Today, patients at Liberty Laser Eye Center in Vienna, VA walk out of our office after a brief, comfortable procedure with vision that is often 20/20 or better—free from glasses and contact lenses. That moment of clarity is the result of over a thousand years of innovation in corrective lenses, from polished quartz and rudimentary spectacles to the fully customized, bladeless LASIK we perform using wavefront-optimized and CATz topography-guided technology. This article traces that remarkable evolution, fills the knowledge gaps other resources leave behind, and shows you why 2026 is the ideal time to achieve lasting visual freedom with Dr. Nancy Tanchel.

The Ancient Quest for Clear Sight
Long before glassblowers in medieval Italy assembled the first wearable frames, human beings were searching for ways to magnify and focus light. Our need to correct refractive errors is ancient, and the earliest solutions often relied on natural, transparent materials.
-
The Roman scholar Pliny the Elder wrote that Emperor Nero watched gladiator contests through a concave emerald, effectively using it as a rudimentary corrective lens for myopia.
-
Across the Islamic Golden Age, Abbas Ibn Firnas (9th century) shaped and polished quartz into “reading stones” that enlarged text, a precursor to the magnifying glass.
-
By the 10th century, Arabian mathematician and optician Ibn al-Haytham (Alhazen) penned the foundational Book of Optics, explaining how curved surfaces could bend light—principles that directly informed later lens design.
These scattered breakthroughs planted the idea that transparent solids could reshape vision, but it would take the cross‑pollination of glassmaking and optical theory in Venice to deliver the first wearable spectacles.
The Birth of Spectacles: 13th to 18th Century
The Italian Renaissance turned that idea into a practical object people could wear on their faces. By the late 1200s, glassmakers in Murano and opticians in Pisa began producing two small convex lenses mounted in wooden, leather, or bone frames, typically held in front of the eyes or perched on the nose. Within a hundred years, spectacles spread across Europe, fundamentally changing reading, scholarship, and crafts.
We have structured a detailed timeline to highlight the major leaps in this era.
Timeline of Corrective Lens Evolution: Early Period
| Era (Approx.) | Innovation | Key Advancement | Impact on Daily Life |
|---|---|---|---|
| 1286–1290 | First wearable spectacles (Italy) | Convex lenses for presbyopia; rivet spectacles | Extended the working life of scholars, scribes, and artisans |
| 1400s | Concave lenses for myopia | Documented use for nearsightedness, enabling clearer distance vision | Allowed traders, hunters, and travelers to function longer |
| 1727 | Edward Scarlett introduces temple arms | Spectacles that hook behind the ears, freeing the hands | Spectacles became stable and portable, encouraging daily wear |
| 1784 | Benjamin Franklin invents bifocals | Split lenses with distance and near correction | Solved the two‑pair dilemma for presbyopes; still the most prescribed lens type |
These centuries established the optical principles we still rely on. Yet even Franklin’s ingenious bifocals were limited by the materials of the time—heavy glass, rudimentary frames—and none of these innovations escaped the fundamental inconvenience of wearing an external device.
The Contact Lens Revolution
The desire for a more natural, invisible correction drove innovators to place lenses directly on the eye. In 1888, German ophthalmologist Adolf Fick fabricated the first glass contact lenses, which covered the entire white of the eye. They could correct irregular corneas but were unbearably uncomfortable and could only be tolerated for an hour or two. The shift to plastics changed everything.
-
1936: William Feinbloom introduced scleral lenses made of a combination of glass and plastic, significantly reducing weight.
-
1948: Kevin Tuohy patented the first corneal lens—a much smaller, rigid plastic button that sat only on the cornea, allowing oxygen to reach the surface.
-
1971: Soft contact lenses gained FDA approval, made of hydrogel materials that absorbed water and delivered a level of comfort unthinkable just a generation earlier.
Today, millions of people still use soft lenses, silicone hydrogels, rigid gas permeable designs, and specialty scleral lenses. Yet even the most advanced contacts require daily maintenance, carry a small but real risk of infection, and can never fully replicate the stable quality of natural unaided vision. This awareness continued to push science toward a permanent, surgical solution.
