Wearing spectacles or contact lenses every day can sometimes feel inconvenient, especially while working, travelling, exercising or participating in outdoor activities. If you are exploring ways to reduce your dependence on corrective eyewear, laser vision correction may be an option worth discussing with an eye specialist.
One such procedure is SMILE (Small Incision Lenticule Extraction), a laser-based vision correction technique used to treat certain refractive errors, including myopia (short-sightedness) and selected cases of astigmatism.
Before considering SMILE Surgery in Delhi, it is important to understand how the procedure works, who may be suitable, which tests are required and what to expect during recovery.
1. What Is SMILE Eye Surgery?
SMILE stands for Small Incision Lenticule Extraction. It is a minimally invasive laser vision correction procedure that uses a femtosecond laser to create a small, lens-shaped piece of tissue called a lenticule inside the cornea.
The surgeon removes this lenticule through a small incision. This changes the shape of the cornea and helps correct the refractive error.
Unlike conventional LASIK, SMILE does not involve creating a large corneal flap. However, the choice of procedure depends on individual eye measurements, prescription and clinical findings.
2. Who May Be Suitable for SMILE Surgery?
SMILE surgery is not suitable for everyone. An ophthalmologist evaluates several factors before recommending treatment.
These commonly include:
Age: The patient should meet the recommended age criteria.
Stable Spectacle Power: The prescription should generally remain stable before surgery.
Corneal Thickness: Adequate corneal thickness is important for treatment planning.
Corneal Shape: The cornea should be evaluated for irregularities and conditions such as keratoconus.
Overall Eye Health: Existing eye conditions and ocular surface health must be assessed.
Certain medical conditions, medications, pregnancy or breastfeeding may also influence surgical suitability or timing.
A comprehensive eye examination is necessary before deciding whether SMILE is an appropriate option.
3. Important Tests Before SMILE Surgery
Pre-operative investigations help the surgeon understand your eye condition and assess whether the procedure is suitable.
Some commonly recommended tests include:
Refraction Test: Measures your current spectacle power and identifies the type and degree of refractive error.
Corneal Topography: Creates a detailed map of the corneal surface to identify irregularities in its shape.
Pachymetry: Measures corneal thickness, which is an important consideration during laser vision correction planning.
Tear Film Assessment: Evaluates dry eye symptoms and ocular surface health.
Retinal Examination: Helps assess the back of the eye, particularly in patients with higher degrees of myopia.
Your doctor may recommend additional investigations depending on your medical history and examination findings.
4. How Is the SMILE Procedure Performed?
Understanding the treatment process can help you prepare for your consultation.
The procedure generally involves the following steps:
Eye Preparation: Anaesthetic eye drops are used to minimise discomfort during treatment.
Laser Application: A femtosecond laser creates a small lenticule inside the cornea according to the planned correction.
Lenticule Removal: The surgeon makes a small incision and carefully removes the lenticule.
Post-operative Assessment: Your surgeon examines your eyes and provides instructions for medication, precautions and follow-up visits.
The treatment plan is customised according to your eye measurements and refractive error.
5. What Are the Possible Risks and Side Effects?
Like every surgical procedure, SMILE involves potential risks and side effects. Understanding these is important before making a treatment decision.
Possible side effects include:
Temporary dry eye symptoms.
Glare or halos around lights.
Visual fluctuations during recovery.
Temporary difficulty with night vision.
Undercorrection or overcorrection.
Infection or other surgical complications in some cases.
The likelihood and severity of these effects vary between individuals. Your ophthalmologist should explain your personal risk factors, expected outcomes and available alternatives.
6. What Should You Expect After SMILE Surgery?
Recovery experiences differ from person to person. Some patients resume routine activities relatively quickly, while visual clarity may continue to improve over time.
Following your surgeon's instructions is an important part of post-operative care.
Consider these general precautions:
Use prescribed eye drops as directed.
Avoid rubbing or pressing your eyes.
Attend scheduled follow-up appointments.
Follow medical advice regarding swimming, eye makeup and dusty environments.
Ask your doctor when you can resume driving, exercising and working on screens.
If you experience significant pain, sudden vision changes or worsening symptoms, contact your eye specialist promptly.
7. SMILE vs Other Vision Correction Procedures
SMILE is one of several options available for correcting refractive errors. Depending on your eye condition, your specialist may also discuss:
LASIK: A laser vision correction procedure that involves creating a corneal flap.
PRK: A surface-based laser procedure in which the outer corneal layer is removed before laser treatment.
ICL: An implantable contact lens procedure that may be considered for selected patients who are not suitable for certain corneal laser procedures.
Each option has different eligibility criteria, benefits and limitations. The appropriate choice depends on your prescription, corneal measurements and overall eye health.
8. Questions to Ask Your Eye Specialist Before Booking
Before scheduling SMILE surgery, consider discussing these questions:
Am I suitable for SMILE based on my eye examination?
Is my spectacle prescription stable?
Which pre-operative tests will I need?
What are the possible risks in my case?
Are LASIK, PRK or ICL alternative options?
What precautions should I follow after surgery?
How many follow-up visits will be required?
Having these questions answered can help you understand the procedure and make an informed decision.
