A Radial Keratotomy Patient’s Poem: From Blurred Vision to Renewed Hope

When an RK Patient’s Gratitude Becomes Poetry

Some patients describe their vision journey in a testimonial. Others write a review. One of our dear patients, a radial keratotomy patient who traveled from Oregon to Gulani Vision Institute in Jacksonville, Florida, expressed her experience through something far more personal—a poem.

Her words reflect the frustration shared by countless RK patients who have repeatedly heard:

“There’s no fix for your vision that’s blurred.”

But Cynthia’s poem also captures the philosophy that has guided Dr. Arun Gulani throughout his career:

“But Gulani says ‘No! That isn’t so!’”

For Dr. Gulani, this poem represents more than appreciation. It represents why complex radial keratotomy patients should not automatically be dismissed, generalized, or labeled “not a candidate.”

Every RK eye is different. Every patient’s visual demands are different. Therefore, every solution must be designed individually.

What Is Radial Keratotomy?

Radial keratotomy, commonly called RK, was an early refractive surgical procedure used primarily during the 1970s, 1980s, and 1990s to correct nearsightedness. Surgeons created spoke-like incisions in the cornea to flatten its central curvature and reduce myopia.

Although many patients initially enjoyed freedom from glasses, RK eyes can change over time. Decades later, some patients experience:

• Progressive farsightedness or hyperopic shift
• Fluctuating vision throughout the day
• Irregular astigmatism
• Glare, halos, starbursts, and ghost images
• Poor night vision
• Loss of contrast sensitivity
• Double or multiple images
• Corneal instability
• RK incision-related scarring
• Increasing dependence on glasses or contact lenses
• Cataract formation
• Difficulty obtaining consistent measurements
• Poor outcomes following conventional cataract surgery
• Continued visual dissatisfaction despite being told they see “20/20”

An RK patient may see differently in the morning than in the evening. Vision can change with hydration, altitude, lighting, pupil size, corneal biomechanics, and even the pressure exerted by the eyelids.

This is why an RK eye cannot be evaluated or treated like a routine eye.

Why Are RK Eyes So Difficult to Measure?

Traditional vision measurements frequently describe refractive error using three familiar categories:

• Nearsightedness
• Farsightedness
• Astigmatism

But an RK cornea may contain a much more complicated optical profile.

Its astigmatism may be regular, irregular, asymmetric, with-the-rule, against-the-rule, oblique, or influenced by higher-order aberrations such as coma, trefoil, and secondary astigmatism. The apparent axis on one diagnostic test may not agree with the axis measured by refraction, topography, tomography, aberrometry, keratometry, or biometry.

These measurements are not necessarily “wrong.” They may simply be recording different components of an optically complex and dynamically changing cornea.

Dr. Gulani has compared this dilemma to trying to measure an 11-foot-tall person with a conventional tape measure—especially when that person is also bent and twisted. The measuring instrument may function perfectly, but the subject no longer fits conventional assumptions.

Every RK Pattern Creates a Different Optical Puzzle

Not all radial keratotomy surgeries were performed in the same way. Patients may have:

• Four, eight, twelve, sixteen, twenty, or more radial incisions
• Repeated or enhanced RK procedures
• Astigmatic keratotomy incisions
• Hexagonal keratotomy
• Limbal relaxing incisions
• Previous LASIK or PRK
• Corneal scraping or superficial keratectomy
• Corneal scars
• Keratoconus or ectasia
• Prior cataract surgery
• Monofocal, toric, multifocal, EDOF, or adjustable lens implants
• YAG laser capsulotomy
• Previous lens exchanges
• Piggyback lens implants
• Corneal transplants
• Scleral or rigid contact lens dependence

Each incision pattern alters corneal structure and optics differently. Even two eyes belonging to the same patient may require completely different treatment plans.

The number of RK cuts alone does not determine whether an eye can be helped. The surgeon must also study their depth, location, symmetry, healing response, scar pattern, optical-zone size, corneal thickness, curvature, stability, lens status, retinal potential, and relationship to the patient’s visual symptoms.

The Gulani Philosophy: Do Not Chase a Number—Design the Vision

Dr. Gulani approaches complex RK eyes by first determining the source of the patient’s visual limitation.

Is the primary obstacle located in the cornea? The natural lens? A previously implanted lens? The ocular surface? The retina? Or is it a combination of several optical problems?

This is the foundation of his “Ingredient versus Recipe” philosophy.

A laser, toric lens, monofocal lens, adjustable lens, pinhole lens, corneal segment, or other technology is merely an ingredient. The outcome depends on selecting the correct ingredients, placing them in the correct sequence, and designing an individualized optical recipe for that particular eye.

