For millions of people around the world, wearing glasses or contact lenses has been part of everyday life since childhood or adolescence. Short-sightedness, long-sightedness and astigmatism can affect a person’s ability to see clearly without some form of vision correction.
In the 2020s, however, more people are familiar with another option: LASIK eye surgery.
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a form of refractive eye surgery designed to reshape the cornea so that light entering the eye can be focused more accurately onto the retina.
LASIK itself is not new. The procedure has been performed for decades. What has changed is the environment surrounding it.
Advances in laser technology, more sophisticated eye measurements, greater public awareness, improved screening and the growth of modern refractive surgery have made laser vision correction considerably more familiar to today’s patients.
For many people, the idea of having laser eye surgery no longer sounds as unusual as it might have several decades ago.
So why has LASIK become increasingly familiar and commonly considered in the 2020s?
1. LASIK Is No Longer Considered a New Technology
One of the biggest reasons LASIK has become more mainstream is simply that the procedure has existed for a considerable period of time.
When laser vision correction first became available, many patients understandably approached it cautiously. Having a laser reshape the surface of the eye sounded highly futuristic.
Today, the situation is different.
LASIK has been performed internationally for decades, meaning that ophthalmologists have accumulated substantial experience with refractive surgery.
Many people considering LASIK today may even know someone who has undergone the procedure.
It could be a colleague, sibling, friend, spouse or relative.
That familiarity matters.
Instead of LASIK being something patients have only heard about in advertisements or news reports, many people now have direct access to someone who can describe their experience.
This gradual normalisation has helped LASIK become part of mainstream conversations about vision correction.
2. Laser Technology Has Continued to Develop
Modern LASIK is not necessarily identical to LASIK performed many years ago.
Laser systems, diagnostic equipment and surgical planning technologies have continued to develop.
LASIK generally involves reshaping the cornea so that the eye can focus incoming light more accurately. Depending on the technique being used, different laser technologies may be involved in creating the corneal flap and reshaping the underlying corneal tissue.
Modern refractive surgery may incorporate technologies such as femtosecond lasers, wavefront measurements, corneal topography and other sophisticated diagnostic systems.
These technologies can provide ophthalmologists with detailed information about the patient’s eyes.
The ability to obtain increasingly detailed measurements is important because every eye is slightly different.
Rather than simply thinking about a patient as having a particular spectacle prescription, refractive surgeons can evaluate numerous characteristics of the eye before determining whether LASIK may be appropriate.
3. Pre-Surgery Screening Has Become Increasingly Sophisticated
A major part of modern LASIK is what happens before the surgery.
Not everybody who wants LASIK will necessarily be a suitable candidate.
Before recommending refractive surgery, an ophthalmologist may assess factors such as:
- spectacle prescription
- stability of the prescription
- corneal thickness
- corneal shape
- overall eye health
- pupil characteristics
- tear film and dry-eye status
- age
- medical history
- lifestyle requirements
Additional investigations may be required depending on the individual.
Modern diagnostic equipment allows eye-care professionals to examine the cornea in considerable detail.
This is important because identifying patients who may not be suitable for LASIK is an essential part of refractive surgery.
For example, certain corneal abnormalities may make LASIK inappropriate or require consideration of a different approach.
Consequently, technological improvements have not simply changed how LASIK is performed. They have also improved how patients are evaluated beforehand.
4. People Are Becoming More Aware of Their Vision-Correction Options
Twenty or thirty years ago, many people with myopia simply assumed that their choices were glasses or contact lenses.
Today, patients are generally more aware that multiple forms of refractive surgery exist.
LASIK is probably the best-known name, but it is not the only procedure available.
Depending on the patient’s eyes and circumstances, an ophthalmologist may discuss alternatives such as PRK, SMILE or implantable lenses.
This broader awareness has helped create a more developed refractive-surgery industry.
Patients are also able to research procedures online before visiting an ophthalmologist.
They can learn basic terminology, understand the questions they should ask and compare different approaches.
However, online research should complement rather than replace a professional eye examination. Whether someone is suitable for a particular procedure can only be determined after appropriate clinical assessment.
5. Modern Lifestyles Can Make Freedom From Glasses Appealing
Glasses are a simple and effective form of vision correction, and many people are perfectly happy wearing them.
For others, however, glasses can sometimes be inconvenient.
This can become particularly noticeable during exercise and outdoor activities.
Running, cycling, swimming and certain competitive sports can make spectacles less practical. Glasses may move, become wet or fog up under particular conditions.
