Corneal Cross-Linking for Keratoconus at Washington Eye Institute
Keratoconus is a progressive condition where the cornea thins and bulges into an irregular cone shape, causing blurred vision and ghosting. Washington Eye Institute offers advanced corneal cross-linking (CXL) to stabilize the cornea and help halt progression. Our team is led by a fellowship-trained cornea specialist, Joseph Mekhail, MD. Our optometric team — which includes Maryland's 2025 Young Optometrist of the Year — provides comprehensive keratoconus management and specialty contact lens care, including hard, scleral, and hybrid options.

What Is Keratoconus and Why Does Treatment Matter?
Keratoconus is a progressive condition in which the cornea, the clear front surface of your eye, gradually thins and bulges outward into an irregular cone-like shape. This distortion changes the way light enters your eye, causing blurred vision, ghosting around lights, and increasing astigmatism that may shift with each new prescription. If you have noticed that your glasses or contact lenses need frequent updates, keratoconus may be the cause. Increasingly distorted vision in one or both eyes can point to a thinning, unstable cornea. The American Academy of Ophthalmology recognizes corneal cross-linking as the standard of care for progressive keratoconus.
Our keratoconus care team includes Rajini Seevaratnam, OD, who provides advanced contact lens and keratoconus management, and Diana Chu, OD, Maryland's 2025 Young Optometrist of the Year, who specializes in specialty contact lens fitting for irregular corneas and coordinates peri-surgical care for cross-linking patients. Washington Eye Institute is led by Dr. Michael Summerfield, MD, a board-certified ophthalmologist and Georgetown University/Washington Hospital Center Residency Program Director.

Specialized Keratoconus Care
From initial diagnosis through post-procedure scleral contact lens fitting, our team provides coordinated care for every stage of your keratoconus journey.
Is Cross-Linking Right for Your Cornea?
Corneal cross-linking is recommended for patients with documented progression of keratoconus or other corneal ectatic disorders (conditions that cause the cornea to thin and bulge). If your corneal topography shows increasing steepening, or your prescription is changing rapidly, you may be a strong candidate for this keratoconus treatment option.
The best outcomes are typically achieved when cross-linking is performed early in the course of progression. Our specialist will review your diagnostic imaging to determine whether CXL can help stabilize your cornea and preserve your current level of vision. For patients with advanced or late-stage keratoconus where the cornea has thinned significantly or scarred beyond the benefit of cross-linking, Washington Eye Institute also offers corneal transplantation as an alternative treatment pathway.
Early intervention with cross-linking can make the difference between stable vision and continued corneal deterioration. Keratoconus surgery through CXL is most effective when progression is caught early.

