Benefits of LASIK

LASIK is the number one elective surgical procedure today, and more than a million Americans have had the procedure since its inception. The main reason for its popularity is the many benefits that it offers, including minimizing or in some cases even eliminating the need for the patient to use eyeglasses or contact lenses after the procedure.
Let’s take a look at why LASIK is taking the ocular world by storm.
 

Better vision

Clearly, the biggest reason for choosing LASIK is improved vision. While some patients have relatively mild problems with their eyesight, others experience major disturbances in their vision that makes functioning day to day almost impossible without the use of visual aids. LASIK can dramatically improve the quality of your vision, reducing the need to wear visual aids, or in some cases, completely eliminating it.
 

A good investment

Eyesight is also notoriously inconsistent, with the majority of people finding that their vision marginally improves or deteriorates with each visit to their optician. When this happens, it is necessary for the optician to recommend a different prescription, and this means expense as the patient finds themselves purchasing new eyeglasses or contacts to reflect their new visual requirements.

Although there is no guarantee that you will be able to completely prescription-free after LASIK, most patients find that eyesight is so improved that any changes to their prescription are much less frequent. 
Eyeglasses and contacts are known for being fiddly and fragile, and the need for maintenance and replacements are a common complaint. However, with less need for such devices, the cost of caring for them is also reduced. 
 

A short, painless procedure

LASIK surgery can be performed in one, very short procedure. You should expect to spend around 30 minutes in the surgery suite, but the actual time it takes can be as little as 10 minutes – for both eyes! The remainder of the time will be spent preparing you and ensuring you are comfortable afterward. The entire process is carried out after anesthetic drops have been placed into your eyes, so you can rest assured you will feel absolutely no pain throughout. However, if you are particularly anxious about the process, it may be possible to be given a sedative to help you relax.
 

Fast recovery

LASIK eye surgery is renowned for its fast, simple recovery process. You will be able to return home the very same day as your procedure, and the flap that was created in the corneal tissue will start to heal itself without the need for sutures or bandages. Most patients can return to work within a day or two of their procedure. However, you will be expected to attend a follow-up appointment with our Doctors within 48 hours of your surgery so that he can ensure that your eyes are healing correctly.
 

Extremely safe

LASIK is an extremely safe procedure when performed by a certified and experienced eye surgeon. Laser technology means that the incisions are made with total precision and accuracy, and the process is completely sterile. The risk of complications in laser vision correction is very low, occurring in only around 1 in every 10,000 cases.
 

Better quality of life

Eyesight problems can be a huge inconvenience. Activities like swimming and snowboarding are much more difficult if you need to wear glasses or contact lenses. In regular day to day activities, there can be the worry that your eyeglasses may fall off, or that you have left them behind when you need them. If you suffer from pollen allergies, you may find putting contact lenses in nearly impossible. In short, there are lots of ways in which the need for visual aids can interrupt your life, and it can be extremely frustrating. LASIK reduces or removes the inconvenience of eyeglasses or contact lenses and makes it much easier to get on with living life to the fullest.

LASIK (laser-assisted in situ keratomileusis), is the most popular refractive surgical procedure. In this procedure, a laser is used to permanently change the shape of the cornea (the clear covering on the front of the eye) to correct common vision problems such as nearsightedness, farsightedness, astigmatism, and presbyopia. This improves vision and reduces a person's need for glasses or contact lenses.

LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue, giving the cornea a new shape, so that light rays are focused clearly on the retina. In the case of a nearsighted person, the goal of LASIK is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.

LASIK is an outpatient surgical procedure with no need to stay at the surgery center overnight as it will take 10 to 15 minutes to perform for each eye. The procedure is done while the patient is awake, but the patient may request mild sedation. The only anesthetic used is eye drops that numb the surface of the eye. LASIK can be done on one or both eyes during the same session.

How to Prepare for LASIK Eye Surgery?

Before LASIK eye surgery, the eye surgeon will evaluate the patient’s medical history and perform a full eye examination, including measuring corneal thickness, refraction, corneal mapping, eye pressure, and pupil dilation. Afterward, the surgeon will discuss what to expect during and after the procedure.

On the day of the surgery, eat a light meal before going to the doctor and take all prescribed medications, if any. Do not wear eye makeup, creams, perfumes or lotions on the day before and the day of surgery, or have any bulky hair accessories that will interfere with positioning head under the laser.

Contact lenses shouldn't be worn for at least three days prior to the evaluation. In the case of, rigid gas permeable contact lenses, they should not be worn for at least three weeks before. Patients should arrange for a ride home from the place of surgery, as their vision might be blurry.
 

What Happens During LASIK Eye Surgery?

The LASIK surgeon uses a computer to adjust the laser for each patient’s particular prescription. An instrument to hold the eyelids open may be used and the patient will be asked to look at a target light for a short time while the laser sends pulses of light to painlessly reshape the cornea. During LASIK eye surgery, a suction ring is placed on the eye just before cutting the corneal flap that may cause a feeling of pressure and may cause vision to dim slightly. Then, an instrument called a femtosecond laser is used to create a thin flap in the cornea. The corneal flap is then painlessly peeled back and the underlying corneal tissue is reshaped using another laser. After the cornea is reshaped so that it can properly focus light onto the retina, the cornea flap is put back in place and the surgery is complete. A distinct odor might be detected as the laser removes the corneal tissue which some people describe as similar to that of burning hair, but is nothing to worry about.
 

What to Expect After LASIK Eye Surgery?

The eyes might temporarily be dry even though they do not feel that way. One eye drop will be prescribed to prevent infection and inflammation and another eye drop to keep eyes moist. These drops may cause a momentary slight burn or blurring of your vision upon using them. Do not use any eye drops not approved by the LASIK surgeon.

Healing after LASIK eye surgery usually occurs very rapidly. Vision may be blurry and hazy for the first day, but most patients notice improved vision within a few days of surgery. There will be a follow-up evaluation 24 to 48 hours after LASIK eye surgery, as well as at regular intervals within the first six months.
 

What Are the Advantages of LASIK Eye Surgery?

LASIK has many benefits, including:

• Vision is corrected nearly by the day after LASIK.

• LASIK causes a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.

• Adjustments can be made years after LASIK to further correct vision if vision changes with age.

• LASIK is associated with very little pain due to the numbing eye drops that are used.

• No bandages or stitches are required after LASIK.