People with relatively high prescriptions may also be heavily dependent on their glasses from the moment they wake up.
Contact lenses provide another solution, but they also require appropriate hygiene, handling and ongoing replacement.
For some patients, therefore, reducing dependence on glasses or contact lenses can be one reason to investigate LASIK.
It is important to emphasise that LASIK does not guarantee that a person will never require glasses again.
Vision can change over time, and age-related changes can still occur.
Nevertheless, the possibility of reducing dependence on corrective eyewear can be attractive to suitable patients.
6. The Experience of Surgery Can Be Relatively Quick
Another reason LASIK attracts attention is that the actual procedure can be relatively quick.
Although patients need to spend time undergoing assessment, preparation and post-operative care, the laser portion of LASIK does not normally involve spending hours in an operating theatre.
The procedure is generally performed as day surgery.
Patients will normally need someone to accompany them home and should follow the surgeon’s post-operative instructions carefully.
The relatively short procedural time makes LASIK very different from what some patients imagine when they hear the word “surgery”.
However, the fact that LASIK can be performed quickly should not lead patients to underestimate it.
LASIK is still surgery involving the eye and should therefore be approached seriously.
7. Recovery Can Be Relatively Fast for Many Patients
LASIK is also known for relatively rapid visual recovery compared with some other forms of refractive surgery.
Many patients notice significant improvement relatively soon after the procedure, although individual recovery varies.
Temporary symptoms may occur during recovery, and patients usually attend follow-up appointments so that the ophthalmologist can monitor healing.
Patients should carefully follow instructions regarding eye drops, eye rubbing, exercise, swimming, cosmetics and other activities following surgery.
The possibility of returning to many normal activities relatively quickly can make LASIK attractive to working adults who may find a prolonged recovery period difficult.
However, “fast recovery” should not be confused with “no recovery”.
The eyes still need time to heal, and the surgeon’s advice should always take priority.
8. Social Media Has Increased Awareness of LASIK
The rise of social media during the 2010s and 2020s has also contributed to awareness.
People regularly share their experiences of medical and aesthetic procedures online.
LASIK is no exception.
Videos documenting LASIK consultations, surgery days and recovery experiences can be found across social platforms.
This exposure has made refractive surgery more visible.
Someone who had never seriously considered LASIK may encounter a video from a friend, influencer or public figure discussing their experience and subsequently decide to research the procedure.
There is, however, an important limitation.
Individual experiences shared online should not be treated as medical evidence.
A procedure that was suitable for one person may be unsuitable for another.
9. The Growth of Myopia Has Increased Interest in Vision Correction
Myopia, or short-sightedness, represents a substantial global eye-health issue.
It is particularly significant in parts of East and Southeast Asia, where myopia prevalence is high.
A larger population requiring vision correction naturally means a larger population that may eventually investigate alternatives to glasses and contact lenses.
This is especially relevant when younger generations who have worn glasses since childhood reach adulthood.
Someone who has depended on glasses for ten or fifteen years may begin investigating whether refractive surgery could reduce that dependence.
LASIK does not address the underlying public-health causes of increasing myopia, and refractive surgery should not be confused with myopia-control strategies for children.
Instead, LASIK corrects refractive error in appropriately selected adult patients.
10. Patients Have More Information Available to Them
Healthcare information has become significantly easier to access.
Patients can now read about:
- how LASIK works
- potential benefits
- possible complications
- eligibility criteria
- recovery
- alternative procedures
- costs
- surgeons and clinics
Many hospitals and ophthalmology centres publish educational information about refractive surgery.
This availability of information can make patients more comfortable asking questions during consultations.
At the same time, the quality of online information varies substantially.
Medical decisions should therefore be based on consultation with an appropriately qualified eye-care professional rather than marketing material or social-media testimonials.
11. LASIK Can Appeal to Contact-Lens Users
Some long-term contact-lens users eventually become interested in refractive surgery.
Contact lenses can provide excellent vision correction, but they require regular care.
Depending on the type of lenses being used, patients may need to purchase replacement lenses and cleaning products continuously.
Contact-lens hygiene is also extremely important because improper use can increase the risk of eye problems.
Some users may additionally experience discomfort or dry-eye symptoms associated with lens wear.
For certain patients, years of contact-lens use can eventually lead them to investigate whether laser vision correction is an appropriate alternative.
That does not mean LASIK is automatically safer or better for every contact-lens wearer.
Each option has different advantages, limitations and risks that should be discussed with an eye-care professional.
