Which contact lens types are ideal for myopic visually impaired patients?

• A. Extended wear gas-permeable only
• B. RGPs, soft
• C. Glass lenses
• D. Daily disposable hydrogel

Answer: (B)

For correcting myopia in visually impaired patients, the best approach uses both rigid gas-permeable and soft contact lenses. Soft lenses offer comfortable wear and easy fitting for many patients with mild to moderate myopia, making them a common first-line option. Rigid gas-permeable lenses provide crisp, stable vision and can be especially advantageous when the cornea is irregular or when high myopia is present, because their rigid surface maintains a consistent optical shape. Modern RGP materials also allow ample oxygen transmission, supporting corneal health, and they can be tailored to fit a variety of eye shapes and refractive needs. This combination covers a wider range of prescriptions and corneal conditions than any single lens type, offering flexible options for optimizing vision.

The other choices are less ideal for a broad myopic population. Extended wear gas-permeable lenses limit wear to those who can tolerate overnight use and require careful monitoring for safety; glass lenses are obsolete as contact lenses today; daily disposable hydrogel represents only one soft lens option and may not meet the needs of higher prescriptions or irregular corneas as well as the broader soft and rigid options.
