Understanding Custom Contact Lenses
A custom contact lens is manufactured based on precise measurements taken specifically from your eyes. Rather than selecting from a limited range of stock lenses, we design custom lenses with unique curvatures, diameters, and optical zones tailored to your corneal shape. These lenses can address vision problems that fall outside the range of standard lens parameters.
The customization process uses advanced diagnostic equipment to map every curve and contour of your eye surface. This detailed information allows the laboratory to create a lens that fits your eye precisely. Custom lenses can also incorporate special optical designs to correct complex refractive errors or manage irregular corneal surfaces.
Standard contact lenses are mass produced in predetermined sizes and power ranges. They work well for many people with common prescriptions and typical corneal shapes. Custom lenses, by contrast, are individually fabricated based on your specific measurements and can be adjusted in ways that regular contacts cannot.
- Custom lenses offer a wider range of prescription powers and cylinder corrections
- They can be made in unique diameters and base curves not available in standard lenses
- Custom designs can vault over irregular corneas or create specific optical zones for better vision
- They may incorporate specialized features for conditions like keratoconus or post-surgical eyes
You may benefit from custom contact lenses if you experience persistent problems with regular contacts. Common signs include lenses that feel uncomfortable no matter which brand you try, vision that remains blurry even with the correct prescription, or lenses that move excessively or fall out frequently. Some people notice their lenses dry out quickly or cause redness and irritation throughout the day.
If you find yourself constantly adjusting your lenses, experiencing fluctuating vision, or unable to wear contacts for a full day, we may recommend exploring custom options. These symptoms often indicate that standard lenses are not matching your eye shape or addressing your specific visual requirements.
Several eye conditions respond particularly well to custom contact lens designs. Keratoconus, a progressive thinning of the cornea that creates an irregular cone shape, often requires custom lenses for functional vision. People who have undergone corneal transplants, refractive surgery, or suffered corneal injuries may also need custom designs to achieve clear sight.
- Keratoconus and other corneal ectatic disorders
- High degrees of astigmatism not correctable with standard toric lenses
- Extreme nearsightedness or farsightedness beyond standard lens ranges
- Post-surgical eyes including after LASIK, PRK, or corneal transplant
- Severe dry eye syndrome requiring specialized lens designs
Custom contact lenses are one approach to managing complex vision needs and corneal irregularities. Depending on your specific condition and goals, other options may complement or serve as alternatives to contact lens wear.
- Spectacles for backup and non-contact lens wear times
- Corneal cross-linking for progressive keratoconus
- Intracorneal ring segments or topography-guided surface procedures in select cases
- Corneal transplantation for advanced scarring or ectasia when lenses are not successful
- Management of ocular surface disease, blepharitis, or meibomian gland dysfunction to improve lens tolerance
Types of Custom Contact Lenses Available
Scleral lenses are large diameter gas permeable lenses that vault over the entire cornea and rest on the white part of your eye called the sclera. These lenses create a fluid-filled space between the lens and your cornea, providing excellent comfort and vision for irregular corneal surfaces. They are particularly effective for keratoconus, pellucid marginal degeneration, and eyes with scarring or irregularity. Your provider selects high oxygen permeability materials and monitors for hypoxia-related changes during follow-up.
Because scleral lenses do not touch the sensitive cornea, many patients find them comfortable for extended daily wear when properly fitted and cared for. The fluid reservoir beneath the lens also helps keep the eye surface hydrated, making scleral lenses an excellent option for people with severe dry eye. We customize the vault depth, diameter, and landing zone of each scleral lens to match your unique eye anatomy.
Custom soft contact lenses can be manufactured in prescription powers far beyond what standard soft lenses offer. If you have high myopia, hyperopia, or astigmatism that exceeds typical lens parameters, custom soft lenses may provide the correction you need. These lenses combine the comfort of soft materials with the precision of custom design.
- Available in extended power ranges for extreme prescriptions
- Can be made in unique base curves for better fit on steep or flat corneas
- Offer custom toric designs for high regular astigmatism; for irregular astigmatism, GP, scleral, hybrid, or specialty soft designs for irregular corneas are often preferred
- May include specialized edge designs to improve comfort and stability
Custom gas permeable lenses, also called GP or RGP lenses, are rigid lenses that allow oxygen to reach your cornea while providing crisp, stable vision. We can design these lenses with unique back surface curves to match irregular corneal shapes or with special optical zones to correct complex refractive errors. GP lenses maintain their shape on the eye, making them ideal for correcting moderate to high astigmatism.
