Contact Lenses After LASIK
Why Some Patients Need Contact Lenses After LASIK
LASIK surgery aims to correct your entire prescription, but sometimes a small amount of nearsightedness, farsightedness, or astigmatism remains. This residual error can happen if the laser treatment did not fully reshape the cornea to the planned correction or if your eye responded differently than expected during healing.
Even a minor prescription can affect daily activities like reading street signs or working on a computer. Contact lenses can provide the extra correction needed to bring your vision to a comfortable level without requiring another surgery.
Your vision may change months or years after LASIK as your cornea continues to heal and settle into its new shape. Some patients experience a gradual shift back toward their original prescription, a process called regression.
- Risk of regression is higher with high hyperopic or high myopic corrections
- Vision can shift with hormonal changes such as pregnancy
- Early lens changes inside the eye can alter refraction over time
- Corneal healing can vary from person to person
- Contact lenses offer a non-surgical way to manage these vision shifts
LASIK corrects distance vision and astigmatism but does not prevent presbyopia, the natural loss of near focusing ability that typically begins in your early to mid-40s. After LASIK, you may still need reading glasses or contact lenses for close-up tasks like reading menus or using your phone.
We may recommend multifocal contact lenses or monovision correction to help you see clearly at all distances without needing separate reading glasses.
In rare cases, the cornea may develop an irregular shape after LASIK, causing distorted vision that glasses cannot fully correct. Post-LASIK ectasia is a condition where the cornea becomes progressively thinner and bulges forward, though this complication is uncommon with modern screening techniques.
Specialty contact lenses can vault over the irregular corneal surface and create a smooth optical surface, often restoring clear and comfortable vision even when the cornea shape is not ideal.
If post-LASIK ectasia is suspected or progressing, corneal collagen crosslinking may be recommended to stabilize the cornea. Specialty contact lenses can then be used to optimize vision.
While many patients are candidates for a LASIK enhancement to fine-tune their vision, some cannot safely undergo another laser procedure. Your cornea may be too thin for additional reshaping, or other eye health factors may make surgery too risky.
- Insufficient corneal thickness prevents safe laser treatment
- Dry eye symptoms may worsen with additional surgery
- Certain corneal irregularities increase surgical risks
- Contact lenses can provide effective correction without surgical risks
- Depending on your age and eye health, alternatives like PRK enhancement, a phakic IOL, or lens-based surgery may be considered. Your surgeon will review these options if appropriate.
Signs You May Benefit from Contact Lenses Post-LASIK
If you notice that road signs, television screens, or distant objects appear fuzzy several weeks or months after your LASIK procedure, you may have residual refractive error. Blurred near vision when reading or using a smartphone can also indicate a prescription change or the onset of presbyopia.
Contact lenses can often improve clarity to meet your visual needs and improve your quality of life during daily activities.
Some patients experience increased glare, halos around lights, or reduced contrast sensitivity in low-light conditions after LASIK. These visual disturbances can make nighttime driving challenging or uncomfortable.
- Halos and starbursts around headlights and street lights
- Decreased ability to see in dim lighting
- Difficulty judging distances at night
- Specialized contact lenses can sometimes reduce these symptoms
- Avoid night driving if glare or halos feel unsafe until your eye doctor evaluates you
Straining to focus on your computer screen, books, or other close work can lead to tired eyes, headaches, and discomfort by the end of the day. These symptoms often signal that your eyes are working harder than they should to compensate for uncorrected vision.
Correcting even a small prescription with contact lenses can dramatically reduce eye strain and help you feel more comfortable throughout your workday.
If your vision seems clear at times but blurry at others, dry eye or corneal surface irregularities may be the cause. Fluctuating vision can also result from incomplete healing or changes in your tear film quality after surgery.
We will evaluate the underlying cause and determine whether contact lenses, dry eye treatment, or both will provide the most stable and comfortable vision for you. We may recommend pausing contact lens wear until the ocular surface is optimized to stabilize your vision.
You should schedule an appointment if you notice any changes in your vision after LASIK, especially if they interfere with your daily activities or safety. Early evaluation allows us to identify the cause and recommend appropriate solutions before symptoms worsen.
- New or worsening blurriness that does not improve with blinking
- Visual disturbances that affect your ability to drive safely
- Persistent eye strain or discomfort
- Any sudden vision changes or eye pain
- Difficulty performing tasks you could do comfortably before
- Do not wear or reinsert contact lenses if your eyes are red, painful, or sensitive to light until you are examined
How We Diagnose Vision Changes After LASIK
Our eye doctor will begin with a thorough examination to assess your overall eye health and measure how well you see at various distances. Visual acuity testing helps us determine the extent of any vision loss and whether it affects one or both eyes.
