Lasik (laser-assisted in situ keratomileusis) is a type of refractive surgery. This is performed to treat astigmatism, myopia and hyperopia. This process is done through the usage of laser rays. This provides fastest recovery for the patients and is a painless experience. This can be considered as an alternative to glasses and contact lenses.
Dr. Jose Barraquer, a Spanish ophthalmologist was the first one to develop first microkeratome. He experimented with altering shapes of cornea to provide longer results. Modern techniques in radial keratotomy were developed in USSR in 1970s.In 1973, Mani Lal Bhaumik used excimer laser in refractive surgeries thus exposing the utility of laser rays.
Dr. Gholam A. Peyman on June 20, 1989 became the first one to get a patent for a LASIK surgery procedure by the US. After that many attempts had been there and today faster lasers, bigger areas, lap incision techniques, intraoperative pachymetry, etc has improved the style of treatment in a significant way.
Vision correction is the main purpose of Lasik eye surgery. Thus myopia, hyper-metropia or astigmatism etc can be corrected through LASIK eye surgery. It allows people not to wear glasses or lenses to correct these. For people who had worn extremely thick glasses and cylindrical lenses, will feel a lot better through Lasik surgery and can have a better quality of life.
There are different ways to do LASIK eye surgery. Let us look into those.
Wave front Lasik: This is a method in which doctors use a 3d map of cornea and the eye. This is a less risky and better procedure. So many modern era doctors are changing to this particular technique.
Bladeless Lasik: This is a safer practice to correct vision. Here the surgeon uses a special laser to create the flap. The procedure is bladeless and reduces the risk of damages.
Epi Lasik: In this method, the doctor will cut the cornea’s outer epithelium using an oscillating blade made of plastic. It also uses epithelial separator. This method is suitable for people with low visual disturbances.
CK Lasik: Conductive keratoplasty (CK) is a new type of surgery which uses radio waves along with mild heat. It goes through the cornea and is used for people who suffer from presbyopia.
PRK and LASEK techniques are also used according to the situations present. Those with flat corneas will benefit from LASEK method as it loosens epithelium.
Thus LASIK eye surgery is a newer method in the vision correction and has created a revolution in ophthalmology.
