To compare corneal light scattering after laser in situ keratomileusis and photorefractive keratectomy in rabbit eyes.
For laser in situ keratomileusis, a 5-mm, -10-diopter spherorefractive resection was performed on the stromal bed under a corneal flap. Corneal light scattering was objectively measured for 12 weeks, and compared to corneal light scattering after photorefractive keratectomy (5 mm, -10 diopters).
Corneal light scattering was significantly lower in the laser in situ keratomileusis group than in the photorefractive keratectomy group at all time points after surgery (P < .01 at weeks 1 through 6, and P = .03 at week 12).
In this experimental study, laser in situ keratomileusis resulted in significantly less corneal light scattering than photorefractive keratectomy.
比较兔眼准分子原位角膜磨镶术（LASIK）和准分子激光角膜切削术（PRK）后角膜的光散射情况。
对于准分子原位角膜磨镶术，在角膜瓣下的基质床上进行5毫米、-10屈光度的球形屈光性切除。客观测量角膜光散射12周，并与准分子激光角膜切削术后（5毫米，-10屈光度）的角膜光散射进行比较。
术后所有时间点，准分子原位角膜磨镶术组的角膜光散射均显著低于准分子激光角膜切削术组（术后1至6周P <.01，术后12周P =.03）。
在本实验研究中，准分子原位角膜磨镶术导致的角膜光散射明显少于准分子激光角膜切削术。
