Mean corneal sensation (SD) before and after LASIK shown as millimetres of Cochet-Bonnet filament length at each time point for each of the three groups examined
| Time | Group 1 | Group 2 | Group 3 | p Value |
|---|---|---|---|---|
| *8, 6, and 4 eyes in groups 1, 2, and 3 respectively wore contact lenses preoperatively. The average corneal sensation as measured by Cochet-Bonnet aesthesiometer for these patients was 56.87 mm, 55.83 mm, and 58.75 mm. There was no statistical difference in preoperative corneal sensation between contact lens wearers and that of the rest of the group. | ||||