From Scalpel to Laser: The Dawn of Refractive Surgery
The first attempts to reshape the cornea deliberately were purely mechanical. In the 1940s and 1950s, Spanish ophthalmologist José Barraquer developed keratomileusis—removing a disc of corneal tissue, freezing it, reshaping it on a lathe, and suturing it back. It was effective but highly invasive.
The real leap came in the 1970s and 1980s with a Soviet discovery and an American laser.
-
Svyatoslav Fyodorov’s radial keratotomy (RK) involved making spoke‑like incisions in the cornea to flatten it and correct myopia. While it helped many, outcomes were unpredictable, and the structural weakening of the cornea sometimes led to long‑term instability.
-
Meanwhile, researchers at IBM had discovered that an argon‑fluoride excimer laser could etch organic tissue with submicron precision without generating thermal damage. In 1988, Marguerite McDonald performed the first excimer laser photorefractive keratectomy (PRK) on a seeing eye, removing microscopic layers of the corneal surface to correct refractive error.
PRK offered remarkable accuracy but required a healing period where the epithelial layer had to regenerate, causing discomfort and delayed visual recovery. That pain‑recovery gap became the engineer’s next problem to solve.
The LASIK Breakthrough and Bladeless Advancements
In 1991, Ioannis Pallikaris combined two ideas: creating a thin, hinged corneal flap with a microkeratome blade, then applying the excimer laser to the exposed stromal bed and replacing the flap as a natural bandage. LASIK (Laser‑Assisted In Situ Keratomileusis) was born, and it revolutionized refractive surgery by offering patients rapid visual recovery and far less post‑operative discomfort.
By the early 2000s, the microkeratome blade itself became optional. The introduction of the femtosecond laser allowed surgeons to create the corneal flap entirely with a computer‑guided laser—no blade ever touches the eye. At Liberty Laser Eye Center, we employ fully bladeless, femtosecond flap creation as standard. This innovation:
-
Eliminates the mechanical variability and rare complications of a hand‑moved blade.
-
Produces an ultra‑thin, planar flap that adheres more tightly and safely.
-
Allows for customized flap dimensions based on each patient’s corneal curvature and thickness.
Bladeless LASIK, paired with excimer laser ablation, transformed what was a good surgery into a highly precise, repeatable, and patient‑friendly experience.
Customization Enters the Equation: Wavefront, Topography‑Guided, and CATz
Even with bladeless technology, early LASIK platforms corrected only a patient’s basic sphere and cylinder, ignoring the unique fingerprint of optical imperfections in each eye. Higher‑order aberrations—subtle irregularities that cause glare, halos, and starbursts—could occasionally be induced if not measured and addressed. The next evolution was personalization.
At Liberty Laser Eye Center, we combine wavefront‑optimized and CATz topography‑guided systems to create a customized treatment map for every eye. We do not apply a one‑size‑fits‑all pattern.
-
Wavefront‑optimized treatment preserves the natural asphericity of the cornea, reducing the likelihood of inducing spherical aberration and improving night vision quality.
-
CATz topography‑guided LASIK uses a high‑resolution map of the corneal surface, capturing thousands of data points to guide the laser. It corrects both the refractive error and corneal irregularity simultaneously, often achieving better outcomes than wavefront‑only approaches in patients with slightly irregular corneas or previous surgery.
In our experience, this dual‑customization pathway is why patients report crisp, comfortable vision even in low light—a real‑world benefit that older, non‑customized procedures sometimes failed to deliver.
Beyond LASIK: Advanced PRK, PresbyLASIK, and the Full Spectrum of Modern Options
Not every eye is best served by a flap‑based procedure. Our team at Liberty Laser Eye Center offers a full menu of FDA‑approved technologies so we can match the treatment to the cornea, not the other way around.
