LASIK Surgery: A Guide To Potential Risks And Side Effects

Wearing glasses may feel like second nature to some, becoming an accessory that blends seamlessly into daily life. For these individuals, putting on a pair of spectacles is as routine as brushing their teeth. Glasses can even become part of a personal style statement, offering both functionality and fashion.

For others, however, glasses may feel like an inconvenience. Depending on your profession or lifestyle, they may get in the way. Imagine working in a kitchen with constant steam fogging up your lenses, or playing sports only to have your glasses slip off at the most critical moment. Some people also find glasses uncomfortable or struggle with the maintenance that comes with them. Those that wear contact lenses may also run into issues like allergy, dry eyes and infection. It is not surprising that more individuals are exploring vision correction options such as laser eye surgery.

 

Understanding LASIK eye surgery

LASIK, short for Laser-Assisted in Situ Keratomileusis, is one of the most common types of laser eye surgery performed worldwide. During the surgery, a specialised laser is used to carefully reshape the cornea so that incoming light can properly focus on the retina. This correction can improve conditions such as short-sightedness, long-sightedness, and astigmatism.

For those considering LASIK eye surgery in Singapore, the appeal lies in the possibility of achieving clear vision without the need for glasses or contact lenses. Many patients experience dramatic improvements in their sight within a day or two after the procedure, making it an attractive solution for those frustrated by their dependence on corrective lenses.

While LASIK is known for its high success rate, it is equally important to be aware of the potential risks and side effects before making a decision.

 

Common side effects of LASIK surgery

Although LASIK is generally considered safe, like any medical procedure, it is not completely free of side effects. Some of the more common issues experienced by patients include:

 

1. Dry eyes

One of the most frequent side effects after LASIK surgery is dryness in the eyes. This occurs because the surgery temporarily affects the nerves responsible for tear production. Most people notice improvement within a few weeks to a few months, but in some cases, dry eye symptoms can linger. Artificial tears are often recommended to help relieve discomfort.

 

2. Fluctuating vision

It is normal for vision to fluctuate during the healing period. Some patients may notice that their sight appears sharper at certain times of the day and blurrier at others. This usually stabilises after a few weeks as the eyes heal, but patience is essential during this stage.

 

3. Glare, halos, and starbursts

Some individuals report increased sensitivity to light or visual disturbances such as glare, halos, or starbursts around lights, especially at night. These effects are typically temporary but can feel unsettling, particularly when driving in low-light conditions.

 

4. Overcorrection or undercorrection

Individuals respond to treatment slightly differently. This is the same in LASIK, different eyes will absorb the laser energy slightly differently, leading to overcorrection or undercorrection of vision. This means that a person may still need glasses, contact lenses, or, in some cases, an additional enhancement procedure to fine-tune the results.

 

Rare but serious risks

While complications from LASIK are rare, it is important to understand that they can occur.

 

1. Infection and inflammation

Any surgical procedure carries a small risk of infection or inflammation. With LASIK, these risks are minimised through the use of advanced surgical techniques and post-operative medication (eye drops), but they are not eliminated entirely. Prompt medical care can usually resolve such issues.

 

2. Corneal ectasia

Though very uncommon, LASIK may sometimes reduce corneal strength, resulting in a complication known as corneal ectasia. This results in progressive thinning and bulging of the cornea, which can cause significant vision problems. Pre-surgery screening is designed to reduce this risk by identifying patients who have risk factors for this, such as thin cornea, uneven cornea shape and very high degrees of spectacle correction.

 

3. Reduction of vision

Although exceedingly rare, there is a very small chance of reduced best-corrected vision, meaning that even with glasses, a patient may not achieve the same clarity as before surgery. For example, in the rare occurrence of an infection at the center of the cornea caused by a strong germ that heals with a scar. This is one of the reasons why careful evaluation and choosing a reputable clinic are so important.

 

Quick overview of LASIK side effects and risks

Category Possible Effects Typical Outcome
Common Side Effects Dry eyes, fluctuating vision, glare, halos, starbursts, over/undercorrection Usually temporary and improve within weeks to months
Less Common Complications Prolonged dry eyes, need for enhancement procedure Manageable with treatment or additional surgery
Rare but Serious Risks Infection, inflammation, corneal ectasia, reduction in vision Very uncommon, minimized by pre-op evaluation and use of medication

 

Deciding whether LASIK is right for you

Before undergoing LASIK, it is crucial to undergo a comprehensive eye assessment. Factors such as corneal thickness, eye health, and overall medical history play a major role in determining whether you are a suitable candidate. Not everyone will qualify for the procedure, and in such cases, alternative treatments may be recommended.

Patients should also understand that LASIK does not prevent age-related changes in vision. For example, presbyopia, which commonly affects people over 40, may still require the use of reading glasses later in life. Similarly, questions such as if blurry vision is a normal sign of ageing or early sign of cataracts should be discussed with an eye specialist to avoid confusion.

Another point to consider is lifestyle. Those with highly active or physically demanding jobs may want to discuss their suitability with their surgeon. While LASIK has helped millions around the world, ensuring that it fits your long-term needs is key to satisfaction.

 

Managing expectations

A vital part of deciding on LASIK is having realistic expectations. While most patients enjoy excellent results, the goal of surgery is improvement, not perfection. For some, this may mean enjoying near-perfect vision, while others may still rely on glasses in specific situations, such as night driving or reading small print.

It is also helpful to keep in mind that recovery takes time. Immediate improvement is common, but full healing may take several months. Following all post-surgery instructions, attending scheduled follow-ups, and reporting any unusual symptoms will help ensure the best possible outcome.

 

Conclusion

LASIK surgery offers a life-changing opportunity for many individuals to reduce or eliminate their reliance on glasses or contact lenses. However, like all medical procedures, it comes with potential risks and side effects that should not be overlooked. Understanding what to expect, from common issues like dry eyes to rare complications, can help you make an informed decision about whether LASIK is right for you.
