Cataracts

Cataract claims at the BVA are structurally different from most other conditions. The rating mechanics under DC 6027 and DC 6028 are straightforward: the cataract itself is not directly rated. The rating attaches to the visual impairment that results, measured under the impairment-of-central-visual-acuity tables at DC 6066. If the cataract has been removed surgically and replaced with an intraocular lens (the standard treatment), the aphakia rules at DC 6029 set a minimum rating floor.

The structural problem is service connection. Most cataracts are age-related, often referred to clinically as senile cataracts or nuclear sclerosis. Cataracts develop in roughly half of all adults over 75. The clinical reality is that a 70-year-old Vietnam-era veteran who develops cataracts has cataracts because they are 70 years old, not because of anything that happened during military service. The Board sees this pattern across most cataract claims at the BVA, and the result is the lowest grant rate in the vision cluster: roughly 20 percent across 500 BVA cataract cases in my dataset.

Cataracts are not on the Agent Orange presumptive list, the PACT Act burn-pit list, or the Camp Lejeune list. The radiogenic disease list at 38 CFR § 3.311 does include posterior subcapsular cataracts as a radiogenic condition, which opens a narrow lane for veterans with documented in-service ionizing radiation exposure. Beyond that lane, cataract claims succeed when there is documented in-service eye trauma, documented in-service exposure to specific carcinogens or chemicals known to accelerate cataract formation, or a successful secondary claim from a service-connected condition or its treatment (most commonly long-term corticosteroid use for a service-connected condition).

This page covers DC 6027 and DC 6028, the visual acuity rating tables, the aphakia minimum rating under DC 6029, the radiogenic posterior subcapsular cataract lane under § 3.311, the secondary cascade from steroid use, and what wins cataract claims at the Board.

TL;DR

• 500 cataract cases in my BVA dataset. The grant rate is roughly 20 percent, the lowest in the vision cluster.
• Cataracts are rated under DC 6027 (traumatic cataract) or DC 6028 (preoperative cataract, all others) in the eye chapter at 38 CFR § 4.79. Both codes direct the rater to rate on visual impairment under DC 6066 (impairment of central visual acuity).
• The cataract itself is not directly rated. The rating attaches to the visual impairment that results. A cataract that does not impair vision rates at 0 percent.
• DC 6029 (aphakia or pseudophakia) sets a minimum 30 percent rating when the cataract has been surgically removed (with or without intraocular lens replacement) if both eyes are affected and corrected visual acuity is less than 20/40 in both eyes.
• Cataracts are not on the Agent Orange presumptive list, the PACT Act burn-pit list, or the Camp Lejeune list.
• Posterior subcapsular cataracts are on the radiogenic disease list at 38 CFR § 3.311 for veterans with documented in-service ionizing radiation exposure. This is the only structural presumptive-like lane for cataract claims.
• The most common successful cataract claims involve documented in-service eye trauma, in-service exposure to ionizing radiation, or secondary cataract formation from corticosteroid treatment for a service-connected condition.
• The biggest obstacle for direct cataract claims is the age-related cataract pattern, which the Board treats as the default explanation when the in-service evidence does not clearly establish an alternative cause.

DC 6027 and DC 6028, the Two Cataract Codes

The eye chapter at 38 CFR § 4.79 has two diagnostic codes that cover cataracts directly:

DC 6027, traumatic cataract. This code applies to cataracts caused by direct eye trauma. The rating language directs the rater to "rate based on visual impairment" under the DC 6066 table for impairment of central visual acuity.

DC 6028, preoperative cataract, all others. This code applies to non-traumatic cataracts, including age-related (senile), congenital, and metabolic cataracts. The rating language similarly directs the rater to "rate based on visual impairment" under DC 6066.

Both codes share the same rating mechanism: the cataract itself is not rated, but the visual impairment that results is. The diagnostic code distinction matters for service-connection analysis (traumatic cataract from documented in-service eye trauma is structurally easier to grant than non-traumatic cataract requiring an alternative causation theory) but not for the rating once service connection is established.