Modern custom GP designs can incorporate multiple curves, reverse geometry for orthokeratology applications, or specialized peripheral zones for better comfort. While GP lenses require an adaptation period, many patients appreciate the sharp vision and long-term eye health benefits they provide. Orthokeratology is an overnight modality that requires strict hygiene, adherence to follow-up, and prompt reporting of symptoms because overnight lens wear carries a higher infection risk.
Hybrid contact lenses feature a rigid gas permeable center surrounded by a soft lens skirt. This design combines the optical clarity of a GP lens with the comfort and stability of a soft lens. Hybrid lenses are custom designed to vault over irregular corneas while the soft skirt helps center and stabilize the lens on your eye. Some hybrid designs are intended for regular corneas, while others are built to vault irregular corneas.
We may recommend hybrid lenses if you need the crisp vision that rigid lenses provide but have struggled with GP lens comfort. The custom fitting process ensures the rigid center properly aligns with your visual axis while the soft periphery conforms to your eye shape. These lenses work well for keratoconus, high astigmatism, and other conditions requiring precise optical correction.
Custom toric lenses correct astigmatism with precision that standard toric contacts cannot match. We can design lenses with specific axis orientations, multiple cylinder powers, or unique stabilization features to keep the lens properly aligned. For patients over 40 experiencing presbyopia, custom multifocal or bifocal lenses can be tailored to your specific near and distance vision requirements.
- Custom toric designs for high, irregular, or oblique astigmatism
- Personalized multifocal zones based on your pupil size and visual demands
- Translating bifocal designs that move with your gaze
- Combination lenses addressing both astigmatism and presbyopia
Prosthetic contact lenses are custom designed to improve the appearance of eyes affected by injury, disease, or congenital conditions. These lenses can be painted to match your other eye, cover disfiguring scars, or reduce light sensitivity from iris defects. While they serve a cosmetic purpose, prosthetic lenses can also improve vision by creating an artificial pupil or reducing glare from iris damage.
We create prosthetic lenses by carefully matching the color and pattern of your healthy eye or designing an appearance that meets your goals. Some prosthetic lenses are purely cosmetic, while others combine cosmetic enhancement with vision correction. Custom cosmetic lenses can also change eye color for patients with specific aesthetic preferences, though we ensure any cosmetic lens maintains eye health and oxygen transmission. Because prosthetic lenses can be thicker and reduce oxygen transmission, wear time may be limited based on your eye health.
All contact lenses are medical devices and require a valid prescription and professional fitting. Avoid purchasing cosmetic or decorative lenses from unregulated sources.
The Custom Contact Lens Fitting Process
Your custom contact lens journey begins with a comprehensive eye examination. We evaluate your overall eye health, measure your prescription, and assess the shape and condition of your corneas. During this visit, we also discuss your vision goals, lifestyle needs, and any previous contact lens experiences. Understanding your daily activities helps us recommend the most appropriate custom lens type for you.
We review your medical history and any eye conditions that might influence lens selection. If you have dry eye, allergies, or other ocular surface issues, we address these concerns as part of the fitting process. This initial examination establishes a baseline for your eye health and helps us track any changes over time.
Custom contact lens fitting requires precise measurements beyond a standard eye exam. We use corneal topography or tomography to create a detailed three-dimensional map of your corneal surface. This technology captures thousands of data points showing the exact curvature, elevation, and shape of your cornea. The maps reveal irregularities, steep or flat areas, and asymmetries that influence lens design.
- Corneal topography maps the front surface curvature of your cornea
- Anterior segment optical coherence tomography may be used to assess scleral lens vault, corneal clearance, and edge alignment
- Pupil size measurements in different lighting conditions guide optical zone sizing
- Tear film evaluation assesses your eye's moisture and guides material selection
- Scleral profiling for scleral lens fittings maps the white part of your eye
Based on your examination findings and measurements, we recommend a specific custom lens design. We explain the advantages and characteristics of different lens types, considering factors like your eye condition, prescription, lifestyle, and comfort preferences. Some designs prioritize maximum oxygen transmission, while others focus on creating a therapeutic environment for your cornea or achieving the sharpest possible vision.