12. Greater Competition Has Made LASIK More Accessible
The growth of refractive surgery has also resulted in more hospitals, eye centres and specialist clinics offering laser vision-correction procedures.
In major cities, patients may have access to multiple ophthalmologists and different refractive-surgery technologies.
Greater availability has made LASIK easier to investigate than it once was.
Patients may be able to attend an initial assessment, compare procedures and obtain information about suitability without travelling overseas or to a distant specialist centre.
However, patients should avoid choosing a medical provider purely according to price.
The surgeon’s qualifications, clinical assessment, technology, aftercare arrangements and explanation of potential risks are important considerations.
13. LASIK Fits Into a Broader Shift Towards Personalised Healthcare
Healthcare in the 2020s is increasingly focused on individualised treatment.
LASIK reflects this trend.
Modern refractive-surgery planning may involve detailed measurements of an individual’s cornea and optical characteristics.
Different patients may therefore receive different recommendations even if their spectacle prescriptions appear similar.
One person might be considered suitable for LASIK.
Another may be better suited to a different refractive procedure.
A third person may be advised to continue wearing glasses or contact lenses.
The goal should not simply be to perform LASIK on as many people as possible. Appropriate patient selection is fundamental to responsible refractive surgery.
Is LASIK Suitable for Everyone?
No.
Despite its increasing popularity and technological development, LASIK is not appropriate for every patient.
Suitability depends on numerous factors including age, prescription stability, corneal characteristics, general eye health and medical history.
Certain conditions or anatomical characteristics may make LASIK unsuitable or increase risk.
Pregnancy and certain medications or medical conditions may also affect when refractive surgery should be considered.
A comprehensive assessment by a qualified ophthalmologist is therefore essential.
What Are the Potential Risks of LASIK?
LASIK is a surgical procedure, and no surgery is completely without risk.
Potential issues can include temporary or persistent dry-eye symptoms, glare, halos, visual disturbances, under-correction, over-correction and the possibility of requiring additional treatment.
Less common but more serious complications can also occur.
Some patients may still require glasses after LASIK for certain activities.
Ageing also continues after surgery.
For example, presbyopia generally develops as people become older and affects the eye’s ability to focus clearly at close distances. Someone who had excellent distance vision following LASIK at a younger age may therefore still require reading glasses later in life.
LASIK does not stop the natural ageing of the eye.
LASIK Versus Glasses and Contact Lenses
There is no single vision-correction option that is universally “best”.
Glasses are non-invasive, simple and effective.
Contact lenses can provide excellent vision without spectacles but require appropriate hygiene and maintenance.
LASIK can reduce dependence on glasses and contact lenses for appropriately selected patients but involves surgery and associated risks.
The right option therefore depends on the individual.
Some people may happily wear glasses throughout their lives.
Others may prefer contact lenses.
Others may decide that the potential benefits of refractive surgery justify undergoing a professional assessment.
The Future of Laser Vision Correction
Refractive surgery will likely continue evolving beyond the 2020s.
Improvements in imaging, diagnostics, laser technology and surgical planning may allow ophthalmologists to evaluate patients with even greater precision.
At the same time, LASIK is now only one part of a broader refractive-surgery landscape.
Different laser and lens-based procedures allow ophthalmologists to consider multiple approaches depending on the patient’s eyes, age, prescription and lifestyle.
The future may therefore be less about one procedure becoming dominant and more about selecting the most appropriate vision-correction technique for each individual.
Conclusion
LASIK has become considerably more familiar in the 2020s because several developments have occurred simultaneously.
The procedure now has decades of clinical history. Laser and diagnostic technologies have continued to improve. Pre-operative screening has become increasingly sophisticated. Patients have greater access to information, while social media and word of mouth have made refractive surgery much more visible.
Modern lifestyles have also increased interest in reducing dependence on glasses and contact lenses, particularly among people who exercise frequently, participate in sports or have worn corrective eyewear for many years.
At the same time, increasing popularity should never be interpreted as meaning that LASIK is appropriate for everyone.
LASIK remains an eye surgery with potential benefits, limitations and risks. A comprehensive eye examination and consultation with a qualified ophthalmologist are necessary to determine whether LASIK—or another form of vision correction—is appropriate for a particular individual.
The most significant change in the 2020s may therefore not simply be that more people have heard about LASIK. It is that refractive surgery has become a much more established part of the broader conversation about how adults can manage their vision and dependence on corrective eyewear.
