Our Houston optometrists Dr. Aric Welton, Dr. Stephanie Lozano, and Dr. Elizabeth Bell are committed to helping you achieve the best vision and comfort with your contact lenses. We are proud to offer all types of contact lens examinations, including soft lenses, rigid gas permeable (RGP) lenses, and custom scleral lenses. Our contact lens specialists are skilled in fitting complex and custom lenses, particularly for patients with keratoconus or prior eye surgery.

Contact Lens Services and Fitting

Soft Contact Lenses

Soft disposable contact lenses work well for many patients without eye disease or previous surgery.  Our doctors fit all types of soft lenses, including toric (for astigmatism), multifocal, monovision (one eye for distance and one eye for near), daily disposables, and colored or enhancer lenses.

Rigid Gas Permeable (RGP) Lenses

RGP lenses are hard lenses that provide excellent vision and may be a better option for some patients due to their prescription or corneal shape.  These contact lenses are typically smaller than soft lenses and can last for several years when cared for properly. These lens types include single vision, bitoric (for high astigmatism), and bifocal lenses. They may also be used for patients with keratoconus, pellucid marginal degeneration, or previous corneal surgery or injury.

Scleral Lenses

Scleral contact lenses are custom-made large diameter lenses that provide excellent vision and comfort to patients who are unable to wear other types of lenses due to severe dry eyes, corneal diseases like keratoconus, prior corneal surgeries like transplants and RK, or high prescriptions. Because of the large diameter, the lens rests on the sclera, or white portion of the eye, which is less sensitive than the cornea. This allows the lens to hold a cushion of fluid against the cornea that both keeps the cornea well-hydrated and corrects the vision. The lens is custom designed to provide an optical surface that can correct for visual aberrations better than standard soft contact lenses or glasses.


Diagnostic Eye Center is excited to offer Orthokeratology, also known as Ortho-K. This advanced technology involves the fitting of a rigid gas permeable lens that is worn overnight to gently reshape the cornea, allowing you to see clearly after removing the lenses in the morning. Ortho-K is primarily used for patients with mild to moderate nearsightedness and can help to slow the progression of myopia in children. Ortho-K is completely reversible, so there is no effect on a patient’s ability to have refractive surgery later in life.