We will also review your LASIK surgery details, healing timeline, and any symptoms you have experienced to understand the full picture of your vision changes.
Corneal topography creates a detailed map of your cornea's surface shape, revealing any irregularities or asymmetries that may be causing vision problems. We also measure corneal thickness to ensure your eye structure is healthy and stable after surgery.
- Identifies areas of irregular curvature or steepening
- Detects early signs of post-LASIK ectasia
- Helps us select the most appropriate contact lens design
- Provides baseline measurements for future comparisons
- Tomography evaluates the back surface of the cornea for earlier ectasia detection
- Epithelial thickness mapping can help differentiate true regression from surface remodeling
Wavefront aberrometry measures higher-order aberrations that can cause glare, halos, and reduced contrast after LASIK. These data guide lens design choices and set realistic expectations.
- Quantifies optical distortions beyond standard glasses prescriptions
- Helps determine whether rigid or specialty lenses may reduce symptoms
We perform a careful refraction to measure your exact prescription, including any nearsightedness, farsightedness, or astigmatism. This test determines which lens powers will give you the clearest vision and guides our contact lens recommendations.
Post-LASIK eyes sometimes require more precise refraction techniques because the corneal shape differs from that of eyes that have not had surgery. We may perform cycloplegic refraction if internal lens changes are suspected. Because post-LASIK corneas are more oblate, we use techniques tailored to your corneal profile.
We assess the health of your corneal surface and the quality of your tear film, as LASIK can sometimes affect tear production and distribution. Dry eye is common after LASIK and can impact both your comfort and your success with contact lenses.
- Measurement of tear production and stability
- Examination of the corneal surface for dryness or damage
- Assessment of meibomian gland function
- Evaluation of inflammation or other healing issues
- Advanced testing such as tear osmolarity and MMP-9 may be used to assess inflammation
- Meibography can evaluate the oil glands that support a stable tear film
- We often optimize the ocular surface before fitting contact lenses to improve comfort and vision
Contact Lens Options for Post-LASIK Eyes
If you have a small residual prescription and a relatively regular corneal shape, standard soft contact lenses may provide excellent vision and comfort. These lenses are often the most convenient and affordable option for post-LASIK patients with straightforward vision needs.
We will ensure the lens fits properly on your altered corneal shape and provides stable vision throughout the day before finalizing your prescription.
- Daily disposable lenses often improve comfort and reduce infection risk
- Toric soft lenses can correct residual astigmatism
- We will verify stable centration and rotation on your post-refractive cornea
Rigid gas permeable lenses, or RGP lenses, create a smooth refractive surface over an irregular cornea and can correct vision that glasses cannot. These lenses allow excellent oxygen flow to the cornea and often provide sharper vision than soft lenses for patients with corneal irregularities.
- Vault over irregular areas to create a uniform optical surface
- Maintain their shape on the eye for consistent vision
- Allow your cornea to breathe with high oxygen permeability
- May require an adaptation period for comfort
- A piggyback system (a soft lens under an RGP) can improve comfort for sensitive eyes
Scleral lenses are larger specialty lenses that rest on the white part of your eye rather than on the cornea itself. They vault over the entire corneal surface and are filled with fluid, making them ideal for patients with significant corneal irregularities, severe dry eye, or post-LASIK ectasia.
These lenses often provide excellent comfort and vision quality for patients who have not succeeded with other contact lens types, and they protect the corneal surface throughout the day.
Scleral lenses should be made from high oxygen permeability materials and fit to allow adequate tear exchange.
- Fill lenses only with preservative-free sterile saline before insertion
- We will monitor for midday fogging and adjust fit and care if needed
Hybrid contact lenses feature a rigid gas permeable center for clear vision surrounded by a soft lens skirt for comfort. This design can be an excellent compromise for patients who need the optical quality of a rigid lens but prefer the initial comfort of a soft lens.
We may recommend hybrid lenses if you have moderate corneal irregularity or if you have tried RGP lenses but found them too uncomfortable for all-day wear.
Multifocal contact lenses contain different prescription zones to help you see clearly at all distances, addressing both any residual refractive error and age-related near vision loss. These lenses can reduce or eliminate your need for reading glasses after LASIK.
- Simultaneous vision designs with multiple focal points
- Available in both soft and rigid gas permeable materials
- May require a short adjustment period as your brain adapts
- Allow you to read, work on computers, and see distance clearly
- Monovision can reduce depth perception. We often trial this in-office to confirm tolerance.
Custom wavefront-guided lenses are specialized designs that address higher-order aberrations. Availability is limited and typically found in specialty clinics, often using scleral platforms.
