Abstract:
Objective:To compare the effectiveness and clinical safety between the two through the observation of Orthokeratology lens and multifocal soft lens.
Methods:By using prospective longitudinal design, sixty patients (120 eyes) with orthokeratology lens and multifocal soft lens were selected. After 1, 3, 6 and 12 months, our tests were conducted, including ocular surface disease index (OSDI) questionnaire, tear break up time(BUT), corneal fluerescein staining (CSF) and meibomian gland function assessment, before and after wearing glasses, ocular axis and refraction in 6,12 and 18 months after were evaluated to assess the effect of myopia control.
Results:But in the orthokeratology lens group was lower than the soft lens group after two months. The difference was statistically significant( t=4.35, P <0.05). After 1 month of wearing glasses, BUT in the orthokeratologylens group was shorter than before( F=305.83, P <0.05). In the group of soft lens, there was no statistically significance before and after wearing glasses( F= 0.38, P >0.05). There was no difference in corneal fluorescence staining (CSF) and meibomian gland function between the two groups before and after wearing glasses.( F time=1.55, 1.38, 10.15, 1.50, P >0.05, F group=2.31, 0.02， P >0.05). After 18 months of wearing orthokeratology lens, the average degree of spherical lens increased by -0.53 D, which was different from that before wearing( F=6.54, P <0.05). After wearing soft lens 18 month, the average degree of spherical lens increase by -0.34 D, which was different from that before wearing( F=2.88, P <0.05). After 18 months of wearing glasses, there were differences in the growth of ocular axis between the two groups( F =2.73, 2.83, P <0.05).
Conclusion:Orthokeratology lens and multifocal soft lens are both safe and effective measures to control myopia.
