Abstract:
AIM:To investigate the safety and complications of femtosecond laser corneal small incision lenticule extraction(SMILE) procedure and discuss the prevention and treatment.METHODS: We retrospectively studied the complications of 403 patients(799 eyes) with myopia and myopic astigmatism treated by SMILE.RESULTS: All the patients underwent the operation successfully.Only 1 case(1 eye)suffered from dark spot and changed to femtosecond laser-assisted LASIK(FS-LASIK), 5 cases(5 eyes, 0.6%) suffered from the suction loss, 11 cases (17 eyes, 2.1%) developed opaque bubble layer.All patients gained perfect uncorrected visual acuity(UCVA) (20/20).The best corrected visual acuity(BCVA) did not decrease after operations.The incidence of haze and diffuse lamellar keratitis was low (0.3% and 0.4%, respectively)and no other complications were observed.There was 9 eyes in 6 patients (1.1%) found regression of refraction at 6mo after surgery, while the UCVA of rest patients reached 1.0 at 3mo after surgery.CONCLUSION: The SMILE procedure has high safety for myopia and myopic astigmatism.Effective prevention and management of the complications is the key to achieve the satisfactory visual acuity.
