An experimental study on the effect of collagen shields and therapeutic contact lenses on corneal wound healing.

摘要: We evaluated the effects of collagen shields and therapeutic contact lenses on corneal wound healing in rabbits. A was created by mechanical removal central 6-mm zone epithelium basement membrane 30 eyes 15 The animals were divided into three groups: five rabbits first group treated with a shield one eye lens other eye. In remaining two groups, either or applied served as control. radius area measured at 0, 6, 24, 48 h after wounding. Linear regression analysis revealed significant reduction time all groups. rate found to be 0.52 +/- 0.08 mm2/h shield, 0.54 0.05 lens, 0.43 0.06 control group. Comparison study groups Bonferroni modification variance no statistically difference between any (p > 0.05), whereas significantly larger size observed compared treatment times studied < 6 h; p 0.001 24 h). conclusion, our results indicate that both enhance rabbit eyes.
