Cleaner LASIK is possible.

LASIK (laser in situ keratomileusis) surgery is the most frequently performed refractive procedure for correcting nearsightedness, farsightedness, and astigmatism. Its popularity increased over the late 1990's, rapidly replacing Radial Keratotomy (RK). The LASIK operation and excimer laser surface ablation procedures gained the rapid acceptance of refractive physicians and patients over the RK procedure because of greater predictability, precision, safety, and stable vision. In the mid 90's, when doctors first began performing LASIK, it was referred to implicitly as the "FLAP and ZAP" procedure. This of course was an overly confident misstatement as unfamiliar complications began to appear. One of the ultimate goals in performing any surgical procedure is to minimize less than desirable outcomes arising from both infectious and non-infectious contaminants entering the surgical field. This is especially true of all corneal procedures, such as LASIK, where the normal mechanisms for fighting contaminations are diminished.

From the full text:

Quote:
Stage II begins when the corneal flap is reflected (opening the incision)
and is completed with the corneal flap returned and sealed in its original position (closure of the incision): surgical incision exposure to surgical incision closure. During this stage invasive solids and fluids can arise owing to the involuntary introduction of infectious organisms, epithelial
cells, debris, oils, etc. into the stroma after the corneal flap is reflected back off the corneal surface. Manipulations of the epithelial surfaces, flap, flap bed, introduction and extraneous use of instruments at the interface, flap folding, irrigation and cleansing of the surface, coupled with possible contaminations from the eyelashes, stromal bed tissue, tear ducts, proliferation and/or migration of epithelial cells, and the limbus throughout the second stage of the LASIK procedure may contribute to less than desirable outcomes.

Moreover, splatter from the ablation plume can partially mask the laser beam impairing the laser?s efficiency and could create undesired outcomes that require future surgical correction. Excimer surgeons sometimes have observed the generated plume to carry large particles, which can drop out onto the surgical field creating additional contamination in the region of the incision. These particles also may adhere after splattering onto the laser?s last optic resulting in irregular etching. Both events cause grief for the surgeon and patient and may require complex surgical intervention in an attempt to correct poor outcomes. Additionally, splatter, smoke, and large particles are possible health and safety issues for the surgeon, medical staff, and patient.
