Benefits and Advantages of ReLEx SMILE Surgery

ReLEx SMILE surgery is one of the most widely performed surgeries in the world and is used to treat myopia and astigmatism. SMILE stands for Small incision lenticule extraction and earlier, it was known as Femtosecond lenticule extraction (FLEx). The entire method was developed by Carl Zeiss Meditec. ReLEx SMILE surgery has myriads of benefits when compared to traditional eye surgery and involves lesser precautions and is more accurate.

What is ReLEx SMILE Surgery?

The surgery is performed by an eye specialist or an ophthalmologist. ReLEx SMILE surgery is an advanced type of minimally invasive surgery which is bladeless, painless, and stitchless. It is a great alternative to eye traditional surgery methods such as LASEK and LASIK treatment.

In ReLEx SMILE surgery, a top-notch Carl Zeiss VisuMax laser is used which places a series of pulses in the center of the cornea which is affected. The accuracy level is very high in this type of surgery because it utilizes 3D mapping. These pulses form minute bubbles that have a 1/100th width of human hair and are used to outline the tissues that need to be removed because of deterioration. After this, the laser creates a minute tunnel which is used to draw out the damaged tissue.

This treatment demands no flaps and the whole procedure requires only few seconds for completion. The best part of this procedure is that 80% vision is restored within minutes. And after a few days, the patient’s vision will be magnificent and reaches normal level within a few days of time.

Benefits of ReLEx Smile surgery

Because laser is involved in this treatment, ReLEx SMILE is great in terms of accuracy. In this method, there is no chance of the flap moving, shifting, dislocating or folding and the chances of having dry eyes is negligible. Also, the procedure is considered to be a better alternative for the long-term stability of the cornea. The entire process takes place in a closed room and there is no chance for the involvement of external factors like – temperature, draft, dust or humidity.

  1. Flapless Method: ReLEx SMILE surgery has changed the way of refractive surgery is performed. Earlier, an eye specialist has to make a side-cut of approximately 28 mm. But now, a small incision which is lesser than 2 mm is sufficient enough to perform ReLEx SMILE which makes it a micro-incision keyhole procedure.
  2. 100% Femto: ReLEx SMILE surgery is a hi-tech method which utilizes Femtosecond laser for maximum accuracy. In this method of treatment, high-precision ZEISS VisuMax laser is used.
  3. Single-step procedure: ReLEx SMILE brings a lot of factors together which make the process easier to perform and more successful – the complete laser treatment and lenticule access and creation both take place in a single step.
  4. Indication range: ReLEx for myopia and astigmatism

Sphere: -0.50 to -10.00 D

Cylinder: 0 to 5.00 D

Spherical equivalent: -0.75 to -10.00 D

Comparison of ReLEx SMILE and LASIK Surgery

LASIK stands for laser in-situ keratomileusis. This is highly popular surgery and LASIK is used to treat vision problems in people who are suffering from farsightedness, nearsightedness or astigmatism. The procedure works by reshaping the cornea which is present in the front side of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye.

  • In a survey of 1000 patients, 82% of patients said SMILE is better, faster, and safer than LASIK treatment.
  • LASIK is a method where there is a need to create a FLAP and on the other hand, ReLEx SMILE is entirely a flapless procedure.
  • In ReLEx SMILE, an eye specialist uses only one laser during the procedure and that’s – Zeiss Femtosecond laser. In LASIK treatment, an ophthalmologist uses different brands of excimer lasers to treat eye problems.
  • Recovery time of the SMILE procedure is quicker than LASIK treatment.
  • Research suggests there may be less risk of dry eyes after SMILE, compared with after LASIK.

When it comes to overall advantage, ReLEx SMILE wins over LASIK over a big margin. The entire process is bladeless, flapless, painless, and stitchless. Also, the procedure is highly advanced which uses only Femtosecond laser for better accuracy. The patient does not suffer from dry eyes after the treatment in ReLEx SMILE.

Difference Between ReLEx SMILE & LASIK Laser Procedure

ReLEx SMILE and LASIK are the two most commonly used surgeries in the world that are used to treat myopia, hyperopia, and astigmatism. Both procedures are painless and bladeless and involve the utilization of lasers for gaining better accuracy and fewer complications.  A survey shows us that almost 92-98% of eye patients are happy with the post-surgery results of ReLEx SMILE. In extremely rare cases of LASIK, the patients have to still continue wearing glasses or contact lenses post-surgery because their eye condition is either over- or under-corrected.

What is LASIK laser surgery?

LASIK stands for Laser-Assisted in Situ Keratomileusis and is one of the most commonly performed eye surgeries in the world. The treatment is used to cure myopia, hyperopia, and astigmatism. It is a laser refractive surgery that is used to reform the front part (cornea) of the eye which enables the light to enter and pass through it without the involvement of glasses or contact lenses. LASIK is also a painless method and demands only 15-20 minutes max. to treat both the eyes. A patient can feel the difference soon and vision improvement is imminent and the whole procedure needs only 24 hours to stabilize.

