简要总结
The primary objective of this study is to compare two post operative drop regimens for the management of dry eye and control of healing using FDA-approved ophthalmic solutions.
详细描述
This comparison will be made between bilateral eyes of the same patient following excimer laser ablation using the FDA-approved LADARVision 4000 Excimer Laser System or the WaveLight ALLEGRETTO WAVE™ Excimer Laser System. Post operative questionnaires regarding the use of the drops will be compared. Tear osmolarity and tear breakup time will be evaluated using Tear Lab and OQAS II.
