Final answer:
Both Ortho-K and soft multifocal contact lenses are good options for myopia control. The final decision should be based on a full evaluation by an eye care professional who can consider the patient's specific needs and lifestyle.
Step-by-step explanation:
The student's prescription indicates a mild degree of myopia with a significant degree of astigmatism. The prescription of -0.50-2.00x180 suggests that there is a minor spherical error and a larger cylindrical error that needs correction. For myopia control, both Ortho-K (orthokeratology) and soft multifocal contact lenses can be suitable options depending on the individual patient's needs, lifestyle, and the specific goals for myopia control. Ortho-K involves the use of specially designed gas permeable contact lenses that are worn overnight to temporarily reshape the cornea, thereby reducing myopia. Soft multifocal contact lenses are worn during the day and have multiple prescription zones designed to correct vision at different distances and can also play a role in myopia control.
When making a decision between Ortho-K and soft multifocal lenses, it's important to consider factors such as the child's age, the level of myopia, astigmatism, daily activities, and the ability to properly care for the lenses. Therefore, both Ortho-K and soft multifocal lenses are good options for myopia control, and the final decision should be made in consultation with an eye care professional who can evaluate the patient's specific circumstances and recommend the most appropriate option.
