OKAP, FRCOphth and ICO Exams: Formats and How to Prepare with RPC Rounds

OKAP, FRCOphth and ICO Exams: Formats and How to Prepare with RPC Rounds

Last updated: October 2026

Short answer: the OKAP (American Academy of Ophthalmology), FRCOphth (Royal College of Ophthalmologists, UK) and ICO examinations test the same core ophthalmology, but in different formats. This page summarises each exam from its official information and shows which RPC Rounds articles help with which part. RPC Rounds is written mainly for Indian MS/DNB residents. It is not an official or complete review course for any of these exams, so use it alongside the recommended textbooks and the exam's own syllabus.

Exam formats were checked against the official AAO, RCOphth and ICO websites in October 2026. Formats, fees and dates change, so always confirm on the official site before you register.

OKAP: the 13 BCSC sections and where to start on RPC Rounds

OKAP questions are spread equally across the 13 sections of the AAO's Basic and Clinical Science Course (BCSC). The coverage column is our honest estimate of how much RPC Rounds offers for each section.

BCSC sectionRPC Rounds coverageStart with
1. Update on General MedicineLimitedGiant cell arteritis, thyroid eye disease, Behçet disease, ocular drug reactions
2. Fundamentals and Principles of OphthalmologyPartialBasic sciences, ocular pharmacology, blood-ocular barrier, genes and eye diseases
3. Clinical Optics and Vision RehabilitationGood for clinical refractionRetinoscopy, Jackson cross-cylinder, duochrome, Prentice's rule, vertex distance, visual impairment levels
4. Ophthalmic Pathology and Intraocular TumorsLimitedOcular tumours, iris nodules, retinoblastoma genetics
5. Neuro-OphthalmologyGoodNeuro-ophthalmology hub, optic neuritis vs NAION vs AAION, anisocoria, field defects
6. Pediatric Ophthalmology and StrabismusGoodPaediatric hub, strabismus, ROP (ICROP3), amblyopia
7. Oculofacial Plastic and Orbital SurgeryPartialOculoplasty hub, ptosis tests, orbital fracture, congenital NLD obstruction

9. Uveitis and Ocular InflammationGoodUveitis hub, uveitis work-up, VKH, masquerade syndromes
10. GlaucomaGoodGlaucoma hub, gonioscopy grading, target IOP, CCT and IOP
11. Lens and CataractGoodLens hub, phaco step by step, biometry rules of thumb, IOL formulas

FRCOphth: each part and how RPC Rounds can help

PartOfficial formatUseful RPC Rounds articles
Part 1 FRCOphthTwo multiple-choice papers of 90 questions each, two hours per paper, on the same day. Tests basic and clinical sciences and understanding of patient investigations; no clinical component.Basic sciences, pharmacology, retinal layers, electro-oculography. Coverage of anatomy, pathology and statistics is limited, so rely on textbooks for these.
Refraction CertificateA practical exam. The October 2025 New Delhi sitting had 10 OSCE stations: simulated retinoscopy (4), non-cycloplegic retinoscopy (2), subjective refraction (sphere and cylinder), lens neutralisation, and binocular balancing.Retinoscopy tips, JCC, duochrome, optics lectures. Reading is no substitute for practising on real patients and a model eye.
Part 2 WrittenTwo multiple-choice papers of 90 questions each, delivered online, usually twice a year. Tests applied clinical knowledge across the curriculum.Use the learning dashboard by subspecialty, plus landmark trials and gradings and staging systems.
Part 2 OralA structured viva (five 10-minute stations: investigations and data interpretation; two patient management stations; attitudes, ethics and responsibilities; audit, research, evidence-based practice and health promotion) and an OSCE (five 20-minute clinical stations: anterior segment; glaucoma and lid; posterior segment; strabismus and orbit; neuro-ophthalmology; plus a communication skills station).History and case presentation, reading an OCT, reading a visual field, emergencies on call, spot the diagnosis. The ethics and UK practice stations are not covered here.

ICO examinations: each paper and how RPC Rounds can help

PaperOfficial formatUseful RPC Rounds articles
Visual Sciences (Part A)120 single-best-answer questions in three hours. Anatomy of the eye and orbit, neuro-anatomy, physiology, biochemistry and cell biology, epidemiology and statistics, pathology and microbiology.Basic sciences, layers in ophthalmology, genetics firsts, microbial keratitis. Limited coverage; textbooks are essential.
Optics, Refraction and Instruments (Part B)60 single-best-answer questions in one and a half hours.Prentice's rule, vertex distance, duochrome, formulas in ophthalmology, instruments
Clinical Ophthalmology (Part C)Offered after passing Visual Sciences and ORI (or a recognised equivalent).Every subspecialty hub, the learning dashboard and the clinical pearls with self-test quizzes
Advanced ExaminationTaken after the three Standard Examinations. Passing it together with a local face-to-face examination allows use of the post-nominal FICO.Landmark trials, gradings, diagnostic criteria, classifications

One change to note: the ICO states that from 1 January 2028 the Royal College of Physicians and Surgeons of Glasgow will no longer accept ICO examination qualifications as exemptions for its FRCS Ophthalmology examinations.

A practical study approach

  • Use the official syllabus as your checklist. Tick off each topic as you cover it, from any source.
  • Build on Indian MS/DNB preparation. The clinical content overlaps heavily; the differences are mainly in format and in UK or US practice guidelines.
  • Practise the format. Single-best-answer questions reward reading every option; OSCEs reward a structured, spoken examination routine.
  • Test yourself regularly. Try the clinical pearls quizzes, the gradings flip cards and the RPC question bank.

Frequently asked questions

Can Indian residents take the OKAP?

The standard OKAP is for residents in US and Canadian programmes. The AAO's OKAP International uses the same 260-question format, is open to residents and practising ophthalmologists worldwide, and is taken with remote proctoring. Check the AAO website for eligibility and fees for your country.

How many questions are in Part 1 FRCOphth?

Two multiple-choice papers of 90 questions each, two hours per paper, taken on the same day.

What does the FRCOphth Refraction Certificate involve?

It is a practical OSCE. The October 2025 New Delhi sitting had 10 stations covering simulated and non-cycloplegic retinoscopy, subjective refraction, lens neutralisation and binocular balancing.

How do you get FICO?

By passing the ICO Standard Examinations, then the Advanced Examination together with a local face-to-face ophthalmology examination.

Is RPC Rounds enough to pass these exams?

No. It is a free teaching blog that covers much of the clinical content, but it does not replace the official syllabus, standard textbooks or practice in each exam's format.
