Specs Removal Surgery: LASIK, SMILE, ICL & RLE Explained

Key Takeaways: There are 6 (six) main eye surgeries for specs removal: LASIK, SMILE, SILK, CLEAR, Refractive Lens Exchange (RLE), and Implantable Contact Lens (ICL), each suited to different ages, powers, and corneal conditions. LASIK reshapes the cornea under a thin flap and works well for many people with stable numbers and healthy corneas, offering quick recovery but not ideal for very thin or irregular corneas. SMILE is a flap-less laser procedure using a small incision and internal lenticule removal, causing less dry eye and preserving corneal strength, but it’s mainly for certain myopia/astigmatism ranges. SILK is a newer, lenticule-based and flapless specs-removal procedure where a femtosecond laser creates a thin lenticule inside the cornea and it’s removed through a small incision, this can mean a smaller surface cut and a comfortable early recovery in suitable myopia/astigmatism cases. CLEAR is also a lenticule-extraction (flapless) option done on a specific laser platform, designed to correct myopia with/without astigmatism using a small incision. Refractive Lens Exchange (RLE) removes the natural lens and replaces it with an intraocular lens (IOL), suiting people aged 40–45+ with high powers or presbyopia, and also removes future cataract risk. ICL surgery places a thin lens inside the eye without removing the natural lens, making it a strong option for very high minus powers, thin corneas, or dry eyes where laser procedures are not safe. All these surgeries carry small risks (infection, glare/halos, dry eye, pressure changes, or residual number), so detailed eye scans and counselling are essential before choosing. After any specs removal surgery, careful drop use, no eye rubbing, dust/sun protection, no swimming or eye makeup initially, and regular follow-ups are crucial for smooth healing and stable results. The “best” specs removal surgery is not the same for everyone; it depends on age, eye power, corneal thickness, lifestyle, and expectations, decided together with an experienced ophthalmologist.

If you wear glasses, you’ve probably wondered if an eye operation for removing spectacles could help you see clearly without them.

Today there are several safe, quick specs removal operations that can treat numbers like myopia, hyperopia, astigmatism, and even age-related near-vision issues. 

In this blog, you’ll understand how different types of eye surgery for specs removal work, who they suit, and the questions you should ask your doctor before choosing one.

Different Types of Glass Removal Procedures

Today, there are many options for an eye operation for removing spectacles. The best choice depends on your eye power, cornea shape and thickness, age, lifestyle, and overall eye health. 

Below are 6 commonly advised glass removal surgery options your doctor will discuss with you.

LASIK

LASIK eye surgery is one of the most common laser operations for eyes to remove specs. In this procedure, a thin flap is created on the front of the cornea, and a laser reshapes the underlying tissue to correct your number. 

It is suggested for people with stable power, healthy corneas, and no major eye disease. Variants include femto-LASIK or bladeless LASIK, where a laser instead of a blade is used to create the flap.

Benefits

• Quick procedure; both eyes are treated in the same sitting.
• Vision usually improves within 24–48 hours.
• Minimal discomfort and fast recovery, so you can get back to work quickly.
• Suitable for many types of refractive errors (myopia, hyperopia, astigmatism).

Drawbacks

• Not suitable if the cornea is very thin, irregular, or if numbers are unstable.
• Risk of dry eyes, glare, halos, or night-vision difficulties in some patients.
• Corneal flap is permanent; although rare, trauma can disturb it later.
• Not always the best eye surgery for specs removal in very high powers.

Procedure

• Numbing drops are placed in your eyes.
• A flap is created on the cornea using a microkeratome or femtosecond laser.
• An excimer laser reshapes the underlying corneal tissue to match your eye number.
• The flap is gently placed back in position and sticks naturally without stitches.

SMILE: Small Incision Lenticule Extraction (SMILE)

SMILE is a newer type of glass removal surgery that uses a femtosecond laser to create a thin lens-shaped piece of tissue (lenticule) inside the cornea. This lenticule is then removed through a very small cut, which changes the cornea’s shape and corrects your power. 

There is no flap, which helps maintain corneal strength and reduce dry eye symptoms in some patients.

Benefits

• No large flap; only a small keyhole-like incision.
• Causes less dry eye in many patients compared to traditional LASIK.
• Good option for certain ranges of myopia and astigmatism.
• Fast recovery with relatively little discomfort.