The goal is not to force every patient into one procedure. The goal is to determine the best possible path toward that patient’s visual potential.

The Importance of Refraction in RK Patients

While advanced diagnostic technologies are valuable, Dr. Gulani emphasizes the importance of listening to the patient and carefully studying their refraction.

An RK corneal map may appear dramatic, but the patient does not see a map—they see through their optical system.

For that reason, Dr. Gulani studies how the patient responds to lenses, how the refractive endpoint behaves, how vision changes with axis and power adjustments, and whether the blur is correctable, irregular, fluctuating, or cataract-related.

In certain cases, the refractive axis can be interpreted as a vector representing the displacement of functional vision through the cornea’s most optically influential region. This information may help guide the selection and orientation of a toric lens or the planning of a staged laser procedure, even when conventional measurements do not appear to agree.

The purpose is not merely to make diagnostic tests look better. It is to improve how the patient actually sees.

Cataract Surgery After Radial Keratotomy

Cataract surgery in an RK eye is among the most challenging situations in refractive cataract surgery.

Previous RK changes the relationship between the front and back surfaces of the cornea, making conventional lens-power formulas less predictable. Small inaccuracies can produce substantial refractive surprises. Additionally, the cornea itself may continue to fluctuate after an otherwise technically successful cataract operation.

Potential challenges include:

• Difficulty calculating lens implant power
• Hyperopic or myopic refractive surprises
• Uncertain astigmatism magnitude and axis
• Incision instability
• Irregular corneal optics
• Existing glare, halos, and ghosting
• Variable measurements on different days
• Reduced predictability with premium lens technology
• Worsening dissatisfaction after an anatomically successful surgery

This is why Dr. Gulani describes cataract surgery in an RK patient as refractive surgery—not simply cataract removal.

The lens implant may be selected as an intentional optical “landing point,” creating a more favorable platform for a later corneal procedure. In selected eyes, a toric lens may be used strategically even when topography, refraction, and biometry do not display the conventional agreement expected in an untouched cornea.

The first stage does not always represent the final destination. It may prepare the eye for the next precisely planned step.

Can Toric Lens Implants Be Used in RK Eyes?

A toric lens can sometimes play an important role in an RK treatment plan, but it should not be chosen from one measurement alone.

The surgeon must consider:

• Manifest and cycloplegic refraction
• Corneal topography and tomography
• Total corneal astigmatism
• Keratometry and biometry
• Regular versus irregular astigmatism
• Higher-order aberrations
• Incision architecture
• Corneal scars
• Visual-axis behavior
• Lens position
• The fellow eye
• The possibility of staged corneal correction

In Dr. Gulani’s approach, the toric lens may reduce a dominant astigmatic vector or deliberately position the eye at an optically manageable endpoint. A subsequent LaZrPlastique® procedure may then address residual refractive error and what patients often describe as visual “noise.”

This staged strategy differs from treating the toric lens as a stand-alone answer.

LaZrPlastique® for Selected RK Patients

Many RK patients have been told that laser vision correction is impossible because their corneas have already been cut, flattened, scarred, or made irregular.

Dr. Gulani’s LaZrPlastique® approach is not conventional LASIK and does not require creating another corneal flap. It is a customized, refraction-driven surface laser methodology designed to address selected complex corneal and refractive conditions.

Depending on the eye, LaZrPlastique® may be considered for:

• Residual nearsightedness
• Residual farsightedness
• Astigmatism
• Irregular optics
• Refractive surprises after cataract surgery
• Vision problems following prior RK enhancements
• Selected corneal scars
• Previous LASIK or PRK combined with RK
• Visual dissatisfaction following premium lens implantation

Not every RK patient needs laser treatment, and not every cornea is suitable for the same approach. The decision depends on careful examination, diagnostic agreement, refractive behavior, corneal thickness, structural safety, lens status, and realistic visual potential.

Must an Unhappy Cataract Patient Exchange the Lens Implant?

Not necessarily.

Some RK patients arrive with poor vision following cataract surgery elsewhere believing their lens implant must be removed because their vision remains blurred after cataract surgery. In selected cases, however, the implanted lens may be well positioned and anatomically stable. The remaining visual problem may arise primarily from the cornea, residual refractive error, irregular astigmatism, ocular surface disease, or a combination of factors.

When appropriate, Dr. Gulani may use corneal laser techniques to improve the optical system without exchanging the existing lens implant.

Avoiding unnecessary intraocular surgery may be particularly valuable in complex eyes, but every case must be evaluated individually.

