In eye care, the source AI answers cite most is not a private clinic at all: it is the Singapore National Eye Centre. This chapter measures AI search for eye clinics in Singapore in November 2026 on a thin panel of 10 questions per engine, so read it as indicative. Atlas Eye Specialist Centre has the highest composite citation score, 75.0 out of 100. Eagle Eye Centre, the first private clinic in Google’s results for “lasik singapore”, shares fifth place (=5) with three other clinics.
Questions in the panel include “How much does cataract surgery cost in Singapore?” and “Is LASIK painful in Singapore?”.

Atlas Eye Specialist Centre also has the most raw citations, 13 across the four scored engines, two more than Lang Eye Centre. Five of the 20 clinics are cited on all four engines and two on none. The Straits Eye Centre trades under more than one domain, and two of them are in this table.
Three findings
A public eye centre out-cites every private clinic
The Singapore National Eye Centre (snec.com.sg) is the sole most-cited domain on ChatGPT, Perplexity, Google AI Overviews and Google AI Mode. On ChatGPT it has 9 listed citations across the 10 stored answers. No clinic is the most-cited domain, alone or jointly, on any of the four scored engines. On Gemini two directories share first place on 3 each: singapore-medical.com and health365.sg.
Read the supporting analysis
The four scored engines’ top-15 domain lists hold 177 citations. Eye businesses’ own websites take 90 of them (51%), government and public institutions 45 (25%), aggregators 31 (18%), and forums and social platforms 9 (5%).
Google and AI pick many of the same private clinics
Nine clinics came in through Google’s recorded organic results; seven of them also qualified on AI citations. Six of the composite top 10 came in through Google. Atlas Eye Specialist Centre is fifth on Google for “lasik singapore” and has the highest composite score; Lang Eye Centre, sixth on Google, shares second place.
Read the supporting analysis
Eagle Eye Centre, Google’s first clinic for that term at organic position 3 behind SNEC and NUH, shares =5 at 37.5. Both clinics with no citations on the four scored engines came in through “eye clinic singapore”.
Each engine keeps its own shortlist
The Straits Eye Centre has 4 ChatGPT citations and none on Gemini. Eagle Eye Centre has 6 listed AI Overview citations, summed across its www and non-www addresses, and none on ChatGPT. EyeWise Vision Clinic is cited by Perplexity alone, 4 times. In a 10-question panel, one engine’s habits can move a clinic several places.
Who AI cites instead
Public institutions lead. Besides SNEC, ChatGPT cites NUH (5 citations), NUHS (3) and NHG (3). The private hospital group Raffles Medical gets 3 ChatGPT citations, and LinkedIn also gets 3.
Directories and health publishers fill much of the rest. bestdoctors.sg has 4 ChatGPT citations. Health365 is cited by Gemini (3) and Perplexity (3 on its .sg site and 3 on .asia). singapore-medical.com is cited by Gemini (3) and AI Overviews (4). AI Overviews also cite Facebook 6 times. On Copilot (recorded, not scored), the review site bestthingreview.com shares first place on 3 with two clinic sites.

In Ahrefs’ 11 October 2026 snapshot for “eye clinic singapore”, KK Women’s and Children’s Hospital is first. The Straits Eye Centre’s Parkway East site is second and was not cited in this panel on any of the six engines.
Technical readiness
Of the 20 clinics:
- 11 of 20 publish an llms.txt file.
- Fewer than three put up a barrier to AI crawlers, by refusing a request that names GPTBot. None bars any AI crawler from its homepage in robots.txt.
- 17 of 20 have JSON-LD structured data on the homepage.
- 11 of 20 use LocalBusiness-type schema, and 4 of 20 have FAQ schema.
Counts only, from one homepage check on 14 November 2026.
The eye care playbook
Each move below is a test to run and track, not a result this study measured.
→ Separate private procedure fees from booking information. 4 of the 10 questions ask what something costs, and cataract surgery comes up in 3. A page that gives a fee range in Singapore dollars, apart from the booking form, is worth testing.
→ Plan around the public sites. SNEC has 9 ChatGPT citations across 10 answers. A private clinic’s pages need to cover what a public page does not, such as private fees and how to book.
→ Measure each engine on its own. Eagle Eye Centre’s 6 AI Overview citations and none on ChatGPT would vanish in an average.
How this was measured
We took all 10 eye care and LASIK questions with local or buying intent in Ahrefs Brand Radar’s Singapore prompt database and counted the citations to each clinic’s website in the stored answers from ChatGPT, Gemini, Perplexity and Google AI Overviews (AI Mode and Copilot recorded, not scored). The 20 clinics are every eligible clinic in Google’s recorded results for “lasik singapore” and “eye clinic singapore”, plus the clinics AI cites most. With fewer than 15 questions the panel is indicative, and one or two citations either way is not meaningful. Measured, not modelled; pulled 14 November 2026. Full methodology.
