How AI Search Is Recommending LASIK Eye Surgery: Monthly Trends

Executive Summary

September 2026 brought the first significant category movements the benchmark has recorded for LASIK Eye Surgery, and they were all downward. Two brands, TLC Laser Eye Centers and ClearSight LASIK, are flagged as significant decliners on valid recommendation coverage, the share of qualified AI answers in which a brand is recommended. No brand rose significantly. The category leader held steady.

LasikPlus remains the category leader at 21.6% valid recommendation coverage in September 2026, effectively flat against its 21.8% baseline in July 2026. The gap to the second-place brand has widened: The LASIK Vision Institute fell to 16.1% in September 2026, down from 22.6% in July 2026, leaving LasikPlus with a 5.5-point lead. In July 2026, the two brands were separated by just 0.8 points, with The LASIK Vision Institute narrowly ahead.

The strongest upward mover is Mann Eye Institute, which climbed from 2.4% in July 2026 to 3.5% in September 2026, a two-month streak of gains. The sharpest percentage-point decliners are The LASIK Vision Institute, down from 22.6% to 16.1%, and TLC Laser Eye Centers, down from 13.3% to 7.9%. The benchmark classifies TLC Laser Eye Centers and ClearSight LASIK, which fell to 0.0%, as significant decliners; The LASIK Vision Institute's decline, while the largest in absolute terms, falls within its normal range of variation.

Against the prior month, the category was stable in the aggregate, with no significant movement from August 2026 to September 2026. The significant moves it recorded are measured from the July 2026 baseline to the current month, and they reflect a broad thinning of recommendation coverage across the upper and middle tiers of the tracked field.

Each monthly run begins with 587 prompt-surface observations (452 unique questions) in September 2026 across the benchmark's defined AI/search surface universe, down from 800 observations (634 unique questions) in August 2026 and 438 observations (335 unique questions) in July 2026. Of those, 587 mentioned a tracked brand or competitor in September 2026; 406 were relevant and 181 were irrelevant, compared with 395 relevant and 163 irrelevant in August 2026. The public metrics use the 254 observations that survive both qualification stages in September 2026, down from 279 in August 2026 and 248 in July 2026.

Key Findings

Benchmark Context

The September 2026 report draws on a collection universe smaller than August 2026 but with a similar qualification pattern. The table separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

These research-stage counts show the funnel from raw collection to the public benchmark. The table that follows summarizes benchmark-wide metrics for the baseline and current months.

Benchmark-Level Metrics

August 2026 was the intermediate month, when LasikPlus reached 25.4% and The LASIK Vision Institute held 21.9%. The current month's narrowing of the field reflects The LASIK Vision Institute and TLC Laser Eye Centers falling back from their August levels, not a gain by any brand in the upper tier.

AI Recommendation Trend

The Two-Brand Top Tier Has Narrowed into a Clearer Single-Leader Structure

LasikPlus is the only tracked brand above 20% valid recommendation coverage in September 2026. In July 2026, The LASIK Vision Institute led LasikPlus by 0.8 points; by September 2026, LasikPlus led by 5.5 points, as The LASIK Vision Institute fell 6.5 points from baseline while LasikPlus held roughly steady. The LASIK Vision Institute remains in second place despite that decline.

September 2026 produced two significant declines from the July 2026 baseline, for TLC Laser Eye Centers and ClearSight LASIK. No brand exceeded normal month-to-month variation in the upward direction. The category-level thinning came from a combination of several downward moves concentrated in the upper and middle tiers, with The LASIK Vision Institute, TLC Laser Eye Centers, and NVISION Eye Centers all falling while Mann Eye Institute and Kraff Eye Institute made modest gains.

What Changed This Month

TLC Laser Eye Centers: A Significant Decline on Coverage and Presence

TLC Laser Eye Centers' valid recommendation coverage moved from 13.3% in July 2026 to 7.9% in September 2026, a 5.4-point decline the benchmark flags as significant. The brand held 20 valid recommendations in September 2026, down from 33 in July 2026.

TLC's raw mention presence moved from 41.1% to 26.4%, down 14.7 points. Its top-three rate fell from 9.7% to 5.9%, down 3.8 points, while its rank-one rate held at 0.8%.

TLC's presence declined far more in percentage-point terms than its valid recommendation coverage, meaning the brand was mentioned less often across AI answers while also losing share of the recommendations that remained. The benchmark does not establish whether the presence decline drove the coverage decline or whether separate forces moved both.

Highest-priority diagnostic: Which surfaces and prompt types account for TLC's presence decline, and in the prompts where TLC lost recommendation credit, which competitor or competitors appeared in its place?

ClearSight LASIK: From Marginal to No Valid Recommendations

ClearSight LASIK's valid recommendation coverage fell from 1.6% in July 2026 to 0.0% in September 2026, down 1.6 points and significant. The brand recorded zero valid recommendations in September 2026, down from 4 in July 2026.

