Lasik surgery is gaining popularity these days as it is a relatively painless procedure and it also reduces the dependence on glasses and contact lenses. It will not be a surprise if in a few years time we do not see people wearing glasses for eye problems.

High energy laser is used to correct the position of corneal stroma, thereby correcting the vision permanently. Lasik vision institutes are basically centers where a team of experienced and expert ophthalmologists conduct Lasik surgeries for people with eye problems.

Lasik vision institutes advertise in different media like newspapers, television, yellow pages and web sites. The cost of setting up a world class Lasik vision institute can be anywhere between 3-4 crores. But a patient is advised to take in factors like reputation of the Lasik vision institute, association of the Lasik surgeon with academic centers and his experience in handling latest procedures and technology.

However, Lasik is not conducted until the patient crosses teens as the eyes keep changing. Also, there are some risks and post operative complications involved in the procedure. So, these Lasik vision institutes counsel the patient on his eye condition, explains the procedure of Lasik, the benefits and risks involved in the surgery so that the patient can take an informed decision.

There are some pre-operative measures suggested for Lasik surgery. The patient is advised not to wear contact lenses at least fifteen days prior to the surgery as it may alter the shape of the cornea. The procedure takes hardly 30 minutes during which the patient is normally awake and mobile. Anaesthesia is given in the form of eye drops to alleviate the pain.

Lasik vision correction is preferred to PRK, photo refractive keratectomy, as the later takes more time to heal and thereby is more painful. A metal blade called microkeratome is used to create the flap of cornea thereby revealing the stroma. Then, excimer laser is used to vaporize the tissue in a controlled manner thereby remodeling the corneal stroma.

A Lasik surgery may cost anywhere between 25,000-3,50,000. A course of antibiotic and anti-inflammatory eye drops is usually prescribed after the operation. Dark goggles are given to prevent direct exposure to bright light.

However, the Lasik vision correction also has some risks or complications. One of the most common post Lasik complications is Sub-conjunctival haemorrhage, which can be corrected by drugs. Some of the other complications reported frequently are: Sensitivity to light, dry eyes, wrinkles in flap, double vision, debris under flap, erosion of epithelium. But around 92-98% of patients are satisfied with Lasik.

Lasik surgery cost ranges anywhere from $499 to $2,500. The cost of Lasik is based on your surgeonâ??s experience and the type of Lasik surgery performed. There are options when it comes to which Lasik procedure you can choose. Your decision should rest on an appropriate surgical procedure for your eye condition, a trusted Lasik surgeon and a price youâ??re comfortable paying. Understand the different types of Lasik eye surgery and decide which types of Lasik surgery is best for you.

Lasik Background

Lasik is among the most popular forms of laser eye surgery. Lasik eye surgery involves a procedure to permanently reshape the cornea and elicit vision correction. A microkeratome blade is used to create a flap in the thin outer layer of the cornea, called the epithelium. An excimer laser reshapes the cornea, and the flap is replaced. The procedure takes about 15 minutes and the recovery time is fairly fast. Most patients can return to normal activities the next day.

PRK as an Alternative to Lasik Surgery

PRK removes the epithelium with a metal surgical tool. The earliest form of laser eye surgery, PRK typically involves a longer recovery time, allowing for the epithelium to grow back. It can cause more discomfort than Lasik eye surgery. Results often take longer for PRK.

Though PRK involves a longer recovery process, it has been the preferred method for patients with thin corneas and large pupils. However, there are a number of newer variations to the original Lasik eye surgery. Many of these different types of Lasik surgery minimize the risk of original Lasik, and can be performed on patients with thin corneas and other eye conditions.

Lasek Surgery

Lasek is a refractive procedure that uses alcohol to separate the outer layer if the cornea, rather than a surgical blade. A laser reshapes the cornea and the epithelium is replaced. By eliminating the risk of a microkeratome blade, Lasek is an option for people with thin corneas.

Through its swift recovery process, Lasek may be a better alternative to PRK. However, Lasek is not without potential complication. The use of alcohol can cause eye irritation and inflammation.

Epi-Lasik

Epi-Lasik is similar to Lasik and Lasek, but employs a fine surgical blade, reducing the risk of a wide corneal flap. Instead of alcohol, a plastic cutting tool separates the epithelium from the eye. Epi-Lasek thereby eliminates possible irritation to the eye.

IntraLasik

IntraLasik, All-Laser Lasik, or Blade-Free Lasik very simply conducts the procedure through lasers, without the use of a microkeratome. IntraLasik is praised for precision through eliminating mistakes that can occur with a surgical blade.

While IntraLasik significantly lowers the risk associated with other refractive surgery, there are some possible complications to consider. The excimer laser is still subject to possible visual errors. A small percentage of patients have also reported issues with light sensitivity. The cost of IntraLasik can be substantially higher than other forms of Lasik surgery.

Wavefront Lasik

Wavefront Lasik is the most precise form of Lasik eye surgery. Much like IntraLasik, lasers replace blades during Wavefront Lasik. But where IntraLasik employs a freehand excimer laser, wavefront technology guides the excimer laser in Wavefront Lasik. The procedure also reduces the risk of night glare, a common complication associated with Lasik surgery. Though the most accurate, Wavefront Lasik is also the most costly among the different forms of Lasik.