The Visual Acuity Table at DC 6066

The DC 6066 table rates impairment of central visual acuity based on the best-corrected visual acuity in each eye. The table is a matrix: rows for one eye, columns for the other, with the rating at the intersection.

The relevant tiers, with both eyes' best-corrected acuity:

• 20/40 each: 0 percent
• 20/40 one eye, 20/50 to 20/70 other eye: 10 percent
• 20/40 one eye, 20/100 to 20/200 other eye: 20 to 30 percent depending on severity
• 20/50 each: 10 percent
• 20/70 each: 30 percent
• 20/100 each: 50 percent
• 20/200 each: 70 percent
• 5/200 each: 90 percent
• No light perception each (blindness): 100 percent

The critical concept is "best-corrected" visual acuity. The rating is based on the visual acuity achieved with the best available corrective lenses (eyeglasses, contact lenses, or intraocular lens after cataract surgery), not the uncorrected vision. A veteran with a dense cataract that drops uncorrected vision to 20/200 but corrects to 20/30 with eyeglasses or after surgery with an intraocular lens rates at 0 percent under the visual acuity table, because the best-corrected acuity is 20/30.

This is why modern cataract surgery typically resolves the rating issue. Standard cataract surgery removes the clouded natural lens and replaces it with an intraocular lens, and the post-operative best-corrected visual acuity is often 20/20 or 20/25. A veteran who undergoes successful cataract surgery and recovers to 20/25 vision in both eyes rates at 0 percent on the visual acuity table after surgery, even if the pre-operative vision was much worse.

DC 6029, Aphakia and Pseudophakia

DC 6029 (aphakia or pseudophakia, unilateral or bilateral) sets a minimum rating floor for veterans whose cataracts have been surgically removed. Aphakia is the absence of the natural lens (typically after cataract removal without intraocular lens replacement, which is now rare). Pseudophakia is the presence of an artificial intraocular lens after cataract removal (the standard modern treatment).

The rating language at DC 6029:

• Bilateral aphakia or pseudophakia: 30 percent minimum if both eyes have best-corrected visual acuity less than 20/40
• Unilateral aphakia or pseudophakia: rated based on impairment of central visual acuity under DC 6066

The 30 percent minimum for bilateral aphakia or pseudophakia is significant. It establishes a floor that applies even when the post-surgical visual acuity is reasonably good. For a veteran with bilateral cataract surgery resulting in 20/40 corrected vision in both eyes, the rating would be 0 percent under DC 6066 (visual acuity table) but 30 percent under DC 6029 (aphakia minimum). DC 6029 controls because it produces the higher rating.

The DC 6029 minimum applies only when both eyes are aphakic or pseudophakic. A veteran with cataract surgery on only one eye does not benefit from the bilateral minimum; the unilateral case is rated on visual acuity alone.

The Radiogenic Posterior Subcapsular Cataract Lane

Cataracts are not on the Agent Orange presumptive list. The Agent Orange presumptive conditions at 38 CFR § 3.309(e) are primarily cancers, neurological conditions, and certain metabolic conditions. Cataracts have been considered for inclusion through the periodic National Academy of Sciences review process but have not been added.

The exception is posterior subcapsular cataracts under the radiogenic disease framework at 38 CFR § 3.311. This regulation covers veterans with documented in-service exposure to ionizing radiation (atomic veterans, nuclear weapons testing participants, occupation of Hiroshima or Nagasaki, certain gaseous diffusion plant workers, and other defined populations).

Posterior subcapsular cataracts are specifically listed as a radiogenic disease at § 3.311(b)(2). For veterans with documented in-service radiation exposure who develop posterior subcapsular cataracts (a specific anatomical type of cataract that forms at the back of the lens, distinct from the more common nuclear or cortical age-related cataracts), the § 3.311 framework provides a procedural pathway.