ClearSight's raw mention presence moved from 3.2% to 2.8%, down 0.4 points, and its top-three rate fell from 1.2% to 0.0%. The brand went from 3 rank-one recommendations in July 2026 to none in September 2026.

The combination of a small presence decline and a complete loss of recommendation credit means ClearSight LASIK appeared in several AI answers in September 2026 but was not recommended in any of them. With only 7 raw mentions in the current month, small-count caution applies to any interpretation.

Highest-priority diagnostic: In the prompts where ClearSight LASIK still appears but is not recommended, which provider receives the recommendation instead, and what distinguishes those answers from July 2026?

NVISION Eye Centers: A Declining Presence Without Significant Coverage Loss

NVISION Eye Centers' valid recommendation coverage moved from 5.7% in July 2026 to 3.1% in September 2026, down 2.6 points, which the benchmark does not classify as significant. The brand held 8 valid recommendations in September 2026, down from 14 in July 2026.

NVISION's raw mention presence moved from 28.2% to 17.3%, down 10.9 points. Its rank-one rate actually improved from 0.8% to 1.2%, with 3 rank-one recommendations in September 2026.

The notable pattern is that NVISION's presence decline was much larger in percentage-point terms than its coverage decline, and its rank-one credit rose even as its overall presence fell. The brand appears less often across AI answers but holds a slightly stronger position when it does appear.

Highest-priority diagnostic: Which surfaces drove NVISION's presence decline, and did the loss concentrate in prompts where the brand was mentioned but not recommended?

The LASIK Vision Institute: The Largest Coverage Decline Without a Significant Flag

The LASIK Vision Institute's valid recommendation coverage moved from 22.6% in July 2026 to 16.1% in September 2026, a 6.5-point drop, the largest absolute decline in the category. The benchmark does not classify this move as significant, given the brand's volatility range.

The brand's raw mention presence fell from 56.9% to 44.9%, down 12.0 points. Its top-three rate moved from 15.3% to 12.2%, and its rank-one rate from 5.7% to 3.9%. The LASIK Vision Institute recorded 41 valid recommendations in September 2026, down from 56 in July 2026.

The LASIK Vision Institute's presence decline exceeded the coverage decline in percentage-point terms, and the notable gaps analysis shows the gap between this brand and several smaller brands narrowing every month since July. The data does not establish whether the brand's losses flowed to LasikPlus, to mid-tier brands, or out of the recommendation set entirely.

Highest-priority diagnostic: Which prompt and surface combinations drove The LASIK Vision Institute's declines, and which competitor gained the recommendation credit it lost?

Category Level: Presence Declines Larger Than Coverage Declines

The largest percentage-point movements in September 2026 were in raw mention presence, not valid recommendation coverage. The LASIK Vision Institute's presence fell 12.0 points from baseline, NVISION Eye Centers' fell 10.9 points, and TLC Laser Eye Centers' fell 14.7 points, with TLC also recording a significant coverage decline.

The collection universe also shifted between months, from 800 prompt-surface observations in August 2026 to 587 in September 2026. The data does not establish whether the broad presence declines reflect platform behavior or measurement effects across a different prompt set.

Highest-priority diagnostic: What changed in the prompt mix or surface distribution between July 2026 and September 2026 that reduced brand mentions for the largest presence decliners, and did those changes concentrate in particular AI surfaces?

Buyer-Intent Interpretation

In September 2026, all 254 qualified observations fell into the Brand Recommendation cluster. There were no qualified observations in the Pricing & Value or Multi-Brand Comparison clusters, consistent with July and August 2026. The public benchmark, therefore, cannot yet answer which provider AI systems recommend on the basis of price or value, nor which provider wins in explicit head-to-head comparisons. Those questions remain open for a deeper, company-level analysis.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations across the benchmark's defined AI/search surface universe, including the query, the surface, the recommendation outcome, the rank, the sentiment, and citations where exposed. Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• The qualified analysis set (254 observations in September 2026) is smaller than the raw collection universe (587 prompts); percentages are calculated within the qualified set.
• Several brands have very small counts (e.g., ClearSight LASIK at 0 valid recommendations, LASIK MD at 1, Kraff Eye Institute at 4); single-digit percentage movements for these brands represent only one or two observations.
• Movement between months identifies changes worth investigating; it does not by itself establish the cause of those changes.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

The aggregate percentages in this report raise more questions than they answer. Which high-intent prompts does LasikPlus win, and which does The LASIK Vision Institute still take? When TLC Laser Eye Centers loses a recommendation, which competitor appears in its place? What attributes do AI systems associate with each provider, and which external sources shape those answers? These are the questions beneath the 21.6% versus 16.1% headline.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It answers why a brand gained or lost coverage and what to do about it.
