Abstract:
AIM:To explore the effect of base curve aspheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism, and its influence on ocular surface morphology and tears.METHODS:A total of 232 adolescents(464 eyes)with myopia and moderate to high astigmatism treated in the hospital from December 2018 to March 2020 were selected as the research subjects. They were randomly divided into control group(116 patients, 232 eyes)and observation group(116 patients, 232 eyes). The control group was treated with base curve spheric orthokeratology lens, while the observation group was treated with base curve aspheric orthokeratology lens. Comparison was made between the two groups in terms of the correction effect, objective visual quality, ocular surface morphology, tears related indicators before and after wearing the lenses, and the incidence of complications after wearing the lenses for 12mo.RESULTS:After wearing the lenses, the uncorrected visual acuity(UCVA)and diopter of the two groups were significantly improved. The UCVA and diopter of the observation group were significantly better than those of the control group(all P<0.05). After wearing the lenses, the whole-eye and corneal coma, spherical aberrations and high-order aberrations were significantly increased, while Strehl ratio and modulation transfer function were decreased in the two groups. Trefoil aberrations was significantly increased(all P<0.05). These indicators in the observation group were better than those in the control group(all P<0.05). After wearing the lenses, the epithelium fluorescence staining scores, ocular surface disease index(OSDI)scores were significantly decreased in the two groups(P<0.05), but there was no statistically significant difference between the two groups(P>0.05); The noninvasive tear breakup time(NI-BUT)of the two groups were significantly decreased after wearing the lenses(P<0.05), but there was no statistically significant difference between the two groups(P>0.05). The Schirmer Ⅰ test and tear meniscus height of the two groups showed no statistically significant difference before and after wearing the lenses(P>0.05). The incidence rates of complications in the observation group and the control group after wearing the lenses were close(6.9% vs 6.0%, P >0.05).CONCLUSION:Base curve aspheric orthokeratology lens is superior to base curve spheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism in terms of correction effect and objective visual quality. The two lenses have similar influence on ocular surface morphology and tears.