Other Procedures That May Be Considered

Because RK cases vary so widely, possible strategies may include:

• Customized cataract surgery
• Monofocal lens implantation
• Toric lens implantation
• Pinhole or small-aperture lens technology
• Piggyback lens implantation
• Lens exchange in carefully selected cases
• LaZrPlastique®
• Corneoplastique® techniques
• Selective RK incision suturing
• Astigmatic management
• Ocular-surface treatment
• YAG laser treatment when clinically indicated
• Contact lenses or scleral lenses
• Corneal transplantation in advanced cases
• A staged combination of corneal and lens-based procedures

Scleral lenses can provide meaningful vision for some patients. Dr. Gulani sometimes compares them to a “Superman suit”—they may provide excellent function while being worn, but they do not permanently alter the underlying optics. For patients who cannot tolerate them or want to explore surgical options, a detailed evaluation may reveal additional possibilities.

Why Crosslinking Is Not Automatically the Answer

Corneal crosslinking can be valuable for documented progressive ectasia, but it is not a universal treatment for every RK patient with fluctuating or irregular vision.

Crosslinking is intended primarily to stabilize corneal tissue; it does not automatically correct refractive error, remove irregular astigmatism, or restore clear unaided vision. In an already distorted cornea, stabilization without an optical strategy may preserve the existing abnormality.

Therefore, structural stability and visual rehabilitation should be considered separately and then integrated into a thoughtful sequence.

Treating the Patient, Not Merely the Corneal Map

In Cynthia’s poem, she writes:

“You spend hours on each patient’s file.”

That line captures an essential part of complex RK care.

The patient’s occupation, hobbies, driving requirements, reading needs, night-vision demands, tolerance for glasses, previous surgical history, and goals must all influence the plan.

A pilot, surgeon, law-enforcement officer, hunter, artist, athlete, or professional driver may have visual demands that cannot be summarized by a Snellen acuity measurement alone.

Similarly, a patient who measures 20/20 but experiences ghosting, starbursts, glare, image splitting, or fluctuating focus may remain profoundly dissatisfied. Visual quality matters—not only visual quantity.

Why Staging Can Be a Sign of Precision

RK patients sometimes expect one operation to correct every optical problem immediately. But when the cornea, lens, and astigmatism all contribute to the blur, staging may offer greater control.

A carefully designed sequence might involve:

1. Improving the ocular surface.
2. Determining whether the cataract or cornea is the dominant limitation.
3. Performing customized cataract surgery to establish an optical foundation.
4. Allowing the eye and refraction to stabilize.
5. Measuring the residual visual error.
6. Using LaZrPlastique® or another appropriate technique to refine the outcome.

Staging is not indecision. In complex eyes, it can be a deliberate strategy that allows each procedure to prepare the eye for the next.

There Is No Universal RK Procedure

The most important message for RK patients is that there is no single “RK correction.”

One patient may benefit from surface laser correction. Another may require cataract surgery with a strategically selected lens. Another may need sutures, corneal segments, ocular-surface rehabilitation, a pinhole lens, or a carefully staged combination.

Some eyes may be best served by nonsurgical visual correction.

The responsible question is not, “What procedure fixes RK?”

It is: “What combination and sequence best addresses the unique anatomy, optics, and visual goals of this particular RK patient?”

From Oregon to Jacksonville—and From Gratitude to Poetry

Like many patients from around the world, Cynthia traveled from Oregon carrying a difficult RK history and the uncertainty familiar to many patients who have already sought multiple opinions.

She later transformed her experience into poetry—writing about a surgeon’s mission, the staff’s compassion, the importance of studying every case, and the belief that complicated patients deserve thoughtful consideration.

Her most powerful message may be this:

“I’m not going to bluff.
My case was tough,
Dr. Gulani and staff earned a toast!”

Her poem is personal, spontaneous, and entirely her own. But its meaning reaches beyond one patient.

It speaks for RK patients who have been told their eyes are too irregular, too unpredictable, too surgically altered, or too complicated to consider further.

A Message to Radial Keratotomy Patients

Previous RK does not guarantee that additional surgery is appropriate. It also should not automatically mean that nothing can be done.

A comprehensive evaluation can help determine:

• Why the vision is blurred
• Whether the problem is corneal, lenticular, retinal, or combined
• Whether the eye is structurally stable
• Whether the visual error is measurable and reproducible
• Whether a surgical or nonsurgical option is reasonable
• Whether treatment should be performed in one step or multiple stages
• What level of vision can realistically be expected

For Dr. Gulani, complex RK care begins by refusing to reduce a unique eye to a generic label.

Cynthia’s poem says it beautifully:

“He works late at night
To bring people sight.
Their lives will forever be changed!”