The § 3.311 procedure requires VA to develop the case by obtaining a radiation dose estimate from the Defense Threat Reduction Agency, then forwarding the case to VA's Under Secretary for Benefits for review. The Under Secretary considers whether the cataract is "at least as likely as not" related to the exposure based on the dose estimate and the latency period. This is not a true presumption (the case still requires individual adjudication) but it provides a structured pathway that veterans without documented radiation exposure do not have.

The radiogenic lane covers a small population. Most cataract claims at the BVA do not involve documented radiation exposure, and the radiogenic pathway is unavailable for them.

Secondary Cataracts From Corticosteroid Use

The other significant pathway for cataract claims is secondary service connection from corticosteroid treatment. Long-term systemic corticosteroid use (oral prednisone, repeated steroid injections, or chronic inhaled steroids at high doses) is a well-established medical cause of posterior subcapsular cataract formation. The mechanism is documented in the ophthalmology and rheumatology literature.

For veterans with a service-connected condition that requires long-term corticosteroid treatment, secondary cataracts may be service-connected under 38 CFR § 3.310. The medical chain runs:

1. Service-connected condition (commonly rheumatoid arthritis, severe asthma, inflammatory bowel disease, lupus, or other conditions requiring steroid management)
2. Treatment of that condition with long-term corticosteroids
3. Development of posterior subcapsular cataracts as a known complication of the steroid treatment

The secondary claim requires:

• Documentation of the service-connected primary condition
• Documentation of the long-term corticosteroid treatment (treatment records showing the dose, duration, and route of administration)
• A medical opinion connecting the cataract formation to the corticosteroid use
• Ideally, ophthalmology documentation specifying posterior subcapsular cataracts as the cataract type (not nuclear or cortical, which are typically age-related)

The corticosteroid secondary lane produces meaningful results when the documentation supports it. The medical mechanism is well-accepted, the cataract type is distinctive on ophthalmology examination, and the timing of cataract development relative to the corticosteroid treatment is usually traceable.

What Trips Up Most Cataract Claims

The dominant denial pattern at the BVA is the age-related cataract problem. Cataracts develop in roughly half of all adults over 75 as a normal part of aging. When a veteran files a direct cataract claim without documented in-service trauma, radiation exposure, or a secondary corticosteroid pathway, the Board's default analysis treats the cataract as age-related.

The challenge for the veteran is to produce evidence that the cataract is not age-related, or that an in-service event accelerated its formation beyond what would have happened with aging alone. The medical opinion has to address:

• Whether the cataract type (nuclear, cortical, posterior subcapsular) is consistent with an alternative etiology
• Whether any in-service exposure or event is a known cause of cataract formation
• Whether the timing of cataract development is consistent with that alternative cause rather than with normal age-related onset

Generic nexus opinions that say "the cataract is at least as likely as not related to service" without engaging with the age-related alternative explanation tend to fail. The opinion needs to address the alternative explanation directly.

For veterans with documented in-service eye trauma, the analysis is structurally easier. Traumatic cataracts are a recognized clinical entity, and the medical literature supports the causation chain from blunt or penetrating eye trauma to subsequent cataract formation. The cataract may develop months or years after the trauma. When the in-service trauma is documented in the service treatment records, the claim turns on whether the current cataract is the traumatic kind or whether age has also added to it.

What Wins Cataract Claims at the Board

A few patterns I see consistently in granted cataract cases.

Documented in-service eye trauma. Service treatment records showing an eye injury (often from a blast injury, penetrating trauma, vehicle accident, or weapon recoil). The trauma documentation establishes the underlying mechanism for the DC 6027 traumatic cataract code. Subsequent ophthalmology documentation linking the current cataract to the documented in-service trauma supports the grant.

Documented in-service ionizing radiation exposure, with posterior subcapsular cataracts. The radiogenic disease pathway under § 3.311 requires documented exposure (atomic veteran, nuclear weapons testing, gaseous diffusion plant work, occupation of Hiroshima or Nagasaki). Posterior subcapsular cataract type on ophthalmology examination supports the pathway specifically.

