Lasik – The Advancement Of Eye Treatments In Last Two Decades
In the beginning, there was Radial Keratotomy (RK), a type of surgery performed in the USA during the 80s. It involved cutting incisions in the surface of the eye to correct nearsightedness. This was a crude method to deal eye issues, and it spawned some long term problems to the patients. Those issues weren’t significant in patients that received a lower prescription, but they did pose a problem to those that had to go through extensive treatments.
PRK aka Photorefractive Keratectomy was the treatment that succeeded the RK, and it came to be known as the first eye surgery that uses lasers as tools for treatment. This procedure involves correction of the vision by removing tissue that allows the change in the curvature of the cornea. This procedure has been in use for over three decades, and some entities still use it. It is still a viable way to address issues with eyes, but the LASIK treatment is more popular, and according to some better than the PRK.
What is LASIK and how it works
LASIK, or Laser-assisted in situ keratomileusis, is an eye surgery procedure that uses lasers to correct issues that plague eyes. It can reshape the cornea and get rid of some pretty serious medical conditions like hyperopia, astigmatism, and myopia. This is a fast and safe procedure as it won’t cause any pain or discomfort and it will be done within ten or fifteen minutes. You might not be a good candidate for LASIK, and thus your doctor will give you other options that will work quite well.
This procedure is quite straightforward. The surgeon will open your eye with a microkeratome and create a flap in the cornea with a laser. The said laser will reshape the cornea and allow it to focus the light better and thus improve the vision. Which part of the cornea will it reshape depends on the medical condition you have.
The advanced form of the LASIK
The standard form of the Lasik has its limitations, and they can make it impossible for you to receive the treatment you need. Those restrictions are reasonable, and it’s easy to see why you can’t get what you want. But this changed in last year or two with the introduction of ilasik. The launch of this eye treatment changed the world of eye surgery. It removed the need to check whether a patient is eligible for the operation and that was an enormous change in this field.
The treatment is adapted to the patient, and thus anyone can undergo it. The software that accompanies the laser will scan the eye. And mark the incisions that will correct the medical eye condition in question. The computer is capable of completing the surgery on its own, without any input from the medical operator. The surgeon still needs to oversee the process and jump in if they determine that the computer isn’t doing everything that is required. The system has several locks that make sure that no critical mistake harms the patient.
