BACKGROUND: Various methods exist to intervene with and control myopia, including bifocal lenses, multifocal lenses, pirenzepine, atropine, soft gas-permeable contact lenses and aberration control frame lenses, each with its own advantages and disadvantages.
OBJECTIVE: To compare the clinical effectiveness of digital keratoplasty lenses and traditional orthokeratology (OK) lenses in correcting juvenile myopia.
METHODS: Sixty-one patients (122 eyes) with an average age of 10.43 ± 1.71 years and with myopia were enrolled from January 2021 to January 2022 in the treatment centre of our hospital. The patients were randomly divided into two groups. Group I (the experimental group) consisted of 30 patients who were treated with digital corneal shaping (MCT) lenses, while group II (the control group) consisted of 31 patients who were treated with traditional OK lenses. Clinical indicators, such as visual acuity, ocular axis, intraocular pressure, degree of central positioning, naked visual acuity and first-order spotting, were statistically analysed before and after fitting.
RESULTS: The naked eye vision of patients using MCT lenses was significantly improved compared with patients who used traditional OK lenses (0.95 ± 0.28 > 0.58 ± 0.25; p< 0.05). Moreover, the risk of primary spot staining was reduced (p< 0.05), intraocular pressure was lower (p< 0.05) and the centre position reached 100% in patients wearing MCT lenses, suggesting that wearing MCT lenses may be more beneficial than wearing traditional OK lenses.
CONCLUSION: Compared with traditional OK lenses, MCT lenses reduce the degree of myopia, have significant effects and have the added advantages of safety and reliability.
