Therefore, it is very useful in medicine surgery, and in ophthalmology, there are many practical clinical applications for lamellar corneal surgery. The most popular corneal application such as fs-LASIK uses femtosecond laser to create a corneal flap and then cuts corneal residual stroma to correct the myopia. In order to set off a uniform flap, femtosecond laser has a pulse duration in the nanosecond(10-9second) range , and uses about μm laser spot size to produces tens of thousands of bubbles. In recent study, they found some patient who after accepted femtosecond laser surgery would product some kind of rainbow glare symptom. In this study, we went to study the cause of the rainbow glare, and used optical software to design different micro bubbles size, spot-to-spot distances, incident light wavelength, and incident light diameter on corneal to simulate the visual performance on retinal. The result is useful to investigate the cause of the rainbow glare as the diffraction of light from the microstructure bubbles created on the surface of the flap after femtosecond laser surgeon.
