Custom gas permeable (GP) lenses are a type of rigid gas permeable contact lens that is individually designed and manufactured to fit complex corneas. These lenses are highly customized to address the unique shape and prescription of patients who can’t be fit with standard contact lenses.
Here are some key features and benefits of custom GP lenses:
Custom Design: Custom GP lenses are made-to-order based on detailed measurements of the eye called topography. This customization allows for a precise fitting of the lens in addition to the ability to treat a range of refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia.
Irregular Corneas: These lenses are particularly beneficial for individuals with irregular corneas, such as those with keratoconus, post-surgical corneal irregularities, or corneal scarring. The lenses can be tailored to match the shape of the irregular cornea, providing clearer and more stable vision.
Complex Prescriptions: Patients with complex vision prescriptions that cannot be effectively managed with off-the-shelf lenses often benefit from custom GP lenses. This includes those with high astigmatism or unusual combinations of prescriptions.
Comfort and Fit: Custom GP lenses are designed for a precise fit, which enhances comfort during wear. The fitting process involves taking detailed measurements of the eye’s surface called a topography, so the curvature, diameter, thickness, and edge profile of the contact can all be adjusted for the best fit and comfort.
Improved Visual Acuity: Because of their tailored design, custom GP lenses can provide excellent visual acuity and image quality. They can reduce or eliminate issues like halos, glare, and distortion that some wearers experience with standard lenses.
Presbyopia Correction: Custom GP multifocal lenses can be designed to address presbyopia, allowing wearers to see clearly at various distances, from up close to far away without the need for reading glasses.
Optimal Tear Film Management: Custom GP lenses can be designed with specific parameters to optimize the interaction between the lens and the tear film. This can help reduce dryness and discomfort during lens wear allowing for tear exchange under the lens.
Specialized Lens Materials: Custom GP lenses can be manufactured using gas permeable materials to allow oxygen through to the eye to ensure optimal eye health.