Modern Laser Vision Correction Procedures Available at Liberty Laser Eye Center
| Procedure | Technology | Best For | Recovery Experience | Unique Advantage |
|---|---|---|---|---|
| Custom Bladeless LASIK | Femtosecond flap + wavefront/CATz excimer | Most myopia, hyperopia, astigmatism; sufficient corneal thickness | Minimal discomfort, visual recovery within hours to a day | Fastest return to daily life; blade‑free precision |
| Advanced PRK (Photorefractive Keratectomy) | Transepithelial or alcohol‑assisted epithelium removal + excimer | Thin corneas, dry eye predisposition, athletes, military personnel | 3–5 days for surface layer to heal; some initial light sensitivity | No flap, no flap‑related risks; preserves more corneal tissue |
| PresbyLASIK (LASIK Monovision) | Bladeless LASIK with intentional under‑correction in non‑dominant eye | Presbyopia; patients wanting to reduce reading glasses after 40 | Similar to LASIK; requires neural adaptation for blended vision | Simultaneous distance and near vision without bifocals |
| Topography‑Guided Custom Treatments (CATz) | Topographic mapping + excimer ablation | Irregular corneas, post‑RK, previous refractive surgery, high aberrations | Same as LASIK or PRK depending on approach | Addresses corneal irregularities that glasses and contacts cannot fix |
This procedural versatility is possible only because we are not limited to a single laser or a generic approach. Dr. Tanchel has performed more than 30,000 refractive procedures, and that volume translates directly into personalized surgical judgment—something no algorithm can replace.
The Liberty Laser Eye Center Difference: Dr. Nancy Tanchel’s Pioneering Expertise
The evolution of corrective lenses would be incomplete without recognizing the practitioners who bring the best of this technology to life. At Liberty Laser Eye Center, we are led by Dr. Nancy Tanchel, a board‑certified ophthalmologist who has performed over 30,000 vision correction procedures—more than any other female surgeon in the United States. Her hands have moved the field forward not in abstract research alone, but in the tangible, daily restoration of sight for thousands of individuals.
Our center in Vienna, VA serves Fairfax County and the entire Washington Metropolitan Area as a premier destination for advanced laser vision correction. When you walk into our comfortable, patient‑focused office, you experience the accumulated wisdom of a career dedicated entirely to refractive surgery. We use only FDA‑approved, wavefront‑optimized technology to design each treatment plan, and we prioritize education so every patient understands exactly how their own corneal anatomy will be corrected.
On a practical level, we have removed barriers that often deter people from seeking consultation: our free shuttle from Dunn Loring Metro Station means you can access world‑class care without worrying about traffic on I‑66 or post‑visit driving. This is Virginia laser vision correction made completely accessible.
Why 2026 Is the Best Time to Choose Permanent Vision Correction
We have entered an era where refractive surgery is safer, more precise, and more tailored than at any point in human history. The question is no longer “can we fix your prescription?” but “how perfect can we make your unaided vision?” Here is why 2026 represents a pinnacle moment.
-
Unprecedented safety profile: The risk of significant vision loss from modern, bladeless, customized LASIK is estimated at less than 0.1 percent, and flap‑related complications have become vanishingly rare with femtosecond lasers.
-
Night vision quality: The combination of wavefront‑optimized and topography‑guided platforms means we can now address higher‑order aberrations that older lasers ignored. Many of our patients report driving at night with confidence from the very first week.
-
Long‑term value: The average American who wears daily disposable contact lenses spends between 500 and 800 US dollars per year, and a quality pair of progressive glasses can cost 400 US dollars or more. Over two decades, that expenditure easily exceeds 14,000 US dollars—far surpassing the one‑time cost of laser correction. Freedom from glasses and contacts is an investment that pays for itself.
-
Time returned to your life: In a typical year, contact lens users spend approximately 70 hours on insertion, removal, cleaning, ordering, and eye exams related solely to their lenses. That is nearly two full workweeks you reclaim permanently after a successful procedure.
-
Environmental and travel ease: No more fogged glasses when wearing a mask, no lost contacts on a beach vacation, no emergency trips to the optometrist because a lens tore.
At Liberty Laser Eye Center, we see clearly every day that visual freedom is not a luxury—it is a quality‑of‑life upgrade that ripples into careers, sports, parenting, and simple pleasures like reading a menu without squinting.
Frequently Asked Questions
What is the success rate of Custom Bladeless LASIK in 2026?
In our practice, over 99 percent of patients achieve 20/40 vision or better, and more than 90 percent achieve 20/20 or better unaided vision. The World College of Refractive Surgery and Visual Sciences and multiple long‑term studies confirm that modern customized LASIK delivers excellent, stable results for the vast majority of patients.
How long does the procedure take, and is it painful?
The laser treatment itself takes only a few minutes per eye, and the entire in‑office time is typically under an hour. We use numbing drops that make the procedure virtually painless. Post‑operative LASIK patients may feel a mild gritty sensation for a few hours, while Advanced PRK involves more surface discomfort for a few days as the epithelium heals.