Secondary corticosteroid pathway with strong documentation. Service-connected primary condition (most commonly rheumatoid arthritis, severe asthma, lupus, or inflammatory bowel disease), documented long-term corticosteroid treatment, posterior subcapsular cataract type on ophthalmology examination, and a medical opinion connecting the steroid use to the cataract formation.

Visual acuity measurements that clear the rating tiers. Best-corrected visual acuity in both eyes that fits the DC 6066 table at a ratable level. Pre-surgical measurements often show severe impairment that drops to 0 percent after successful surgery. The rating analysis is typically performed on the most recent visual acuity findings.

Bilateral aphakia or pseudophakia for the 30 percent minimum. When both eyes have undergone cataract surgery and the best-corrected vision is less than 20/40 in both eyes, the DC 6029 minimum of 30 percent applies. This is often the highest rating veterans with bilateral cataract surgery can achieve when the post-surgical visual acuity is otherwise good.

Strong nexus opinion that addresses the age-related alternative. The medical opinion needs to engage with the age-related cataract pattern directly and explain why an alternative etiology is more likely. Generic opinions fail; opinions that specifically address the cataract type, the timing, and the alternative causation tend to succeed.

Bottom Line

Cataracts are rated under 38 CFR § 4.79 DC 6027 (traumatic) or DC 6028 (all others). Both codes direct the rater to rate on visual impairment under DC 6066, not on the cataract itself. DC 6029 sets a 30 percent minimum for bilateral aphakia or pseudophakia when corrected vision is less than 20/40 in both eyes. In my BVA dataset of 500 cases, the grant rate is roughly 20 percent, the lowest in the vision cluster. Most denials come down to the age-related cataract problem: the Board treats cataracts as age-related by default when the in-service evidence does not establish an alternative cause. The pathways to a granted cataract claim run through documented in-service eye trauma (DC 6027), documented in-service ionizing radiation exposure with posterior subcapsular cataract type (§ 3.311), or secondary service connection from long-term corticosteroid treatment for a service-connected condition. Modern cataract surgery typically resolves the rating to 0 or 30 percent because best-corrected post-surgical vision is usually good, with the 30 percent minimum applying only when both eyes have undergone surgery and post-operative best-corrected vision is less than 20/40 in both eyes.

Methodology and Limitations

• Data source: 38 CFR § 4.79 (eye chapter), DC 6027 (traumatic cataract), DC 6028 (preoperative cataract), DC 6029 (aphakia or pseudophakia), DC 6066 (impairment of central visual acuity), 38 CFR § 3.311 (radiogenic diseases), 38 CFR § 3.310 (secondary service connection), and Claim Raven's analysis of BVA decisions tagged with cataracts as the primary condition.
• Sample size: 500 BVA decisions involving cataracts as the primary condition, with a grant rate of roughly 20 percent. Subcategory breakdowns (connection-type splits, denial-reason splits, rating-tier distributions) are summarized in directional terms rather than precise counts because the underlying classifications continue to be refined as the dataset is reprocessed.
• Limitations: The dataset captures BVA-level decisions. Cataract claims granted at the regional office without appeal are not in the sample. The age-related cataract pattern is the dominant denial reason and reflects medical reality (cataracts are highly prevalent in adults over 65) more than any procedural problem in the rating system. The radiogenic disease pathway under § 3.311 requires the cataract to be the posterior subcapsular type specifically; some BVA cases involve ophthalmology documentation that does not clearly distinguish cataract types, complicating the analysis. The corticosteroid secondary pathway requires documentation of long-term systemic steroid use; veterans with shorter steroid courses or intermittent use often face skepticism about the causal chain. These observations describe BVA patterns and are not predictions of individual outcomes. Claim Raven is data analysis, not legal, medical, or VA-accredited advice.
