OBJECTIVE: To evaluate the application of Hansatome in excimer laser in situ keratomileusis(LASIK).
METHODS: Two hundred and sixty-six cases(514 eyes) with myopia were treated with the Hansatome microkeratome and the excimer laser. According to the preoperative spherical equivalent refraction, the patients were divided into three groups: < -8.0 D, -8.0 D(-)-15.0 D and > -15.0 D. The advanced rails of Hansatome microkeratome was revolving, then the stalk of corneal cap was over cornea. Postoperatively for six months all patients had been followed up on visual acuity, refractive status and complication.
RESULTS: The uncorrected visual acuity in three groups was 0.5 or better in 303, 144 and 28 of the eyes, 278, 124 and 10 had vision of 1.0 or better six months after operation. The refractive status tended to be stable about four to six months after the operation. The complication of operation included corneal epithelial excoriation, incomplete cap, free cap, interfacial foreign bodies, glare, etc. The learning curve of the technique requested half a year.
CONCLUSION: The Hansatome microkeratome in LASIK is effective for the correction of myopia and it has better safety. The complication of the stalk of corneal capover cornea might be less than which of the inside the nose.
