The study aimed to establish the outcome of multifocal contact lenses (MFCL) (Multistage + 1.50D and Proclear + 3.00D) on myopia progression and axial length elongation over an 18-month period.
Thirty myopic schoolchildren (5 males and 25 females) aged between 13 and 15 years were randomly assigned to wear either single vision contact lens (SVCL), Multistage MFCL + 1.50D, or Proclear +3.00D MFCL for 1½ years using a double-masked design. Cycloplegic refraction, corneal curvature, and axial length were measured.
Myopia progression was controlled by 38.6% and 66.6% in children wearing Multistage + 1.50D and Proclear +3.00D MFCL, respectively, in comparison to children wearing SVCL over an 18-month period. In terms of axial elongation, this study found a 31.1% and 63.2% control in axial elongation over 18 months of treatment in comparison to the SVCL group. No statistical significant difference in corneal curvature was found between initial and last visits for all the three groups (SVCL, = 0.90; Multistage + 1.50 MFCL, = 0.78, and Proclear + 3.00 MFCL, = 0.05).
Proclear +3.00D MFCL was revealed to cause slow development of myopia and axial elongation among myopic schoolchildren. MFCL with higher add powers could be more effective on myopia progression in comparison with moderate add powers.
本研究旨在确定多焦点隐形眼镜（MFCL）（Multistage + 1.50D和Proclear + 3.00D）在18个月期间对近视进展和眼轴长度延长的影响。
30名年龄在13至15岁之间的近视学龄儿童（5名男性和25名女性）采用双盲设计，随机分配佩戴单焦点隐形眼镜（SVCL）、Multistage MFCL + 1.50D或Proclear +3.00D MFCL，为期1年半。测量睫状肌麻痹验光、角膜曲率和眼轴长度。
与佩戴SVCL的儿童相比，佩戴Multistage + 1.50D和Proclear + 3.00D MFCL的儿童在18个月期间近视进展分别得到38.6%和66.6%的控制。在眼轴延长方面，本研究发现与SVCL组相比，在18个月的治疗中，眼轴延长得到31.1%和63.2%的控制。三组（SVCL，= 0.90；Multistage + 1.50 MFCL组，= 0.78；Proclear + 3.00 MFCL组，= 0.05）初始和末次检查之间角膜曲率无统计学显著差异。
研究表明，Proclear +3.00D MFCL可减缓近视学龄儿童近视的发展和眼轴延长。与中等加光度数的MFCL相比，加光度数较高的MFCL对近视进展可能更有效。