What is ReLEx SMILE?

ReLEx SMILE surgery is one of the most popular and widely used surgeries in the world which is used to cure myopia and astigmatism. SMILE stands for Small incision lenticule extraction and previously, it was known as Femtosecond lenticule extraction (FLEx). The method was pioneered by Carl Zeiss Meditec and the entire process is painless, bladeless, and stitchless. It is at par excellence with traditional eye surgery which utilizes hand-held tools like diamond blades. ReLEx SMILE uses advanced Femtosecond laser for 3D mapping and the process is more accurate and encompasses fewer precautions than the traditional one.

Difference between ReLEx SMILE and LASIK

LASIK requires Flap and ReLEx SMILE is Flapless: In LASIK, an eye surgeon makes a corneal flap with the help of an instrument called microkeratome or with Femtosecond laser. Why flap is required in LASIK? It is because to treat myopia or astigmatism, the eye specialist cannot treat the eyes in its first layer of the cornea because it is very sensitive to external factors. Even a single dust particle is dropped on the 1st layer of cornea, you will feel a burning sensation. They have to go deeper and operate in the internal layers.

With ReLEx SMILE, there is no cut or flap required for the treatment and this treatment method is chosen by those patients who have a fear of having a “cut” in their eyes. The Femtosecond laser makes a small “lenticule”, which is used to treat eye conditions.

Different types of laser used: ReLEx SMILE surgery utilizes a Femtosecond laser developed by Carl Zeiss Meditec and is super accurate for making 3D mapping of the affected eye. On the other hand, LASIK uses Femtosecond laser or different types of excimer lasers.

Different recovery time: The recovery time for ReLEx SMILE surgery is lesser than LASIK because no cut or flap is made during ReLEx SMILE. The total recovery time for ReLEx SMILE is 2-3 hours and the total recovery time for LASIK is 15-30 days. A patient treated with ReLEx can resume their work within a week but the same is not possible for LASIK.

Taking part in outdoor activities: A patient who has been treated with ReLEx SMILE can take part in activities such as cycling, swimming, and exercise just after 2 days post-surgery. But a patient, who has been treated with LASIK will require at least 30 days for taking part in exercises and outdoor activities.

The cost incurred: There is a difference between the cost of LASIK and ReLEx SMILE based on the technology and procedure used in the treatment. Also, it depends upon center to center and the type of laser and accessories used.

So, we came to know that ReLEx SMILE surgery is better than LASIK because ReLEx doesn’t involve any flaps to be made during the surgery and also, ReLEx SMILE procedure’s recovery time is lesser than that of LASIK. A LASIK-patient can take part in outdoor activities after a month, but a ReLEx-patient can resume their work within 2 days, max. The good thing about LASIK is that it is comparatively cheaper than the ReLEx SMILE procedure.

Dada Laser Eye Institute is one of the best eye clinics in India and here, we treat patients with LASIK and ReLEx SMILE according to their choice or preference. Dr, Jeevan Ladi has 25+ years of experience as an ophthalmologist and has been awarded a Gold Medal for his extensive work in laser eye surgery.

Laser Eye Surgery Aftercare

Aftercare is positively recommended and is a pivotal step in your laser eye surgery treatment. Post-surgery, your eyes are susceptible to light and they become very sensitive. Protecting your eyes is very critical to ensure you reduce the risks of any possible complications and see the best possible results. The aftercare procedures also differ from person to person, such as, for someone, it might take 2 days and for some it might take up to 5 days.

Laser Eye Surgery Recovery Tips & Advice

1. Initial Aftercare
After your treatment, you will be advised to stay in the eye clinic or hospital, until you feel comfortable to make your way back home.During this time period, your eyes are recuperating and getting its strength back. For your information, driving immediately after the surgery must be avoided at all costs. So, you have to organize for your personal transport services or ask a family member or a friend to help you get home.

2. Aftercare During The First 2 Days
You must avoid taking a shower immediately after surgery because there is a small chance that it might hinder your progress in vision. For better results, avoid taking shower for at least 1-2 days post-surgery. It is also advisable that you must not resume your work for 1-2 days after the treatment, following a LASIK, ReLEx SMILE or LASEK. No matter where you work, your eyes will be exposed to different types of strain, so if you do need to venture outside try to stay close to home, just in case you feel any discomfort.

During the initial days of aftercare, you might be asked to attend a follow-up exam where an ophthalmologist will examine your eye health and provide feedback along with any medications if required. On average, most patients will be back on the road within the first few days. However, it is always recommended to wait for few days before exposing your eyes to computer or smart phone screen because they emit nonionizing radiation.

