LASIK or Laser-Assisted In Situ Keratomileusis, commonly known as laser vision correction or lasik, is a kind of refractive keratectomy for the treatment of myopia, hyperopic, and astigmatism by means of a laser. It is designed for those who have experienced a refractive error such as nearsightedness, farsightedness, astigmatism, or presbyopia. The procedure can also correct other myopia conditions like cataract and retina conditions.
A cataract is one of the most common vision conditions that lasik surgery may correct. Cataracts can cause severe visual distortions especially at night time and when looking straight at nearby objects. The procedure enables the surgeon to remove the excess fluid from the affected area, relax the muscle around the eyes, and then reshape the lens by cutting the corneal tissue. This will result in clearer and sharper eyes which are free of cloudy or hazy eyes. Because of cataract and its effects on the eyes, people who have cataracts should avoid bright lights at all times and always wear sunglasses, even during daytime.
Another condition that lasik surgery may correct is the condition called myopia or nearsightedness. This occurs when you cannot correctly focus on nearby objects. The procedure helps to alter the curvature of the eye to allow better focus. Myopia can be corrected with the use of numbing eye drops prior to the procedure.
