AIM: To research the efficacy of LASIK ultra-thin corneal flap created with VisuMax femtosecond laser.

METHODS: Femtosecond laser LASIK was performed for 120 patients(240 eyes)with VisuMax femtosecond laser system in the production of 90-100μm corneal flap and MEL80 excimer laser corneal ablation. Then postoperative results and complications were observed.

RESULTS: The postoperative uncorrected visual acuity(UCVA)reached preoperative best-corrected visual acuity(BCVA)in 198 eyes(82.5%)one day after operation, in 236 eyes(98.3%)after 1 week of operation. And the postoperative UCVA exceeded preoperative BCVA in 141 eyes(58.75%)after 1 month of operation. No serious postoperative complications were observed in all cases.

CONCLUSION: LASIK combined with ultra-thin corneal flap created by VisuMax femtosecond laser is safe and accurate, which makes individualized corneal refractive operation more perfect.
