Effect of opaque bubble layer on the ocular cylotorsion compensation during FS-LASIK procedures / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To evaluate the effect of opaque bubble layer(OBL)on the ocular cylotorsion compensation during FS-LASIK procedures. <p>METHODS: Prospectively clinical study. From July 2019 to September 2019, two-hundred FS-LASIK patients(400 eyes)were randomly included into this study. The total OBL incidence, flap-out OBL incidence, flap-in OBL incidence, incidence of dynamic cyclotorsion component(DCC)and incidence of static cyclotorsion component(SCC)were statistically analyzed. <p>RESULTS: OBL developed in 183 eyes of 400 FS-LASIK eyes, with a total OBL incidence of 45.8%. DCC was successfully performed on 397 eyes, with a total DCC incidence of 99.2%. SCC was successfully performed on 293 eyes, with a total SCC incidence of 73.2%. Neither flap-out OBL nor flap-in OBL could disturb the successful implementation of DCC during the operation(<i>P</i>>0.05). Both flap-out OBL and flap-in OBL could impact the SCC implementation and make it fail(<i>P</i><0.05).<p>CONCLUSION: OBL can result in failure of SCC implementation during the FS-LASIK procedures.
