Influence of orthokeratology combined with vision therapy and Clouclip on accommodation

AIM: To observe the effect of orthokeratology combined with vision therapy and Clouclip(OCVTC)on myopic children with dysfunctional accommodation.METHODS: A prospective, non-randomized control study was conducted on 99 myopic children(99 eyes)with dysfunctional accommodation at the optometry center were of Langfang Aier Eye Hospital from April 2022 to January 2023. and they selected and divided into three groups: 39 children in OCVTC group, 30 in orthokeratology(Ortho-k)group, and 30 in single vision spectacle lens(SVL)group. The OCVTC group received office-based accommodative therapy for 3 mo and home reinforcement for 3 mo, and Clouclip was used in the first 3 wk to monitor and remind children of eye habits; the accommodative amplitudes and facility were measured at baseline, 3, 6, and 12 mo after treatment.RESULTS: The OCVTC group showed significantly better improvement in accommodative amplitude compared with both the Ortho-k group and the SVL group(all P<0.05), and the Ortho-k group was better than the SVL group at 3, 6, and 12 mo after the intervention(both P<0.05). Similarly, accommodative facility was significantly enhanced in the OCVTC group compared with the other groups at 6 and 12 mo after intervention, and the Ortho-k group was better than the SVL group(all P<0.05). Both accommodative amplitude and facility in the OCVTC group were significantly improved at 3, 6, and 12 mo after the intervention compared with the baseline(all P<0.05). Additionally, 13%(5/39)of cases in the OCVTC group showed a decrease in accommodative amplitude at 12 mo after treatment, with no cases showing a decrease in accommodative facility.CONCLUSION: For myopic patients with dysfunctional accommodation, orthokeratology combining with visual training and Clouclip will enhance accommodative amplitude and facility, and maintain a stable effect over a long time.
