Are you tired of your eye? You can reduce the use of the eye glasses or contacts by getting Lasik surgery. This corrective can even enable you to stop using them forever. Lasik stands for laser in situ keratomileusis. The procedure uses a laser that goes beneath the cornea flap (in situ) to change the shape of the cornea (keratomileusis). Lasik is done to repair your vision and also corrects refractive errors.
A laser excimer is used in lasik surgery. This is manufactured mainly by Bausch and Lomb, Alcon, Visx, Wavelight, Nidek and others. There are various types of lasik procedures including a traditional laser procedure, a wavefront optimized procedure and a wavefront guided treatment.
First, the conventional laser treatment is the most asked-for type of Laisk. It provides treatment based on the vision prescription of the patient. The parameters of the treatment are customized to the patient. Even though this treatment is the most common, it can result in side effects like glare, halos, and night vision - side effects not caused by the other treatments.
The wavefront optimized treatment is performed with a new wavelight laser. In addition to the eyesight problems that can be resolved with the conventional laser treatment, this one can help with more serious problems. Corneal curvature and thickness can be calculated easily. The laser is used around the cornea area. It flawlessly resolves the usual drawbacks of the traditional process.
Lastly, the the wave-front guided treatment is a third option. It is also sometimes called Custom Lasik or Wave-front Lasik. It is the same as the conventional laser treatment, but has one exception. In this process severe irregularities in the optical system of a patient can be identified beforehand. It is done using specialized wavefront mapping.
Like all procedures, this one has its share of possible complications too. Over correction and under correction of your ability to see can be the outcome post surgery. Contacts might still be required. Your eye sight might become affected. You could even lose your eye sight.
Although there are risks, this surgery is considered very safe. The procedure's accuracy level is very high for the correction of myopia, hyperopia and astigmatism. It needs much less time and the hospital stay is reduced. The surgery is not painful. Most of the time, a single process totally resolves the vision issue. It also makes it more comfortable to see and sometimes also vastly improves your eye sight.
There are a few more things that you should be aware of when you opt for lasik surgery: Your refractive error, treatment options, type of laser prescribed and reason for your chosen procedure type. Memorize your corneal shape and curvature, career issues, vision stability, age, corneal thickness, medical or eye diseases, pupil size, dry eyes and any prior eye surgeries, for discussion of them with a eye doctor.
Use caution when selecting the doctor who will perform your surgery. The technician must be knowledgeable, well reputed, possesses state of the art technology, and have good availability in times of post surgical procedure.
Talk with your eye surgeon to determine if Lasik surgery is the right decision for you.