Drawbacks

• Not suitable for all eye powers and all types of refractive errors (for example, hyperopia is not usually treated with SMILE).
• Fewer enhancement options compared to LASIK if some power remains.
• Availability can be limited to selected centres with specific laser platforms.

Procedure

• Detailed scans of the cornea are done before surgery.
• During the procedure, a femtosecond laser creates a lenticule inside the cornea.
• The surgeon removes this lenticule through a small incision on the cornea.
• The cornea reshapes itself once the tissue is removed, improving your vision.

SILK (Smooth Incision Lenticule Keratomileusis)

SILK is a lenticule-based, flapless laser vision correction procedure. Like SMILE, a femtosecond laser creates a thin, lens-shaped tissue (lenticule) inside the cornea, and the surgeon removes it through a small incision to correct the eye number (mainly myopia, with or without astigmatism).

Benefits

• No large corneal flap, so the cornea’s front layers are less disturbed compared to flap-based LASIK.
• Small incision approach, which may be more comfortable for many patients during early healing.
• Lenticule-based technique that aims to preserve corneal strength and can be a good option in suitable myopia/astigmatism ranges.

Drawbacks

• Not for everyone, eligibility depends on corneal scans, stable power, and suitability for the platform being used.
• Availability varies because SILK is done on specific laser systems and may be offered only at select centres.
• Enhancement planning can differ from LASIK; if a small residual number remains, your surgeon will guide the safest next step.

Procedure

• Detailed pre-op scans are done to confirm corneal thickness, shape, and number stability.
• A femtosecond laser creates a lenticule inside the cornea and makes a small access incision.
• The surgeon gently removes the lenticule through that incision.
• Once the lenticule is removed, the cornea reshapes and vision improves gradually as the surface settles.

CLEAR (Corneal Lenticule Extraction for Advanced Refractive Correction)

CLEAR is also a lenticule-based, flapless procedure. The laser forms a lenticule within the cornea and the surgeon removes it through a small incision, reshaping the cornea to correct myopia and astigmatism in suitable patients.

CLEAR is performed using the Ziemer FEMTO Z8 platform.

Benefits

• Flapless technique, so the upper corneal layers are minimally disturbed.
• Less impact on corneal nerves in principle, which can potentially reduce dry-eye issues in some patients compared to flap-based options.
• Uses a single femtosecond laser to create and assist lenticule extraction, with controlled centration/alignment features described in published studies.

Drawbacks

• Eligibility is scan-driven, thin/irregular corneas, unstable power, or other eye issues may rule it out.
• Not ideal for every prescription type; surgeons decide based on refractive error, corneal shape, and lifestyle needs.
• Like other lenticule procedures, enhancement options may be different from LASIK, so planning needs a proper discussion.

Procedure

• The eye is mapped with scans to confirm suitability and plan treatment.
• The femtosecond laser creates a lenticule inside the cornea and a small access incision.
• The surgeon extracts the lenticule through the small incision to change corneal shape and correct the number.
• Healing is stitch-free, and vision improves as the cornea stabilises over the next days to weeks.

Implantable contact lens (ICL)

Implantable contact lens (ICL) surgery is a specs removal operation where a very thin, customised lens is placed inside the eye, in front of your natural lens. 

Unlike RLE, the natural lens is not removed. ICL is recommended for people with very high minus power or those who have thin corneas or dry eyes and are not good candidates for LASIK or SMILE.

Benefits

• Good choice for high myopia or astigmatism, where laser options may not be safe.
• Cornea structure is largely preserved because no tissue is removed.
• Vision quality can be very sharp and clear in suitable patients.
• The lens can be removed or exchanged if needed in future.

Drawbacks

• It is an internal eye operation for removing spectacles, so it has risks like infection, raised eye pressure, or cataract over time.
• Requires careful sizing and planning; regular follow-ups are important.
• Not suitable for everyone; needs good front-chamber depth and healthy eyes.

Procedure

• Measurements are taken to decide the exact size and power of the implantable lens.
• On the day of surgery, the eye is numbed with drops, and a tiny opening is made.
• The folded ICL is inserted and gently positioned in front of the natural lens.
• The tiny wound usually seals on its own; you go home with eye drops and follow-up advice.

