Laser-Assisted In Situ Keratomileusis for Common Refractive Errors
LASIK is the term used for Laser-Assisted in Situ Keratomileusis which is a corrective surgery that reshapes the cornea with the use of a laser. This procedure is aimed to improve or correct the way the eye focuses light on the retina to improve vision or correct vision permanently.
Only ophthalmologists are allowed to perform LASIK eye surgery. This procedure is designed to correct one or two vision disorders within a single procedure by removing the natural crystalline lens of the eye with the use of a laser and replacing the lens with implantable intraocular lenses or IOLs. This method is intended for patients who have one or two of the following vision disorders or common refractive errors:
• Myopia – a vision condition where only near objects are seen clear, another word for myopia is nearsightedness
• Hyperopia – is a condition where near objects are seen blurred and only far objects are seen clear, another word for hyperopia is farsightedness
• Astigmatism – a condition wherein the eye does not focus light evenly on to the retina causing images to appear blurred and stretched out
Advantages of LASIK Eye Surgery
Laser-Assisted in Situ Keratomileusis (LASIK) is an out-patient procedure that improves vision permanently. The procedure is virtually painless and results can be experienced almost immediately after surgery. Requires short recovery period and eliminates or significantly reduces dependence on prescription eyeglasses and contact lenses.
Disadvantages of LASIK Eye Surgery
LASIK is a delicate procedure that deals with the sensitive part of the eye. Like any other type of surgery, there also also risks of complications during and after surgery. The process cannot be reversed and the procedure requires a set of aspects that need to be met prior to surgery, otherwise procedure may not be suitable.
Successful procedures in Laser-Assisted in Situ Keratomileusis has shown
a high rate of success with almost all of patients achieving desired vision.
