NBEO Part III study plan

NBEO Part III · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Visual Acuity and Refraction Procedures & Ophthalmic Optics and Lensometry

  • Perform and narrate a full subjective refraction sequence (sphere, cylinder, axis, binocular balance) on a partner in under 15 minutes

  • Demonstrate streak retinoscopy on a schematic eye and on a partner, correctly neutralizing both meridians and recording the working-distance correction

  • Read and verify 20 lens powers with a manual lensometer, including spherocylinders, prism, and axis orientation, to within 0.125 D

  • Explain and demonstrate vertex distance conversion and its effect on high-power lenses

  • Convert 15 prescriptions between plus-cylinder and minus-cylinder notation without error

Your checkpoint

A timed video or self-scored checklist log of 5 complete refractions plus 20 lensometry readings with a written error tally

Week 2

Anterior Segment Evaluation and Slit Lamp Techniques & Ocular Pharmacology and Medication Administration

  • Set up and align a slit lamp from scratch, adjusting illumination, magnification, and patient positioning independently

  • Execute diffuse, direct focal, retroillumination, sclerotic scatter, and Van Herick techniques on 10 patients or partners

  • Grade corneal edema, cells and flare, and anterior chamber angle depth using standardized scales

  • Prepare and instill topical anesthetic, fluorescein, and mydriatic drops with correct technique and documentation

  • State the mechanism, concentration, and key contraindication for each topical diagnostic drug used in the exam room

Your checkpoint

A completed slit lamp technique checklist for 10 examinations with anterior chamber grading recorded for each

Week 3

Binocular Vision and Ocular Motility Testing & Visual Field Assessment

  • Measure and record cover test at distance and near, including alternate cover, with prism neutralization of deviations

  • Perform near point of convergence, vergence ranges, and stereopsis testing and interpret results against normative values

  • Administer a confrontation visual field and grade the result, then explain when it triggers formal perimetry

  • Set up and run a 24-2 SITA Standard visual field, coaching the patient for reliable fixation and catch trials

  • Interpret reliability indices and identify glaucomatous versus neurologic field patterns in 10 sample printouts

Your checkpoint

A written interpretation of 10 visual field printouts (5 glaucomatous, 5 neurologic or artifact) with reliability assessment for each

Week 4

Posterior Segment and Fundus Evaluation & Intraocular Pressure and Glaucoma Assessment

  • Perform direct ophthalmoscopy on 10 undilated and dilated eyes, describing disc, cup, macula, vessels, and periphery systematically

  • Grade cup-to-disc ratio and identify glaucomatous disc features such as rim thinning, notching, and hemorrhage

  • Measure intraocular pressure by Goldmann applanation with correct mire alignment, fluorescein dosing, and calibration checks

  • Perform and interpret a four-mirror gonioscopy examination using the Shaffer grading system

  • Explain the indications and technique for dilated fundus examination and recognize when dilation is contraindicated

Your checkpoint

A fundus drawing and IOP record for 10 eyes, including cup-to-disc ratio and gonioscopy grade for each

Week 5

Contact Lens Fitting and Evaluation & Patient Communication, Professionalism, and Safety

  • Collect keratometry, refraction, and corneal topography data and select an appropriate initial soft lens parameter set

  • Evaluate soft lens fit by centration, coverage, movement, and push-up test, and document the fit assessment

  • Teach a patient proper insertion, removal, and care system use, and verify understanding with teach-back

  • Deliver a full informed-consent conversation covering risks, alternatives, and after-hours contact procedures

  • Demonstrate hand hygiene, instrument disinfection, and safe handling of body fluids during a simulated exam

Your checkpoint

A complete contact lens fitting record and a scored teach-back and informed-consent role-play with a partner

Week 6

Patient History and Interviewing & Patient Communication, Professionalism, and Safety

  • Conduct a structured case history covering chief complaint, ocular history, medical history, medications, and family history in under 10 minutes

  • Ask targeted follow-up questions that convert a vague complaint into a specific differential

  • Adapt interview technique for pediatric, elderly, hearing-impaired, and non-English-speaking patients

  • Document a case history in a problem-oriented format suitable for a clinical record

  • Identify red-flag symptoms that require urgent referral and state the appropriate action for each

Your checkpoint

Three written case histories from role-played patients, each with a problem list and differential, reviewed against a rubric

Week 7

Visual Acuity and Refraction Procedures & Binocular Vision and Ocular Motility Testing & Anterior Segment Evaluation and Slit Lamp Techniques

  • Run a complete integrated entrance-to-exit examination sequence on a partner within 45 minutes

  • Recover smoothly from a missed finding by re-sequencing the exam without losing time

  • Perform retinoscopy, refraction, cover test, and slit lamp in one continuous flow with correct handoffs

  • Narrate clinical findings aloud while performing each procedure as required in a practical exam format

Your checkpoint

Two full timed mock practical examinations with a checklist score and a written list of three fixes for the next attempt

Week 8

Posterior Segment and Fundus Evaluation & Intraocular Pressure and Glaucoma Assessment & Visual Field Assessment & Contact Lens Fitting and Evaluation & Ophthalmic Optics and Lensometry & Ocular Pharmacology and Medication Administration & Patient Communication, Professionalism, and Safety

  • Rotate through every domain in 15-minute stations to rebuild retention across all 11 areas

  • Re-drill the weakest three procedures identified in week 7 until performed correctly twice in a row

  • Rehearse professional communication, infection control, and emergency response scenarios under time pressure

  • Complete a final self-assessment and list remaining gaps with a plan for the week before the exam

Your checkpoint

A full-length mock practical with station-by-station scores and a one-page gap-closing plan