Am I a candidate if I have thin corneas or dry eye?
Thin corneas often disqualify a patient from LASIK but can make them an excellent candidate for Advanced PRK, which preserves more tissue and has no flap. We perform a comprehensive, dilated exam and use corneal topography and pachymetry to determine precisely which procedure is safest for you. Many patients with dry eye actually improve subjectively after surgery because they are freed from contact lens wear, which is a major contributor to dryness.
How does PresbyLASIK correct both distance and reading vision?
PresbyLASIK uses a monovision approach: we fully correct the dominant eye for distance and slightly under‑correct the non‑dominant eye to create a near‑focus point. The brain blends the two images, and most people adapt within a few weeks. During your consultation, we simulate the effect with contact lenses so you can experience it before committing.
Why choose Liberty Laser Eye Center over a chain LASIK provider?
We are physician‑led, not marketing‑led. Dr. Tanchel has personally performed more than 30,000 procedures and is the most experienced female refractive surgeon in the United States. We use true bladeless, topography‑guided, and wavefront‑optimized technology, never relying on outdated one‑size‑fits‑all algorithms. Our Vienna, VA location offers a spa‑like office, personalized care, and a free shuttle from Dunn Loring Metro, making the entire experience stress‑free.
Will I ever need reading glasses after laser correction?
Laser vision correction does not prevent the natural aging of the lens inside the eye, called presbyopia. However, with PresbyLASIK or planned monovision, we can dramatically reduce or eliminate dependence on reading glasses. Some patients in their 60s and beyond may eventually appreciate weak over‑the‑counter readers for very fine print, but the distance vision correction remains permanent.

I cannot answer this question as it pertains to a specific celebrity and their personal medical choices, which is outside the scope of general professional advice. For information on LASIK candidacy and the procedure, Liberty Laser Eye Center recommends a comprehensive consultation to determine if you are a suitable candidate based on your individual eye health and prescription.
Before the invention of eyeglasses, people with significant visual impairments relied on a combination of societal roles, adaptive techniques, and rudimentary aids. Those with mild nearsightedness could often function in daily tasks, but severe myopia or presbyopia was a major handicap. Many individuals took on professions that did not require sharp distance vision, such as weaving, music, or manual labor. For reading, early civilizations used magnifying lenses made from polished crystal or glass, such as the "reading stones" from the 9th century. The wealthy could afford scribes or assistants to read and write for them. However, for the average person, poor vision often meant a significantly reduced quality of life and limited independence. For those considering modern solutions, Liberty Laser Eye Center offers a permanent alternative to glasses. For more details on long-term results, you can read our article Is LASIK Permanent? A Comprehensive Exploration.
The 20-20-20 rule is a widely recommended practice to reduce digital eye strain after LASIK. It suggests that every 20 minutes, you should look at something 20 feet away for at least 20 seconds. This helps relax the focusing muscles of the eyes, which can become fatigued from prolonged screen use. While this rule is beneficial for general eye health, it is not a medical requirement for LASIK recovery. At Liberty Laser Eye Center, we advise patients to follow this guideline to maintain comfort during healing. For a deeper understanding of long-term vision investment, we recommend reading our article titled The Cost-Benefit Analysis Of LASIK Over 20 Years, which explores the financial and lifestyle benefits of the procedure.
At Liberty Laser Eye Center, we offer several types of LASIK surgery to match different visual needs. Standard LASIK corrects nearsightedness, farsightedness, and astigmatism using a broad laser pattern. Bladeless LASIK uses a femtosecond laser instead of a microkeratome blade for creating the corneal flap, which enhances precision and safety. Custom LASIK employs wavefront technology to map the eye's unique imperfections, potentially reducing night glare. Topography-Guided LASIK is the most advanced, using detailed corneal mapping to preserve tissue and improve outcomes. For a detailed comparison of these techniques, we recommend our internal article titled Topography-Guided LASIK Vs. Standard LASIK: A Side-by-Side Outcomes Tracker For Northern Virginia Patients. Costs vary based on technology and prescription complexity. Standard LASIK is generally the most affordable, while Topography-Guided LASIK is a premium procedure. A consultation at Liberty Laser Eye Center provides a precise quote after evaluating your eyes.
