RGP Contact Lenses in Plano, TX
Rigid gas permeable lenses hold a precise optical shape against the cornea for sharper, more stable vision than soft lenses designed from detailed corneal topography and fitted personally by Dr. Beth Summers in Plano, TX
When Soft Lenses Stop Working: The Real Cost of an Imprecise Fit
For patients with irregular corneas, significant astigmatism, or post-surgical complications, soft contact lenses flex to match the eye's distorted surface, which means they inherit the distortion rather than correct it. The result is blurred, unstable vision that worsens with lens wear and often leads to years of incorrect prescriptions and mounting frustration. RGP lenses solve this by maintaining a rigid optical zone that bridges surface irregularities and creates a corrective tear layer between the lens and the cornea.
Delaying proper fitting carries measurable consequences:
Continued vision loss from uncorrected irregular astigmatism: Eyes with keratoconus or corneal scarring that are fit into soft lenses may experience progressive visual decline that could have been stabilized sooner with appropriate correction.
Corneal health risks from poorly fitting lenses: A lens that rides on a compromised surface without the right clearance and edge design can cause hypoxia, staining, and long-term structural changes that complicate future fitting.
Accumulated diagnostic costs from misdiagnosis: Patients who cycle through repeated glasses prescriptions and standard soft lens fittings before receiving a specialty evaluation often spend significantly more in the long run than those who access specialty fitting directly.
What to Expect: The RGP Contact Lens Fitting Process at Texas Contact Lens Institute
Step 1: Corneal Topography and Ocular Surface Imaging
Every RGP fitting at Texas Contact Lens Institute begins with advanced diagnostic imaging. Corneal topography captures thousands of elevation points across the entire corneal surface, producing a three-dimensional map of the eye's shape, steepness, and irregularity. For patients traveling from across the Plano area and the broader Dallas-Fort Worth region, this step ensures that fitting time is spent efficiently and purposefully.
Step 2: Lens Selection and Trial Fitting
Using the topographic dataset, Dr. Summers selects a diagnostic RGP lens whose base curve, diameter, and optical zone are appropriate for the corneal geometry. The lens is applied, evaluated under slit lamp biomicroscopy, and assessed for centration, movement, and tear exchange beneath the lens. Over-refraction refines the power. Most patients require more than one trial lens to confirm the ideal design, and Dr. Summers walks patients through exactly what she is observing at each stage so the fitting process is fully transparent.
Step 3: Custom Lens Order and Parameter Refinement
Once the diagnostic evaluation confirms the target parameters, the lens is ordered to precise specifications. RGP lenses are manufactured to tighter tolerances than soft lenses, which is what gives them their optical advantage. Turnaround time from order to lens delivery typically runs one to two weeks.
Step 4: Dispense and Wear Training
At the dispense appointment, the RGP is evaluated on the eye to assess fit, vision and comfort. New RGP patients receive hands-on instruction for insertion, removal, and daily lens care. Modifications are ordered if needed. New RGP wearers require an adaptation period, typically one to three weeks, during which wear time is gradually extended.
Step 5: Follow-Up and Long-Term Monitoring
RGP lens fittings are not completed at the dispense visit. Follow-up appointments assess corneal health, confirm that lens parameters remain appropriate as the eye changes, and allow for parameter adjustments if needed. For patients co-managed with a referring optometrist, findings are communicated directly back to that provider.
What to Look for Before Hiring an RGP Contact Lens Provider in Plano
Choosing the right specialist for RGP lenses matters significantly more than it does for routine soft lens fittings. The precision required to design a gas permeable lens that performs on an irregular or compromised cornea is a specialty skill, not a general optometry competency.
Fellowship credentials in specialty contact lenses: Look for designations such as FAAO (Fellow of the American Academy of Optometry) or FSLS (Fellow of the Scleral Lens Education Society). These credentials require demonstrated expertise in specialty lens fitting, not just general licensure. Dr. Summers holds both.
Corneal topography as a standard step: Any provider fitting RGP lenses without capturing corneal topography is relying on approximation. A quality specialist treats diagnostic imaging as non-negotiable, not optional.
A dedicated specialty lens practice: RGP fitting for complex corneas is not a service that translates well to a high-volume retail setting. Look for a clinic where specialty lenses are the primary focus, not an add-on to glasses sales and routine exams.
Transparent communication about the fitting timeline: A good-fitting relationship includes clear explanations of what each trial lens reveals, why parameters are being adjusted, and what the realistic adaptation period looks like.
Published clinical expertise or peer involvement: Providers who teach, publish, or present on specialty lens topics have their work reviewed by peers. That level of accountability reflects a different standard of practice than someone who simply offers the service.
Frequently Asked Questions About RGP Contact Lenses
-
Most patients adapt to RGP lenses over one to three weeks by increasing daily wear time gradually. Initial awareness of the lens edge in new wearers is normal and typically resolves as the corneal nerve endings adjust. Dr. Summers provides a structured wear schedule at the dispense appointment.
-
Both lens types correct irregular corneas using a rigid optical surface, but they differ in how they fit the eye. RGP lenses rest on the cornea with some movement, while scleral lenses vault completely over it and rest on the white of the eye. Scleral lenses are often more comfortable for advanced irregularity, while RGP lenses are generally less comfortable but may suit mild to moderate cases. Dr. Summers selects the appropriate design based on corneal topography and the patient's specific anatomy.
-
Texas Contact Lens Institute is an out-of-network provider and does not bill insurance directly. After the fitting is complete, a detailed medical superbill is available on request, which patients can submit independently to their insurer for potential reimbursement. Patients are encouraged to check their out-of-network specialty lens benefits before their appointment.
-
RGP lenses are more durable than soft lenses and typically last one to three years with proper care, though this depends on the patient's handling habits, lens deposits, and whether the corneal shape changes over time. Dr. Summers evaluates lens condition and parameter accuracy at each follow-up visit to determine whether the current lens remains optimal.
-
Bring your most recent prescription, any prior contact lens records or topography reports if you have them, and your current lenses if you wear them. If you are being referred by another eye doctor, bring that referral documentation. Arriving without lenses inserted for a few hours before the appointment can improve the accuracy of topography imaging, though Dr. Summers will advise you specifically when you schedule.
