Since the beginning of time, people have been concerned about vision. Glasses and contact lenses were the only options before LASIK emerged. And probably, eyeglasses and contact lenses provided people with temporary improvement in vision. But there was still a need for permanent solution.
LASIK was one of the first successful refractive surgeries invented in the 1990s. It changed the way of correcting the vision with excimer laser. It was probably the first highly effective process with fewer side effects that provided a permanent relief solution to vision problems. It can be used for treating near-sightedness, farsightedness, and astigmatism.
In the 19th century, laser procedures were met with partial success with problems in some. It was due to the minimal understanding, less experience, limited availability of skilled surgeons, and advancement in technology. Then came excimer laser in the 1970’s. It was found to have the ability to cut through organic tissue with incredible precision. And in 1971, the very first successful surgery was performed, known as photo refractive keratectomy. In this Excimer laser was used to reshape the cornea. It lead to rapid growth of the use of excimer laser in the field of "Ophthalmology".
In 1991s, an excimer laser was paired with a new device called Microkeratome. A microkeratome is a surgical instrument used to make a précise cut in the corneal flap. It allows the excimer laser to reshape the corneal stroma. This flap is later put back and heals naturally. This new process was called LASIK (Laser-Assisted in-situ Keratomileusis). After successful trials, LASIK received approval from FDA in 1999.
Even though other vision surgical options are available, LASIK remains the first and popular choice for many people. Some of the reasons why patients prefer LASIK are:
LASIK is permanent and once the cornea is reshaped, it will maintain its shape for years. The results are so good that most people do not need further treatment. Only 1% of patients go for second/enhancement surgery. LASIK is your investment in your vision and future happiness.