We discuss what you can expect from each lens type, including adaptation time, wearing schedule, and care requirements. Together, we select the design that best balances your vision needs, comfort, eye health, and practical considerations. This collaborative decision-making ensures you understand your custom lens choice and feel confident moving forward.
Once we order your initial custom lenses, you will return for a trial fitting. We place the lenses on your eyes and evaluate how they fit, move, and center. You will experience your vision through the new lenses, and we assess whether the optical correction meets your needs. First-time custom lens wearers often notice immediate vision improvement, though comfort may take some adjustment.
During this visit, we carefully examine the lens-to-eye relationship using specialized instruments. We look at how the lens rests on your eye, whether adequate tears circulate beneath it, and if the edges align properly. We also teach you proper insertion and removal techniques specific to your lens type. This hands-on training continues until you feel confident handling your custom lenses independently.
It is common to need adjustments after wearing your trial lenses for several days or weeks. We may modify the lens curvature, diameter, or optical design based on your feedback and our clinical observations. Small changes in lens parameters can significantly impact comfort and vision, so we carefully refine the fit until you achieve optimal results.
- Adjusting lens diameter to improve centration and stability
- Modifying edge lift or landing zones for better comfort
- Changing vault height in scleral lenses to optimize clearance
- Refining optical zones or power distribution for clearer vision
- Altering lens materials if needed for better oxygen transmission or wettability
Custom contact lens fitting is a process that typically requires several appointments over weeks or even months. Unlike ordering standard contacts, achieving the perfect custom lens fit demands patience and multiple evaluations. Each visit provides valuable information that guides further refinement, and manufacturing time between adjustments adds to the overall timeline.
We understand that multiple visits require your time and commitment, but this investment ensures your final lenses provide the best possible vision and comfort. Most patients find that the superior results make the process worthwhile. We work efficiently to minimize unnecessary appointments while ensuring we do not rush critical fitting steps that influence your long-term success.
Wearing and Caring for Your Custom Lenses
Custom contact lenses, especially larger designs like scleral lenses, require specific insertion and removal techniques. We teach you step-by-step methods tailored to your lens type. For scleral lenses, you will learn to fill the lens bowl with sterile saline before insertion, ensuring no air bubbles remain. You will practice in our office until you can confidently insert and remove your lenses at home.
Proper technique prevents lens damage and reduces the risk of eye irritation or infection. We may recommend using specialized insertion devices, mirrors, or positioning aids that make handling easier. Removal techniques vary by lens type, with some requiring gentle manipulation and others using small suction tools. Mastering these skills is essential for safe and successful custom lens wear.
- Wash and dry hands thoroughly before handling lenses. Use soap without moisturizers or fragrances
- Dry with a clean, lint-free towel. Avoid contact with water during handling
- Keep fingernails short and smooth to reduce risk of lens damage or eye injury
- Do not swim, use hot tubs, or shower while wearing contact lenses
- If using a suction tool, place it on the lens surface only, never on the cornea, and break suction gently before removal
Your initial wearing schedule starts conservatively and gradually increases as your eyes adapt. We may recommend wearing your new custom lenses for just a few hours the first day, adding an hour or two each subsequent day. This gradual approach helps your eyes adjust comfortably, especially with rigid or scleral lens designs. We provide a specific schedule based on your lens type and individual response.
- Start with limited hours and build up over one to two weeks
- Remove lenses if you experience pain, redness, or vision changes
- Avoid wearing lenses overnight unless specifically prescribed for that purpose
- Take breaks if your eyes feel tired or dry during the adaptation period
- Do not swim, use hot tubs, or shower while lenses are on your eyes
Like all contact lenses, custom lenses carry some risk of complications, especially if not worn or cared for properly. Understanding these potential issues helps you recognize early warning signs and seek timely care.
- Microbial keratitis, corneal ulcers, and sterile infiltrates
- Corneal staining, edema, or neovascularization from hypoxia
- Contact lens-induced acute red eye and giant papillary conjunctivitis
- Solution sensitivity or toxic reactions
- Lens warpage or reduced vision from overwear or poor fit
Your eye care team adjusts material, fit, and wear time to minimize these risks and monitors your eyes for early signs of complications.