We will discuss whether this option is appropriate for your symptoms and eye measurements. Outcomes vary, and not all aberrations are fully correctable in real-world wear.
Caring for Your Eyes with Post-LASIK Contact Lenses
Learning to insert and remove your contact lenses correctly is essential for maintaining eye health and lens performance. Our eye doctor will teach you the proper techniques during your fitting appointment and ensure you feel confident handling your lenses before you leave.
- Always wash and dry your hands thoroughly before touching lenses
- Use the insertion method appropriate for your specific lens type
- Remove lenses gently to avoid damaging your cornea
- Never force a lens onto your eye if it does not feel right
- Do not sleep in contact lenses unless your eye doctor specifically prescribes it
- Do not swim, use a hot tub, or shower while wearing contact lenses
- Avoid rubbing your eyes while lenses are on and after removal
Proper lens care prevents infections, protein buildup, and other complications that can harm your eyes or reduce your wearing comfort. Use only the cleaning solutions our eye doctor recommends, as some products are not compatible with post-LASIK eyes or certain lens materials.
Replace your lens case every three months and never use tap water or saliva to rinse your lenses, as these can introduce harmful microorganisms that cause serious eye infections.
- Rub and rinse lenses nightly if your lens type requires it, and never top off old solution
- Hydrogen peroxide care systems may be recommended for some lens types
- Scleral lenses require preservative-free sterile saline for filling, not multipurpose solution
Dry eye is common after LASIK and can affect contact lens comfort and wearing time. We may recommend preservative-free artificial tears, prescription medications, or other treatments to improve your tear film quality before or during contact lens wear.
- Use lubricating drops as directed throughout the day
- Take breaks from screen time to reduce evaporation
- Consider a humidifier in dry environments
- Discuss prescription dry eye treatments if symptoms persist
- Some lens designs help retain moisture better than others
- Punctal plugs can help retain tears
- Lid hygiene and thermal therapies can improve oil quality
- Prescription options include cyclosporine or lifitegrast eye drops and varenicline nasal spray
- We often treat dry eye before or along with contact lens fitting
Follow the replacement schedule we prescribe for your specific lenses, whether daily disposable, bi-weekly, or monthly. Wearing lenses beyond their recommended lifespan increases your risk of infections and reduces vision quality and comfort.
We will also provide guidance on daily wearing time, as overwearing contact lenses can deprive your cornea of oxygen and lead to complications, especially in post-LASIK eyes that may already have some corneal changes. Avoid overnight wear unless explicitly prescribed, as it increases infection risk.
Remove your contact lenses immediately and contact our office if you experience sudden vision loss, severe eye pain, intense redness, or discharge. These symptoms can indicate serious conditions like corneal ulcers or infections that require urgent treatment.
- Sudden decrease in vision that does not improve after lens removal
- Severe pain or feeling that something is stuck in your eye
- Significant redness, especially if concentrated in one area
- Unusual discharge or excessive tearing
- Increased sensitivity to light beyond normal adaptation
- Do not reinsert contact lenses until you are cleared by your eye doctor
- A white spot on the cornea or a focal area of severe pain can be a sign of a corneal ulcer
Frequently Asked Questions
No, you will need to wait until your cornea has healed sufficiently and your vision has stabilized, which typically takes at least three months after surgery. Most patients wait several weeks to a few months, typically 4 to 12 weeks, until the cornea is stable. Your surgeon will advise the timing. Therapeutic bandage or scleral lenses may be used earlier if medically indicated.
When properly fitted and cared for, contact lenses are safe for post-LASIK eyes and do not damage the cornea when properly fitted and cared for. When properly fitted and cared for they are safe, but sleeping in lenses or exposing them to water increases the risk of corneal infection. Follow the care instructions precisely.
Standard soft lenses for post-LASIK eyes usually cost about the same as regular contact lenses. However, specialty lenses like sclerals or custom rigid gas permeable lenses are more expensive due to their complex design and fitting process, though many patients find the improved vision well worth the investment. Specialty fittings usually involve more visits and custom designs, which can add cost. Coverage varies by plan.
Yes, many patients alternate between glasses and contact lenses depending on their activities and comfort level. Your eyeglass prescription may differ slightly from your contact lens prescription due to the distance between the lens and your eye, so we will provide both if you plan to use each option.
The duration varies depending on why you need lenses. If presbyopia is the cause, you will likely need vision correction for near tasks for the rest of your life. If regression or residual error is the issue, your prescription may remain stable for years, or you might eventually become a candidate for an enhancement procedure if your cornea allows. If age-related lens changes or cataracts develop, lens-based surgery later in life can also address refractive error.
