we’ll deep dive into all the pros and cons of LASIK and help you make an informed choice.


What is LASIK Surgery?

LASIK eye surgery, a revolutionary advancement in the field of ophthalmology, gives hope for millions of individuals whose quality of life has been plagued by vision impairments such as nearsightedness, farsightedness, and astigmatism. 

Before jumping to the pros and cons of LASIK, let’s explore several key steps, each critical to the success of the procedure and the improvement of the patient’s vision:

  1. Creating the Corneal Flap: Utilizing advanced technology, either a femtosecond laser or a microkeratome, a thin flap is precisely created on the surface of the cornea.
  2. Lifting the Flap: This newly created corneal flap is carefully lifted to expose the underlying corneal tissue, preparing it for reshaping.
  3. Reshaping the Cornea: An excimer laser is then employed to accurately reshape the cornea, correcting the vision by focusing on specific refractive errors. This step is meticulously carried out to ensure surrounding tissues remain unharmed.
  4. Repositioning the Flap: After the cornea has been reshaped, the flap is gently placed back over the corneal surface where it naturally adheres, removing the need for stitches.


The whole procedure is usually just about 15 minutes for both eyes, performed under the gentle numbing effect of local anaesthesia, making it a comfortable and pain-free experience from start to finish. Still wondering what are LASIK surgery side effects? Let’s dive into the pros and cons of LASIK right away.

Understanding Pros and Cons of LASIK

The first thought when someone thinks about this surgery is whether LASIK surgery side effects are real. Though LASIK eye surgery is widely known for its potential to significantly improve vision, it comes with its own set of advantages and disadvantages. Here’s a comprehensive look at the pros and cons of LASIK:

Pros of LASIK Eye Surgery

  • High Success Rate: Most patients achieve 20/20 vision or better.
  • Quick Recovery: Many see improvement almost immediately, with minimal downtime.
  • Long-lasting Results: Vision improvement is typically permanent, with adjustments needed only for age-related changes. 
  • Cost-Effective Over Time: Can be more economical than the long-term cost of glasses or contact lenses. 
  • Lifestyle Benefits: Reduces or eliminates dependence on glasses or contact lenses, offering freedom in daily activities.
  • Painless Procedure: Performed under local anaesthesia with minimal discomfort during the surgery.

Cons of LASIK Eye Surgery

  • Surgical Risks: Potential for complications, though rare, such as infection or flap issues.
  • Temporary Discomfort: Some experience dry eyes, glare, halos, or fluctuating vision initially.
  • Not Suitable for Everyone: Not recommended for individuals with certain eye conditions, severe myopia, or unstable vision.
  • Not covered under insurance: Initial cost can be high and is not typically covered by insurance.
  • Revision Surgeries: Some patients may require additional surgeries to achieve desired vision correction.
  • Irreversible: Changes made to the cornea cannot be reversed, though adjustments can be made.


Considering these advantages and disadvantages of LASIK is crucial for anyone contemplating LASIK eye surgery risks. It’s important to discuss all aspects with a qualified ophthalmologist to make an informed decision based on your specific vision needs and health conditions.

LASIK Eligibility Criteria and Consultation Process

Wondering if you should go for this procedure? Let us help you determine whether you are eligible for LASIK eye surgery.

LASIK Eligibility Criteria

  • Age: Must be 18 or older, preferably mid-20s for stabilized vision.
  • Vision Stability: No prescription changes for at least one year.
  • Eye Health: No eye diseases (e.g., keratoconus, glaucoma), severe dry eyes, or infections.
  • Corneal Thickness: Sufficient for flap creation and reshaping.
  • Pupil Size: Consideration of potential side effects for those with large pupils.
  • Overall Health: No autoimmune diseases or conditions impacting healing.
  • Refractive Error Limits: Specific ranges for nearsightedness, farsightedness, and astigmatism.


Now that you are aware of all the pros and cons of LASIK, consider a thorough consultation for LASIK surgery. It is not only crucial for assessing eligibility but also for providing a personalized evaluation tailored to each patient’s unique needs. This stage is essential for educating patients about the advantages and disadvantages of LASIK, and a detailed review of health and eye history is vital for identifying any potential complications. Pre-surgery assessments, including detailed eye exams and diagnostic tests, play a significant role in customizing the procedure to ensure safety and effectiveness. By evaluating lifestyle and vision requirements, eye care professionals can offer bespoke advice and treatment plans, maximizing the procedure’s success and patient satisfaction with the outcome. 

Alternative Vision Correction Methods Over LASIK Eye Surgery

LASIK eye surgery is renowned for its efficiency in correcting a wide range of vision problems with a high success rate and minimal recovery time, making it a popular choice among vision correction methods. To avoid LASIK surgery side effects, you might opt for alternatives like PRK, SMILE, SILK, LASEK,and  Implantable Collamer Lenses (ICLs), which cater to specific needs, such as thinner corneas or lifestyle preferences. LASIK stands out due to its quick procedure, rapid recovery, and ability to significantly improve nearsightedness, farsightedness, and astigmatism. Its widespread success and the convenience of a flap-based correction method make it a preferred option for many seeking a permanent solution to refractive errors, offering a life relatively free from glasses or contact lenses.

Long-Term Effects and Maintenance of LASIK

After going through all the pros and cons of LASIK, you may want to conclude that LASIK is a safe and healthy procedure for your eyes. While there are lesser LASIK surgery side effects, the longevity of LASIK results and the considerations for long-term eye health are key aspects of the decision to undergo this popular vision correction surgery. Most patients who undergo LASIK enjoy a significant improvement in vision that can last for many years. The stability of the results, however, may vary due to individual factors such as age, the original degree of refractive error, and the natural ageing process of the eye, such as the development of presbyopia or cataracts.

Immediate post-surgery care is crucial to avoid LASIK eye surgery risks. This includes following doctor’s instructions and using eye drops to prevent infection. Regular eye check-ups are essential to monitor eye health and the stability of LASIK results, and some may require enhancement procedures over time for optimal vision. Protecting eyes from UV light and injury is also recommended to avoid LASIK surgery side effects. Overall, maintaining good eye health post-LASIK involves routine care and monitoring for any changes.



In wrapping up, the pros and cons of LASIK surgery are essential considerations for anyone pondering this vision correction option. Discussing the pros and cons of LASIK with an eye care professional can provide personalised insights, helping to ensure that the decision to proceed with surgery is well-informed. The procedure offers clear benefits, such as improved vision and independence from glasses or contacts, alongside a swift recovery period. Yet, it’s vital to balance these advantages against lasik eye surgery risks like dry eyes and night vision issues. A detailed discussion about the pros and cons of LASIK with an eye care professional can guide you towards making an informed decision to avoid LASIK surgery side effects. Ultimately, understanding both sides of LASIK allows for a confident and informed choice regarding your vision correction journey.
