All about Lasik Surgery: Cures and Treatment Options

By Nakul Jain LASIK stands for Laser-Assisted In Situ Keratomileusis. Lasik surgery is a vision correction procedure by performing surgery which permanently reshapes the cornea which is a clear top layer of the eye through an excimer laser technology so the eye can focus correctly and vision becomes clear. A knife, called a microkeratome, is used make a cut in the cornea to make a flap which is folded to show the middle of the cornea which is called stroma. Once it is revealed technically controlled laser rays are produced to vapourize a particular portion of the stroma and then the flap is put back in place. The range of laser rays and the particular portion of stroma is decided by the power of myopia or hypermetropia of eyes or the number being used for glasses or lenses. You may need lasik surgery if you are nearsighted, farsighted, or have astigmatism. You may go in for the surgery after an examination with the ophthalmologist as you need to abide by certain conditions 1) age- being an adult 2) free from cataract 3) no eye infection or inflammation 4) No other health issues which might be affecting your eyes such as Rheumatoid Arthritis or Diabetes which might be causing vision problem hence lasik treatment would not help in any case Pre surgery requires to stop wearing contact lenses a month before surgery as Contact lenses change the shape of your cornea and the cornea is required to take its normal shape for accurate measurements vfor the correct surgical plan These measurements, which determine how much corneal tissue to remove, may need to be repeated several times before surgery to make sure they have not changed The procedure The surgery should take less than 30 minutes. You will lie straight on your back in the room containing the laser system. The laser system includes a large machine with a microscope attached to it and a computer screen. A numbing drop will be placed in your eye, the area around your eye will be cleaned, and an instrument called a lid speculum will be used to hold your eyelids open. A ring will be placed on your eye and very high pressures will be applied to create suction to the cornea. Your vision will dim while the suction ring is on and you may feel the pressure and experience some discomfort during this part of the procedure. The microkeratome, a cutting instrument, is attached to the suction ring. Your doctor will use the blade of the microkeratome to cut a flap in your cornea. The microkeratome and the suction ring are then removed. You will be able to see, but you will experience fluctuating degrees of blurred vision during the rest of the procedure. The doctor will then lift the flap and fold it back on its hinge, and dry the exposed tissue. The laser will be positioned over your eye and you will be asked to stare at a light.. It is very important to stare straight on the light as the laser is positioned accordingly and a wrong placement might have extremely negative effect. When your eye is in the correct position, the laser will start. As the laser starts you might experience a burning smell A computer controls the amount of laser energy delivered to your eye. Before the start of surgery, the computer would have been programmed to vaporize a particular amount of tissue based on the measurements taken at your initial evaluation. After the pulses of laser energy vaporize the corneal tissue, the flap is put back into position. A shield should be placed over your eye at the end of the procedure as protection, since no stitches are used to hold the flap in place. It is important for you to wear this shield to prevent you from rubbing your eye and putting pressure on your eye while you sleep, and to protect your eye from accidentally being hit or poked until the flap has healed. Post surgery 1) You should avoid going out in the sun for a week 2) Avoid strain on eyes such as computer or tv 3) Do not wash eyes 4) Do not use eye makeup or cream ,lotions near eye area 5) Sports such as swimming , boxing, football, karate, etc. should not be attempted for at least a month after surgery. 6) Protect eyes from anything that would touch or hit them During the first few months after surgery, your vision may fluctuate. It may take up to three to six months for your vision to stabilize after surgery. Glare, haloes, difficulty driving at night, and other visual symptoms may also persist during this stabilization period. If further correction or enhancement is necessary, you should wait until your eye measurements are consistent for two consecutive visits at least 3 months apart before re-operation. It is important to realize that although distance vision may improve after re-operation, it is unlikely that other visual symptoms such as glare or haloes will improve. Eye surgery in India is one of the highly growing sectors in medical tourism. Several hospitals and clinics are now fully equipped to handle the inflow of patients from the West with latest technology, highly trained doctors and of course, customized treatment for every patient.