Proper lens care is crucial for maintaining eye health and extending lens life. After removing your lenses each day, rinse them with the recommended solution and rub each surface gently to remove deposits and debris. We prescribe specific cleaning and disinfection products designed for your lens material, as using the wrong solutions can damage custom lenses or harm your eyes.
Never use tap water, saliva, or expired solutions on your contact lenses. Follow the exact cleaning routine we recommend, including the type of solution, rubbing time, and soaking duration. Some custom lenses require enzyme treatments or intensive cleaning weekly to prevent protein buildup. Consistent daily care prevents complications like infections, inflammation, or reduced lens clarity.
- If using a hydrogen peroxide system, ensure complete neutralization before lens insertion
- Never rinse a lens with unneutralized peroxide or put peroxide directly in the eye
- Follow the manufacturer's disk or case replacement schedule for effective neutralization
Store your custom contact lenses in a clean case filled with fresh disinfecting solution every night. Replace your lens case every one to three months to prevent bacterial contamination. Use only the solutions we recommend for your specific lens type, as custom lenses may require specialized products different from those used for standard contacts.
- Fill your case with fresh solution each time you store your lenses
- Never top off old solution with new solution in your case
- Keep solution bottles tightly capped and replace them by the expiration date
- Clean your lens case daily and let it air dry between uses
- Use preservative-free saline for scleral lens insertion, not for storage or disinfection
- Do not store lenses in saline. Saline is for rinsing or scleral lens filling only, not for disinfection
- Do not reuse or top off saline used to fill scleral lenses
- Use only drops and solutions that are labeled as contact lens compatible
Custom contact lenses typically last longer than daily disposable or monthly soft lenses. Rigid gas permeable and scleral lenses may last one to three years with proper care, while custom soft lenses usually require replacement every six months to one year. We provide a specific replacement schedule based on your lens type, wearing habits, and how well the lenses maintain their shape and clarity.
Replace your lenses sooner if they become scratched, warped, or develop deposits that cleaning cannot remove. Wearing damaged or degraded lenses compromises both vision and eye health. We track your lens age during follow-up visits and let you know when it is time to order replacements. Regular replacement ensures you continue to experience the vision quality and comfort your custom lenses are designed to provide.
Follow-Up Care and Managing Your Custom Lenses
After you receive your final custom contact lenses, we schedule regular follow-up appointments to monitor your eye health and lens performance. Your first check-up typically occurs within one to two weeks of starting full-time wear. During these visits, we examine your corneas for any signs of stress, ensure adequate oxygen is reaching your eye tissues, and verify that your lenses remain properly fitted.
Ongoing monitoring is essential for long-term success with custom lenses. We recommend progress evaluations at intervals appropriate for your lens type and eye condition, often every three to six months initially, then annually once your wear is stable. These visits allow us to detect problems early and make adjustments before they affect your vision or comfort.
Some variation in comfort is normal as you adapt to custom contact lenses, but persistent or increasing discomfort requires evaluation. If your lenses feel uncomfortable after the initial adaptation period, they may need adjustment. Vision changes can indicate that your prescription has shifted, your lenses have deposited or warped, or your eye condition has progressed.
- Contact our office if discomfort persists beyond the expected adaptation period
- Report any redness, pain, light sensitivity, or discharge promptly
- Note if your vision becomes blurry or fluctuates throughout the day
- Keep track of when symptoms occur and what activities make them better or worse
- If you experience midday fogging with scleral lenses, consider a midday reservoir refresh, verify fill solution, and discuss ocular surface treatment with your provider
- Use only lubricating drops that are approved for use with your lens type
- Bring your lenses, case, and solutions to follow-up visits to review your care routine
Your eyes and vision can change over time, sometimes requiring lens modifications or complete refitting. Conditions like keratoconus may progress, prescriptions can shift, and corneal shape can evolve after surgery or with age. When changes occur, we reassess your eyes and determine whether minor parameter adjustments will suffice or if you need entirely new custom lenses.
Refitting follows a similar process to your initial fitting, with updated measurements and trial lenses. We compare current findings to your baseline data to understand how your eyes have changed. Most adjustments are straightforward, but significant changes may require exploring different lens designs or materials to maintain optimal vision and eye health.
Achieving lasting success with custom contact lenses depends on consistent wear and care habits, regular professional monitoring, and open communication with our eye care team. Most patients who follow recommended practices enjoy years of clear, comfortable vision with their custom lenses. Your commitment to proper lens hygiene, wearing schedules, and routine check-ups directly influences your long-term outcomes.
