What Is Lasik And Importance Of Lasik DoctorsWho are lasik doctors Lasik doctors are the doctors performing surgical operations using lasik treatment. It is the most popular and a very well recognized surgery in the US. Lasik doctors carry out this treatment by changing the shape of the cornea resulting into a lesser use of glasses or contact lenses. Before starting the surgery lasik doctors discusses with the patient about his condition and to what extent the problem will be solved. This discussion by the lasik doctor with the patient is important as there are certain cases where the even after the surgery the glasses are not fully removed. This usually happens in the cases of those patients whose thickness of the cornea is less. Lasik doctors are mostly called for this surgery for getting relief from glasses and corrective lenses. What is lasik Lasik is a surgery conducted by Lasik doctors for the removal of lenses or glasses from the eye. This surgery is done by changing the shape of the cornea. Lasik stands for Laser-Assisted in Situ Keratomileusis. It is one of the types of refractive laser eye surgery. It is done by Ophthalmologists. The various defects for which the lasik eye surgery is done by lasik doctors are myopia, hyperopia and astigmatism. It is generally used by patients as an alternative for wearing glasses or lenses. Lasik is a combination of Photorefractive Keratectomy (PRK) and Automated Lamellar Keratoplasty (ALK).A Lasik flap is counted in both its weakness and strengths. Lasik is a surgery which can be treated with both types of ablation, conventional ablation and wavefront guided ablation. However, there are cases where PRK/ASA is preferred to lasik. How lasik works The main tool used to operate eyes during a lasik operation is light. The shape of a human eye is in the form of a ball, so when light fall on it, it gets refracted and focuses on the retina. Its working is almost like that of a camera which directs light into it to fall onto the film inside it. So the image on which light falls appears as a small image on the retina. Then starts the functioning of the optic nerve, a large nerve which is situated at the back of each eye. From the optic nerve the information of the image is transmitted to the brain, which then interprets the same and tells us the details of the image. However, there are some cases where the interpretation of the image is not done properly and we result in understanding the wrong message. This happens when the cornea is not properly round, and here comes the role of Lasik doctors who with the help of lasik surgery rectify the shape of the cornea. The light rays used in the lasik surgery are ultraviolet beams, also known as excimer lasers. Many Lasik doctors also use intralase laser for the creation of the lasik flap. The difference in intralase laser and traditional laser lies in the creation of the corneal cap. The lasik surgery done by intralasik laser is more precise and blade free. It also helps to prevent the formation of buttonhole flaps inside the eye which can be a reason for creating scars and can thereby affect the vision. |