3. Aftercare During the First Week
During the first seven days, it is important that you must reduce the chances of exposing your eyes to irritation. It is recommended to not put any makeup around your eyes and keep your eyes away from any soap products. Also, avoid going to such places that have a lot of smoke and stay away from people who smoke. Don’t rub your eyes during the first week of aftercare because it might create complications.

After 3 days, your eyes will have recovered enough and you can start exercising such as a morning cycle ride or jogging on a treadmill. It is preferable to wait for a week before continuing aerobic exercises or practicing Yoga. If you weightlift, wait for at least two weeks before resuming your exercise routine because weightlifting cause muscle strain including your eyes.

4. Aftercare After a Month
After a month, your eyes will have gained enough strength and you can enjoy sports activities like tennis, swimming, football, snowboarding, and cricket. It is highly advised to stay away from any kind of steam room and sauna for at least a month. If you have an itinerary or you are going for a vacation soon after your laser eye surgery, wait for at least 10 days. When you wait for more, you are actually reducing the risk of any possible complications.

What is The Typical Recovery Time for Laser Eye Surgery?

The recovery time is different for different types of procedures. For example, LASEK requires 5-7 days of recovery time and ReLEx Smile / LASIK has a very quick recovery and takes only 2 days before you can resume your work.

What Should I Expect for Recovery?

Some people might experience improved vision immediately after the surgery, but it is quite common that the patient might feel blurry vision for at least a day or two. You will not have many restrictions during recovery time, but it is very important not to lift any heavy objects or engage in strenuous exercise for one week.

So, now you know everything about laser eye surgery aftercare. Try to take rest for a week or so and do not engage in any activities that cause stress on your eyes. Over time, you will again experience the vision you were looking forward to.

Know All About Bladeless Laser Eye Surgery

Many people suffer from various types of eye disease like glaucoma and cataract. Most of the eye patients go to an eye clinic for treatment where an ophthalmologist or an eye specialist take care of their eyes. For cataract, an ophthalmologist will ask you to undergo an operation which might be traditional, or laser-based. Bladeless laser cataract surgery is better than the traditional one because it is accomplished via laser which is very accurate, and the entire procedure is painless and stitchless.

What is Bladeless Laser Cataract Surgery?

If you want that an eye specialist performs an operation with your eyes but you’re afraid of pain, blades or stitches then laser surgery is definitely for you. In bladeless LASIK or Femto LASIK, the surgeon will use two types of lasers for the vision correction procedure. First, an ultra-fast femtosecond laser is utilized to make a thin flap in the cornea which is the clear front surface of your eyes.

Next, an excimer laser will be used to reshape the underlying corneal tissue to treat and correct your vision. After this, the flap will be returned to its original position. The femtosecond laser will eliminate the requirement for a bladed surgical tool which is known as the microkeratome to create the corneal flap in eyes. So, now you know that no surgical blade of any type is needed in all-laser or Femto LASIK.

Advantages of Bladeless Laser Cataract Surgery

1. Safer Procedure: Femto laser surgery is safer than the traditional oneas there is no chance of any possible human error. The incisions are controlled by laser and are super accurate in terms of depth and architecture.

2. No Cell Damage: A survey shows that not even a single endothelial cell is damaged during the Femto laser cataract surgery. This is good news because endothelial cells are also known as the barometer of our eye health and they preserve the clarity of cornea and they are non-regenerative in nature.

3. Precision Mapping: Beforehand Femto surgery, the laser system permits an ophthalmologist to make a 3D mapping of your eyes which helps in achieving highly precise results.

4. US-FDA Approved: Femto laser surgery is 100% US-FDA approved which shows its credibility. After receiving the accreditation, such laser surgery systems are also made available in India.

5. Improved Vision: Conventional Phaco only addresses the existing cataract problem and it doesn’t have any impact on pre-existing astigmatism. Why? It is due to the abnormal corneal curvature. But on the other hand, Femto laser also corrects the pre-existing cylinder in a patient’s eye, with the help of astigmatic correction module there by resulting in a better outcome as compared to conventional Phaco.

How is Femtosecond Bladeless Cataract Surgery Different from Conventional Phacoemulsification Surgery?

During conventional phacoemulsification surgery, an eye specialist will make the incision in the cornea with the help of a metallic blade.They also have to manually create an opening in front of the lens capsule to avail access into the cataract affected area which is achieved via a handheld ultrasonic probe. In bladeless cataract surgery, the Femtosecond laser is used to create incisions, make openings into the lens capsule, and divide the lens into fragments. Henceforth, the minute fragments are removed with the help of ultrasonic probe. In the end an intraocular lens is placed inside the eye to replace the natural lens that was removed.
