What Is LASIK?

LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a surgical procedure designed to correct refractive errors. During the surgery, a specialized laser is used to precisely reshape the cornea, the clear front part of the eye. This adjustment ensures that light entering the eye is properly focused, resulting in sharp, clear vision without the assistance of external lenses.

What Vision Problems Can LASIK Treat?

LASIK is highly effective at addressing the most common “refractive errors” that cause blurred vision

• Myopia (Nearsightedness): In people with myopia, the eyeball is too long or the cornea is too steeply curved, causing light to focus in front of the retina rather than on it. Distant objects appear blurry. LASIK flattens the cornea to redirect the focal point onto the retina, improving distance vision.
• Hyperopia (Farsightedness): Hyperopia occurs when the cornea is too flat or the eyeball is too short, causing light to focus behind the retina. Close-up objects are difficult to see clearly. LASIK steepens the peripheral cornea to bring the focal point forward and onto the retina.
• Astigmatism: Caused by an irregularly shaped cornea, astigmatism creates two focal points instead of one, resulting in blurred or double vision at all distances. LASIK smooths out the uneven curvature, bringing all focal points into alignment for clearer, sharper vision, including reduced glare and halos at night.

Types of LASIK 

There is no single “best” type of LASIK. The right procedure depends on your corneal thickness, degree of refractive error, lifestyle, and overall eye health. Here is an overview of the main options available

ReLEx SMILE	Bladeless Femto LASIK	Microkeratome LASIK	Photorefractive Keratectomy	Implantable Collamer Lens
Technology	Femtosecond laser only	Femtosecond laser (flap creation) + Excimer laser (reshaping)	Automated microkeratome blade (flap) + Excimer laser (reshaping)	Excimer laser only	Surgical lens implant (no laser or corneal reshaping)
Correctable Vision Range	Myopia up to –1,000° / Astigmatism up to –500°	Myopia –100° to –1,000° / Astigmatism up to –600°	Myopia up to –1,300° / Astigmatism up to –500°	Myopia up to –500° / Astigmatism up to –200°	Myopia –100° to –1,800° / Astigmatism up to –600°
Recovery Time	1–2 days	1–2 days	1–2 days	1–2 weeks	a few days to 1 week
Incision Size	Very small (~2–4 mm)	Medium (flap ~20 mm arc)	Medium (flap ~20 mm arc)	None (epithelium removed, no incision)	Small (~3 mm)
Advantage	Minimal nerve disruption, less dry eye, bladeless, flapless	High precision flap, no blade, lower complication risk than microkeratome	Widely available, cost-effective, proven track record	Ideal for thin corneas & dry eyes; no flap complications possible	Reversible, suits very high prescriptions, no corneal tissue removed
Limitation	Higher cost; not suitable for very high prescriptions	Higher cost than microkeratome; flap still created	Blade use carries slightly higher flap-related risk	Slower visual recovery; not suitable for high prescriptions	Not a laser procedure; lens implant surgery; higher cost

Advantages and Limitations of LASIK

Like any medical procedure, LASIK comes with both benefits and important considerations to weigh before making a decision.

Advantages of LASIK:

• Provides a permanent correction of refractive vision errors, reducing or eliminating dependence on glasses and contact lenses
• Fast procedure with a quick recovery, most patients see clearly within one to two days
• Performed under topical anaesthetic eye drops, so there is no pain during surgery and no stitches are required
• Day surgery with no overnight hospital stay needed
• Improved quality of life and confidence in daily activities such as sports, travel, and social situations become easier without corrective eyewear
• Reduced risk of accidents caused by poor uncorrected vision

Limitations of LASIK:

• Side effects such as dry eyes, glare, halos, or starbursts can occur, particularly in the weeks following surgery
• The upfront cost is relatively high, as it is typically not covered by standard insurance plans
• Not everyone qualifies — certain eye conditions, pregnancy, breastfeeding, and insufficient corneal thickness can rule out candidacy
• In some cases, vision may gradually regress over time, though this is uncommon and touch-up procedures are possible

Who is qualified to have lasik?

LASIK is not suitable for everyone, and a comprehensive eye evaluation is the only way to confirm candidacy. In general, good candidates for LASIK tend to share the following characteristics

• Stable prescription : Vision should be unchanged, or minimally changed, for at least one year prior to surgery
• Good overall eye health : No active eye infections, diseases such as keratoconus, or history of severe dry eye
• Adequate corneal thickness : Sufficient corneal tissue must exist to safely create a flap and perform the laser correction
• Realistic expectations : Understanding both what LASIK can achieve and the small possibility that glasses may still occasionally be needed
• Age 18 or older : Most clinics prefer patients to be at least 21 to ensure vision stability
• Lifestyle or professional motivation : Those who find glasses or contacts incompatible with their daily activities, career, or sport are ideal candidates

LASIK Procedure

Understanding what happens during LASIK can help ease pre-surgery nerves. The procedure is straightforward and typically takes under 15 minutes per eye.

1. Anaesthetic eye drops are applied : The surgeon places numbing drops in the eye so no pain is felt throughout the procedure. A small instrument holds the eyelids open comfortably.
2. Corneal flap creation : The surgeon creates a thin flap in the outer cornea using either a microkeratome blade (conventional LASIK) or a Femtosecond Laser (Femto LASIK). This flap is gently folded back to expose the underlying corneal tissue.
3. Laser reshaping : An excimer laser, calibrated to your exact prescription measurements, is applied to the corneal tissue beneath the flap. You will be asked to focus on a fixed light during this step, which typically lasts only a few seconds.
4. Flap repositioned : The corneal flap is carefully laid back into its original position, where it adheres naturally without sutures. The eye begins healing immediately.

How to Take Care of Your Eyes After Surgery

Proper post-operative care is essential to achieving the best visual outcome and minimising the risk of complications.

• Rest your eyes in the first 24 hours : Avoid prolonged screen use and rest frequently, especially on the day of surgery
• Wear protective eye shields at night : Use the provided eye covers every night for at least one week to prevent accidentally rubbing your eyes during sleep
• Avoid strenuous exercise for at least 7 days : Sweat entering the eye can cause irritation and increase infection risk
• Wear sunglasses outdoors : Protect your eyes from UV exposure for at least one month after surgery
• Apply prescribed eye drops as directed : This includes antibiotic drops, anti-inflammatory drops, and preservative-free artificial tears to combat dry eye
• Skip eye makeup and skincare around the eyes for approximately one week
• No swimming for at least one month : and avoid deep-sea diving for three months
• Avoid alcohol for at least one week post-surgery
• Attend all follow-up appointments : and contact your doctor immediately if you notice sudden vision changes, increasing pain, or significant eye redness

Conclusion 

LASIK eye surgery is a well-established, effective solution for correcting common refractive vision errors including myopia, hyperopia, and astigmatism. With multiple procedure types available, from Femto LASIK and SMILE Pro to PRK, there is likely an option suited to your eyes, lifestyle, and prescription.

The key to a successful outcome is a thorough pre-operative assessment with a qualified ophthalmologist, a clear understanding of the procedure's benefits and limitations, and diligent post-operative care. For most patients, the reward is life-changing: waking up with clear, unaided vision each morning.

If you are considering LASIK, consult an experienced eye care specialist to determine which type is most appropriate for you.
