Lasik Surgery


What is Lasik Surgery?

Laser-Assisted In-Situ Keratomileusis

Laser eye treatment as an option for eye power correction has been in vogue for over two decades now. The first laser vision correction was performed in Germany in the late 80s, and since then, there’ve been major advancements that have improved the quality of the surgery in terms of safety and precision. While laser eye treatment is primarily used for correcting refractive errors, laser technology has been put to good use in cataract and retinal treatments as well.

Laser Vision Correction – Get rid of your glasses

Laser vision correction is by far the best option to eliminate the dependency on glasses and contact lenses. The shape of your cornea attributes to your eye power. You could have myopia (short-sight), hypermetropia (long-sight) or astigmatism (blurry vision) depending on the point where the light from an object you see gets focussed inside your eyes.

During a laser vision correction surgery, the shape of your cornea is altered in such a way that light entering into the eye is focused at the right spot on the retina. This is a simple procedure and takes less than half an hour from start to finish. Also, you’ll be able to resume your normal life in just a few days.

Laser Vision Correction – Options

Laser vision correction has evolved rapidly over the last twenty years. LASIK is the most popular refractive error correction surgery and can rectify a power of -1D to -9D in myopia patients and up to +4D in hypermetropia patients.

In LASIK, a motorized blade is used to create a flap of the first two layers of the cornea, and a computer-controlled laser is used to reshape the inner layers. Intralase is a blade-free approach where a specialized laser is used to create this flap and then reshape it. ReLEx SMILE has come in as the next advancement and is bladeless and flapless with much faster recovery.

Does laser eye treatment or vision correction last a lifetime?

While the effects of a laser eye treatment (LASIK treatment surgery) are permanent, the benefits can decrease over time. However, for most patients, the results of LASIK surgery will last forever. 

It is advisable to avoid undergoing the LASIK eye surgery procedure for patients on systemic medicines, preventing the complete recovery of the cornea. Other reasons for not performing laser eye operations on patients are systemic conditions. These are the diseases like diabetes or conditions wherein the collagen level in the body is not normal, for example, the Marfan syndrome. Also, if a patient cannot stare at a fixed object for a minimum of 60 seconds, the patient may not be a great candidate for LASIK eye surgery. 

If you go for a LASIK surgery procedure, the doctor will require an initial baseline evaluation to determine if you are a suitable candidate for the laser eye operation.

It can take up to 6 months to completely recover from a laser eye operation. In this phase, you may need to visit your doctor for several aftercare appointments. There might also be blurriness in certain stages, but it’s normal.

In addition, it will take some amount of time for the eyes to settle post-surgery. Therefore, you must attend the aftercare appointments regularly to maintain the lifetime guarantee validity. 

Blurred vision is common up to 6 months after the LASIK eye treatment, mainly because of the dryness of the eyes. It is best advised to use artificial tears at least once every hour and rest the eyes frequently to avoid dryness. 

There is no age limit for LASIK, and the surgery depends on the eye health of the individual, in addition to the visual needs. Patients with no organic reason for vision loss, such as cataracts or other medical complications, can easily go for a LASIK surgery. 

Immediately after LASIK treatment, the eyes may itch or burn or feel like something is stuck in the eye. There can be a certain level of discomfort and mild pain in some cases. The doctor may suggest a mild pain-relieving medicine for the same. The vision can be blurred or hazy. 

Instilling numbing eye drops helps with the urge to blink in the patients during the laser eye treatment. A device is also used to keep the eyes open in times of need during the surgery

LASIK eye operation is not painful. Before starting the procedure, the surgeon will use numbing eyedrops for both your eyes. While there might be a feeling of pressure during the ongoing procedure, there will be no feeling of pain. 

Laser eye operation for cataracts is a viable option since it helps rectify the refractive errors by reshaping the cornea using a laser. However, in cataract cases, LASIK will not correct the blurred vision caused by this disorder. 

Some people have a blurred vision right from birth due to some congenital disabilities, while others have developed a blurred vision with time. In some cases, blurry vision can be rectified with the help of LASIK eye treatment or surgery. 

In this type of procedure, the tissues of the corneal surface are removed from the corneal surface (front part of the eye), which helps maintain the effects for a lifetime and are, therefore, permanent. The surgery helps with the correction of refractive error and clarity of vision.

Contrary to public notion, LASIK is not a very costly treatment. It is imperative to keep in mind that laser eye surgery price can vary due to different factors like infrastructure, technology, equipment, ranging from Rs. 25000 to Rs. 100000.
