In 1950, the Colombia-based Spanish ophthalmologist, Dr. Jose Barraquer developed the first carpenter’s plane-like device called microkeratome.
Microkeratome is used for creating a flap on the cornea for the alteration of refractive errors. This surgical instrument is used precisely to cut the cornea flap during the procedure of LASIK surgery.
During the LASIK procedure, the surgeon first creates a thin corneal flap, opens it, reshapes the cornea with the laser and then repositions the flap over the cornea.
The laser surgery or LASIK seems to be the solution to vision problems, but it is associated with many disadvantages.
The risks or disadvantages associated with LASIK surgery depend on the age, occupation, eye health, etc.
Also, the role of a surgeon should not be underestimated; if a surgeon is skilled and experienced then the percentage of risks decreases.
People over the age of 40 many times require the correction of short sightedness and long sightedness but the surgery can only provide mono-vision correction. So, many times a patient still has to wear glasses for certain activity eg. reading
Furthermore, any kind of surgery failure could result in permanent impairment of vision. Whereas, contact lenses have a much lower risk to correct to the normal 20/20 vision. It can give you instant results as soon as you wear it properly.
To achieve such normal vision you don’t have to spend a large sum of money. The prices of contact lenses are completely affordable and probably could cost less than a regular cup of coffee at Starbucks.
You can also buy different colors of contact lens to enhance your physical look.
Also, the dryness of eyes is another side-effect that is seen common in people who have gone under eye surgery. Such complications are less associated with the contact lens.
If a person finds that the contact lens, which he uses, is causing some complication then he can get a new one. Since, the cost of the lens is affordable, so there is no need to worry for cost of getting new contact lenses.
A person treated with LASIK surgery also has to go for regular check-ups. This check-up is required to ensure that there is no infection in eyes.
With the development of technologies, newer contact lenses are available that ensures more oxygen flow into the eyes. It helps the eyes to stay irritation free and healthy.