Epithelium-Off Cross-Linking for Keratoconus
Epithelium-off corneal cross-linking is the FDA-approved standard of care for progressive keratoconus. During the procedure, the epithelium (the thin outer layer of the cornea) is gently removed to allow riboflavin drops to fully saturate the corneal tissue. Your surgeon then applies UV-A light to activate the riboflavin and create new collagen bonds that strengthen the cornea.
This proven approach halts or significantly slows corneal steepening in the vast majority of treated patients, helping to preserve vision and reduce the risk of needing a corneal transplant in the future.
How Cross-Linking Treatment Works
Evaluation & Imaging
Dr. Mekhail maps your cornea with topography and pachymetry to confirm CXL candidacy and plan treatment. Procedures are performed at our Washington Eye Surgery Center in Rockville, Maryland.
Epithelial Removal
Your surgeon applies numbing drops, then gently removes the thin outer layer of the cornea (epithelium) to allow riboflavin to penetrate the tissue.
Riboflavin Application
Your surgeon applies riboflavin drops to the cornea at regular intervals to saturate the tissue before UV exposure.
UV-A Light Exposure
Controlled UV-A light activates the riboflavin, creating new collagen cross-links that strengthen and stabilize the cornea.
Recovery & What to Expect After Cross-Linking
Days 1–3: Initial Healing
A bandage contact lens protects the cornea while the epithelium heals. Most patients experience some discomfort and light sensitivity during this time. Dr. Mekhail prescribes drops and may recommend over-the-counter pain relief.
Week 1: Epithelial Healing
The epithelium typically closes within five to seven days. Your bandage contact lens is usually removed at your first follow-up visit. Avoid rubbing your eyes and follow your drop regimen closely.
Weeks 2–8: Visual Stabilization
Vision may fluctuate as the cornea heals. Most patients notice gradual improvement over several weeks. Avoid swimming and contact sports during this period.
Months 3–6: Final Assessment
Dr. Mekhail performs follow-up topography to confirm corneal stabilization. Once measurements are stable, your contact lens prescription can be reassessed and updated.
Accelerated Cross-Linking Protocol
Accelerated CXL delivers a higher intensity of UV-A light over a shorter treatment time while achieving similar corneal strengthening results. This protocol reduces time in the procedure chair and is well-suited for patients who may benefit from a faster treatment session.
Post-CXL Scleral Lens Fitting
After your cornea has stabilized from cross-linking, custom scleral contact lenses can provide clear, comfortable vision by vaulting over the irregular corneal surface and creating a smooth optical interface. We also offer specialty hard contact lenses and hybrid contact lenses that combine rigid and soft lens technology for patients who prefer an alternative to full scleral designs.
Signs You May Need Cross-Linking
If you are experiencing any of the following, your keratoconus may be progressing and a cross-linking evaluation should be considered.
Advanced CXL Technology
Our practice uses the latest diagnostic and treatment technology to deliver precise, effective corneal cross-linking results.
UV-A Light Delivery System
Precision UV-A irradiation with precisely calibrated exposure levels for consistent corneal strengthening. The system delivers uniform light distribution across the treatment zone to help ensure even collagen cross-link formation.
Riboflavin Solution Application
FDA-approved riboflavin formulations optimized for corneal tissue saturation. The solution is applied at carefully timed intervals to prepare the cornea for UV-A activation and effective collagen bonding.
Corneal Pachymetry Monitoring
Real-time corneal thickness measurement ensures safe treatment parameters throughout the procedure. Continuous monitoring allows your surgeon to confirm that the cornea maintains adequate thickness during riboflavin saturation and UV-A exposure.
Corneal Topography Mapping
High-resolution surface mapping tracks corneal shape changes before and after cross-linking. This detailed imaging helps Dr. Mekhail identify progression patterns, plan treatment, and verify stabilization at follow-up visits.
Frequently Asked Questions
Does corneal cross-linking hurt?
Dr. Mekhail applies numbing drops throughout the procedure, so most patients do not feel pain during cross-linking itself. Discomfort typically begins after the numbing wears off and lasts for the first few days while the epithelial surface heals. Dr. Mekhail will prescribe drops and may recommend over-the-counter pain relief to keep you comfortable during this period.
How long does the cross-linking procedure take?
The full procedure takes approximately one hour, including preparation of the corneal surface, application of riboflavin drops, and ultraviolet light exposure. It is performed in an outpatient setting at our Washington Eye Surgery Center in Rockville, Maryland, and you will go home the same day. Plan to have a family member or friend available to drive you after the appointment.
Will I still need contact lenses after cross-linking?
In most cases, yes. Cross-linking stabilizes the cornea to prevent further shape changes, but it does not reverse the irregular curvature that has already developed. Many patients continue to wear scleral contact lenses or other specialty lenses to achieve their best possible vision after the cornea has healed and stabilized. Your prescription can be reassessed once your corneal measurements are stable.
What are the risks of corneal cross-linking?
Corneal cross-linking has a well-established safety profile. The most common side effects include temporary corneal haze, light sensitivity, and mild discomfort during the first few days of healing. As with any procedure, there is a small risk of infection, which is minimized by following your post-operative drop regimen. Some patients experience temporary changes in vision clarity during the healing period. Dr. Mekhail will discuss all potential risks and benefits with you during your consultation.
At what age is cross-linking typically recommended?
Cross-linking is most commonly recommended for patients in their teens and twenties because keratoconus tends to progress most during these years. However, any patient with documented corneal progression may be a candidate regardless of age. Joseph Mekhail, MD evaluates each patient individually based on topography changes, corneal thickness, and overall eye health.
Can cross-linking be performed on both eyes at the same time?
Dr. Mekhail typically performs cross-linking on one eye at a time. This approach allows you to maintain functional vision in the untreated eye during the initial recovery period and reduces the risk of bilateral infection. The second eye is usually scheduled after the first eye has healed sufficiently, often within a few weeks. Dr. Mekhail will discuss the timing that works best for your situation.
Is corneal cross-linking covered by insurance?
Many insurance plans now cover FDA-approved epithelium-off corneal cross-linking for progressive keratoconus. Coverage varies by plan, so we recommend contacting your insurance provider before your procedure.
