The latest trends in corrective eye treatments uses an excimer laser in surgical eye procedures that is performed to correct one’s eyesight. One great benefit from such treatment would be the reduction or elimination for the need of wearing eyeglasses and contact lenses.
LASIK as it is often called is Laser Assisted in Situ Keratomileusis is a surgical eye procedure that permanently changes the shape of the cornea, the clear covering in front of the eye, using an excimer laser. The goal of the treatment is by reshaping of the cornea to correct the refractive error and achieve vision improvement.
As with any elective medical procedure, the possible complications should be considered prior to treatment. It is best to do extensive research by receiving as many objective inputs from friends who have had the procedure and due diligence in evaluation of the professionally qualified doctors who perform the surgery, but ultimately the important decision should be your own.
Many possible complications can be avoided with proper testing and screening to ensure that one is a good qualified candidate for LASIK eye surgery. Careful selection of an experienced eye surgeon who has performed hundreds or thousands of procedures also increases your chances of a successful surgery.
The various types of laser eye surgery complications include:
Visual Aberrations. Symptoms include glare, double vision, ghosting, halos, starbursts, loss of contrast sensitivity, and problems with low-light or night vision. Symptoms often disappear as the eyes heal. Treatment includes eyedrops or an enhancement procedure (further laser treatment). Sometimes caused by oversized pupils, when the pupils are wider than the treatment zone.
Dry Eye. Symptoms are dry, itchy eyes, often with redness and the feeling of having something in the eye, and sometimes pain. Symptoms often disappear as the eyes heal. Treatment includes artificial tears or punctual occlusion (blocking the tear ducts).
Infection. Symptoms include eye redness and/or oozing, sometimes pain. Treatments include eyedrops and oral medications.
Incomplete Correction (undercorrection, overcorrection, or regression). Symptoms will be blurry, less-than-perfect vision. Possible treatments include glasses or contact lenses, eyedrops, or an enhancement procedure (further laser treatment).
Irregular Astigmatism. Symptoms include double vision or ghost images. May be caused by an irregular corneal surface or when the laser correction is not properly centered on the eye. Possible treatment requires an enhancement procedure (further laser treatment).
Flap Folds or Wrinkles. Minor instances of folds or wrinkles in the corneal flap do not require surgical treatment or affect vision, but some cases affect vision and further treatment is required to reposition the flap. Possible causes include malposition of the flap (laying it down in a different position from where it was lifted) or rubbing the eyelids before the flap has had a chance to bond.
Keratectasia. A condition that occurs when the corneal flap is cut too deeply or there is excessive removal of corneal tissue which causes the weakened cornea to bulge. This results in distorted vision which usually cannot be corrected with further laser enhancement. Rigid contact lenses may be prescribed to hold the cornea in place.
Diffuse Lamellar Keratitis (DLK). A unique and rare condition that occurs with the appearance of dead cells underneath the corneal flap, causing inflammation and scarring. Prompt treatment with antibiotics and/or topical steroids is necessary to avoid potentially permanent vision loss. It may also be necessary to lift and scrape the flap to remove the dead cells.
Epithelial Ingrowth. A rare condition in which epithelial cells, which normally cover the surface of the cornea, grow beneath the flap. Most epithelial ingrowth does not affect vision or need further treatment. Sometimes eyedrops may be prescribed. Some cases require surgery to lift the flap and wipe the cells off. If left untreated, however, some cases can cause vision loss.
I know of a friend who has recently undergone such surgical procedure and experienced severe complications but was the result of negligence on his part. The week after the surgery, he went sailing on his yacht and this has caused his eyes painful swelling, discomfort and vision complications.
As continuing research improves the development of more quality precision excimer lasers, it is my honest assessment to best postpone the decision for delicate eye surgery until such time when the technology has already reached a certain degree of perfection.
But when the potential vision benefits are urgent and the need to avail of laser eye surgery is immediate and a priority to the patient, it is most important to conduct extensive personal research on the procedure and the professional qualification and experience of the prospective surgeon so as to minimize the possibility of surgery related complications.

What about you, do you think the end benefit are worth the risks? Would you have laser eye surgery performed on you?
