简要总结
This is a crossover study of two types of contact lenses (toric orthokeratology and soft multifocals). Primary aims are to quantify correction of astigmatism, subjective and objective visual performance, aberrometry, peripheral refraction and bacterial bioburden between toric orthokeratology and soft toric multifocal contact lenses.