We partner with you throughout your custom lens journey, adjusting our recommendations as your needs evolve. Maintaining realistic expectations helps as well, understanding that custom lenses require more initial investment of time and effort than standard contacts but deliver vision that may not be achievable any other way. Many patients find that custom lenses dramatically improve their quality of life.
Certain symptoms indicate potential serious problems that require urgent evaluation. Remove your contact lenses immediately and contact our office if you experience sudden vision loss, severe eye pain, intense light sensitivity, or significant redness. Discharge, especially if green or yellow, may signal an infection requiring prompt treatment.
- Sudden decrease in vision that does not improve after removing your lenses
- Severe pain or feeling like something is stuck in your eye
- Intense redness or bloodshot appearance that worsens over hours
- Thick discharge, crusting, or mattering of your eyelids
- Flashes of light, new floaters, or shadows in your peripheral vision
- A new white or gray spot on the clear surface of your eye
- Severe pain out of proportion to exam findings or inability to open the eye
Frequently Asked Questions
Insurance coverage for custom contact lenses varies widely depending on your specific plan and the medical necessity of the lenses. Many vision insurance plans provide a contact lens allowance that can be applied toward custom lenses, though it may not cover the full cost since custom designs typically cost more than standard contacts. Medical insurance may cover custom lenses when they are medically necessary to treat conditions like keratoconus or corneal irregularity following disease or surgery. We can help you understand your benefits and provide documentation for insurance claims.
Custom gas permeable and scleral lenses generally last much longer than standard soft contact lenses, often between one and three years with excellent care. Custom soft lenses typically require replacement every six months to one year, similar to or slightly longer than standard soft lenses depending on the material and design. The longer lifespan of rigid custom lenses can make them more cost-effective over time despite their higher initial price. Your specific replacement schedule depends on your lens type, how well you care for them, and how quickly they accumulate deposits or show wear.
Yes, you can alternate between wearing your custom contact lenses and glasses, and many patients do so based on their daily activities and comfort. However, some eye conditions like keratoconus may not be fully correctable with glasses, making custom contacts essential for functional vision during certain tasks. If you wear orthokeratology lenses that temporarily reshape your cornea overnight, your glasses prescription may not provide clear vision during the day. We help you maintain an up-to-date glasses prescription as a backup option even if you primarily wear custom contacts.
No. You should never swim, use hot tubs, or shower while wearing contact lenses. Water exposure significantly increases the risk of serious eye infection, including Acanthamoeba keratitis, which can cause permanent vision loss. Remove your lenses before any water activity and reinsert them with sterile products afterward. If your lenses are accidentally exposed to water, remove them immediately, disinfect or replace them as directed by our office, and contact us if you develop pain, redness, or vision changes.
Whether you need custom lenses long-term depends entirely on your underlying eye condition and vision needs. Progressive conditions like keratoconus may require custom lenses indefinitely, though the condition often stabilizes in middle age. If you need custom lenses due to post-surgical irregularity, your cornea is unlikely to change, making custom lenses a permanent solution. Some patients try custom lenses temporarily while exploring other options like corneal cross-linking or surgical interventions. We monitor your condition regularly and discuss whether your custom lens need is likely temporary or ongoing.
Custom contact lenses are safe for daily wear when fitted properly, worn according to the prescribed schedule, and cared for with appropriate hygiene practices. Modern contact lens safety emphasizes adequate oxygen transmission, proper lens movement or clearance, and excellent care compliance. Modern custom lens materials and designs prioritize corneal health, and many patients wear custom lenses successfully for decades. The key to safety is following our wearing instructions, maintaining meticulous lens hygiene, attending all scheduled follow-up appointments, and reporting any problems promptly.
Finding the right custom lens fit can be challenging for some patients, but we have many options to explore before concluding custom lenses will not work for you. Different lens types like switching from GP to scleral designs, trying various materials, or adjusting parameters in small increments can make a significant difference. Sometimes addressing underlying issues like dry eye, allergies, or eyelid problems improves lens tolerance. In rare cases where custom contacts remain unsuccessful despite exhaustive efforts, we discuss alternative vision correction options including specialized glasses or consulting with corneal specialists about surgical possibilities. Our goal is working persistently to find a solution that meets your vision needs.
