Photorefractive keratectomy or PRK eye surgery is a laser eye operation for correcting slight to medium shortsightedness, hypermetropia &/or astigmatism. Basically, cornea (the translucent frontal portion of the eye that permits light passing via it) is reshaped in every laser vision rectification surgery. In PRK eye surgery, surgeons employ a laser beam delivering a pulsed shaft of UV light on the corneal surface instead of underneath it which is often the case with LASIK. Pros of PRK Eye Surgery It has high accuracy in rectifying several cases of shortsightedness. Around eighty percent of patients who undergo this procedure are able to get normal visual acuity post-procedure sans eye glasses or eye contacts. Twelve months post-procedure, ninety-five to ninety-eight percent of patients  [...] 

Refractive eye surgery is immensely beneficial in rectification of ocular refractive errors and reducing dependence of eye glasses and contact lenses. It has established success rates in diminishing refractive error issues like myopia – nearsighted vision, astigmatism – corneal elongation, hyperopia – farsighted vision among several others. The remedy encompasses 4 forms of refractive eye surgery methods, namely: Corneal incision. Flap and photoablation. Implants. Thermal methods. In present times, current technology facilitates usage of laser for corneal re-shaping. In flap method, the doctor incises a small flap in the cornea for re-shaping the tissue beneath and rectifying refractive error. Lasik or Laser Assisted In-Situ Keratomileusis are popularly chosen in the area of refractive  [...]
