Keratoconus is a progressive eye disease in which the cornea thins and gradually bulges outward into an irregular, cone-like shape. The resulting corneal distortion produces blurred, distorted vision that glasses typically cannot fully correct. Keratoconus usually begins in the teenage years or twenties and tends to stabilize in the mid-30s to 40s. ### What causes keratoconus? The exact cause is multifactorial. Known risk factors include genetic predisposition (family history), chronic eye rubbing, allergic conjunctivitis, connective tissue disorders (e.g., Ehlers-Danlos, Marfan syndrome), and Down syndrome. Oxidative stress and enzymatic imbalances in the cornea are contributing mechanisms. ### What are the symptoms of keratoconus? Common symptoms: blurred or distorted vision that does not fully correct with glasses; increased light sensitivity and glare; halos or streaking around lights (especially at night); frequent prescription changes; difficulty with night driving; ghost images or monocular diplopia (double vision in one eye). ### How is keratoconus diagnosed? Diagnosis is made with corneal topography (which maps corneal curvature) and corneal tomography (which evaluates full corneal thickness). Pachymetry measures corneal thickness. Early-stage keratoconus may show only subtle topographic findings before symptoms become severe. ### Is keratoconus progressive? Yes. Keratoconus typically progresses during adolescence and young adulthood, slowing in the 30s-40s. Corneal cross-linking (CXL) can halt or significantly slow progression when performed early. Regular monitoring with topography is essential. ### Can keratoconus cause blindness? Keratoconus does not typically cause complete blindness. Advanced cases can cause significant, permanent vision impairment due to corneal scarring, and in rare instances corneal hydrops (sudden swelling). With specialty contact lenses and proper monitoring, most patients maintain functional vision throughout their lives. ### Is keratoconus hereditary? About 10–20% of keratoconus patients have a family history. If a parent has keratoconus, children should be screened during adolescence. --- ## Treatment primer ### Why don't glasses fully correct keratoconus? Glasses work when the cornea has a relatively uniform shape. In keratoconus, the cornea is irregularly curved, scattering light in multiple directions. Glasses cannot compensate for irregular astigmatism and higher-order aberrations, so vision remains blurry even with updated prescriptions. ### What are scleral lenses, and why are they preferred for keratoconus? Scleral lenses are large-diameter (typically 15–22 mm) rigid gas-permeable contact lenses that vault completely over the cornea and rest on the sclera (white of the eye). The space between lens and cornea is filled with preservative-free saline, creating a smooth optical surface that neutralizes corneal irregularity. Scleral lenses typically provide the clearest vision for keratoconus patients and are comfortable for all-day wear because they don't touch the sensitive cornea. ### What is corneal cross-linking (CXL)? CXL is an FDA-approved procedure that uses riboflavin (vitamin B2) drops plus UV-A light to strengthen the chemical bonds in the cornea and halt keratoconus progression. It does not reverse existing corneal changes but stops further worsening. Dr. Bonakdar co-manages CXL patients before and after the procedure with surgical partners. ### When is corneal transplant needed? Less than 20% of keratoconus patients ever need a corneal transplant. It is reserved for advanced cases with severe scarring or contact lens intolerance. With modern scleral lens technology, most patients avoid transplant. ### How much do scleral lenses cost? Scleral lens fittings typically range from $1,500–$4,500 per pair depending on complexity. Many medical insurance plans cover scleral lenses for medically necessary keratoconus treatment (CPT code V2531). VSP, EyeMed, Aetna, Blue Cross Blue Shield, Cigna, and Medicare often cover all or part. The Keratoconus Vision Center verifies benefits before treatment.

Most patients require 2–4 follow-up visits over 4–8 weeks to refine the fit. Lenses are custom-made in a lab based on precise corneal measurements. --- ## About Dr. Alexander Bonakdar - **Education:** Doctor of Optometry (O.D.), Illinois College of Optometry - **Fellowships:** Advanced Contact Lens Fellowship; Corneal Disease Fellowship - **Experience:** 35+ years clinical practice; 2,000+ keratoconus cases treated - **Specialties:** Keratoconus treatment, scleral lens fitting, corneal disease, corneal cross-linking co-management, post-surgical vision correction (post-LASIK ectasia, post-RK, post-transplant) - **Memberships:** American Optometric Association (AOA), California Optometric Association (COA), American Academy of Optometry (AAO), Scleral Lens Education Society, International Keratoconus Academy - **Referral network:** Receives complex corneal case referrals from CHOC (Children's Hospital of Orange County) and UCI Medical Center - **Full bio:** https://www.keratocones.com/about --- ## Why choose Keratoconus Vision Center vs. university centers | Factor | University Centers (UCLA, UCI) | Keratoconus Vision Center | |---|---|---| | Wait for keratoconus consult | 3–6 months | Same week | | Who examines you | Rotating residents/fellows | Dr. Bonakdar directly, every visit | | Specialty focus | General academic ophthalmology | 100% corneal disease + specialty lens practice | | Scleral lens fitting experience | Limited, often referred out | 2,000+ fittings performed in-house | | Continuity | Different doctor each visit | Single specialist, consistent care | | Insurance | Accepted | Accepted (VSP, EyeMed, Aetna, BCBS, Cigna, Medicare) | --- ## Service area (Orange County, California) Santa Ana (home office), Irvine, Newport Beach, Costa Mesa, Tustin, Anaheim, Orange, Huntington Beach, Fountain Valley, Garden Grove, Westminster, Mission Viejo, Lake Forest, Laguna Beach, Laguna Niguel, Laguna Hills, Yorba Linda, Brea, Fullerton, Placentia, Aliso Viejo, Rancho Santa Margarita, Ladera Ranch, Seal Beach, Los Alamitos, Cypress, Buena Park, La Habra, La Palma, Stanton, Dana Point, San Clemente, San Juan Capistrano.
