Why LASIK surgery is preferred than other eye surgical procedures?

LASIK allows people to perform most of their everyday activities without wearing any corrective lenses. If your vision is fully corrected with LASIK, you will need to wear glasses in your 40s or 50s due to presbyopia. But if you are interested in correcting your presbyopia and reduce the dependence upon the eye glasses, you can try the strategy known as monovision. This technique corrects your vision to allow for near vision in one eye and distance vision in the other eye. Some patients respond so positively to monovision demonstration with trial frames during preoperative evaluation.

It is important to discuss your lifestyle, including your work and recreational and leisure activities, with your eye surgeon before deciding to go ahead with LASIK since some work, sports and other activities are not compatible with LASIK.

The advanced surgical procedure involved in LASIK eye surgery

LASIK is performed in an outpatient surgical setting, with the patient reclining under a surgical device called an excimer laser. Initially your eye is made numb with a few drops of topical anesthetic. An eyelid holder, called a speculum, is placed between the eyelids to keep them open and prevent you from blinking.A suction ring placed on your eye, lifts and flattens the cornea and prevents your eye from moving. You may feel pressure from the eyelid holder and suction ring.

Vision appears dim or goes black from the time suction ring is placed on your eye until it is removed. Then surgeons creates hinged flap of corneal tissue using an automated micro surgical device like laser or microkeratome blade.The corneal flap is lifted and folded back. The excimer laser that has been programmed with measurements specifically for your eye is then centered above your eye.

You will look at a special pinpoint of light that is known to be target light and the laser sculpts the exposed corneal tissue. After the laser has reshaped your cornea, the surgeon replaces the flap in position and smoothens the edges without placing any stitches.Your corneal flap will never adhere to the surface of the eye with quite the same strength it did prior to the surgery, so there is a rare risk of the flap becoming displaced with sufficient force.

Important precautions to be taken after LASIK surgical procedure

  • After surgery, you should avoid rubbing the eye, which may cause the flap to shift out of place. To protect the cornea for healing, the surgeon places a transparent protective shield over your eye. The shield is needed only at night to prevent you from rubbing the eye during sleep.
  • You should arrange someone to take you home after the surgery. Taking complete rest of the day is recommended.
  • After LASIK surgery you will get eye drops to prevent infection and other inflammation during healing process and to lessen dryness.
  • Follow every instruction given by specialists and attend follow-up appointments. Keep in mind that it may take nearly six months for complete stabilization of your vision.
