What Is iLASIK & How It Is Different From LASIK?


Isn’t it incredible how technological advancements are revolutionizing healthcare? Have you ever wondered about the miracle of vision correction surgeries, the science that lets us rectify our sight? In this article, we’ll take a deep dive into one of the most advanced procedures available today – iLASIK.

We’ll also delve into the differences between iLASIK and its predecessor, traditional LASIK. How have we evolved from the already transformative LASIK to the ultra-precise, ultra-safe iLASIK? Let’s find out!

What Is iLASIK?

What Is iLASIK SurgeryiLASIK, standing for IntraLase LASIK, is a modern, advanced form of vision correction surgery. It’s a bladeless procedure that leverages the latest in laser technology and diagnostic tools to correct common refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

The ‘i’ in iLASIK signifies ‘IntraLase’, a specific type of laser used to create a thin flap in the cornea during the surgery. This method replaces the need for a mechanical blade that was used in traditional LASIK procedures, making iLASIK a ‘bladeless’ surgery, thus enhancing safety and precision.

What truly sets iLASIK apart, though, is its integration of wavefront technology. This technology measures the unique way light travels through your eye, creating a 3D ‘map’ or ‘fingerprint’ of your eye. This map guides the surgeon as they reshape your cornea, allowing for personalized, precise treatment that can often result in vision that’s even better than 20/20.

With its combination of advanced technologies and personalized treatment plans, iLASIK is fast becoming the gold standard in vision correction. It offers the potential for superior results, improved safety, and greater comfort during and after the procedure. Thus, it’s no wonder that iLASIK is seen as the future of vision correction.

Procedure Of iLASIK Vision Surgery

Procedure Of iLASIK Vision Surgery

Now that we know what iLASIK is, let’s look more closely at the surgery itself. It’s a short and painless treatment, and here’s an illustrated guidelines:

Stage 1: Before Surgery

The journey to enhanced vision begins with a comprehensive eye examination. This step is crucial to determine whether you’re a suitable candidate for iLASIK. Your eye doctor will assess your eye health, measure your refractive error, and discuss your lifestyle and expectations.

Two significant processes take place during this examination:

  • CustomVue Wavefront Analysis: This technology creates a 3D map of your eye by measuring how light travels through it. It captures your eye’s unique ‘fingerprint’, which will guide the laser during the surgery.
  • Corneal Mapping: This process uses corneal topography to map the curvature of your cornea and identify any irregularities. These maps are vital for surgical planning.

Before the surgery, it’s advised to stop wearing contact lenses and to keep your eyes free from makeup or lotions to ensure the area is clean for the procedure.

Stage 2: During Surgery

The iLASIK surgery is a two-step procedure that takes about 10 minutes per eye:

  • Creating the Corneal Flap – The IntraLase Method: Using the IntraLase laser, a thin flap is made in the cornea. This bladeless method allows for greater precision and safety compared to traditional LASIK.
  • Reshaping the Cornea – The Wavefront-Guided Method: The surgeon lifts the corneal flap and uses an excimer laser to reshape the cornea based on the CustomVue analysis. The flap is then repositioned, and the surgery is complete.

During the procedure, numbing drops are used to ensure your comfort. You may feel slight pressure, but the process is generally painless.

Stage 3: After Surgery

Post-surgery, you’ll need someone to drive you home as your vision will be blurry. It’s normal to experience some discomfort, burning, or itching sensation in your eyes. However, these symptoms are temporary and should diminish within a few hours.

Your doctor will provide you with eye drops to prevent inflammation and infection and to keep your eyes moist. Avoid rubbing your eyes as it can interfere with the healing process.

Your vision should start to improve within a few days. Most patients can return to their daily activities the next day, but it’s advised to refrain from strenuous activities for at least a week.

Potential Risks & Side Effects Of iLASIK Surgery 

Potential Risks & Side Effects Of iLASIK Surgery Every surgical treatment, no matter how advanced, includes risks and potential adverse effects. Let’s have a look at some of the potential risks and side effects to be aware of:

  • Increased Light Sensitivity: Some patients may suffer increased light sensitivity following iLASIK surgery.
  • Blurred Vision: Immediately following the procedure, you may experience blurred vision. This is normal and should progressively improve in the days following the surgery.
  • Transient Light Sensitivity Syndrome (TLSS): A rare condition, TLSS can cause discomfort in bright light for a few weeks after the surgery.
  • Decreased Visual Clarity Immediately After Surgery: It’s common to have a less-than-perfect vision right after the procedure. Your vision should, however, gradually improve as your eyes heal and adjust.
  • Gritty or Burning Sensation: Some patients describe a gritty or burning feeling in their eyes post-surgery. This sensation usually diminishes within a few hours after the procedure.
  • Infections: As with any surgical procedure, there’s a slight risk of infection. Proper post-operative care and following your surgeon’s instructions can help minimize this risk.
  • Vision Loss or Serious Changes: In rare cases, iLASIK surgery can lead to loss of vision or significant vision changes. These severe complications are uncommon, thanks to the advanced technologies and meticulous techniques used in iLASIK.
  • Flap Healing Problems: During iLASIK, a thin flap is created on the cornea. Occasionally, complications can arise with the healing of this flap, but such instances are relatively rare.
  • Bloodshot Eyes: After surgery, you may notice that your eyes appear red or bloodshot. This is usually a temporary side effect caused by the pressure exerted on the eye during the procedure.

iLASIK vs. LASIK: Which One Is Better?

When it comes to vision correction, LASIK has been a household name for years. However, the introduction of iLASIK has brought a new dimension to the field. But what makes iLASIK different, and is it better than traditional LASIK? Let’s dissect the differences, pros, and cons of each, and make a comparison.

TechniqueUses a mechanical blade (microkeratome) to create a corneal flap. The cornea is then reshaped with an excimer laser.Uses a femtosecond laser to create a corneal flap (bladeless) and wavefront technology to create a 3D map of the eye for a more personalized treatment. The cornea is then reshaped with an excimer laser.
ProsA proven and effective method for vision correction. Quick procedure with fast recovery times. Lower upfront cost compared to iLASIK.The bladeless technique can reduce flap-related complications. Incorporates wavefront technology for personalized treatment and potentially superior vision outcomes. Can treat a wider range of refractive errors.
ConsThe use of a mechanical blade can increase the risk of flap complications. Does not incorporate wavefront technology, potentially leading to less precise corrections.Higher upfront cost compared to traditional LASIK. As a newer procedure, long-term data is less abundant.

So, Is iLASIK Better Than LASIK?

While both LASIK and iLASIK are effective methods for vision correction, iLASIK offers several advancements that could lead to safer procedures and better visual outcomes. The use of femtosecond laser technology reduces the risk associated with creating the corneal flap, and the incorporation of wavefront technology allows for more personalized treatment. However, the choice between iLASIK and LASIK ultimately depends on individual factors, including your eye health, refractive error, lifestyle, and budget. Always consult with a trusted eye care professional to determine the best option for you.
