Randomized Controlled Trial
Comparison of postoperative pain following laser-assisted subepithelial keratectomy and transepithelial photorefractive keratectomy: a prospective, random paired bilateral eye study.
To compare postoperative pain following laser-assisted subepithelial keratectomy (LASEK) and transepithelial photorefractive keratectomy (T-PRK, two-step surgery) and alleviate postoperative subjective pain. ⋯ Good visual acuity was obtained in both groups at postoperative 3 months. Compared with those in the T-PRK group, patients undergoing had less discomfort in the LASEK group, which may be associated with corneal epithelial activity. The changing curve of subjective pain in the T-PRK group was relatively flat and stable at postoperative 3 days.