Refractive lens exchange (RLE):

Refractive lens exchange is a type of eye surgery for specs removal where your natural lens is removed and replaced with an artificial lens (intraocular lens or IOL). It is very similar to modern cataract surgery, but here the main goal is freedom from glasses and clearer vision at different distances. 

RLE is usually suggested for people above 40–45 years, especially when reading glasses have started, or when laser surgery is not ideal because of high power or other eye conditions. The doctor can choose from different types of IOLs, such as monofocal, multifocal, or toric lenses, based on your needs and lifestyle.

Benefits

• Helps reduce or remove dependence on distance and reading glasses.
• Good option when power is very high or cornea is thin or irregular.
• Can correct astigmatism with toric IOLs.
• Future risk of cataract is essentially removed because the natural lens is replaced.

Drawbacks

• Invasive surgery to remove specs, done inside the eye.
• Small risk of infection, swelling, glare, or halos at night.
• Multifocal IOLs need some time for the brain to adapt to new vision.
• Usually not advised for very young patients with healthy natural lenses.

Procedure 

• The eye is numbed with anaesthetic drops and sometimes a small injection.
• The natural lens is broken into tiny pieces and gently removed through a small cut.
• A foldable artificial lens (monofocal, multifocal, or toric) is inserted in its place.
• No stitches are usually needed; you go home the same day with eye drops and follow-up instructions.

What to do after a Specs Removal Operation?

After any eye operation for removing spectacles, caring for your eyes properly is just as important as the operation itself. Mild blurring, light sensitivity, and a gritty feeling are common in the first few days after a specs removal operation. 

These improve as the eye heals, but if you feel sudden pain, a sharp drop in vision, or see flashes and floaters, you should contact your eye doctor immediately. Your doctor will give you specific instructions based on the procedure you had, but some general tips apply to almost everyone:

• Use the prescribed eye drops exactly as advised, and do not stop them on your own
• Avoid rubbing or pressing your eyes, even if they feel itchy or watery.
• Limit screens, reading, and close work in the first few days if your doctor suggests it.
• Wear the protective shield or dark glasses given to you, especially while sleeping or going out.
• Stay out of dust, smoke, and strong sunlight; use sunglasses when you are outdoors.
• Avoid swimming pools, eye makeup, and heavy exercise until your doctor says it is safe.
• Do not drive until your vision is clear and your doctor has cleared you.
• Attend all follow-up visits so your doctor can check healing and measure your vision.

Conclusion

Modern eye operation for removing spectacles offers many safe and effective ways to reduce or even remove your dependence on glasses and contact lenses. 

Options like LASIK, SMILE, SILK, CLEAR, Refractive Lens Exchange (RLE), and Implantable Contact Lens (ICL), each have their own benefits, risks, and ideal patient profiles. 

The best eye surgery for specs removal is the one that matches your eye health, power, age, and expectations, after a detailed discussion with your ophthalmologist. A thorough check-up and honest conversation with your doctor will help you choose wisely and enjoy clearer, more comfortable vision in the long run.

FAQs

Is there any surgery to remove spectacles?
Yes, there are 6 surgeries to remove spectacles such as LASIK, SMILE, SILK, CLEAR, Refractive Lens Exchange (RLE), and Implantable Contact Lens (ICL). They can reduce or remove your need for glasses or contact lenses, depending on your eye condition.

Is specs removal surgery painful?
No, specs removal surgery is not painful because numbing drops are used; you may feel mild pressure during the procedure and some scratchy sensation, watering, or light sensitivity for a short time afterwards, which settles with drops and rest.

Can I remove my spectacles permanently without surgery?
No, you cannot remove spectacles permanently without surgery. Lifestyle changes or eye exercises cannot reliably correct refractive errors; to reduce or remove your number in a lasting way, you need some form of surgery to remove specs.

What is the best age for specs removal surgery?
The best age for specs removal surgery is after 18 years, once your eye power has been stable for at least 1–2 years. 

For some procedures like refractive lens exchange, doctors prefer patients who are in their 40s or older, so the “best” age depends on the type of surgery and your eye health.

How much does specs removal surgery cost in India?
Specs removal surgery cost in India can vary widely depending on the type of glass removal surgery, city, hospital, technology used, and the surgeon’s expertise.
