Abstract:
AIM:To evaluate the clinical effects of femto-LASIK using new Ziemer LDV Z6 femtosecond laser machine (Z6).
METHODS: Two - hundred cases ( 400 eyes ) was randomly separated into two groups: Group A included 200 eyes which corneal flaps were made by Z6, and Group B included rest of 200 eyes which corneal flaps were examined by a traditional Ziemer LDV CrystalLine femtosecond laser machine (CrystalLine). Visual acuity, slit lamp, refraction, Sim-K average, intraocular pressure (IOP), non-invasive tear break-up time (NIAvg-BUT), operation difficulty and complications were compared between two groups preoperatively and postoperatively.RESULTS:There was no significant differences between two groups in visual acuity, refraction, Sim-K average, IOP and NIAvg - BUT either preoperatively or 6mo postoperatively (P>0. 05). Although there were significant differences in operation difficulty and complications were found between two groups ( P< 0. 05 ), there was no serious complication in any group. Furthermore, a clear demarcation line could be observed in the cornea of Group A postoperatively.
CONCLUSION:More careful and strict requirements are needed when using the new Z6 femtosecond laser for corneal flaps.
